Description

The present invention relates to a bathroom cleaning device.

Conventionally, a bathroom cleaning device that effectively suppresses the generation of dirt on the washing floor by supplying tap water to the washing floor to remove organic substances on the washing floor and then supplying sterilizing water to the washing floor. It is known (for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2008-168231

In order to more reliably control the dirt on the washing floor, it is sufficient to use sterilizing water with a very high sterilizing ability, but in the bathroom used by people, use such sterilizing water with a very high sterilizing ability. That is not desirable. Therefore, in order to prevent the washing floor from becoming dirty without using such sterilized water, we conducted a diligent study. As a result, there are black mold and pink stains on the washing floor, and it is very effective to remove organic substances such as keratin, which is a nutrient source for black mold, from the washing floor in order to control the black mold. In order to control pink stains, it is not enough to remove organic matter, which is a nutrient source, from the washing floor, and in addition, it is very possible to reduce the number of methylobacterium present on the washing floor. It was found that it produces a high effect.

In addition, black mold is often generated when fungi floating in the air adhere to the floor surface of the washing place, whereas methylobacterium is often contained in tap water, so the floor surface of the washing place. It was also possible to obtain a new finding that a large amount of water containing methylobacterium remains on the floor surface of the washing place immediately after the tap water is supplied.

Therefore, especially to suppress pink stains, tap water is supplied to the washroom floor to wash away organic substances, and then water having a smaller number of methylobacterium than tap water is supplied to the washroom floor and remains on the washroom floor. It was found that it is effective to replace the tap water with water that has a smaller number of methylobacterium than tap water. Therefore, it is desirable to provide such a bathroom cleaning mode.

Here, in the daytime, the bathroom is often used by a plurality of people in turn, especially during the night time. If each user performs the above wash mode with water low in methylobacterium each time after use, the next user's bathroom will be used except by the last user of the day. This causes water with a low number of methylobacterium to flow away from the washroom floor. Therefore, it does not make much sense for a user other than the last user to supply water with a low number of methylobacterium to the washing floor each time it is used, and water with a low number of methylobacterium is wasted. turn into.

On the other hand, when only the last user executes the above washing mode, organic substances such as keratin remaining on the washing floor after each user's use will be dried and washed before the next user uses the bathroom. It sticks to the floor and the sticking organic matter accumulates on the floor of the washing place with each use of the user, so even if the above cleaning mode is executed after the last user finishes using the bathroom, it accumulates. It is difficult to remove the adhered organic matter, and a large amount of organic matter may remain after the cleaning mode is completed. In this case, stains such as black mold are likely to occur when the bathroom is not used.

An object of the present invention is to provide a bathroom cleaning device capable of reducing the amount of organic substances remaining on the floor surface of a washing place without wasting water having a small number of methylobacterium.

The bathroom cleaning device of the first invention has an organic substance removing step of spouting tap water onto the floor surface of the washing place of the bathroom to remove organic substances adhering to the floor surface of the washing place, and reforming the tap water into tap water. A control device capable of performing a replacement step for discharging the reformed water in which the number of metyrobacterium contained is reduced and replacing the tap water remaining on the floor surface of the washing place with the reformed water. The control device is characterized by having a first mode in which only the organic substance removing step is executed, and a second mode in which the replacement step is executed after executing the organic substance removing step. ..
According to the first invention, when a plurality of users use the bathroom in turn, for example, a user other than the last user does not execute the second mode after using the bathroom. Only one mode (only the organic matter removal step) can be executed. In that case, the reformed water with the reduced number of methylobacterium is not discharged to the washing floor. Therefore, the reformed water does not flow away from the floor surface of the washing place by the next use of the bathroom of the user, and the reformed water is not wasted.
On the other hand, by executing the first mode for each use of a user other than the last user, organic substances such as keratin remaining on the floor of the washing place due to the use of the previous user are washed away, and the next user is in the bathroom. It is possible to prevent the product from drying and sticking to the bathroom floor before it is used. Therefore, when the second mode is executed after the last user has finished using the bathroom, there is little accumulated organic matter on the washing floor, and the organic matter remaining on the washing floor after the completion of the second mode. The amount can be reduced. Therefore, it is possible to prevent black mold and the like from multiplying and causing stains due to organic substances remaining on the washing floor after the last use by the user.
According to the second invention, in the first invention, the first mode is a short-time mode in which the tap water spouting time is short, and a long-time mode in which the tap water spouting time is longer than the short-time mode. It is characterized by having.
According to the second invention, the completion time of the organic matter removing step can be selected according to the usage interval of a plurality of bathroom users. When the short-time mode is selected, it is possible to reduce the amount of residual organic matter while suppressing the occurrence of waiting time for the next user. When the long-time mode is selected, the washing floor can be thoroughly washed and the amount of residual organic matter can be reduced more effectively.

