Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments. In the drawings, the same or corresponding portions are denoted by the same reference characters and description thereof will not be repeated. In addition, the description may be omitted as appropriate also for the part where the description is duplicated.

Embodiment 1
FIG. 1 is a top view of the disinfecting solution spreading device 1 according to the first embodiment. As shown in FIG. 1, the disinfecting solution spreading device 1 has a delivery port 1 a. The sterilizing solution spraying apparatus 1 sends out a mist of the sterilizing solution from the delivery port 1 a and sprays the sterilizing solution on the bathroom.

In addition, as shown in FIG. 1, the disinfecting liquid dispersion device 1 includes a first unit 10 and a second unit 20. In the present embodiment, the delivery port 1 a is a gap formed between the first unit 10 and the second unit 20.

The first unit 10 includes a blower 11, a support 12, a supply pipe 13, a faucet 14, and a control valve 15.

The blower 11 blows the mist of the disinfecting solution. In the present embodiment, the blower 11 includes a plurality of blades 111 and a fan motor 112. The fan motor 112 rotates the plurality of blades 111. By rotating the plurality of blades 111, a wind is generated and the mist of the disinfecting solution is blown. The blower 11 is, for example, a DC fan. When the blower 11 is a DC fan, adjustment of the rotational speed of the fan motor 112 is facilitated. In other words, adjustment of the air flow rate of the air blower 11 is facilitated.

The support 12 supports the blower 11 and the second unit 20. In the present embodiment, the support 12 includes a main body portion 121 and a plurality of support members 122.

The main body portion 121 supports the blower 11. In the present embodiment, the main body portion 121 includes the lid 121 a, and the lid 121 a supports the blower 11. Preferably, the lid 121a supports the blower 11 at a central portion. By disposing the blower 11 at the central portion of the lid 121 a, the mist of the bactericidal solution can be radially delivered from the bactericidal solution scatterer 1 centering on the bactericidal solution scatterer 1. In other words, it is possible to suppress that the mist of the disinfecting solution is biased and delivered in a specific direction. Therefore, the mist of the disinfecting solution can be delivered without being biased in a specific direction, and a wider range can be disinfected.

The plurality of support members 122 protrude outward from the main body portion 121 to support the second unit 20. In the present embodiment, the main body portion 121 has a rectangular shape in plan view, and the support member 122 protrudes from the center of each side of the main body portion 121. The delivery port 1 a is formed around the main body portion 121. Specifically, the delivery port 1 a is formed between the plurality of support members 122. In the present embodiment, the delivery port 1a is L-shaped in plan view, and the bacteriostatic solution spreader 1 has four delivery ports 1a. The mist of the bactericidal solution can be delivered from substantially the entire circumference of the main body 121 by the four delivery ports 1a.

The supply pipe 13 supplies water to the second unit 20. For example, the supply pipe 13 supplies tap water. The faucet 14 is provided in the supply pipe 13. The faucet 14 can be opened and closed. When the faucet 14 is in the open state, the supply pipe 13 can supply water. When the faucet 14 is in the closed state, the supply of water by the supply pipe 13 is shut off. In the present embodiment, the faucet 14 is disposed on the lid 121 a. The adjustment valve 15 is provided to the supply pipe 13. The adjusting valve 15 will be described later with reference to FIG.

Then, with reference to FIG. 2, the disinfecting solution spreading device 1 is further demonstrated. FIG. 2 is a cross-sectional view of the disinfecting solution spraying device 1 according to the first embodiment. In detail, FIG. 2 shows a cross section taken along the line II-II in FIG. As shown in FIG. 2, the disinfecting solution scattering device 1 is installed on the ceiling S of the bathroom. Specifically, the first unit 10 is installed on the ceiling S of the bathroom.

Subsequently, the first unit 10 will be further described with reference to FIG. As shown in FIG. 2, the main body 121 of the support 12 has a box shape whose lower surface is opened, and further includes a wall 121 b in addition to the lid 121 a. The wall 121b protrudes downward from the end of the lid 121a. The support member 122 is connected to the lower end portion of the wall portion 121 b. The blower 11 blows air drawn from the outside of the main body portion 121 toward the second unit 20. The supply pipe 13 extends from the lid 121 a of the support 12 to the inside of the second unit 20.

