Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the following embodiments. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated. In addition, descriptions of overlapping portions may be omitted as appropriate.

[Embodiment 1]
FIG. 1 is a top view of a disinfecting liquid spraying device 1 according to Embodiment 1. FIG. As shown in FIG. 1, the disinfecting liquid spraying device 1 has a delivery port 1a. The sterilizing liquid spraying device 1 sends out a mist of the sterilizing liquid from the outlet 1a to spray the sterilizing liquid in the bathroom.

Further, as shown in FIG. 1 , the disinfecting liquid spraying device 1 includes a first unit 10 and a second unit 20 . In this embodiment, the delivery port 1a is a gap formed between the first unit 10 and the second unit 20. As shown in FIG.

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

The air blower 11 blows mist of the sterilizing liquid. In this embodiment, the blower device 11 includes a plurality of blades 111 and a fan motor 112 . A fan motor 112 rotates a plurality of blades 111 . Wind is generated by the rotation of the plurality of blades 111, and mist of the sterilizing liquid is blown. The blower device 11 is, for example, a DC fan. When the blower device 11 is a DC fan, it becomes easy to adjust the rotational speed of the fan motor 112 . In other words, it becomes easy to adjust the amount of air blown by the blower 11 .

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

The body portion 121 supports the blower device 11 . In this embodiment, the main body part 121 has a lid 121 a that supports the blower 11 . Preferably, the lid 121a supports the blower 11 at its center. By arranging the air blower 11 in the central portion of the lid 121a, it is possible to radially send out the mist of the sterilizing liquid from the sterilizing liquid spraying device 1 with the sterilizing liquid spraying device 1 as the center. In other words, it is possible to prevent the mist of the sterilizing liquid from being disproportionately delivered in a specific direction. Therefore, it is possible to sterilize a wider range by sending out the mist of the sterilizing liquid without bias in a specific direction.

A plurality of support members 122 protrude outward from the body portion 121 to support the second unit 20 . In the present embodiment, the body portion 121 has a rectangular shape in plan view, and the support members 122 protrude from the center of each side of the body portion 121 . The delivery port 1a is formed around the body portion 121. As shown in FIG. Specifically, a delivery port 1a is formed between a plurality of support members 122. As shown in FIG. In this embodiment, the delivery port 1a is L-shaped in plan view, and the disinfecting liquid spraying device 1 has four delivery ports 1a. The four delivery ports 1a can deliver the mist of the sterilizing liquid from substantially the entire periphery of the main body 121. As shown in FIG.

The supply pipe 13 supplies water to the second unit 20 . For example, the supply pipe 13 supplies tap water. A faucet 14 is provided on the supply pipe 13 . The faucet 14 can be opened and closed. When the faucet 14 is open, the supply pipe 13 can supply water. When the faucet 14 is closed, the supply of water through the supply pipe 13 is cut off. In this embodiment, the faucet 14 is arranged on the lid 121a. A regulating valve 15 is provided on the supply pipe 13 . The regulating valve 15 will be described later with reference to FIG.

Next, with reference to FIG. 2, the sterilizing liquid spraying device 1 will be further described. FIG. 2 is a cross-sectional view of the disinfecting liquid spraying device 1 according to the first embodiment. Specifically, FIG. 2 shows a cross section along line II-II of FIG. As shown in FIG. 2, the disinfecting liquid spraying 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.

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

Next, with reference to FIG. 2, the second unit 20 will be described. The second unit 20 includes a housing portion 21 , an electrode pair 22 , an ultrasonic wave generating element 23 , a water level sensor 24 and a guide member 25 . 1 is formed between the upper end of the guide member 25 and the main body portion 121 (wall portion 121b) of the support 12. As shown in FIG.

The containing portion 21 contains the solvent. The solvent is water L in this embodiment. The housing portion 21 has a box shape with an open top. In addition, 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 this embodiment, the electrode pair 22 is arranged on the floor surface of the housing portion 21 . A sterilization component is generated in the solvent (water L) by applying a voltage to the electrode pair 22 . As a result, a sterilization solution in which the solvent (water L) and the sterilization component are mixed is generated in the container 21 . In other words, the containing portion 21 contains the sterilizing liquid.