According to the bathroom cleaning device of the present invention, it is possible to effectively suppress the generation of stains on the washing floor, particularly black mold and pink stains, without wasting water having a small number of methylobacterium.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In order to facilitate understanding of the description, the same components are designated by the same reference numerals as much as possible in each drawing, and duplicate description is omitted.

FIG. 1 is a system block diagram showing the overall configuration of the bathroom cleaning device 1 of the embodiment.

The bathroom cleaning device 1 of the embodiment includes a power supply 30, a control device 40, an operation unit 35, and a functional unit 100. The functional unit 100 is installed on the bathroom counter.

FIG. 2A is a schematic perspective view of the bathroom 500 in which the bathroom cleaning device 1 is installed.
FIG. 2B is an enlarged schematic perspective view of the vicinity of the counter 530 in the bathroom 500.

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

A first wall 541 and a second wall 542 are provided on the pair of short sides of the bathtub 510 so as to face each other. A fourth wall 544 is provided on one long side of the bathtub 510. A third wall 543 is provided on the washing floor 520 side so as to face the fourth wall 544.

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

On the floor surface of the washroom floor 520, a gentle descent 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 toward the drainage port 521. There is a slope (drainage slope).

The counter 530, mirror, faucet device, and hand shower are mounted, for example, on a second wall 542.

The counter 530 is installed so as to be separated from the floor surface of the washing place floor 520. The counter 530 has a substantially rectangular shape having a long side along the lateral direction (short side direction of the washing place floor 520) when viewed from above.

The counter 530 has a top plate 531 and a cover 532 that covers the bottom of the top plate 531. The functional unit 100 of the bathroom cleaning device 1 shown in FIG. 1 is housed inside a counter 530 surrounded by a top plate 531 and a cover 532, except for some elements (water stopcock 50, water discharge unit 10). ..

As shown in FIG. 2B, the water discharge portion (nozzle portion) 10 is provided so as to project below the counter 530. The water spouting portion 10 is separated from the floor surface of the washing place floor 520. Further, the water discharge unit 10 is installed near the center of the counter 530 in the lateral width direction. That is, the water discharge portion 10 is installed on one end side in the longitudinal direction of the washing place floor 520 and near the center in the short side direction. The rotational operation of the water spouting unit 10 described later at this position facilitates spouting tap water or the like to substantially the entire washing floor 520.

The water stopcock 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 the constant flow valve 52, and the downstream side of the constant flow valve 52 is branched into two hoses 61 and 62.

One hose 61 is provided with a solenoid valve 53, and the downstream side of the solenoid valve 53 is connected to the first water discharge port 11 of the water discharge unit 10. Further, for example, in a cold region, a drain valve 54 is connected between the solenoid valve 53 and the water discharge unit 10 as needed.

The other hose 62 has a strainer 55, a solenoid valve 56, a pressure regulating valve 57, a check valve 59, an antibacterial water generating section 20, a strainer 65, and a second spout 12 of the spouting section 10 in this order from the upstream side. It is connected. Further, a safety valve 58 is connected between the pressure regulating valve 57 and the check valve 59.

Further, the functional unit 100 has a motor (for example, a stepping motor) 66 that rotates (turns) the water discharge unit 10. This motor 66 is also housed inside the counter 530.