Subsequently, the second unit 20 will be described with reference to FIG. The second unit 20 includes a housing portion 21, an electrode pair 22, an ultrasonic wave generation element 23, a water level sensor 24, and a guide member 25. The delivery port 1a described with reference to FIG. 1 is formed between the upper end of the guide member 25 and the main body 121 (the wall 121b) of the support 12.

The storage unit 21 stores a solvent. In the present embodiment, the solvent is water L. The housing portion 21 has a box shape whose upper surface is open. In the present embodiment, the supply pipe 13 extends to the inside of the housing portion 21.

The electrode pair 22 is immersed in a solvent (water L). In the present embodiment, the electrode pair 22 is disposed on the floor surface of the housing portion 21. By applying a voltage to the electrode pair 22, a disinfectant component is generated in the solvent (water L). As a result, a disinfecting solution in which the solvent (water L) and the disinfecting component are mixed is generated in the storage unit 21. In other words, the storage unit 21 stores the disinfecting solution.

In the present embodiment, the germicidal component is silver ion. Specifically, each of the electrodes constituting the electrode pair 22 is a metal plate made of silver alone. Alternatively, each electrode is a metal plate made of plate-like titanium metal and silver supported on part or all of the surface of titanium metal. For example, the plate size of each of the electrodes constituting the electrode pair 22 is 5 mm × 30 mm (thickness 0.3 mm), the distance between the electrodes is 3 mm, 100 ml of tap water having pH 7.6 and hardness 45 mg / L in the housing portion 21 When housed, when a voltage of 5 V DC is applied to the electrode pair 22, a current of 150 mA or more and 170 mA or less flows between the electrodes, and silver ions are eluted from the anode.

The ultrasonic wave generation element 23 applies ultrasonic vibration to the bacteria removal solution to generate a mist of the bacteria removal solution. Specifically, the ultrasonic wave generating element 23 is disposed on the floor surface of the housing portion 21. In other words, the ultrasonic wave generating element 23 is immersed in the disinfecting solution. The ultrasonic wave generation element 23 irradiates an ultrasonic wave from the inside of the liquid to the liquid surface. As a result, a fountain-like liquid column is generated on the liquid surface due to the sound pressure, and a mist (fog of disinfectant liquid) is generated from the liquid column.

When the disinfecting solution spraying device 1 sprays the disinfecting solution, the water level (height of liquid level) of the disinfecting solution stored in the storage unit 21 fluctuates. When generating a mist by ultrasonic waves, it is necessary to adjust the position (water level) of the liquid level so that the nodes of the ultrasonic waves are located at the liquid level.

The water level sensor 24 detects the position of the liquid surface of the disinfecting solution. The adjustment valve 15 can be opened and closed. When the control valve 15 is open, water is supplied by the supply pipe 13. When the control valve 15 is in the closed state, the water supply by the supply pipe 13 is shut off. The adjusting valve 15 opens and closes based on the detection result of the water level sensor 24, and controls the supply of water from the supply pipe 13 so that the node of the ultrasonic wave is located at the liquid level. The adjustment valve 15 is, for example, a solenoid valve. The water level sensor 24 is, for example, a float switch. When the water level sensor 24 is a float switch, the water level sensor 24 detects whether the node of the ultrasonic wave is located at the liquid level. Specifically, the water level sensor 24 detects whether the water level of the bacteriostatic solution is a predetermined water level. The predetermined water level is set according to the wavelength of the ultrasonic wave.

The guide member 25 has a guide surface 251. Specifically, the inner side surface of the guide member 25 forms a guide surface 251. The guide surface 251 guides the mist of the disinfecting solution to a predetermined surface such that the mist of the disinfecting solution blown by the blower 11 flows along a predetermined surface of the surfaces that partition the bathroom. Specifically, in the present embodiment, the blower 11 generates a wind directed to the liquid surface of the disinfecting solution. The mist of the bactericidal solution is blown toward the guide surface 251 by the wind directed to the liquid surface of the bactericidal solution. As a result, the mist of the sterilizing solution blown by the blower 11 is guided by the guide surface 251 to a predetermined surface.

