  An aspect of the present invention generally relates to a sterilizing water spouting device and a bathroom unit for a bathroom washing place.

  For example, dirt such as soaps and shampoos used to clean the human body and reds (proteins, carbohydrates, fats, salts, etc.) generated from the human body adhere to the bathroom floor. A cleaning device for sterilizing bacteria caused by such dirt has been proposed. Patent Document 1 discloses a configuration in which disinfecting water containing hypochlorous acid or the like is discharged on a bathroom wash floor.

JP 2008-168230 A

  It is thought that the entire floor can be sterilized evenly by discharging a large amount of sterilized water over the entire bathroom floor. However, since the washing floor of a general bathroom has a drainage gradient, when a large amount of sterilized water is discharged, the sterilized water that reaches the washing floor tends to flow as a water film. For this reason, the sterilized water may flow to the drain before exhibiting a sufficient sterilizing effect. In this case, a large amount of sterilized water is required to sterilize the entire washroom floor without unevenness.

  Therefore, in order to sterilize the entire washing floor with a small amount of sterilizing water, it is conceivable to discharge the water in such a form that the sterilizing water tends to stay on the washing floor. Thereby, the time for the sterilized water to act on the bacteria on the washing floor can be lengthened. For example, in order to sterilize the washing floor with a small amount of sterilized water, it is suitable to discharge granular (mist-like) sterilized water having a small particle size.

  However, when using water containing hypochlorous acid as sterilized water, the concentration of hypochlorous acid in the sterilized water tends to decay over time, and this concentration decay is caused by the discharged sterilized water. There is a problem that the smaller the particle size, the more pronounced it becomes.

  DISCLOSURE OF THE INVENTION The present invention has been made on the basis of recognition of such a problem, and a sterilizing water spouting device for a bathroom washing place capable of efficiently sterilizing a washing place floor with a small amount of sterilizing water containing hypochlorous acid, and The object is to provide a bathroom unit.

According to this bathroom sterilization water spouting device, since the sterilized water containing hypochlorous acid is discharged in the form of mist (granular), the sterilized water is in a granular state on the washing floor (cleaning area). Can be attached. As a result, the sterilized water can be temporarily retained in the washing floor, and the amount of the sterilized water necessary for sterilizing the entire floor can be suppressed.
Here, the concentration of hypochlorous acid in the sterilized water grains has a property of decaying with time. And this density | concentration attenuation of hypochlorous acid becomes so remarkable that the particle size of the discharged disinfection water becomes small. For this reason, if the sterilized water adhering to the washing floor remains in a granular state, the concentration of hypochlorous acid is attenuated before the sterilizing water sufficiently acts on the bacteria on the washing floor, resulting in sufficient removal. Bacterial effect may not be obtained.
On the other hand, according to the sterilizing water spouting device for bathroom washing place, the sterilizing water is discharged to the part of the washing area until the particles of the sterilizing water attached to the part of the washing area are connected.

WHEREIN: In the said 1st process by which the said disinfecting water is discharged to the said one part washing | cleaning area | region, the said particle | grains connect and the drainage gradient of the said wash-room floor. If it will be in the state which flows with self-weight, it will be the disinfection water spouting device for bathroom washing places, performing the 2nd process.

  According to the sterilizing water spouting device for bathroom washroom, when the sterilizing water is discharged to the part of the washing area by the first step, the sterilizing water particles attached to the part of the washing area are drained. The second step is not executed until the second step is connected to such an extent that it flows under its own weight with respect to the gradient. Thereby, the particle | grains of the disinfecting water adhering to the washroom floor can be connected in a short time. By connecting the particles of the sterilized water in a short time, the specific surface area of the sterilized water can be reduced and the concentration attenuation of hypochlorous acid can be efficiently suppressed. Therefore, the washroom floor of the bathroom can be sterilized efficiently with a small amount of sterilized water containing hypochlorous acid.

The sterilizing water spouting device 100 is a device that is installed in a bathroom and sterilizes a bathroom floor.

First, with reference to Fig.2 (a) and FIG.2 (b), the bathroom (bathroom unit) in which the disinfection water discharging apparatus 100 of embodiment is installed is demonstrated.
FIG. 2A is a schematic perspective view of the bathroom 500.
FIG. 2B is a schematic perspective view in which the vicinity of the counter 530 in the bathroom 500 is enlarged.