In this embodiment, the sterilizing component is silver ions. Specifically, each electrode 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 carried on part or all of the surface of the titanium metal. For example, the plate size of each electrode constituting the electrode pair 22 is 5 mm × 30 mm (thickness 0.3 mm), the distance between the electrodes is 3 mm, and 100 ml of tap water with a pH of 7.6 and a hardness of 45 mg / L is placed in the housing portion 21. When housed, when a voltage of DC 5V 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 generating element 23 applies ultrasonic vibrations to the sterilizing liquid to generate mist of the sterilizing liquid. Specifically, the ultrasonic wave generating element 23 is arranged on the floor surface of the housing portion 21 . In other words, the ultrasonic wave generating element 23 is immersed in the disinfecting liquid. The ultrasonic wave generating element 23 irradiates ultrasonic waves from inside the liquid toward the liquid surface. As a result, a fountain-like liquid column is generated on the liquid surface due to the sound pressure, and fog (sterilization liquid fog) is generated from the liquid column.

When the sterilizing liquid spraying device 1 sprays the sterilizing liquid, the water level (liquid level) of the sterilizing liquid contained in the housing portion 21 fluctuates. When generating fog by ultrasonic waves, it is necessary to adjust the position of the liquid surface (water level) so that the nodes of the ultrasonic waves are located on the liquid surface.

A water level sensor 24 detects the position of the liquid surface of the disinfecting liquid. The regulating valve 15 can be opened and closed. Water is supplied by the supply pipe 13 when the regulating valve 15 is open. When the regulating valve 15 is closed, the supply of water through the supply pipe 13 is cut off. The regulating valve 15 opens and closes based on the detection result of the water level sensor 24, and controls the supply of water through the supply pipe 13 so that the ultrasonic node is positioned at the liquid surface. The regulating valve 15 is, for example, an electromagnetic valve. The water level sensor 24 is, for example, a float switch. If the water level sensor 24 is a float switch, the water level sensor 24 detects whether the ultrasonic node is located at the liquid level. Specifically, the water level sensor 24 detects whether the water level of the sterilizing liquid is at a predetermined level. The predetermined water level is set according to the wavelength of the ultrasonic waves.

The guide member 25 has a guide surface 251 . Specifically, the inner surface of the guide member 25 forms the guide surface 251 . The guide surface 251 guides the mist of the sterilizing liquid blown by the air blower 11 to a predetermined surface so that the mist of the sterilizing liquid flows along the predetermined surface among the surfaces defining the bathroom. Specifically, in this embodiment, the blower 11 generates a wind directed toward the liquid surface of the sterilizing liquid. The mist of the sterilizing liquid is blown toward the guide surface 251 by the wind directed toward the liquid surface of the sterilizing liquid. As a result, the mist of the sterilizing liquid blown by the blower 11 is guided to a predetermined surface by the guide surface 251 .

In this embodiment, the guide surface 251 guides the mist of the disinfecting liquid to the ceiling surface SS of the bathroom. Specifically, the guide member 25 protrudes obliquely upward toward the outside from the upper end of the side wall of the housing portion 21 . Therefore, the guide surface 251 is an inclined surface, and is inclined so as to become closer to the ceiling surface SS of the bathroom as the distance from the housing portion 21 increases. As a result, mist of the sterilizing liquid is sent obliquely upward from the guide surface 251 and flows along the ceiling surface SS. In other words, the mist of the sterilizing liquid is delivered obliquely upward from the delivery port 1a. Alternatively, the sterilizing liquid mist is delivered from the guide surface 251 (delivery port 1a) from the horizontal direction to the upward direction. In some cases, the mist of the sterilizing liquid is horizontally delivered 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 sterilizing liquid may be sent out in the horizontal direction.

Next, referring to FIG. 3, the flow of the disinfectant liquid mist will be described. FIG. 3 is a diagram showing the flow of the disinfectant liquid fog according to the first embodiment of the present invention. Arrows D1 to D3 indicate directions in which the mist of the sterilizing liquid flows.

As shown in FIG. 3, the mist of the disinfecting liquid guided to the ceiling surface SS of the bathroom by the guide surface 251 flows along the ceiling surface SS. Further, the mist of the sterilizing liquid guided to the wall surface WS of the bathroom along the ceiling surface SS flows downward along the wall surface WS.

The disinfecting liquid spraying device 1 according to the present embodiment has been described above with reference to FIGS. 1 to 3. FIG. According to this embodiment, since the mist of the sterilizing liquid flows along the ceiling surface SS (an example of the predetermined surface) of the bathroom, a wider range of the ceiling surface SS can be sterilized. Furthermore, according to the present embodiment, it is possible to radially send the mist of the sterilizing liquid from the sterilizing liquid spraying device 1 centering on the sterilizing liquid spraying device 1 . Therefore, a wider range of the ceiling surface SS can be sterilized.