In the present embodiment, the guide surface 251 guides the mist of the disinfecting solution to the ceiling surface SS of the bathroom. Specifically, the guide member 25 protrudes obliquely upward from the upper end of the side wall of the accommodation portion 21. Therefore, the guide surface 251 is an inclined surface, and is inclined so as to be closer to the ceiling surface SS of the bathroom as it is separated from the accommodation portion 21. As a result, the mist of the disinfecting solution is discharged obliquely upward from the guide surface 251 and flows along the ceiling surface SS. In other words, the mist of the disinfecting solution is delivered obliquely upward from the delivery port 1a. Alternatively, the mist of the disinfecting solution is delivered from the horizontal direction to the upper direction from the guide surface 251 (delivery port 1a). In addition, the mist of the disinfecting solution may be sent out in the horizontal direction from the guide surface 251 (delivery port 1a). For example, when the gap between the upper end of the guide surface 251 and the ceiling surface SS is narrow, the mist of the bacteria removal solution may be discharged in the horizontal direction.

Subsequently, the flow of the mist of the disinfecting solution will be described with reference to FIG. FIG. 3 is a view showing a mist flow of the disinfecting liquid according to Embodiment 1 of the present invention. Arrows D1 to D3 indicate the direction in which the disinfectant solution flows.

As shown in FIG. 3, the mist of the sterilizing solution guided to the ceiling surface SS of the bathroom by the guide surface 251 flows along the ceiling surface SS. In addition, the mist of the bacteriostatic solution led to the wall surface WS of the bathroom along the ceiling surface SS flows downward along the wall surface WS.

In the above, with reference to FIG. 1 to FIG. 3, the disinfectant solution spraying apparatus 1 according to the present embodiment has been described. According to the present embodiment, since the mist of the disinfecting solution flows along the ceiling surface SS (an example of a predetermined surface) of the bathroom, a wider range of the ceiling surface SS can be disinfected. Furthermore, according to the present embodiment, the mist of the bactericidal solution can be radially delivered from the bactericidal solution scattering device 1 centering on the bactericidal solution spraying device 1. Thus, a wider range of the ceiling surface SS can be disinfected.

Further, according to the present embodiment, the mist of the bacteriostatic solution led to the wall surface WS of the bathroom along the ceiling surface SS flows downward along the wall surface WS. Therefore, the disinfecting solution can be sprayed on the wall surface WS of the bathroom.

Further, according to the present embodiment, the mist of the bacteriostatic solution is delivered toward the ceiling surface SS and flows along the ceiling surface SS and the wall surface WS. Therefore, it is possible to prevent a person who gets into the bathroom during spraying of the disinfecting solution from inhaling the fog of the disinfecting solution. Moreover, it can suppress that a bactericidal solution adheres to the person who entered into the bathroom.

Then, with reference to FIG. 4 (a), FIG.4 (b), FIG.5 and FIG. 6, the disinfecting liquid scattering device 1 which concerns on this embodiment is further demonstrated. FIG. 4A is a top view of the second unit 20 according to the first embodiment. FIG. 4B is a bottom view of the second unit 20 according to the first embodiment.

As shown in FIGS. 4 (a) and 4 (b), the second unit 20 has a plurality of support holes 20a. In the present embodiment, the guide member 25 has a plurality of support holes 20a. The support holes 20 a are through holes that penetrate the guide member 25. The plurality of support holes 20 a are formed at positions corresponding to the plurality of support members 122 described with reference to FIG. 1.

Further, in the present embodiment, the guide surface 251 is annular. Since the guide surface 251 is annular, the mist of the bactericidal solution can be radially delivered from the bactericidal solution spray device 1 centering on the bactericidal solution spray device 1. In other words, it is possible to suppress that the mist of the disinfecting solution is biased and delivered in a specific direction. Therefore, the mist of the disinfecting solution can be delivered without being biased in a specific direction, and a wider range can be disinfected.

FIG. 5 is a cross-sectional view of the disinfecting solution spraying device 1 according to the first embodiment. Specifically, FIG. 5 shows a cross section taken along the line VV of FIG. As shown in FIG. 5, the support members 122 of the first unit 10 are respectively inserted into the corresponding support holes 20a. The guide member 25 is supported by the support member 122 as the support member 122 is inserted into the support hole 20 a. In other words, the second unit 20 is supported by the support member 122.

In the present embodiment, the support member 122 detachably supports the guide member 25. In other words, the support member 122 detachably supports the second unit 20. Specifically, at least one of the guide member 25 and the support member 122 is formed of an elastic material. For example, at least one of the guide member 25 and the support member 122 may be formed of acrylic resin. When at least one of the guide member 25 and the support member 122 has elasticity, the support member 122 can be inserted into and removed from the support hole 20a, and as a result, the second unit 20 can be attached and detached.