  As illustrated in FIG. 2A, the bathroom 500 is surrounded by first to fourth walls 541 to 544 and a ceiling 545. The bathroom 500 has a bathtub 510, a washroom floor 520, and a counter 530. Furthermore, the bathroom 500 is appropriately provided with a mirror, a water tap, a shower hose, and the like.

  On the short side of the bathtub 510, a first wall 541 and a second wall 542 are provided facing each other. A fourth wall 544 is provided on the long side of the bathtub 510. Opposite to the fourth wall 544, a third wall 543 is provided on the washing floor 520 side.

  The washing floor 520 is provided with a drain outlet 521. In the example shown in FIG. 2, the drain outlet 521 is provided in the vicinity of the center in the direction connecting the first wall 541 and the second wall 542 at the edge of the wash floor 520 on the bathtub 510 side.

  The floor surface of the washroom floor 520 has a gentle downward slope toward the drain outlet 521 from the edge on the first wall 541 side, the edge on the second wall 542 side, and the edge on the third wall 543 side. Is provided as a drainage gradient.

  The counter 530, the mirror, the water tap and the shower hose are attached to the second wall 542, for example.

  The counter 530 is installed so as to be spaced upward from the floor surface of the washing floor 520. The counter 530 has a substantially rectangular shape that is long in the horizontal direction when viewed from above. The width in the horizontal direction of the counter 530 is equal to the width in the horizontal direction of the washing floor 520.

  At least a part of the sterilizing water spouting device 100 is provided below the counter 530. In the example of FIG. 2B, the sterilizing water spouting unit 10 of the sterilizing water spouting device 100 is provided at the lower part of the counter 530. The sterilizing water spouting unit 10 is disposed at a position separated from the washing floor 520. The sterilizing water spouting unit 10 is installed, for example, near the center of the counter 530 in the longitudinal direction. That is, the sterilizing water spouting unit 10 is installed in the vicinity of the center in the short side direction of the washing floor 520 (direction connecting the fourth wall 544 and the third wall 543). Thereby, it becomes easy to discharge the sterilized water to the whole washing place floor 520.

  The counter 530 includes a top plate 531, a front cover 532, and a lower cover 533 (shown in FIG. 1).

  FIG. 1 shows the counter 530 viewed from the side. For example, the sterilizing water spouting unit 10 is provided so as to protrude downward from the lower cover 533.

  A water supply pipe 51 and a hot water supply pipe 52 are provided outside the bathroom 500. The water supply pipe 51 is connected to a water pipe (not shown). Tap water is supplied from the water supply pipe 51 to the sterilizing water spouting device 100.

  As shown in FIG. 1, there are a stop cock 53, a solenoid valve 54, a pressure regulating valve 55, a check valve 56, and a sterilizer on the inside of the top plate 531, the front cover 532 and the lower cover 533 in the counter 530. A water generation unit 20, a motor 17, and a control unit 30 are provided.

  The stop cock 53 is connected to the water supply pipe 51. In the flow path between the water supply pipe 51 and the sterilized water spouting unit 10, the stop cock 53, the electromagnetic valve 54, the pressure regulating valve 55, the check valve 56, and the sterilized water generating unit 20 are connected in order from the upstream side. Has been.

  It should be noted that at least a part of the stop cock 53, the electromagnetic valve 54, the pressure regulating valve 55, the check valve 56, the sterilized water generation unit 20, the motor 17, and the control unit 30 are outside the counter 530 or outside the bathroom 500. It may be provided. For example, as illustrated in FIG. 2A, the control unit 30 may be provided outside the bathroom 500.

  Supply / cutoff of tap water to the downstream side is controlled by opening and closing the stop cock 53 and the electromagnetic valve 54. In response to the signal from the controller 30, the electromagnetic valve 54 performs an operation of opening the tap water flow path or an operation of closing the tap water flow path.