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

Further, according to this embodiment, the mist of the disinfecting liquid is sent 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 enters the bathroom from inhaling the mist of the disinfecting liquid while the disinfecting liquid is being sprayed. In addition, it is possible to prevent the disinfectant from adhering to people who enter the bathroom.

Next, with reference to FIGS. 4(a), 4(b), 5 and 6, the sterilizing liquid spraying device 1 according to this embodiment will be further described. FIG. 4(a) 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 Embodiment 1. FIG.

As shown in FIGS. 4A and 4B, the second unit 20 has a plurality of support holes 20a. In this embodiment, the guide member 25 has a plurality of support holes 20a. The support hole 20 a is a through hole that penetrates the guide member 25 . The plurality of support holes 20a are formed at positions corresponding to the plurality of support members 122 described with reference to FIG.

Moreover, in this embodiment, the guide surface 251 is annular. Since the guide surface 251 is annular, the mist of the disinfecting liquid can be sent radially from the disinfecting liquid spraying device 1 centering on the disinfecting liquid spraying device 1 . In other words, it is possible to prevent the mist of the sterilizing liquid from being disproportionately delivered in a specific direction. Therefore, it is possible to sterilize a wider range by sending out the mist of the sterilizing liquid without bias in a specific direction.

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

In this 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 made of an elastic material. For example, at least one of the guide member 25 and the support member 122 may be made of acrylic resin. Since 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 diagram showing a state in which the second unit 20 is separated from the first unit 10. As shown in FIG. In this embodiment, the support member 122 detachably supports the second unit 20 (the guide member 25). Therefore, the second unit 20 can be easily separated from the first unit 10 as shown in FIG. 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 air blower 11 draws in air from the outside and blows the air, so that the liquid (water L or sterilization liquid) contained in the container 21 contains dust and dirt from the outside. Easy to pick up dust. Moreover, when the water L is tap water, there is a possibility that scale of the tap water will accumulate in the storage portion 21 . Therefore, it is necessary to clean the inside of the second unit 20 regularly from a sanitary point of view. According to this embodiment, since the second unit 20 can be separated from the first unit 10, the inside of the second unit 20 can be washed easily.

Furthermore, when silver ions are used as the sterilizing component of the sterilizing liquid, the silver ions are reduced and aggregated to form a colloid. Since colloidal silver may cause malfunction of the ultrasonic wave generating element 23, it is necessary to periodically wash the inside of the housing 21 to remove the colloidal silver. According to this embodiment, since the second unit 20 can be separated from the first unit 10, the inside of the storage section 21 can be easily washed.

Moreover, in this embodiment, silver ions are eluted from the anode of the electrode pair 22 . Therefore, the size of the anode (electrode) becomes smaller as the disinfecting liquid spraying device 1 is used. Therefore, it is necessary to replace the electrode pair 22 periodically. In this embodiment, the electrode pair 22 is provided in the accommodation portion 21 . Also, the second unit 20 can be separated from the first unit 10 . Therefore, the electrode pair 22 can be easily replaced.

Both the guide member 25 and the support member 122 are preferably made of a material having elasticity. Since both the guide member 25 and the support member 122 have elasticity, the second unit 20 can be separated from the first unit 10 more easily. Moreover, 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 .

Next, with reference to FIG. 7, the disinfecting liquid spraying device 1 will be further described. FIG. 7 is a block diagram of the disinfecting liquid spraying device 1 according to Embodiment 1. As shown in FIG. As shown in FIG. 7, the disinfecting liquid spraying device 1 further includes an operation unit 30, a control device 40, and first to fourth power supply devices 41 to 44. As shown in FIG.

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

In this embodiment, the operation unit 30 includes a sterilization button 31 , a stop button 32 and a display 33 . Also, the operation unit 30 includes a processor, a semiconductor memory, and an interface circuit. The processor is, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The operation unit 30 includes, for example, a RAM (Random Access Memory) and a ROM (Read Only Memory) as semiconductor memories. The processor executes various processes according to a control program (computer program) stored in a semiconductor memory. The interface circuit executes communication between the operation unit 30 and the control device 40 .

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

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

A 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 liquid spraying device 1 is performing the sterilization operation. Further, for example, the display 33 displays the elapsed time from the start of the sterilization operation or the remaining time until the end of the sterilization operation.