The control device 40 controls the operations of the solenoid valve 53, the solenoid valve 56, the bacteriostatic water generator 20, and the motor 66. The power supply 30 supplies them with power. Further, the power supply 30 supplies electric power to the operation unit 35. The power supply 30 is installed, for example, behind the ceiling 545 of the bathroom 500. The control device 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 device 40. When the solenoid valve 53 is opened, tap water is discharged from the first spout 11 as cleaning water. When the solenoid valve 53 is closed, the washing water is not discharged from the first water discharge port 11.

The solenoid valve 56 is opened and closed under the control of the control device 40. When the solenoid valve 56 is opened, tap water is supplied to the antibacterial water generation unit 20, and the antibacterial water generated by the antibacterial water generation unit 20 is discharged from the second spout 12. When the solenoid valve 56 is closed, the bacteriostatic water is not discharged from the second spout 12.

The flow rate of tap water supplied to the bacteriostatic water generation unit 20 is adjusted by controlling the pressure of tap water by the pressure regulating valve 57. By adjusting the flow rate of tap water supplied to the bacteriostatic water generation unit 20, the flow rate of the bacteriostatic water discharged from the second spout 12 is adjusted.

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

The bacteriostatic water generation unit 20 generates bacteriostatic water. Here, the bacteriostatic water has a bactericidal ability or an ability to suppress the growth of bacteria. The bacteriostatic water generation 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 transformed into bacteriostatic water.

Moreover, since tap water contains chloride ions, hypochlorous acid is produced by electrolyzing the chloride ions. Therefore, the bacteriostatic water is, for example, water containing hypochlorous acid.

The methylobacterium contained in tap water is killed in the electrolytic cell by the hypochlorous acid-containing water produced by electrolysis. Therefore, bacteriostatic water is reformed water in which the number of live methylobacterium contained in tap water is reduced (including zero) by reforming tap water. That is, the reformed water is water in which the average number of methylobacterium contained per unit volume is smaller than that of tap water (including water having zero number).

The bacteriostatic water may be, for example, metal ionized water containing metal ions such as silver ion, copper ion, and zinc ion, or water containing ozone. For example, when tap water is electrolyzed, acid (H ⁺ ) is consumed at the cathode and the pH rises 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 drops in the vicinity of the anode. That is, acidic water is generated in the vicinity of the anode. By changing the flow rate in the bacteriostatic water generation unit 20, the concentration of the component contained in the bacteriostatic water can be controlled.

The bacteriostatic water generation unit 20, which is also a reformed water generation unit, is not limited to the configuration having an electrolytic cell, and for example, a bactericidal agent or a sterilizing agent is dissolved in tap water to generate bacteriostatic water (modified water). You may. At this time, the methylobacterium contained in the tap water is killed by the disinfectant or the disinfectant, the number of the methylobacterium is reduced in the second spout 12, and the water containing the disinfectant or the disinfectant is contained. Is supplied. Alternatively, the modified water generation unit (bacteriostatic water generation unit) 20 may be configured to reduce the number of methylobacterium by ultraviolet irradiation, boiling, a filter, or the like. Further, the modified water may be generated by the user putting a bactericidal agent or a disinfectant into a tank in which tap water is stored. In this case, a pump or the like may be used to discharge the reformed water.

The control device 40 executes a first mode or a second mode, which will be described later, in response to an operation command (electric signal) of the operation unit 35.

FIG. 4 is a front view of the operation unit 35.

The operation unit 35 is installed outside the bathroom 500. The operation unit 35 is installed, for example, in a washroom (dressing room) next to the bathroom 500. Alternatively, the operation unit 35 may be installed in the bathroom 500.

The operation unit 35 has a stop button 71 and two wash buttons 72 and 73. When the wash button 72 is pressed, the first mode is executed, and when the wash button 73 is executed, the second mode is executed. If the stop button 71 is pressed during the execution of the first mode or the second mode, the execution of the first mode or the second mode is stopped.

When the cleaning button 72 is pressed and the first mode is executed, the lighting unit 74 provided next to the cleaning button 72 lights up. When the cleaning button 73 is pressed and the second mode is executed, the lighting unit 75 provided next to the cleaning button 73 lights up.