  The pressure regulating valve 55 controls the pressure of the supplied tap water. Thereby, the flow volume of the tap water supplied to the disinfection water production | generation part 20 can be adjusted. By adjusting the flow rate of tap water supplied to the sterilized water generating unit 20, the flow rate of sterilized water supplied to the sterilized water spouting unit 10 is adjusted. The flow rate may be adjusted using the electromagnetic valve 54.

The sterilized water generation unit 20 generates sterilized water from the supplied water.
FIG. 3 is a schematic cross-sectional view illustrating a specific example of the sterilized water generation unit of the embodiment.
For example, the sterilized water generator 20 is an electrolytic cell having an anode 21 and a cathode 23. The sterilized water generator 20 applies a voltage between the anode 21 and the cathode 23 to electrolyze the tap water flowing between the anode 21 and the cathode 23. Thereby, the sterilized water production | generation part 20 denatures tap water, and produces | generates sterilized water.

The sterilized water is water containing hypochlorous acid. Since tap water contains chloride ions, hypochlorous acid is generated by electrolyzing the chloride ions. As a result, the electrolyzed water changes to a liquid containing hypochlorous acid. In the present specification, “water containing hypochlorous acid (sanitized water)” includes at least one of hypochlorous acid (HClO) and hypochlorite ion (ClO ⁻ ).

In the embodiment, sterilized water containing hypochlorous acid and sterilized water containing metal ions may be used in combination. The sterilized water containing metal ions and the like includes, for example, metal ions such as silver ions, copper ions, and zinc ions, and ozone. For example, when tap water is electrolyzed, acid (H ⁺ ) is consumed at the cathode, and the pH increases near the cathode. That is, alkaline water is generated in the vicinity of the cathode. On the other hand, alkali (OH ⁻ ) is consumed at the anode, and the pH is lowered in the vicinity of the anode. That is, acidic water is generated in the vicinity of the anode. Metal ions of the electrode material are released from the anode to generate sterilized water. By changing the flow rate in the sterilized water generation unit 20, the concentration of components contained in the sterilized water can be controlled. The sterilized water generation unit 20 is not limited to the electrolytic cell.

  The sterilized water generated in the sterilized water generating unit 20 is supplied to the sterilized water spouting unit 10 and discharged from the sterilized water spouting unit 10 onto the washing floor 520. The washing floor 520 is sterilized by this sterilizing water.

  The disinfecting water discharge unit 10 has a nozzle. As shown in FIG. 1, in this example, the sterilizing water spouting unit 10 is provided with a first nozzle 11, a second nozzle 12, and a water storage unit 13. The water storage unit 13 has, for example, a cylindrical shape, and can temporarily store the sterilized water supplied from the sterilized water generation unit 20 in the internal space. The first nozzle 11 and the second nozzle 12 are provided on the side surface of the water storage unit 13. Each nozzle has a water outlet provided at the tip of the nozzle, and this water outlet makes the sterilized water stored in the water storage section 13 into mist-like (mist-like) particles and discharges them to the washing floor 520. .

  The mist-like particles refer to water droplets having such a diameter that they can stay on the washing floor 520 by their own weight with respect to the drainage gradient when attached to the washing floor 520. Mist-like grains adhere independently to the washroom floor. The drainage gradient is, for example, about 1 ° to 3 °. The diameter of the mist-shaped water droplet is, for example, about 200 micrometers (μm) or more and 500 μm or less. Moreover, the diameter of the water droplet discharged from the disinfecting water spouting unit 10 generally has a certain range. Here, the Sauter average particle diameter (= total particle volume / total particle surface area) is used as the diameter of the water droplets.

  The first nozzle 11 is provided above the second nozzle 12 in the vertical direction. The second nozzle 12 is inclined downward with respect to the horizontal direction, and the first nozzle 11 is inclined upward with respect to the horizontal direction. For example, the first nozzle 11 is a distant nozzle that covers a range far from the disinfecting water spouting unit 10 in the washing floor 520, and the second nozzle 12 is from the disinfecting water spouting unit 10 in the washing floor 520. It is a nozzle for the vicinity that takes charge of a close range. When viewed from above, the direction in which the sterilized water is discharged from the second nozzle 12 is along the direction in which the sterilized water is discharged from the first nozzle 11.

