  Sealed water is formed inside the drainage port. The line (sealing water line) where the water surface of the water seal and the drainage trap forming the water seal contact (adhesion water line), dirt such as sebum which tends to float comes in contact with or adheres to the water surface, and bacteria are easily propagated using it as a nutrient source. In addition, the sealing water line is a site where water, nutrition, and air necessary for the growth of mold and fungus are present. Therefore, darkening tends to occur in the sealing water line.

  The applicant paid attention to this problem, and wanted to make bactericidal water act on a sealing water line formed inside the drainage port to suppress the occurrence of darkening.

  However, as described above, for example, when electrolyzed water such as hypochlorous acid water is used as sterilizing water, the electrolyzed water is sterilized when it comes in contact with bacteria and returns to water, so it flows in from the opening of the drainage port Before the electrolyzed water reaches the sealing water line, the concentration of the germicidal component of the electrolyzed water decreases. Therefore, the subject that the generation | occurrence | production of darkening in a sealing water line could not be suppressed appropriately occurred.

  An object of this invention is to provide the bathroom which can suppress generation | occurrence | production of darkening in a sealing water line.

The bathroom according to the first aspect of the present invention has a bath, a drainage plug provided in the bathtub, a drainage trap installed below a drainage port formed in the washing floor, and a sterilizing action toward the drainage trap An electrolyzed water discharge apparatus capable of discharging electrolyzed water, a control unit for executing control to discharge electrolyzed water upon receiving an electrolyzed water discharge execution command, and an operation for transmitting the execution command to the control unit by a user's operation The drainage trap is divided into two chambers, an inflow chamber and an outflow chamber, by a shielding member provided vertically from the top surface, and the drainage trap is disposed on the top surface of the inflow chamber. An opening for washing floor floor drainage inflow is provided, a communication portion between the inflow chamber and the outflow chamber is provided in a portion submerged in sealing water between the shielding member and the bottom of the main body, and an outflow port is provided in the outflow chamber. , Bathtub drainage inflow of bathtub drainage into the side of the inflow chamber And the bathtub drainage collides with the shielding member to generate an eddy current in the inflow chamber, and the control unit is configured to perform electrolysis until a predetermined time elapses after receiving the execution command. It is characterized in that control is performed so as to discharge the electrolyzed water after the predetermined time has elapsed without discharging the water.
According to the first aspect of the invention, after the user completes the use of the bathroom such as bathing, the user opens the drainage tap of the bathtub and discharges the electrolyzed water until the predetermined time elapses when the user operates the operation unit. Instead, the electrolyzed water is discharged after the predetermined time has elapsed.
When the drainage tap of the bathtub is opened, the bathtub drainage collides with the shielding member to generate an eddy current in the inflow chamber, and the eddy current generates a centrifugal force in the sealing water, and temporarily the drainage trap and the sealing water The water level of the sealing water line that the Thereby, sebum, hair and the like attached to the inner wall inside the drainage port above the actual sealing water line can be washed away.
Therefore, it is possible to suppress a decrease in the concentration of the bactericidal component of electrolyzed water due to contact with sebum attached to the inner wall inside the drainage port before reaching the original sealing water line where darkening is likely to occur. That is, the electrolyzed water can be made to flow into the sealing water line inside the drainage port without reducing the concentration of the germicidal component. Therefore, even when electrolyzed water is used as disinfecting water, the generation of darkening in the sealing water line can be appropriately suppressed.
A second invention according to the first invention is characterized in that the operation unit transmits the execution command to the control unit by the operation of the user and opens the drainage plug of the bathtub. .
According to the second aspect of the invention, the electrolytic water can be made to flow toward the drain after the above-mentioned swirling flow is used to ensure that sebum and hair and the like attached to the inner wall inside the outlet above the sealing water line are washed away reliably. it can. Thereby, the electrolyzed water which suppressed the fall of the bactericidal component density | concentration can be reliably made to flow in a sealing water line.
According to a third invention, in the first or second invention, the predetermined time is a time equal to or more than 300 seconds which is a time equivalent to a bathtub water discharge equivalent time which is assumed to be a time from the start of discharge of the bath water to the completion of discharge. It is characterized by
According to the third aspect of the invention, the drainage trap is completed after the bath water has been completely drained, that is, after the temporary rise of the water level due to the generation of the vortex in the drainage trap (after the vortex has disappeared). Electrolyzed water can flow into the inside. Thereby, the waste of the electrolyzed water discharged | emitted with a eddy current can be eliminated and electrolyzed water can be reliably made to flow in the original sealing water line.
According to a fourth invention, in any one of the first to third inventions, tap water which is not electrolyzed water is discharged toward the drainage port until the predetermined time passes, and the predetermined time elapses. After that, the electrolyzed water is discharged.
According to the fourth invention, by generating vortex in the inflow chamber by discharging the bath water, sebum, hair and the like attached to the inner wall inside the drainage port above the actual sealing water line can be washed away Since the swirling flow is a sealed water formed of dirty water, the dirty water can still be attached to the inner wall inside the drainage port even after the generation of the swirling flow is completed. Therefore, the inner wall inside the drainage port can be washed away by discharging the tap water which is not the electrolyzed water until the predetermined time passes.
In a fifth invention according to the fourth invention, the tap water which is not the electrolyzed water has a length of 300 seconds or more which is a bathtub water discharge equivalent time which is assumed to be a time from the start of discharge of the bath water to completion of discharge. It is characterized in that it is discharged toward the drainage port.
According to the fifth invention, after the vortex flow is completed, tap water which is not electrolyzed water can be discharged, and the inner wall inside the drainage port can be washed out more reliably.