FIG. 3 is a perspective view of the water discharge unit 10.

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

The first spout 11 and the second spout 12 are arranged 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.

Tap water is discharged from the first spout 11 to the washing floor 520. From the second spout 12, antibacterial water (modified water) in which the number of methylobacterium is reduced is discharged to the washing place floor 520. Tap water or bacteriostatic water can be temporarily stored in the cylindrical water discharge portion 10, and the water discharge pressure can be increased.

Tap water spread in a fan shape in the vertical direction (vertical direction) can be discharged from the vertically long first spout 11 as shown by a solid arrow in FIG. Similarly, from the vertically long second spout 12, as shown by the broken line arrow in FIG. 3, the bacteriostatic water spread in a fan shape in the vertical direction (vertical direction) can be discharged.

By driving the motor 66 described above, the cylindrical water discharge portion 10 can be rotated around its central axis (indicated by the alternate long and short dash line in FIG. 3) to change the direction in which tap water or bacteriostatic water is discharged. can.

The bathroom cleaning device 1 of the embodiment described above executes the first mode and the second mode. The first mode and the second mode are not executed at the same time, and only one of the first mode and the second mode can be operated by the operation of the cleaning button 72 or the cleaning button 73 of the operation unit 35 shown in FIG. It is executed alternately.

The first mode performs only the organic matter removal step. This organic substance removing step is a step of spouting tap water from the first spout 11 to substantially the entire floor surface of the washing place in the bathroom to remove organic substances such as keratin (protein) adhering to the floor surface of the washing place.

In the second mode, the organic matter removing step by spouting tap water is executed, and the organic matter removing step is executed, and then the replacement step is executed. This replacement step is a step of spouting water having a reduced number of methylobacterium from the second spout 12 to the floor surface of the washing place. On the floor surface of the washing place before the replacement step, tap water discharged in the organic matter removal step executed before the replacement step, that is, water containing a large amount of methylobacterium remains. In the replacement step, reformed water containing a reduced number of methylobacterium in tap water is discharged onto the floor of the washing place, and tap water remaining on the floor of the washing place is reduced in the number of methylobacterium. This is a step of replacing with reformed water.

FIG. 5 is a flowchart of the first mode.

The first mode is started by operating the cleaning button 72 shown in FIG. First, when the first spout 11 is not at a position facing a predetermined direction (standby position or spout start position), the origin is set. That is, the tap water is not discharged from the first spout 11 and the bacteriostatic water (modified water) is not spouted from the second spout 12, and the spout portion 10 is rotated to make the first spout. The spout 11 is moved to the standby position. When the origin of the first spout 11 is set, the origin of the second spout 12 is also set at the same time. Conversely, when the origin of the second spout 12 is set, the origin of the first spout 11 is also set at the same time.

After the origin is set, tap water is discharged from the first spout 11, and the spout portion 10 is rotated to wash substantially the entire floor surface of the washing place floor with tap water. Further, the origin may be set after the tap water discharge step is completed.

By executing this first mode, organic substances such as keratin remaining on the floor surface of the washing place floor are discharged from the first spout 11 and the tap water is discharged from the floor surface after landing. It is carried to the drainage port by the flow of tap water flowing toward, and is removed from the floor.

By removing organic substances such as keratin from the floor surface of the washroom floor, it is possible to suppress the growth of methylobacterium, which is the main nutrient source for it, and further, the washroom floor caused by methylobacterium. Pink stains can be suppressed. In addition, the growth of other microorganisms such as fungi that use organic matter as a nutrient source can be suppressed.

In the first mode, only the organic matter removal step with tap water is performed, and the replacement step with modified water (bacteriostatic water) in which the number of methylobacterium is reduced is not performed.

In this first mode, not only keratin but also soap scum, shampoo residue, hair and the like remaining on the floor surface can be washed away to the drain port.

FIG. 6 is a flowchart of the second mode.