  In addition, the structure of the disinfection water discharging part 10 of embodiment is not restricted above. For example, you may change suitably the number of nozzles, the angle of the nozzle with respect to a horizontal direction, etc. In the embodiment, the sterilizing water spouting unit 10 only needs to be able to discharge sterilized water onto the washing floor 520 in a mist form.

  The sterilizing water spouting unit 10 can be rotated or slid by a motor 17, for example. The motor 17 is, for example, a stepping motor. As will be described later, the motor 17 rotates the sterilizing water spouting unit 10 around a rotation axis (for example, a vertical axis) to change the direction in which the sterilizing water is discharged. Can do. The first nozzle 11 and the second nozzle 12 can rotate together.

  The control unit 30 is electrically connected to the electromagnetic valve 54, the sterilized water generation unit 20, and the motor 17. The control unit 30 can control the mode of discharging the sterilized water (water discharge method, how to sprinkle) by controlling the operation of the electromagnetic valve 54, the sterilized water generation unit 20, and the motor 17.

  For example, the electromagnetic valve 54 opens and closes the tap water flow path based on a signal from the control unit 30. Thereby, the flow volume of the tap water supplied downstream is controlled. Further, the sterilized water generation unit 20 switches the electrolytic cell ON / OFF based on a signal from the control unit 30. Based on the signal transmitted from the control unit 30 to the motor 17, the sterilizing water spouting unit 10 changes the rotation angle and the rotation speed. Thus, the control unit 30 controls the concentration of the sterilized water, the instantaneous flow rate of the sterilized water to be discharged, the total amount of the sterilized water to be discharged, the operation of the sterilized water spouting unit 10, and the discharge direction of the sterilized water. Etc. can be controlled.

  As illustrated in FIG. 2A, the operation unit 35 electrically connected to the control unit 30 is provided inside the bathroom 500 or outside the bathroom 500. The user of the sterilizing water spouting device 100 can operate the operation of the sterilizing water spouting device 100 using the operation unit 35.

Next, with reference to Fig.4 (a)-FIG.5 (c), the discharge operation of the disinfecting water of embodiment is demonstrated.
FIG. 4A and FIG. 4B are schematic plan views of the washing floor 520 as viewed from above. As shown in FIG. 4A, the washing floor 520 has a rectangular shape with four edges 520a to 520d as viewed from above. The drain port 521 is provided on the edge portion 520d side. The edge portion 520d and the edge portion 520a opposite to the edge portion 520d extend in the longitudinal direction of the washing floor 520. The counter 530 and the sterilized water spouting unit 10 are provided on the edge 520b side. The edge portion 520b and the edge portion 520c opposite to the edge portion 520b extend in the short direction of the washing floor 520.

  The floor surface of the washroom floor 520 is provided with a drain slope that slopes downward from the edge 520a, the edge 520b, and the edge 520c toward the drain port 521. In FIG. 4A, the arrow end point (arrowhead) side is the low gradient side.

  As shown in FIG. 4B, the sterilized water is discharged from the nozzle (sterilized water spouting unit 10), for example, in the water discharge direction A. The sterilized water discharged from the nozzle has, for example, a conical expanse. In the top view of FIG. 4B (when viewed along the vertical direction), the sterilized water is discharged in the form of a mist with a fan or a triangular expanse 201. In this example, the water discharge direction is defined as a direction that bisects the center angle of the spread.

  Thus, in a certain state (a state in which the water discharge direction is constant), the nozzle discharges sterilized water to a part of the washing floor 520. If the opening diameter of the water outlet of the nozzle is reduced, the sterilized water can be discharged far away, but the discharged range becomes narrow.

  Here, as already described, the motor 17 is driven by the control unit 30, and the nozzle can rotate around the rotation shaft 10a. The water discharge direction can be changed by the rotation of the nozzle. As described above, the control unit 30 performs control to change the cleaning region in which the sterilized water is discharged by moving the nozzle. Thereby, disinfecting water can be sprayed on substantially the entire surface of the washroom floor 520. The nozzle may be configured to reciprocate along the longitudinal direction of the counter 530.