Drawing 2 (a) is a model perspective view of bathroom 500 concerning an embodiment.
FIG. 2B is a schematic perspective view in which the vicinity of the counter 530 in the bathroom 500 is enlarged.
FIG. 3 is a plan view of the bathtub 510.

  As shown in FIG. 2A, the bathroom 500 is surrounded by four walls 541 to 544 and a ceiling 545. In the bathroom 500, a bathtub 510, a washing floor 520, and a counter 530 are provided. Furthermore, in the bathroom 500, a mirror, a faucet device, a hand shower and the like are appropriately provided.

  A first wall 541 and a second wall 542 are provided opposite to each other on a pair of short sides of the bath 510. A fourth wall 544 is provided on one long side of the bathtub 510. Opposite to the fourth wall 544, a third wall 543 is provided on the wash floor 520 side.

  The floor floor 520 is provided with a drainage port 521. In the example shown in FIG. 2A, the drainage port 521 is located near the edge of the washing floor 520 on the bathtub 510 side and substantially in the center of the washing floor 520 in the longitudinal direction.

  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 on the surface (floor surface) of the washing floor 520, it is directed to the drainage port 521. A gentle downward slope (drainage slope) is provided.

  The counter 530 is attached to the second wall 542, for example. The counter 530 is installed at a distance above the surface of the washing floor 520. The counter 530 has a substantially rectangular shape having a long side along the short side direction of the washing floor 520 when viewed from above.

  As shown in FIG. 2B, the counter 530 has a top 531 and a cover 532 covering the lower side of the top 531. The electrolyzed water discharge apparatus 100 shown in FIG. 1 is accommodated in the inside of the counter 530 enclosed by the top plate 531 and the cover 532 except for some elements (the water stop valve 50 and the water discharger 10).

  The water discharge part (nozzle part) 10 is provided so that it may protrude below the counter 530, as shown in FIG.2 (b). The water discharger 10 is separated from the surface of the washing floor 520. Further, the water discharger 10 is installed near the center of the counter 530 in the widthwise direction (short side direction). That is, the water discharger 10 is installed at one end side in the longitudinal direction of the washing floor 520 and near the center in the short side direction. By the rotational operation of the water discharger 10, which will be described later, at this position, the tap water and the electrolyzed water can be easily discharged over substantially the entire floor floor 520.

  As shown in FIG. 3, a drainage plug 511 is provided on the bottom of the bath 510. The drainage plug 511 opens and closes the bathtub drainage port formed on the bottom of the bathtub 510. A drain plug button 512 is provided on the rim of the bath 510, and the drain plug 511 is opened and closed by operation of the drain plug button 512.