The second mode is started by operating the cleaning button 73 shown in FIG. First, as in the first mode, tap water is discharged from the first spout 11 to perform an organic matter removing step.

Then, after this organic matter removing step (after the discharge of tap water is completed), the above-mentioned replacement step is performed.

First, when the second spout 12 is not at a position facing a predetermined direction (standby position or spout start position), the origin is set. That is, the bacteriostatic water (modified water) is not discharged from the second spout 12, and tap water is not spouted from the first spout 11, and the spout portion 10 is rotated to make the second spout. The spout 12 is moved to the standby position.

Then, for example, while discharging the above-mentioned bacteriostatic water as modified water in which the number of methylobacterium is reduced from the second spout 12, the water discharge unit 10 is rotated to reduce the number of methylobacterium. The reformed water (antibacterial water) is supplied to almost the entire floor surface of the washing place floor. Further, the origin may be determined after the step of discharging the reformed water in which the number of methylobacterium is reduced is completed.

By executing the organic matter removal step using tap water in this second mode, organic matter such as keratin is removed from the floor surface of the washing place floor as in the first mode, and the growth of methylobacterium and black mold is suppressed. can. Therefore, black mold and pink stains on the washing floor can be suppressed.

Further, in the second mode, after the organic substance removal step, the modified water (bacteriostatic water) in which the number of methylobacterium is reduced is discharged to the washing place floor surface, and the tap water remaining on the washing place floor surface is discharged. Can be flushed to the drain and the tap water remaining on the floor of the washing place can be replaced with reformed water with a reduced number of methylobacterium.

The tap water used in the organic matter removal process contains a large amount of methylobacterium, but the tap water is washed away from the floor surface, and the residual water on the floor surface is converted into reformed water with a reduced number of methylobacterium. Can be replaced. Therefore, after performing the second mode, there is no organic matter on the floor of the washroom floor, and there is no or few methylobacterium. Therefore, the execution of the second mode is more effective in preventing the occurrence of pink stains than the execution of the first mode.

FIG. 7 is a flowchart of a usage example of the bathroom cleaning device 1 of the embodiment.

The example shown in FIG. 7 represents, for example, an example in which four people use the bathroom in turn on the same day or within 24 hours.

After the first person uses the bathroom, the first person selects and executes the first mode. After this, the second person uses the bathroom. After the second person uses the bathroom, the second person selects and executes the first mode. After this, the third person uses the bathroom. After the third person uses the bathroom, the third person selects and executes the first mode. After this, the fourth person (the last user) uses the bathroom. Then, after using the bathroom, the fourth person selects and executes the second mode.

The 1st to 3rd users other than the last user (4th person) execute the first mode after using the bathroom, and do not execute the second mode. Therefore, the reformed water (antibacterial water) in which the number of methylobacterium is reduced is not discharged to the washing place floor. Therefore, the next user's use of the bathroom will cause the modified water (antibacterial water) with a reduced number of methylobacterium to flow away from the floor of the washing place. Do not waste the reformed water with a reduced number of.

However, since the first mode is executed for each use of the 1st to 3rd users, organic substances such as keratin remaining on the floor of the washing place due to the use of the previous user are washed away, and the next user cleans the bathroom. It is possible to prevent the product from drying and sticking to the washing floor before use. Therefore, when the second mode is executed after the last fourth user has finished using the bathroom, there is little accumulated organic matter on the washing floor, and it remains on the washing floor after the completion of the second mode. It is possible to reduce the amount of organic matter. Therefore, it is possible to prevent black mold and the like from multiplying and causing stains due to organic substances remaining on the washing floor after the last use by the user.

Furthermore, since the organic matter is washed away from the floor of the washing place each time the first to third users use it, it is possible to suppress the growth of black mold and methylobacterium until the next user uses it. ..

There is a long time between the use by the last 4th user and the use by the 1st user the next day, for example. Therefore, by executing the second mode only for the last user, it is possible to make the organic matter and methylobacterium absent or abundant on the floor surface of the washing place, and the length until the next day's use can be achieved. It is possible to enhance the effect of suppressing the occurrence of particularly pink stains during the time.