The control device 40 controls the operation of the disinfecting liquid spraying device 1 . Specifically, the control device 40 includes a processor, a semiconductor memory, and an interface circuit. A processor is, for example, a CPU or an MPU. The control device 40 includes, for example, RAM and ROM as semiconductor memories. The processor executes various processes according to a control program (computer program) stored in a semiconductor memory. The interface circuit executes communication between the control device 40 and the operation section 30 . In the present embodiment, when the controller 40 receives a signal instructing the start of the sterilization operation from the operation unit 30, the control device 40 operates the first power supply device 41 to the fourth power supply device 44 so that the sterilization operation is executed. to control.

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

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

The third power supply 43 is controlled by the control device 40 to generate 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 that blows the mist of the sterilizing liquid. It is preferable that the control device 40 periodically change the number of rotations of the fan motor 112 to periodically change the amount of air blown by the blower 11 . By changing the amount of air blown by the air blower 11, the scattering distance of the mist of the disinfecting liquid can be changed, and the disinfecting liquid can be adhered more uniformly to the ceiling surface SS and the wall surface WS.

The fourth power supply 44 is controlled by the controller 40 to generate a voltage that drives the regulating valve 15 . Specifically, based on the output of the water level sensor 24, the control device 40 controls the fourth power supply device 44 so that the water level of the sterilizing liquid reaches a predetermined water level. Specifically, when the water level of the sterilizing liquid drops due to the sterilizing operation, the control device 40 opens the regulating valve 15 . As a result, as described with reference to FIG. 2, water is supplied from the supply pipe 13 to the storage portion 21 . Further, the control device 40 closes the regulating valve 15 when the water level of the sterilizing liquid rises to a predetermined water level.

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

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

After energizing the electrode pair 22, the control device 40 causes the ultrasonic wave generating element 23 to generate ultrasonic waves (step S2). Further, the control device 40 drives the fan motor 112 to generate a wind that blows the disinfectant liquid mist (step S2). As a result, the mist of the sterilizing liquid is delivered from the delivery port 1a described with reference to FIGS.

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

When the control device 40 determines that the water level of the sterilizing liquid is at the predetermined water level (Yes in step S3), it determines whether a predetermined period of time has elapsed since receiving the signal instructing the start of the sterilizing operation. (step S4).

On the other hand, when the control device 40 determines that the water level of the sterilizing liquid is not the predetermined level (No in step S3), it drives the regulating valve 15 so that the water level of the sterilizing liquid 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 section 21 to raise the water level of the sterilizing liquid to a predetermined water level.

When the water level of the sterilizing liquid rises to a predetermined water level, the control device 40 closes the regulating valve 15 and then energizes the electrode pair 22 so that the concentration of silver ions reaches a predetermined concentration (step S6). After energizing the electrode pair 22, the control device 40 determines whether or not a predetermined period has passed since receiving the signal instructing the start of the sterilization operation (step S4).

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

The flow of processing executed by the control device 40 has been described above with reference to FIGS. 7 and 8. FIG. According to the process shown in FIG. 8, the concentration of silver ions in the disinfecting liquid can be maintained at a predetermined level, and the disinfecting liquid can be sprayed in the bathroom.

Next, with reference to FIGS. 7 and 9, the flow of other processes executed by the control device 40 will be described. FIG. 9 is a flowchart showing another example of processing executed by the control device 40 according to the first embodiment. When the control device 40 receives a signal instructing the start of the sterilization operation from the operation unit 30, the processing shown in FIG. 9 is started. Differences from the processing shown in FIG. 8 will be described below.

As shown in FIG. 9, when the control device 40 determines that the water level of the disinfecting liquid is at a predetermined level (Yes in step S3), the first predetermined It is determined whether or not the period has passed (step S11).

Further, when the control device 40 drives the regulating valve 15 to return the water level of the sterilizing liquid to a predetermined water level (step S5), the second predetermined period elapses after receiving the signal instructing the start of the sterilizing operation. It is determined whether or not it has passed (step S12). The second predetermined period is a period shorter than the first predetermined period.

When the control device 40 determines that the second predetermined period has not elapsed (No in step S12), it energizes the electrode pair 22 so that the concentration of silver ions reaches a predetermined concentration (step S6). On the other hand, when the controller 40 determines that the second predetermined period has elapsed (Yes in step S12), the controller 40 does not energize the electrode pair 22 . 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 housing portion 21 .

In this embodiment, the second predetermined period is set so that the liquid stored in the storage section 21 returns from the sterilizing liquid to the normal water L before the first predetermined period elapses. Therefore, before the first predetermined period elapses, the ultrasonic generator 23 applies ultrasonic vibrations to the water L to generate water mist, and the air blower 11 blows the water L mist.