FIG. 6 is a view showing the second unit 20 separated from the first unit 10. In the present embodiment, the support member 122 detachably supports the second unit 20 (guide member 25). Therefore, as shown in FIG. 6, the second unit 20 can be easily separated from the first unit 10. In other words, the second unit 20 can be easily removed from the ceiling S of the bathroom.

As described with reference to FIG. 2, the blower 11 sucks in air from the outside and blows air, so that dust or the like from the outside is contained in the liquid (water L or the disinfecting solution) contained in the container 21. Dust is easily taken in. Moreover, when the water L is tap water, the scale of tap water may be accumulated in the storage unit 21. Therefore, it is necessary to periodically clean the inside of the second unit 20 from the viewpoint of hygiene. According to the present embodiment, since the second unit 20 can be separated from the first unit 10, the inside of the second unit 20 can be easily cleaned.

Furthermore, when silver ions are used as the bacteria removal component of the bacteria removal solution, the silver ions may be reduced and aggregated to form colloids, which may cause darkening due to the silver colloid around the ultrasonic wave generating element 23. Since the silver colloid may cause the malfunction of the ultrasonic wave generating element 23, it is necessary to periodically clean the inside of the container 21 to remove the silver colloid. According to the present embodiment, since the second unit 20 can be separated from the first unit 10, the inside of the housing portion 21 can be easily cleaned.

In the present embodiment, silver ions are eluted from the anode of the electrode pair 22. For this reason, the anode (electrode) becomes smaller in accordance with the period of use of the disinfectant spraying device 1. Therefore, it is necessary to replace the electrode pair 22 regularly. In the present embodiment, the electrode pair 22 is provided in the housing portion 21. Also, the second unit 20 can be separated from the first unit 10. Therefore, the electrode pair 22 can be easily replaced.

Preferably, both the guide member 25 and the support member 122 are formed of an elastic material. The elasticity of both the guide member 25 and the support member 122 allows the second unit 20 to be separated from the first unit 10 more easily. Further, when removing the second unit 20 from the ceiling S of the bathroom, it is preferable to close the faucet 14 so that water does not drip from the supply pipe 13.

Then, with reference to FIG. 7, the disinfecting solution spreading device 1 is further demonstrated. FIG. 7 is a block diagram of the bacteria removal solution spraying apparatus 1 according to the first embodiment. As shown in FIG. 7, the disinfecting liquid dispersion device 1 further includes an operation unit 30, a control device 40, and first to fourth power devices 41 to 44.

The operation unit 30 receives a user's operation. The operation unit 30 transmits, to the control device 40, a signal corresponding to the user's operation. The operation unit 30 is installed on, for example, a wall surface of a bathroom or a wall surface of a changing room adjacent to the bathroom.

In the present embodiment, the operation unit 30 includes a sterilization button 31, a stop button 32, and a display 33. The operation unit 30 also includes a processor, a semiconductor memory, and an interface circuit. The processor is, for example, a central processing unit (CPU) or a micro processing unit (MPU). The operation unit 30 includes, for example, a random access memory (RAM) and a read only memory (ROM) as a semiconductor memory. The processor executes various processes in accordance with a control program (computer program) stored in the semiconductor memory. The interface circuit performs communication between the operation unit 30 and the control device 40.

The sterilization button 31 is a button for instructing the start of the sterilization operation. That is, when the user presses the sterilization button 31, the operation unit 30 transmits a signal instructing start of the sterilization operation to the control device 40. When the control device 40 receives a signal instructing the start of the sterilization operation, the sterilization liquid dispersion apparatus 1 executes the sterilization operation for a predetermined period.

The stop button 32 is a button for instructing stop of the bacteria removal operation. That is, when the user presses the stop button 32, the operation unit 30 transmits a signal instructing stop of the sterilization operation to the control device 40. When the control device 40 receives a signal instructing to stop the sterilization operation, the sterilization liquid dispersion device 1 stops the sterilization operation even before a predetermined period has elapsed since the start of the sterilization operation. Do.

The display 33 is controlled by the processor to display various information. For example, the display 33 displays a message indicating that the sterilization operation is being performed, when the sterilization solution dispersion device 1 is performing the sterilization operation. Further, for example, the display 33 displays the time elapsed from the start of the sterilization operation, or the remaining time until the sterilization operation ends.