Fig.5 (a)-FIG.5 (c) are typical top views which illustrate the washing-room floor where the disinfecting water was discharged.
These show a part of the washing floor 520 (region R) in an enlarged manner. The region R is a part of a cleaning region (region where sterilized water is sprayed) when the nozzle is discharging water in a certain direction. For example, as shown in FIG. 4 (b), region R, the nozzle is part contained in the cleaning region R _B in a state of discharging a sterilizing water toward the water discharge direction B.

  As shown in FIG. 5A, convex portions 551 and grooves 552 (concave portions) are formed on the surface of the washing floor 520. The convex portion 551 has a function of preventing slipping. Water droplets adhering to the washing floor 520 flow into the groove 552 and flow to the drain outlet.

For example, a portion lower than the average height of the washing floor 520 (a height obtained by averaging unevenness excluding components due to drainage gradient) can be regarded as a groove (concave portion), and a high portion can be regarded as a convex portion. The depth of the groove 552 is, for example, about 0.5 millimeter (mm) or more and 1 mm or less. For example, the width of the groove 552 is about 0.6 mm or more and 1.5 mm or less. For example, the ratio of the groove area per unit area in the top view is about 80% to 90%.
Note that the depth of the groove 552 is a difference between the highest position of the convex portion 551 and the lowest position of the groove 552. In addition, the wash floor 520 may be provided with a plurality of types of protrusions having different heights and a plurality of types of grooves having different depths. The size of the groove 552 (the size of the convex portion) is not limited to the above. Further, the shape and pattern of the groove 552 are not limited to those shown in the figure. For example, the groove 552 may have a curved pattern instead of a linear shape, and has a wider width than the width of the convex portion 551. You may have.

  FIG. 5A illustrates an initial state in which the sterilized water starts to be discharged into the region R. Since the sterilized water is discharged from the nozzle in the form of mist as described above, mist particles 15 (water droplets) having a small diameter adhere to the washing floor 520.

  The sterilizing water spouting device 100 according to the embodiment spreads such a mist-like sterilizing water having a small diameter on the region R. FIG.5 (b) shows the state from which the sterilization water was further discharged from the state of Fig.5 (a), and FIG.5 (c) showed the further sterilization water being discharged from the state of FIG.5 (b). Indicates the state. In this way, when the mist-like sterilized water is piled up, the plurality of particles 15 are connected to each other to form a water droplet 16 having a large diameter, and flows into the groove 552.

  When the sterilizing water spouting device 100 discharges the sterilizing water to the extent that the grains 15 are connected on the region R, the sterilizing water discharging device 100 stops the discharge of the sterilizing water to the region R by changing the water discharging direction by the rotation of the nozzle. Disinfecting water is discharged around the region R. That is, in the embodiment, the control unit 30 discharges sterilized water to this region until the sterilized water particles attached to a part of the cleaning region are connected, and after the particles are connected, The nozzle is controlled to discharge sterilized water to the area.

  In addition, the state in which the sterilized water particles are “connected” in a certain cleaning region means, for example, a state in which the occupancy rate Ro1 of the water droplets in the groove 552 of the cleaning region is 80% or more. In the top view, when the area of the groove in the cleaning region is A1, and the area of the groove in the cleaning region where the sterilized water is attached is A2, the occupation rate Ro1 is Ro1 (%) = A2 / A1. Calculated by x100. In addition, the washing | cleaning area | region used by calculation of occupation rate Ro1 is an area | region where sterilization water is poured in a certain water discharge direction, or its part. For example, the occupation ratio Ro1 can be calculated for an area of about 5 cm × 5 cm or more.

  This “connected” state is a state in which the water droplets of the sterilized water on the washing floor 520 become large and the water droplets flow along the drainage gradient by their own weight.

  Considering that the disinfecting water does not easily reach the position far from the nozzle, the occupation ratio Ro1 is 80% even in the region including the vicinity of the edge 520c farthest from the counter (for example, the region R shown in FIG. 4B). The operation of the nozzle is controlled as described above. In addition, the nozzle may stop moving (rotating) during the period from when the sterilized water starts to be discharged to a part of the cleaning area until the sterilized water particles are connected on this area. It may move slowly.