The flow of other processes executed by the control device 40 has been described above with reference to FIGS. 7 and 9. FIG. According to the process shown in FIG. 9, after the sterilizing liquid is attached to the ceiling surface SS and the wall surface WS, water is attached to the ceiling surface SS and the wall surface WS to maintain the sterilizing effect of silver ions for a long time. can be done. Specifically, silver colloid is precipitated when the disinfecting liquid dries. Silver colloid has a small sterilizing effect against fungi and general bacteria. Therefore, in order to maintain the disinfecting effect of the silver ions adhering to the ceiling surface SS and the wall surface WS for a long time, it is necessary to prevent drying of the disinfecting solution. On the other hand, according to the processing shown in FIG. 9, drying of the disinfecting liquid adhering to the ceiling surface SS and the wall surface WS can be prevented. Therefore, the sterilization effect of the silver ions adhering to the ceiling surface SS and the wall surface WS can be maintained for a long time.

Furthermore, when the disinfecting liquid dries and the colloidal silver precipitates, the ceiling surface SS and the wall surface WS are darkened by the colloidal silver, which deteriorates the appearance. On the other hand, according to the processing shown in FIG. 9, drying of the disinfecting liquid adhering to the ceiling surface SS and the wall surface WS can be prevented. Therefore, it is possible to suppress the occurrence of darkening.

In the process shown in FIG. 9, normal water was sprayed after spraying the disinfecting liquid, but normal water may be sprayed after a certain period of time has passed since the spraying of the disinfecting liquid is completed. In this case, even if the sterilizing solution dries and the silver colloid is precipitated, the silver colloid can be dissolved to generate silver ions. Moreover, even if darkening occurs, dissolving the silver colloid can make the darkening inconspicuous.

Next, the energization time of the electrode pair 22 will be described with reference to FIGS. 10(a) and 10(b). FIG. 10(a) is a graph showing changes in silver ion concentration over time. 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. Specifically, FIG. 10A shows the 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 storage section 21 and applying a voltage of DC 5 V 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. 10(a), the silver ion concentration reached 500 ppb in 3 minutes. In addition, the silver ion concentration reached 1000 ppb or more after 5 minutes of elapsed time.

In FIG. 10(b), the vertical axis indicates the sterilization rate, and the horizontal axis indicates the silver ion concentration. Further, in FIG. 10(b), the graph marked with x indicates the sterilization rate of Staphylococcus aureus, and the graph with black circles indicates the sterilization rate of black mold. As shown in FIG. 10(b), 90% or more of common bacteria (for example, Staphylococcus aureus) can be sterilized by silver ions at a concentration of 50 ppb or more and 100 ppb or less. Black mold (Cladosporium) can be sterilized by 90% or more with 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 eradicating general bacteria and fungi.

The first embodiment has been described above. According to Embodiment 1, it is possible to uniformly adhere the disinfecting liquid to the ceiling surface SS and the wall surface WS of the bathroom without being biased to a specific range.

Although the guide surface 251 is an inclined surface in this embodiment, the guide surface 251 may include a horizontal surface. For example, the guide surface 251 can include a horizontal surface parallel to the ceiling surface SS. In this case, the mist of the sterilizing liquid is sent horizontally from the guide surface 251 and flows along the ceiling surface SS.

In addition, in the present embodiment, the disinfecting liquid spraying device 1 has four L-shaped outlets 1a, but the number and shape of the outlets 1a are not particularly limited. FIG. 11(a) is a diagram showing a modification of the disinfecting liquid spraying device 1 according to the first embodiment.

As shown in FIG. 11(a), the disinfecting liquid spraying device 1 may have a plurality of circular delivery ports 1a. Specifically, in the disinfecting liquid spraying device 1 shown in FIG. 11( a ), a plurality of circular delivery ports 1 a are arranged along the circumferential direction around the main body 121 of the support 12 . Further, the support 12 includes a collar portion 124 that supports the guide member 25 (second unit 20) instead of the plurality of support members 122 described with reference to FIGS. A plurality of circular delivery ports 1 a are formed in the collar portion 124 . In addition, in the sterilizing liquid spraying device 1 shown in FIG. 11(a), the sterilizing liquid mist may be sent upward from the delivery port 1a. For example, if the delivery port 1a is far from the outer edge of the flange 124, mist of the disinfecting liquid may be delivered upward.