The control device 40 controls the operation of the bacteriostatic solution spraying device 1. Specifically, the control device 40 includes a processor, a semiconductor memory, and an interface circuit. The processor is, for example, a CPU or an MPU. The control device 40 includes, for example, a RAM and a ROM as a semiconductor memory. The processor executes various processes in accordance with a control program (computer program) stored in the semiconductor memory. The interface circuit executes communication between the control device 40 and the operation unit 30. In the present embodiment, when the control device 40 receives from the operation unit 30 a signal instructing start of the sterilization operation, the operations of the first to fourth power supply devices 41 to 44 are performed such that the sterilization operation is performed. Control.

The first power supply device 41 is controlled by the control device 40 to generate a voltage for energizing the electrode pair 22. Specifically, the control device 40 controls the first power supply device 41 such that the electrode pair 22 is energized until the concentration of silver ions reaches a predetermined concentration.

The second power supply device 42 is controlled by the control device 40 to generate a voltage for driving the ultrasonic wave generation element 23. As a result, an ultrasonic wave is generated from the ultrasonic wave generating element 23.

The third power supply device 43 is controlled by the control device 40 to generate a voltage for driving the fan motor 112. As a result, the plurality of blades 111 described with reference to FIG. 1 rotate to generate a wind for blowing the mist of the disinfecting solution. It is preferable that the control device 40 periodically change the air flow rate of the air blower 11 by periodically changing the rotation speed of the fan motor 112. By changing the air blowing amount of the air blower 11, the mist scattering distance of the bacteria removal solution can be changed, and the bacteria removal solution can be uniformly attached to the ceiling surface SS and the wall surface WS.

The fourth power supply device 44 is controlled by the control device 40 to generate a voltage for driving the adjustment valve 15. Specifically, the control device 40 controls the fourth power supply device 44 based on the output of the water level sensor 24 so that the water level of the bacteriostatic solution becomes a predetermined water level. Specifically, when the level of the disinfecting solution is lowered due to the disinfecting operation, the control device 40 opens the control valve 15. As a result, as described with reference to FIG. 2, water is supplied to the storage unit 21 from the supply pipe 13. Further, the control device 40 closes the control valve 15 when the water level of the bacteriostatic solution rises to a predetermined water level.

Subsequently, the flow of processing performed by the control device 40 will be described with reference to FIGS. 7 and 8. FIG. 8 is a flowchart showing processing performed by the control device 40 according to the first embodiment. When the control device 40 receives from the operation unit 30 a signal instructing start of the sterilization operation, the control device 40 starts the process shown in FIG.

As shown in FIG. 8, when the control device 40 receives a signal instructing the start of the sterilization operation, first, the electrode pair 22 is energized so that the concentration of silver ions becomes a predetermined concentration (step S1).

After energizing the electrode pair 22, the control device 40 generates an ultrasonic wave from the ultrasonic wave generation element 23 (step S2). Further, the control device 40 drives the fan motor 112 to generate a wind for blowing the mist of the disinfecting solution (step S2). As a result, the mist of the disinfecting solution is delivered from the delivery port 1 a described with reference to FIGS. 1 and 2.

When the control device 40 starts sending out the mist of the disinfecting solution, it determines whether the water level of the disinfecting solution is a predetermined water level or not based on the output of the water level sensor 24 (step S3).

If the controller 40 determines that the water level of the bacteria removal solution is a predetermined water level (Yes in step S3), it determines whether a predetermined period has elapsed since the signal instructing start of the bacteria removal operation has been received. (Step S4).

On the other hand, when the control device 40 determines that the water level of the bactericidal solution is not the predetermined water level (No in step S3), it drives the adjusting valve 15 so that the water level of the bactericidal solution becomes the predetermined water level (step S5) . In other words, as described with reference to FIG. 2, the control device 40 supplies water from the supply pipe 13 to the storage unit 21 to raise the water level of the disinfecting solution to a predetermined water level.

When the water level of the bacteriostatic solution rises to a predetermined water level, the control device 40 closes the control valve 15, and then turns on the electrode pair 22 so that the concentration of silver ions becomes a predetermined concentration (step S6). After energizing the electrode pair 22, the control device 40 determines whether or not a predetermined period has elapsed after receiving a signal instructing start of the sterilization operation (Step S4).

If control device 40 determines that the predetermined period has not elapsed (No in step S4), the process returns to the process in step S3. On the other hand, when the control device 40 determines that the predetermined period has elapsed (Yes in step S4), the process illustrated in FIG. 8 ends.