  For example, water droplets adhering to the washing floor have a higher retention property as the diameter is smaller. If the diameter of the water droplet becomes too large, the water droplet forms a water film. Then, the sterilized water easily flows to the drain outlet due to the drainage gradient of the washroom floor. In contrast, in the embodiment, mist-like sterilized water is discharged onto the washing floor. Since such mist-like sterilized water reaches the washing floor as small particles, it tends to stay on the washing floor. By discharging the sterilized water in a highly retentive form, the time for the sterilized water to act on the bacteria on the washing floor can be secured. In addition, the amount of sterilized water that flows to the drain outlet before it acts on the bacteria and is wasted can be suppressed. Therefore, it is possible to suppress the amount of sterilized water necessary for sterilizing the entire washing floor.

  The concentration of hypochlorous acid in the sterilized water grains has the property of decaying over time. And this density | concentration attenuation of hypochlorous acid becomes so remarkable that the particle size of the discharged disinfection water becomes small. One possible reason for this is that, for example, the smaller the particle size, the larger the surface area per unit volume of the sterilized water. For example, as the surface area of the sterilized water grains increases, the contact between the outside such as the surrounding air and the sterilized water grains increases. For this reason, if the sterilized water adhering to the washing floor remains in a granular state, the concentration of hypochlorous acid is attenuated before the sterilizing water sufficiently acts on the bacteria on the washing floor, resulting in sufficient removal. Bacterial effect may not be obtained.

  In contrast, in the embodiment, the sterilized water is discharged to the cleaning area until the sterilized water particles attached to a part of the cleaning area are connected. For example, mist-like sterilized water is layered (continuously) in a certain area on the washing floor until the sterilized water particles are connected and enlarged. By connecting the sterilized water particles in this way, the surface area per unit volume of the sterilized water adhering to the washing floor can be reduced, and the concentration attenuation of hypochlorous acid can be suppressed. Discharge the sterilized water in the form of a mist to ensure retention, while reducing the concentration of hypochlorous acid by reducing the surface area, so a small amount of sterilized water containing hypochlorous acid can be used in the bathroom. The washroom floor can be sterilized efficiently.

Fig.6 (a) and FIG.6 (b) are graphs explaining the relationship between the discharging method of the disinfecting water containing hypochlorous acid, and the disinfection effect.
A method of “spouting large particles continuously” indicated by a dotted line, a method of “spouting small particles intermittently” indicated by a one-dot chain line, and a method of “spouting small particles continuously” indicated by a solid line Are comparing. The method of “spouting small particles continuously” indicated by a solid line corresponds to discharging the sterilized water according to the embodiment. In this comparison, the cleaning areas in each water discharge method are the same. Further, the total water discharge amount per unit area in each water discharge method is assumed to be equal to each other.

  FIG. 6A shows a temporal change in the concentration of hypochlorous acid in the sterilized water discharged onto the cleaning region. FIG. 6B shows the retention of the sterilized water on the cleaning region and the degree of suppression of the attenuation of hypochlorous acid concentration in the sterilized water discharged on the cleaning region in each water discharge method.

  In the method of “spouting large particles continuously”, sterilized water particles larger than mist-like particles are continuously discharged to the cleaning region. Large sterilized water particles have a small surface area, so the concentration of hypochlorous acid is not easily attenuated. On the other hand, large sterilized water particles have relatively low retention and are drained in a short time when discharged to a washing floor having a drainage gradient. For example, as shown in FIG. 6A, the sterilized water discharged during the period P1 is drained by the time T1. For this reason, there is a concern that the time for which the sterilized water acts on the bacterium is short and a sufficient sterilizing effect cannot be obtained.

  In the method of “discharging small particles intermittently”, the mist-like sterilized water particles are intermittently discharged in several times. For example, water discharge is performed in the periods P21, P22, and P23 shown in FIG. Water discharge in each period ends before the sterilized water particles adhering to the cleaning region are connected. The mist-like sterilized water particles have high retention, but the specific surface area is large, so that the concentration of hypochlorous acid is significantly reduced. For this reason, there is a concern that a sufficient disinfection effect cannot be obtained.

  In the method of “spouting small particles continuously”, water droplets of mist-like sterilized water are continuously discharged. For example, water discharge is performed in the period P3 shown in FIG. By discharging water continuously, the sterilized water particles adhering to the cleaning region are connected and drained, for example, at time T4. In this water discharge method, the sterilized water is not drained for a relatively long time, and the concentration decays slowly. Thereby, the concentration attenuation | damping of hypochlorous acid can be suppressed, ensuring a retention property, and the washroom floor of a bathroom can be disinfected efficiently with a small amount of disinfecting water.