  The water stop valve 50 shown in FIG. 1 is connected to a water supply pipe to which tap water is supplied. The water stop valve 50 is connected to the strainer 51. The downstream side of the strainer 51 is connected to a constant flow valve 52, and the downstream side of the constant flow valve 52 is branched into two pipes 61 and 62.

  A solenoid valve 53 is provided in one of the pipes 61, and the downstream side of the solenoid valve 53 is connected to the first water outlet 11 of the water discharger 10. Further, for example, in a cold region, the water removal valve 54 is connected between the solenoid valve 53 and the water discharger 10 as needed.

  The strainer 55, the solenoid valve 56, the pressure regulating valve 57, the check valve 59, the electrolyzed water generating unit 20, the strainer 65, and the second water outlet 12 of the water discharging unit 10 are connected to the other pipe 62 sequentially from the upstream side. It is done. In addition, a safety valve 58 is connected between the pressure regulating valve 57 and the check valve 59.

  In addition, the electrolyzed water discharge device 100 includes a motor (for example, a stepping motor) 66 that causes the water discharger 10 to rotate (turn). The motor 66 is also accommodated inside the counter 530.

  The control unit 40 controls the operations of the solenoid valve 53, the solenoid valve 56, the electrolyzed water generator 20, and the motor 66. The power supply 30 supplies power to them. Also, the power supply 30 supplies power to the operation unit 35. The power supply 30 is installed, for example, behind the ceiling 545 of the bathroom 500 as shown in FIG. 2 (a). The control unit 40 is installed inside the counter 530 or behind the ceiling 545 of the bathroom 500.

  The solenoid valve 53 is opened and closed under the control of the control unit 40. When the solenoid valve 53 is opened, tap water is spouted from the first spout 11. When the solenoid valve 53 is closed, the tap water is not spouted from the first spout 11.

  The solenoid valve 56 is opened and closed under the control of the control unit 40. When the solenoid valve 56 is opened, tap water is supplied to the electrolyzed water generating unit 20, and the electrolyzed water generated by the electrolyzed water generating unit 20 is discharged from the second water discharge port 12. When the solenoid valve 56 is closed, the electrolyzed water is not discharged from the second water outlet 12.

  By controlling the pressure of the tap water by the pressure control valve 57, the flow rate of the tap water supplied to the electrolyzed water generating unit 20 is adjusted. By adjusting the flow rate of the tap water supplied to the electrolyzed water generation unit 20, the flow rate of the electrolyzed water discharged from the second water discharge port 12 is adjusted.

  Further, the flow rate of the tap water supplied to the downstream side can be adjusted by the solenoid valves 53, 56.

  The electrolyzed water generating unit 20 generates electrolyzed water. This electrolyzed water is disinfected water having a disinfecting action. The electrolyzed water generating unit 20 is, for example, an electrolytic cell having an anode and a cathode. By applying a voltage between the anode and the cathode to electrolyze the tap water flowing between the anode and the cathode, the tap water is denatured into electrolyzed water. Since tap water contains chloride ions, hypochlorous acid is produced by electrolyzing the chloride ions.

  Hypochlorous acid has the ability to kill the fungus and further inhibit the growth of the fungus. Therefore, the electrolyzed water is a disinfected water containing hypochlorous acid and having a disinfecting action.

  FIG. 4 is a perspective view of the water discharger 10.

  The water discharger 10 is formed in a cylindrical shape, and the first water outlet 11 and the second water outlet 12 are provided on the lower side surface thereof. The first spout 11 and the second spout 12 are each formed in the shape of a vertically long slit.

  The first spout 11 and the second spout 12 are arranged side by side in the circumferential direction of the cylindrical spout 10. Alternatively, the first spout 11 and the second spout 12 may be arranged side by side in the height direction.

  From the first outlet 11, tap water which is not electrolyzed water is discharged to the washing floor 520. From the second water discharge port 12, the above-described electrolyzed water (sterilized water) is discharged to the washing floor 520. Tap water or electrolyzed water can be temporarily stored in the cylindrical water discharger 10, and the water discharge pressure can be increased.