Further, in the present embodiment, the outer shape of the guide member 25 (second unit 20) is rectangular in plan view, but the outer shape of the guide member 25 (second unit 20) is not particularly limited. FIG. 11(b) is a diagram showing another modification of the disinfecting liquid spraying device 1 according to the first embodiment. As shown in FIG. 11(b), 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, the inner surface of the guide member 25 and the outer peripheral surface of the flange portion 124 of the support 12 may be formed with screw grooves corresponding to each other. That is, the guide member 25 may be supported by the flange portion 124 of the support 12 by rotating the second unit 20 .

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

[Embodiment 2]
Next, Embodiment 2 of the present invention will be described with reference to FIG. However, matters different from those of the first embodiment will be explained, and explanations of matters that are the same as those of the first embodiment will be omitted. Embodiment 2 differs from Embodiment 1 in the position of the electrode pair 22 .

FIG. 12 is a cross-sectional view of the disinfecting liquid spraying device 1 according to Embodiment 2. As shown in FIG. As shown in FIG. 12 , the second unit 20 includes a support member 26 connected to the inner surface of the housing portion 21 . Support member 26 supports 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 generating element 23 . By locating the electrode pair 22 directly above the ultrasonic wave generating element 23 , ultrasonic vibration can be applied to the sterilizing liquid between the two electrodes that constitute the electrode pair 22 .

The second embodiment has been described above. According to Embodiment 2, ultrasonic vibration can be applied to the sterilizing liquid between the two electrodes. Therefore, it is possible to prevent the colloidal silver from adhering to the electrodes by swinging the sterilizing liquid between the two electrodes.

[Embodiment 3]
Next, Embodiment 3 of the present invention will be described with reference to FIGS. 13 and 14. FIG. However, matters different from those of the first and second embodiments will be explained, and explanations of the same matters as those of the first and second embodiments will be omitted. Embodiment 3 differs from Embodiments 1 and 2 in the sterilization component. Specifically, the disinfecting component according to Embodiment 3 is sodium hypochlorite.

FIG. 13 is a front view of the disinfecting liquid spraying device 1 according to Embodiment 3. FIG. As shown in FIG. 13 , in Embodiment 3, the main body 121 of the support 12 has a salt inlet 123 . Specifically, the inlet 123 is a through hole penetrating through the wall portion 121 b of the body portion 121 . When the user puts in salt through the inlet 123 , the salt drops into the container 21 . It should be noted that the salt to be introduced is preferably a lump having a shape that is easy to be introduced from the inlet 123 . For example, salt is preferably rock salt or salt pellets.

FIG. 14 is a cross-sectional view of the disinfecting liquid spraying device 1 according to Embodiment 3. As shown in FIG. In this embodiment, electrode pair 22 includes two platinum electrodes. As described with reference to FIG. 13, when the user puts in salt through the inlet 123, the salt drops into the container 21 and dissolves in the water L. As shown in FIG. When the electrode pair 22 is energized while salt is dissolved (dissolved) in the water L, a chlorine-based sterilizing component is generated. Specifically, sodium hypochlorite water is generated by conducting electrolysis by energizing the electrode pair 22 .

Next, the operation of the disinfecting liquid spraying device 1 according to Embodiment 3 will be described with reference to FIGS. 7, 13 and 14. FIG. The user puts in a predetermined amount of salt from the inlet 123 before starting the sterilization operation. After that, the user presses the sterilization button 31 of the operation unit 30 to cause the sterilization liquid spraying device 1 to perform the sterilization operation.

When the controller 40 receives a signal instructing the start of the sterilization operation from the operation unit 30, the control device 40 drives the regulating valve 15 to inject a predetermined amount of raw water L into the storage unit 21 to dissolve the salt. The amount of salt added is desirably 0.1% by weight or more and 5% by weight or less.

The control device 40 energizes the electrode pair 22 when a predetermined amount of raw water L is poured into the storage portion 21 . As a result, electrolysis is performed within 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 electrode constituting the electrode pair 22, and the distance between the electrodes is set to 3 mm. When water is poured into the housing portion 21, in other words, when the amount of salt added is 1% by weight, when a voltage of DC 5V is applied to the electrode pair 22, a current of 150 mA or more and 170 mA or less flows between the electrodes and electrolysis occurs. As a result, the concentration of hypochlorous acid increases, and about 10 ppm of sodium hypochlorite can be generated by electrolysis for about 1 minute.