  Next, with reference to Fig.7 (a)-FIG.7 (c), the specific example of the washing process of the washing-room floor using the disinfecting water by embodiment is demonstrated.

  FIG. 7A is a timing chart of turning on / off the water discharged from the sterilized water. Bactericidal water is discharged from the water outlet of the nozzles (nozzle 11 and nozzle 12) during the ON period. Bactericidal water is not discharged during the off period.

  FIG. 7B is a timing chart of the movement of the nozzles (nozzle 11 and nozzle 12). The stop of the movement of the nozzle (first step) and the rotational movement of the nozzle (second step) are alternately repeated.

  As described above, the control unit 30 performs the first step of discharging the sterilizing water from the nozzle in a state where the movement of the nozzle is stopped, and the first step of moving the nozzle so as to change the cleaning region where the sterilizing water is discharged. Two steps are performed alternately. In the first step, the sterilized water is discharged to a part of the washing area of the washing floor 520, and the sterilized water particles are connected to the part of the washing area.

  FIG. 7C is a schematic plan view illustrating the state of the washing floor 520 at each time ((1) to (15)) illustrated in FIG. In this example, the washing floor 520 is divided into a plurality of areas (cleaning areas R1 to R5) for cleaning. In the embodiment, how to select a plurality of cleaning regions (size, number, etc.) is arbitrary. In the schematic plan view of the washing place floor 520 at each time ((1) to (15)), the hatching density (color density) represents the amount of adhering sterilized water. The darker the color region, the more sanitized water is attached, and the lighter the color region, the less sanitized water is attached.

  Bactericidal water is discharged into the cleaning region R1 by the first step in the period S1. The first step is continued until the sterilized water particles attached to the cleaning region R1 are connected. After the sterilized water particles are connected, the second step is executed, and the region where the sterilized water is discharged is changed from the cleaning region R1 to the cleaning region R2.

  Subsequently, sterilized water is discharged into the cleaning region R2 by the first step during the period S2. The first step is continued until the sterilized water particles attached to the washing region R2 are connected. After the sterilized water particles are connected, the second step is executed, and the region where the sterilized water is discharged is changed from the cleaning region R2 to the cleaning region R3.

  Thereafter, the first step and the second step are similarly repeated, so that the sterilized water is sequentially discharged to the cleaning regions R3, R4, and R5. As a result, the entire washing floor 520 is washed.

  As described above, in this specific example, the first step and the second step are performed alternately. The first step is continued until, for example, the occupation ratio Ro1 of the water droplets of the sterilized water in the groove of the cleaning region R1 is 80% or more and the water droplets flow along the drainage gradient under their own weight. Until then, the second step, that is, the change of the water discharge direction is not performed. Thereby, in a state where the movement of the nozzle is stopped, mist-like sterilized water is piled on a part of the cleaning region. For this reason, the particle | grains of the disinfecting water adhering to the washroom floor can be connected in a short time. Hydration of hypochlorous acid can be efficiently suppressed by connecting the sterilized water grains in a short time.

  Further, as already described, when the diameter of water droplets attached to the washing floor 520 increases, the water droplets form a water film. Then, the sterilized water easily flows to the drain port 521 due to the drainage gradient of the washing floor 520. That is, if too much sterilized water is discharged to the same part of the washing floor, the sterilized water will flow to the drain before it exhibits a sufficient sterilizing effect.

  Therefore, in the embodiment, it is desirable to execute the second step before the entire cleaning region is covered with the water film of the sterilized water in the first step. For example, in the first step of discharging the sterilized water to a part of the cleaning region (for example, any one of the cleaning regions R1 to R4), the next second step in a state where the entire cleaning region is not covered with the water film. Execute. Specifically, in the first step of discharging the sterilized water to a part of the cleaning region (for example, any one of the cleaning regions R1 to R4), the occupancy rate Ro2 of the sterilizing water in the cleaning region is less than 100%. In the state, the second step is executed. As a result, the concentration of hypochlorous acid in the sterilized water is suppressed and the sterilized water adhering to the washing floor is prevented from flowing to the drain before it exhibits a sufficient sterilizing effect. Can do.