  Tap water that has fan-likely spread in the longitudinal direction (vertical direction) can be spouted from the vertically long first spout 11. Electrolyzed water fanned in the longitudinal direction (vertical direction) can be spouted from the vertically elongated second spout 12 as well.

  By driving the motor 66 described above, the cylindrical water discharger 10 can be rotated around its central axis (indicated by a dot-and-dash line in FIG. 4) to change the direction in which tap water or electrolyzed water is discharged. .

  Fig.5 (a) is a model perspective view of the drainage trap 70 which concerns on embodiment, FIG.5 (b) is a schematic cross section of the drainage trap 70. As shown in FIG.

  The drainage trap 70 is installed below the drainage port 521 formed in the washing floor 520. A drainage weir 91 is integrally formed in a concave shape on the washing floor 520, and a drainage trap 70 is connected to the lower part of the drainage weir 91. The upper surface of the drainage weir 91 is covered with a drainage cover 95 shown in FIG. 2 (a).

  A flange member 92 is attached to the bottom side of the drainage weir 91 via a packing, and the upper end of the drainage trap 70 is attached to the flange member 92. In the flange member 92, a hair catcher 81 is attached detachably from above.

  Above the main body 80 of the drainage trap 70, an opening 93 for the inflow of washing place drainage is provided. The drainage from the washing floor 520 side passes through the drainage weir 91 and flows into the drainage trap 70 from the opening 93.

  A bathtub drainage inlet 78 is formed at the side of the main body 80 of the drainage trap 70. The bathtub drainage inlet 78 is connected to the bathtub drainage through a pipe connected to the bathtub drainage inlet 78.

  An outlet 79 is formed on the opposite side of the bathtub drainage inlet 78. The bathtub drainage, the washing place drainage, the electrolyzed water and the like flowing into the drainage trap 70 flow out through the outlet 79 to the drainage pipe connected to the outlet 79.

  A sealed water wall 77 raised integrally with the bottom surface 72 of the main body 80 is formed on the upstream side of the outlet 79. The upper end of the sealing water wall 77 is the height of the sealing water surface W.

  On the upstream side of the water sealing wall 77, a shielding member 76 vertically provided from the top surface 71 in the main body 80 of the drainage trap 70 is provided. The shielding member 76 divides the inside of the drainage trap 70 into two chambers, an inflow chamber 73 and an outflow chamber 74. A communication portion 75 is formed between the lower end of the shielding member 76 and the bottom surface 72 of the drainage trap 70 to allow the inflow chamber 73 and the outflow chamber 74 to communicate with each other. The communicating portion 75 is provided at a portion submerged in sealing water between the shielding member 76 and the bottom surface 72.

  A bathtub drainage inlet 78 is formed on the side of the inflow chamber 73, and the bathtub drainage inlet 78 is in communication with the inlet chamber 73. An outlet 79 is formed substantially opposite to the bathtub drainage inlet 78, and the outlet 79 is in communication with the outlet chamber 74. In the top surface (upper side) of the inflow chamber 73, an opening 93 for inflow of the washing water is formed.

  The drainage trap 70 is configured to generate a vortex in the inflow chamber 73 when the bathtub drainage introduced from the bathtub drainage inlet 78 collides with the shielding member 76. The bathtub drainage that has flowed into the inflow chamber 73 swirls along the inner circumferential surface of the drainage trap 70 and the shielding member 76 to form an eddy current. The swirling current is guided by the shielding member 76 to be a rising swirling flow and is raised inside the main body 80 because the shielding member 76 is inclined in a diameter-expanding manner from the lower end side to the upper side.

  If the inclination angle of the shielding member 76 is set such that the rising vortex flows up to near the upper end of the drainage weir 91, dust or hair attached to the inner circumferential surface of the drainage weir 91 or the hair catcher 81 by the rising vortex. As it is dropped and collected at the center of the vortex and further dropped downward from the center of the vortex, dust and hair are collected at the center of the bottom of the lower end of the hair catcher 81. As a result, the hair catcher 81 is kept in a state in which no hair or the like is attached to the area other than the central portion, and water flow becomes good.