Specifically, hydrogen ions (H ⁺ ) are produced 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 easily dissolves in water, and changes into hypochlorous acid and hypochlorite ions in water as shown in formulas (3) and (4).

Therefore, by performing electrolysis, sterilized water with an increased concentration of sodium hypochlorite can be produced. It should be noted that the concentration of sodium hypochlorite is desirably 5 ppm or more and less than 50 ppm of available chlorine. The reason why the effective chlorine concentration is preferably 5 ppm or more is that the minimum concentration at which spore-forming bacteria such as mold can be sterilized in a free state is the effective chlorine concentration of 5 ppm. The reason why the effective chlorine concentration is preferably less than 50 ppm is that when the effective chlorine concentration is 50 ppm or more, the fog of the disinfecting liquid is likely to smell of chlorine.

After energizing the electrode pair 22, the control device 40 causes the ultrasonic wave generating element 23 to generate ultrasonic waves as described in the first embodiment. In addition, the control device 40 drives the fan motor 112 to generate a wind that blows the mist of the sterilizing liquid. As a result, a mist of the sterilizing liquid is delivered from the delivery port 1a.

The third embodiment has been described above. According to this embodiment, the hypochlorous acid water is atomized by the ultrasonic element, and the mist of the hypochlorous acid water is sent out from the delivery port 1a through the guide surface 251 by blowing air from the air blower 11. can be done. Therefore, similarly to the first embodiment, it is possible to uniformly adhere the sterilizing liquid to the ceiling surface SS and the wall surface WS of the bathroom without being biased to a specific range.

In this embodiment, salt is introduced through the inlet 123, but salt may be introduced through the delivery port 1a described in the first embodiment.

[Embodiment 4]
Next, Embodiment 4 of the present invention will be described with reference to FIG. However, matters different from those of Embodiments 1 to 3 will be explained, and explanations of matters that are the same as those of Embodiments 1 to 3 will be omitted. Embodiment 4 differs from Embodiments 1 to 3 in the configuration of the first unit 10 .

FIG. 15 is a cross-sectional view of the disinfecting liquid spraying device 1 according to Embodiment 4. As shown in FIG. As shown in FIG. 15 , the disinfecting liquid spraying device 1 according to this embodiment further includes a hollow member 51 and a mesh member 52 . More specifically, the first unit 10 further includes a hollow member 51 and a mesh member 52 .

The hollow member 51 is arranged above the ultrasonic wave generating element 23 . More specifically, the hollow member 51 is arranged directly above the ultrasonic wave generating element 23 and at a position higher than the liquid level of the water L (solvent), that is, the liquid level of the sterilizing liquid.

The hollow member 51 has a first opening 511 that communicates the inside and the outside of the hollow member 51 . The first opening 511 faces the ultrasonic wave generating element 23 . More specifically, the first opening 511 is arranged directly above the ultrasonic wave generating element 23 and at a position higher than the liquid level of the water L (solvent), that is, the liquid level of the sterilizing liquid.

The hollow member 51 of this embodiment is a cylindrical body extending in the vertical direction, and in addition to the first opening 511 , further has a second opening 512 that communicates the inside and the outside of the hollow member 51 . The second opening 512 faces the first opening 511 in the vertical direction.

The hollow member 51 has a diameter larger than the liquid column generated from the liquid surface of the liquid (water L or sterilizing liquid) contained in the containing portion 21 . Specifically, the diameter of the hollow member 51 is adjusted so that the mist generated from the surface of the liquid column can be flowed out of the hollow member 51 from the first opening 511 of the hollow member 51 by the wind generated by the blower 11. set. As described in the first embodiment, the liquid column is generated when the ultrasonic wave generating element 23 applies ultrasonic vibrations to the liquid (water L or sterilizing liquid).

In this embodiment, the support 12 supports the hollow member 51 . More specifically, lid 121 a supports hollow member 51 , and hollow member 51 extends from above lid 121 a to the inside of second unit 20 .

The mesh member 52 is arranged inside the hollow member 51 . Specifically, the mesh member 52 is arranged so that the height of the uppermost surface of the mesh member 52 from the liquid surface is lower than the maximum height of the liquid column. In this embodiment, the mesh-like member 52 has a convex shape protruding upward. The mesh member 52 is, for example, a metal mesh. A material of the metal mesh is, for example, stainless steel.

The blower device 11 is arranged above the mesh member 52 . The wind generated by the blower 11 flows toward the mesh member 52 . As a result, mist generated from the surface of the liquid column flows out of the hollow member 51 through the first opening 511 by the wind generated by the blower 11 .