In the above, with reference to FIG.7 and FIG.8, the flow of the process which the control apparatus 40 performs was demonstrated. According to the process shown in FIG. 8, the concentration of silver ions in the disinfecting solution can be maintained at a predetermined concentration, and the disinfecting solution can be dispersed in the bathroom.

Subsequently, the flow of another process executed by the control device 40 will be described with reference to FIGS. 7 and 9. FIG. 9 is a flowchart illustrating another example of the process performed by the control device 40 according to the first embodiment. When the control device 40 receives a signal instructing start of the sterilization operation from the operation unit 30, it starts the process shown in FIG. Hereinafter, points different from the process shown in FIG. 8 will be described.

As shown in FIG. 9, when the control device 40 determines that the water level of the disinfecting solution is a predetermined water level (Yes in step S3), the first predetermined is received after the signal instructing start of the bacteria removal operation is received. It is determined whether a period has passed (step S11).

Further, when the control device 40 drives the adjusting valve 15 to return the water level of the bacteria removal liquid to a predetermined water level (step S5), a second predetermined period is received after the signal instructing start of the bacteria removal operation is received. It is determined whether it has elapsed (step S12). The second predetermined period is a period shorter than the first predetermined period.

When determining that the second predetermined period has not elapsed (No in step S12), the control device 40 energizes the electrode pair 22 so that the concentration of silver ions becomes a predetermined concentration (step S6). On the other hand, when determining that the second predetermined period has elapsed (Yes in step S12), the control device 40 does not cause the electrode pair 22 to be energized. Therefore, after the second predetermined period has elapsed, the concentration of silver ions decreases each time water is supplied from the supply pipe 13 to the storage unit 21.

In the present embodiment, the second predetermined period is set so that the liquid stored in the storage unit 21 returns from the disinfecting solution to the normal water L before the first predetermined period elapses. Therefore, before the first predetermined period elapses, the ultrasonic wave generation element 23 applies ultrasonic vibration to the water L to generate a mist of water, and the blower 11 blows the mist of the water L.

In the above, with reference to FIG.7 and FIG.9, the flow of the other process which the control apparatus 40 performs was demonstrated. According to the process shown in FIG. 9, after a disinfecting solution is attached to the ceiling surface SS or the wall surface WS, water is attached to the ceiling surface SS or the wall surface WS to maintain the sterilization effect by silver ions for a long time Can. Specifically, when the bactericidal solution is dried, silver colloid precipitates. Silver colloid has a small disinfecting effect on mold and general bacteria. Therefore, in order to maintain the sterilization effect by the silver ion adhering to the ceiling surface SS and the wall surface WS for a long time, it is necessary to prevent the drying of the sterilization solution. On the other hand, according to the process shown in FIG. 9, the drying of the bacteriostatic solution adhering to the ceiling surface SS or the wall surface WS can be prevented. Therefore, the sterilization effect by the silver ion adhering to ceiling surface SS or wall surface WS can be maintained for a long time.

Furthermore, when the bacteria removal solution is dried and silver colloid is deposited, darkening by the silver colloid occurs on the ceiling surface SS and the wall surface WS, and the appearance becomes worse. On the other hand, according to the process shown in FIG. 9, the drying of the bacteriostatic solution adhering to the ceiling surface SS or the wall surface WS can be prevented. Thus, the occurrence of darkening can be suppressed.

In the process shown in FIG. 9, water is usually sprayed after spraying of the bacteria removal solution. However, normal water may be sprayed after a predetermined period of time has elapsed after spraying of the bacteria removal is completed. In this case, even if the bacteriostatic solution is dried to precipitate silver colloid, the silver colloid can be dissolved to generate silver ions. In addition, even if darkening occurs, the darkening can be made less noticeable by dissolving the silver colloid.

Then, with reference to FIG. 10 (a) and FIG.10 (b), the electricity supply time of the electrode pair 22 is demonstrated. FIG. 10 (a) is a graph showing the time change of the silver ion concentration. FIG. 10 (b) is a graph showing the sterilization effect of silver ions.

In FIG. 10 (a), the vertical axis indicates the silver ion concentration, and the horizontal axis indicates the elapsed time. More specifically, FIG. 10A shows a silver ion concentration measured by storing 100 ml of tap water having a pH of 7.6 and a hardness of 45 mg / L in the containing portion 21 and applying a voltage of 5 VDC to the electrode pair 22. The plate size of each electrode constituting the electrode pair 22 was 5 mm × 30 mm (thickness 0.3 mm). Moreover, the distance between electrodes was 3 mm. As shown in FIG. 10A, the silver ion concentration reached 500 ppb in 3 minutes of elapsed time. In addition, the silver ion concentration became 1000 ppb or more in an elapsed time of 5 minutes.