  Note that the occupation ratio Ro2 (%) in a certain cleaning region is represented by Ro2 (%) = A3 when the area of the cleaning region is A3 and the area of the cleaning region to which the sterilized water is attached is A4. It can be calculated by A4 / A3 × 100.

  Further, as shown in FIG. 7A, it is desirable that the sterilized water is continuously discharged also in the second step. Moreover, it is desirable that the flow rate of the sterilized water (amount of water discharged per unit time) is constant. As already described, in the sterilizing water spouting device 100 according to the present embodiment, sterilizing water containing hypochlorous acid is generated by the sterilizing water generating unit 20. Here, stopping the water discharge every time the second step is executed means that the sterilized water generating unit 20 is turned off every time the second step is executed. For this reason, if water discharge is stopped when performing a 2nd process, the density | concentration of hypochlorous acid in disinfection water will become difficult to stabilize. Even during the second step, the sterilized water is continuously discharged, so that water discharge can be performed in a state where the concentration of hypochlorous acid is stable.

  In addition, the time (length) of the first step for each cleaning region is desirably adjusted as appropriate depending on the distance from the nozzle to the end of the cleaning region, the magnitude and direction of the drainage gradient in the cleaning region, and the like. . For example, the first process time (period S3) for the cleaning region R3 may be longer than the first process time (period S1) for the cleaning region R1.

FIG. 8 is a flowchart illustrating the operation of the sterilizing water spouting device according to the embodiment.
When starting the operation, the control unit 30 moves the nozzle position to a predetermined position (initial position), for example, and executes the first step on a part of the cleaning region (for example, the cleaning region R1) (step S101). ). Then, the control part 30 performs a 2nd process in the state by which discharge of disinfecting water was continued (step S102), and changes a washing | cleaning area | region. Subsequently, the control unit 30 executes the first process on the changed cleaning region (for example, the cleaning region R2) (step S103).

Thereafter, when there is still a washing area where the sterilizing water is not discharged on the washing floor 520 (step S104: N), the control unit 30 repeats steps S102 and S103 again. That is, the cleaning region is changed by the second step, and the first step is performed on the changed cleaning region (for example, the cleaning region R3).
Thus, the 1st process and the 2nd process are repeated, and disinfection water is discharged to the whole washing-room floor (Step S104: Y).

  In this example, steps S101 to S104 are executed a predetermined number of times. In other words, the first step and the second step are alternately executed, and the step of discharging the sterilized water to the entire washing place floor 520 is executed a plurality of times. The predetermined number of times may be arbitrary.

  When the step of discharging the sterilizing water to the entire washing floor in steps S101 to S104 has not been executed a predetermined number of times (step S105: N), has the control unit 30 passed a predetermined time (step S106: Y)? ) And return to step S101 again to discharge the sterilized water. When the step of discharging the sterilized water to the entire washing floor is performed a predetermined number of times (step S105: Y), the process is terminated.

  Note that the predetermined time in step S106 is determined based on, for example, the time during which the sterilized water is discharged to the drain outlet in a part of the cleaning region (for example, the cleaning region R1) where the sterilized water is first discharged. After this predetermined time has elapsed from the start of the immediately preceding step S101, step S101 is started again.

  If a large amount of sterilized water is discharged onto the washing floor 520 at a time, the sterilized water may flow to the drain before the sufficient sterilizing effect is exhibited, and the sterilized water may be wasted. is there. Therefore, when the same amount of sterilized water is sprayed on the washing floor 520, it may be more efficient to divide it into multiple times. In the case of performing water discharge a plurality of times, by performing water discharge again after the sterilized water is drained, it is possible to suppress the sterilized water from flowing while forming a water film.

  As described above, the step of alternately performing the first step and the second step as shown in FIG. 7 and discharging the sterilized water to the entire washing floor 520 is performed at predetermined time intervals. Run multiple times. Thereby, the time which sanitization water acts on a microbe can be lengthened with as little sanitizing water as possible. The washing floor can be sterilized efficiently with a small amount of sterilized water.