In this embodiment, the blower device 11 is arranged inside the hollow member 51 . More specifically, the blower device 11 is arranged near the second opening 512 . In addition, the position where the air blower 11 is arranged is not particularly limited as long as the air can flow toward the mesh-like member 52 . However, in order to prevent the liquid column from colliding with the blower 11, the blower 11 is preferably arranged such that the height from the liquid surface is higher than the maximum height of the liquid column.

The disinfecting liquid spraying device 1 according to the present embodiment has been described above with reference to FIG. 15 . According to this embodiment, the liquid column generated from the liquid surface of the liquid (water L or sterilizing liquid) contained in the containing portion 21 can be contained inside the hollow member 51 . Moreover, the maximum height of the liquid column can be suppressed by the mesh member 52 . Therefore, it is possible to prevent the liquid (water L or the sterilizing liquid) from leaking out of the sterilizing liquid spraying device 1 .

Specifically, the height of the liquid column generated by ultrasonic vibration varies. Fluctuations in the height of the liquid column increase the vibration (amplitude) of the liquid surface. Specifically, the greater the variation in the height of the liquid column, the greater the vibration (amplitude) of the liquid surface. Therefore, depending on the fluctuation range of the height of the liquid column, there is a possibility that the liquid (water L or the sterilizing liquid) may leak out of the sterilizing liquid spraying device 1 from the delivery port 1a described with reference to FIG. . In contrast, according to the present embodiment, the mesh member 52 can suppress the maximum height of the liquid column. Therefore, it is possible to suppress the fluctuation range of the height of the liquid column and prevent the liquid (water L or the sterilizing liquid) from leaking out of the sterilizing liquid spraying device 1 .

Moreover, in this embodiment, the mesh member 52 is used to suppress the maximum height of the liquid column. Therefore, compared with the structure which uses a plate-shaped member and suppresses the maximum height of a liquid column, decline in atomization efficiency can be suppressed. That is, compared with the structure using a plate-shaped member, it becomes difficult to reduce the amount of fog generation. Specifically, when the maximum height of the liquid column is suppressed by the plate-like member, the shape of the liquid column may be deformed and the atomization efficiency may be reduced. On the other hand, when the maximum height of the liquid column is suppressed by the mesh-like member 52, the shape of the liquid column is less likely to collapse than when the plate-like member is used. Therefore, a decrease in atomization efficiency can be suppressed.

Moreover, the mesh-like member 52 of this embodiment has a convex shape protruding upward. Since the mesh-like member 52 has such a shape, the shape of the liquid column becomes difficult to collapse, and a decrease in atomization efficiency can be suppressed.

Next, the position of the uppermost surface of the mesh member 52 will be described. The height of the uppermost surface of the mesh member 52 from the liquid surface is not particularly limited as long as it is lower than the maximum height of the liquid column. However, if the height of the uppermost surface of the mesh-like member 52 from the liquid surface is lower than the standard height (average height) of the liquid column, the height of the liquid column is too restricted, and the atomization efficiency decreases. there's a possibility that. Therefore, the mesh-like member 52 is preferably arranged so that the height of the uppermost surface of the mesh-like member 52 from the liquid surface is higher than the standard height (average height) of the liquid column.

Next, the mesh pitch of the mesh member 52 will be described. The pitch of the mesh is not particularly limited as long as the liquid column can pass through the mesh-like member 52, but it is preferable that the pitch is such that the shape of the liquid column does not easily collapse. For example, the mesh pitch is 3 mm or more and 5 mm or less.

Although the shape of the hollow member 51 in the present embodiment is cylindrical, the shape of the hollow member 51 suppresses spillage of the water L (solvent) or the sterilizing liquid to the outside of the sterilizing liquid spraying device 1. It is not particularly limited as long as possible. For example, the hollow member 51 may have a shape in which a slit-shaped opening is formed in a part of the side wall of a cylindrical body.

Further, the hollow member 51 of the present embodiment extends from above the lid 121a to the inside of the second unit 20, but the length of the hollow member 51 is the height of the uppermost surface of the mesh member 52 from the liquid surface. There is no particular limitation as long as the mesh member 52 can be supported at a position where the height is lower than the maximum height of the liquid column.

In addition, although the blower 11 of the present embodiment is arranged inside the hollow member 51, the position of the blower 11 is not particularly limited as long as the air can flow toward the mesh member 52. For example, the blower 11 may be arranged above the hollow member 51 .