In FIG. 10 (b), the vertical axis indicates the sterilization rate, and the horizontal axis indicates the silver ion concentration. Moreover, in FIG.10 (b), the graph of x mark shows the elimination rate of Staphylococcus aureus, and the graph of a black circle shows the elimination rate of black mold. As shown in FIG. 10 (b), general bacteria (eg, S. aureus) can be eradicated by 90% or more by silver ions at a concentration of 50 ppb or more and 100 ppb or less. In addition, black mold (cladosporium) can be sterilized by 90% or more by silver ions having a concentration of 400 ppb or more and 500 ppb or less.

Therefore, by energizing the electrode pair 22 for about 3 minutes, it is possible to elute silver ions capable of disinfecting general bacteria and fungi.

The first embodiment has been described above. According to the first embodiment, the disinfecting solution can be uniformly attached to the ceiling surface SS and the wall surface WS of the bathroom without being biased to a specific range.

In the present embodiment, the guide surface 251 is an inclined surface, but the guide surface 251 may include a horizontal surface. For example, the guide surface 251 may include a horizontal surface parallel to the ceiling surface SS. In this case, the mist of the sterilizing solution is discharged from the guide surface 251 in the horizontal direction and flows along the ceiling surface SS.

Further, in the present embodiment, the bacteria removal solution spraying apparatus 1 has four L-shaped delivery ports 1a, but the number and the shape of the delivery ports 1a are not particularly limited.

In addition, in the disinfecting solution spreading device 1 shown to Fig.11 (a), the mist of a disinfecting solution may be sent out upwards from the sending port 1a. For example, when the delivery port 1a is far from the outer edge of the buttocks 124, the mist of the disinfecting solution may be delivered upward.

Moreover, in this embodiment, although the external shape of the guide member 25 (2nd unit 20) was planar view rectangular shape, the external shape of the guide member 25 (2nd unit 20) is not specifically limited. FIG. 11 (b) is a view showing another modified example of the bacteria removal solution spraying apparatus 1 according to the first embodiment. As shown in FIG. 11B, the outer shape of the guide member 25 (second unit 20) may be circular in plan view. When the outer shape of the guide member 25 is circular, screw grooves corresponding to each other may be formed on the inner side surface of the guide member 25 and the outer peripheral surface of the flange portion 124 of the support 12. That is, the guide unit 25 may be supported by the collar portion 124 of the support 12 by rotating the second unit 20.

Further, in the present embodiment, the main body portion 121 of the support 12 is rectangular in a plan view, but the outer shape of the main body portion 121 is not particularly limited. For example, as shown in FIG. 11 (b), the outer shape of the main body portion 121 may be circular in plan view.

Subsequently, Embodiment 2 of the present invention will be described with reference to FIG. However, items different from the first embodiment will be described, and description of the same items as the first embodiment will be omitted. The second embodiment differs from the first embodiment in the position of the electrode pair 22.

FIG. 12 is a cross-sectional view of the disinfecting solution spraying device 1 according to the second embodiment. As shown in FIG. 12, the second unit 20 includes a support member 26 connected to the inner side surface of the housing portion 21. The support member 26 supports the electrode pair 22. Specifically, the support member 26 supports the electrode pair 22 so that the electrode pair 22 is positioned directly above the ultrasonic wave generation element 23. By positioning the electrode pair 22 directly above the ultrasonic wave generation element 23, ultrasonic vibration can be applied to the bacteriostatic solution between the two electrodes constituting the electrode pair 22.

The second embodiment has been described above. According to the second embodiment, ultrasonic vibration can be applied to the sterilizing solution between two electrodes. Therefore, it is possible to prevent the silver colloid from adhering to the electrodes by oscillating the disinfecting solution between the two electrodes.

Third Embodiment
A third embodiment of the present invention will now be described with reference to FIGS. 13 and 14. However, matters different from the first and second embodiments will be described, and the description of the same matters as the first and second embodiments will be omitted. The third embodiment differs from the first and second embodiments in the eradication component. Specifically, the disinfecting component according to Embodiment 3 is sodium hypochlorite.