  Drawing 6 (a) is a discharge time chart of electrolysis water in an embodiment.

  When the user operates the operation unit 35 described above (when the operation unit 35 is turned on), the operation unit 35 transmits an execution command of electrolyzed water discharge to the control unit 40. The control unit 40 performs control so as to discharge the electrolyzed water after a predetermined time elapses without receiving the electrolyzed water until the predetermined time elapses after receiving the execution command of the electrolyzed water discharge from the operation unit 35 .

  That is, after the user has completed the use of a bathroom such as bathing, the user operates the water drain button 512 shown in FIG. 3 to open the water drain plug 511 of the bathtub 510 and operates the operation unit 35, dare to take predetermined time The electrolyzed water is discharged after a predetermined time has elapsed without discharging the electrolyzed water until the time elapses.

  FIGS. 7 (a) to 7 (c) are schematic cross-sectional views for explaining the generation of a vortex in the drainage trap 70 and the inflow of electrolyzed water in the embodiment.

  FIG. 7A shows a state in which the drainage plug 511 of the bathtub 510 is closed and bathtub drainage does not flow into the drainage trap 70. Then, when the drainage plug 511 of the bathtub 510 is opened, the bathtub drainage flowing in from the bathtub drainage inlet 78 collides with the shielding member 76, whereby a swirling flow is generated in the inflow chamber 73. As shown in FIG. 7 (b), the vortex generates a centrifugal force in the seal water, and temporarily the water level W 'of the seal water line where the drainage trap 70 and the seal water contact is raised. Thus, sebum and hair attached to the inner wall (the inner wall of the drainage weir 91 and the inner wall of the drainage trap 70) inside the drainage port 521 above the actual sealing water line W defined by the height of the sealing water wall 77 Etc. can be washed away.

  Then, after a predetermined time has elapsed since the operation unit 35 was operated, the control unit 40 causes the water discharge unit 10 to discharge the electrolyzed water toward the drainage port 521, and the electrolyzed water is discharged as shown in FIG. It flows into the drainage trap 70 from the port 521.

  As a result of the water level rising due to the occurrence of the vortex flow, sebum and the like on the path until the electrolyzed water flowing from the drainage port 521 reaches the original sealing water line W are washed away. Therefore, it is possible to suppress a decrease in the concentration of the bactericidal component of the electrolyzed water due to the contact with the sebum attached to the inner wall inside the drainage port 521 before reaching the original sealing water line W where blackening tends to occur. That is, the electrolyzed water can be made to flow into the sealing water line W inside the drainage port 521 (the drainage trap 70) without reducing the concentration of the germicidal component. Therefore, even when electrolyzed water is used as disinfecting water, generation of darkening in the sealing water line W can be appropriately suppressed.

  Here, for a predetermined time, when the general size of the bath is almost full, for example, the bath water starts to be discharged from 90% of the allowable water level of the bath and the bath water starts to be discharged. It is a length of 300 seconds or more, which is the time required to complete the bath water discharge equivalent time. After this predetermined time has elapsed, the electrolyzed water is continuously discharged, for example, for 390 seconds.

  By setting the predetermined time to a length longer than such a bathtub water discharge equivalent time, after the bathtub water discharge is completed, that is, the temporary rise of the water level due to the generation of the vortex in the drainage trap 70 After finishing (after the vortex disappears), the electrolytic water can flow into the drainage trap 70. Thereby, the waste of the electrolyzed water discharged | emitted with a eddy current can be eliminated and electrolyzed water can be reliably made to flow in the original sealing water line.

  The operation unit 35 can also send an execution command of electrolyzed water discharge to the control unit 40 by the operation of the user, and can also open the drainage plug 511 of the bathtub 510. That is, when the operation unit 35 is operated by the user, not only the execution command of electrolyzed water discharge is transmitted to the control unit 40, but also the drainage plug 511 of the bathtub 510 is opened.