FIG. 13 is a front view of the disinfecting solution spraying device 1 according to the third embodiment. As shown in FIG. 13, in the third embodiment, the main body portion 121 of the support 12 has a sodium chloride inlet 123. Specifically, the insertion port 123 is a through hole penetrating the wall 121 b of the main body 121. When the user inserts the salt from the inlet 123, the salt falls into the storage unit 21. In addition, it is preferable that the salt injected | thrown-in is a lump which has a shape which is easy to inject | throw-in from the insertion port 123. FIG. For example, it is preferable that salt is rock salt or a salt pellet.

FIG. 14 is a cross-sectional view of the disinfecting solution spraying device 1 according to the third embodiment. In the present embodiment, the electrode pair 22 includes two platinum electrodes. As described with reference to FIG. 13, when the user inserts salt from the inlet 123, the salt falls into the storage unit 21 and dissolves in the water L. When the electrode pair 22 is energized in a state where sodium chloride is dissolved (dissolved) in the water L, a chlorine-based disinfecting component is generated. In detail, sodium hypochlorite water is produced | generated by supplying with current to the electrode pair 22 and performing electrolysis.

Then, with reference to FIG.7, FIG13 and FIG.14, the operation | movement of the disinfecting liquid spreading device 1 which concerns on Embodiment 3 is demonstrated. The user inputs a predetermined amount of sodium chloride from the inlet 123 before the start of the sterilization operation. Thereafter, the user depresses the sterilization button 31 of the operation unit 30 to cause the sterilization liquid dispersion apparatus 1 to execute the sterilization operation.

When the control device 40 receives from the operation unit 30 a signal instructing start of the sterilization operation, the control device 40 drives the adjustment valve 15 to inject a predetermined amount of raw water L into the storage unit 21 to dissolve the salt. In addition, as for the addition amount of salt, 0.1 weight% or more and 5 weight% or less are desirable.

When the raw water L of a predetermined amount is injected into the housing portion 21, the control device 40 energizes the electrode pair 22. As a result, electrolysis is performed in the housing portion 21. For example, a platinum-coated titanium electrode having a diameter of 1 mm and a length of 30 mm is used for each of the electrodes constituting the electrode pair 22, the distance between the electrodes is 3 mm, 1 g of sodium chloride is introduced into the

storage portion

21 and 100 ml of raw water L is added. When water is injected into the housing portion 21, in other words, when the addition amount of sodium chloride is 1% by weight, when a voltage of 5 V DC is applied to the electrode pair 22, a current of 150 mA or more and 170 mA or less flows between the electrodes to cause electrolysis. As the concentration of hypochlorous acid is increased, electrolysis of about one minute can produce about 10 ppm of sodium hypochlorite.

Specifically, hydrogen ions (H ⁺ ) are generated at the anode of the electrode pair 22. In addition, oxygen gas and chlorine gas are generated (Formula (1) and Formula (2)).
_{H 2 O → (1/2) O} 2 ↑ + 2H + + 2e - ··· formula (1)
2Cl → Cl ₂ + 2e ^- ··· formula (2)

Chlorine gas dissolves easily in water and changes to hypochlorous acid and hypochlorite ion in water as shown in the formulas (3) and (4).

Therefore, by performing electrolysis, disinfected water having an increased concentration of sodium hypochlorite can be generated. The concentration of sodium hypochlorite is preferably 5 ppm or more and less than 50 ppm. It is desirable that the effective chlorine concentration is 5 ppm or more because the lowest concentration at which the spores such as mold can be eliminated in the free state is 5 ppm. Moreover, it is desirable that the effective chlorine concentration is less than 50 ppm because, when the effective chlorine concentration is 50 ppm or more, it becomes easy to feel the chlorine smell from the mist of the disinfecting solution.

After energizing the electrode pair 22, the control device 40 generates an ultrasonic wave from the ultrasonic wave generation element 23 as described in the first embodiment. Further, the control device 40 drives the fan motor 112 to generate a wind that blows the mist of the disinfecting solution. As a result, the mist of the disinfecting solution is delivered from the delivery port 1a.

The third embodiment has been described above. According to the present embodiment, the hypochlorous acid water is atomized by the ultrasonic element, and the mist of the hypochlorous acid water is sent out from the outlet 1a through the guide surface 251 by the air blowing from the blower 11. Can. Therefore, as in the first embodiment, the disinfecting solution can be uniformly attached to the ceiling surface SS and the wall surface WS of the bathroom without being biased to a specific range.