  Even if the user does not operate the drain plug button 512, the electrolyzed water is output after the predetermined time has elapsed since the drain plug 511 of the bath 510 is more reliably opened in conjunction with the operation of the operation unit 35. The water is discharged toward the drainage port 521. That is, after the sebum, the hair and the like attached to the inner wall inside the drainage port 521 above the sealing water line are surely washed away by the vortex flow, the electrolytic water can be made to flow toward the drainage port 521. Thereby, the electrolyzed water which suppressed the fall of the bactericidal component density | concentration can be reliably made to flow in a sealing water line.

FIG. 6 (b) is a discharge time chart of tap water and electrolyzed water in another embodiment.
Fig.8 (a)-FIG.9 (b) are schematic cross sections for demonstrating the effect | action of the sealing water in a drainage trap, a tap water, and electrolyzed water along the time chart shown to FIG. 6 (b). .

  In this example, when the execution command is received, the control unit 40 discharges tap water that is not electrolyzed water toward the drainage port 521 until a predetermined time passes. Then, after the execution command is received, the electrolyzed water is discharged after a predetermined time (during which the tap water is discharged) has elapsed.

  FIG. 8A shows a state in which the drainage plug 511 of the bathtub 510 is closed and bathtub drainage does not flow into the drainage trap 70. Then, when the drainage plug 511 of the bathtub 510 is opened, as shown in FIG. 8B, the bathtub drainage which has flowed in from the bathtub drainage inlet 78 collides with the shielding member 76, thereby generating a swirl in the inlet chamber 73. Do.

  By generating vortices in the inflow chamber 73 by discharging the bath water, although sebum and hair and the like attached to the inner wall inside the drainage port 521 above the actual sealing water line can be washed away, the vortices are dirty water. Since the sealing water is formed, the dirty water may still be attached to the inner wall of the drainage weir 91 and the drainage trap 70 even after the generation of the vortex flow is completed. Therefore, by discharging the tap water which is not the electrolyzed water until the predetermined time passes, the inner wall of the drainage weir 91 and the drainage trap 70 can be washed away.

  The tap water which is not the electrolyzed water is discharged toward the drainage port 521 for a length of 300 seconds or more which is the above-described bathtub water discharge equivalent time. For example, when the operation unit 35 is turned on, tap water is discharged intermittently. In the example shown in FIG. 6 (b), tap water is intermittently discharged twice in 480 seconds. Electrolyzed water is continuously discharged for 390 seconds, for example, 240 seconds after the end of the discharge of tap water.

  By discharging tap water with a length longer than the above-mentioned bathtub water discharge equivalent time, as shown in FIG. 9 (a), after vortex generation is completed, the inner wall inside the drainage port 521 is surely washed away with tap water. Can. Thereafter, as shown in FIG. 9B, the electrolyzed water in which the decrease in the concentration of the germicidal component is suppressed flows into the drainage trap 70 from the drainage port 521.

  In addition, the water discharger 10 discharges the tap water, which is not the electrolyzed water, toward the washing floor 520 before the predetermined time passes. That is, while the vortex flow is generated in the inflow chamber 73 of the drainage trap 70, sebum dirt and the like on the surface of the washing floor 520 can be washed away with the tap water, and then the electrolytic water can be discharged. Therefore, it is possible that sebum dirt on the surface of the washroom floor 520 may flow into the drainage port 521 after the discharge of electrolyzed water is started by washing the sebum dirt on the surface of the washroom floor 520 in advance with tap water. It can be suppressed.

  The tap water is discharged for a length of 300 seconds or more, which is the above-described bathtub water discharge equivalent time. Thus, as shown in FIG. 9A, the tap water which is not the electrolyzed water can be discharged until after the eddy current generation is completed, and the tap water which has washed the washing floor 520 is used more reliably. The inner wall inside the drainage port 521 can be washed away.

  In the present embodiment, for example, the discharge flow velocity of the electrolyzed water from the water discharge unit 10 is 9 (m / s) or more and 11 (m / s) or less, and the discharge flow velocity of the tap water from the water discharge unit 10 is 5.6 ( m / s).

  In addition, the electrolyzed water and the tap water are discharged in granular form, respectively. For example, the particle size of electrolyzed water is 800 (μm), and the particle size of tap water is 0.3 (mm) or more and 3.5 (mm) or less.

  The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to them, and various modifications are possible based on the technical idea of the present invention.