Further, since the bacteriostatic water generator 20 shown in FIG. 1 is not operated after each of the first to third persons has used it, the running cost can be suppressed, and in the case of an electrolyzer, for example, an anode, a cathode, etc. The life can be extended.

FIG. 7 shows an example of use by four people, but for two, three, five or more people, only the last user executes the second mode, and the users other than the last user are the second. By executing the mode of 1, the above-mentioned effect can be obtained.

8 (a) to 8 (e) are schematic views showing an example of rotational operation of the water discharge unit 10.
9 (a) and 9 (b) are schematic views showing how to wash the washing place floor 520 by the rotational operation of the water discharge unit 10.

9 (a) and 9 (b) are viewed from the counter 530 (shown in FIGS. The layout in which the drainage port 521 is located is shown.

In the standby position shown in FIG. 8A, the spouts 11 and 12 move counterclockwise by an angle θ1 with reference to a position (angle 0 °) facing the wall 542 behind the counter 530 from the front. At this position, it faces the rear wall 542. θ1 is smaller than 45 °.

In the first mode, the first spout 11 discharges tap water, and the counterclockwise rotation of the spout portion 10 causes the position of the angle θ2 shown in FIG. 8 (b) to be changed from the standby position (angle θ1). And after the position of 180 °, it moves to the position of the angle θ3. θ2 is greater than 90 ° and less than 180 °. θ3 is greater than 180 ° and less than 270 °.

By the rotational movement of the spout 11 from the position of θ1 to the position of θ3, the tap water discharged from the spout 11 cleans the area represented by the diagonal hatching in FIG. 9A on the washing floor 520. Organic matter on the territory is washed away towards the drain 521.

The time for the spout 11 to move from the position of θ2 to the position of 180 ° and the time for moving from the position of 180 ° to the position of θ3 are longer than the time for moving from the position of θ1 to the position of θ2. Further, the time for the spout 11 to move from the position of θ2 to the position of 180 ° is longer than the time for moving from the position of 180 ° to the position of θ3. This is adjusted by controlling the angular velocity of the water discharge unit 10.

In this way, by washing the area of the washing place floor 520 that is far from the water spouting part 10 and where tap water is difficult to reach directly or where the water force is likely to be weak, it takes a relatively slow time to wash the area, so that the organic matter in that area is not washed away. The entire floor surface of the washing place floor 520 can be efficiently washed.

In the washing place floor 520, the region behind the water spouting portion 10 and the region near the edge portion 520c farthest from the water spouting portion 10 land on the rear wall 542 and the wall 541 facing the wall, and these walls 542, It can be washed away by running water flowing down the floor along 541.

After the water spouting portion 10 is rotated to the position of θ3 for cleaning, the tap water spouting from the spouting port 11 is temporarily stopped, and the spouting port 11 is rotationally moved to the position of θ4 shown in FIG. 8 (c). θ4 is greater than 270 ° and less than 360 °.

At this time, the spout 11 does not perform spout washing on the washing floor 520, and is merely a move to the next spout start point. Therefore, the spout 11 moves at high speed from the position of θ3 to the position of θ4.

Therefore, the time for the spout 11 to move from the position of θ3 to the position of θ4 is the time for moving from the position of θ1 to the position of θ2, the time for moving from the position of θ2 to the position of 180 °, and the position of 180 °. It is shorter than the time to move from to the position of θ3.

Then, the water discharge unit 10 rotates clockwise, and the water discharge port 11 moves from the position of the angle θ4 to the position of the angle 180 ° shown in FIG. 8 (d) while discharging tap water. The movement time at this time is about the same as the movement time when moving from the position of the angle θ1 to the position of the angle θ2. Alternatively, the spout 11 may move from the position of the angle θ4 to the position of the above θ3 and stop while spouting tap water.

The spout 11 faces the vicinity of the corner between the edges 520d and 520a of the washing place floor 520 at the position of θ4. The area represented by diagonal hatching in FIG. 9B on the washing floor 520 by the tap water discharged from the spout 11 by the rotational movement of the spout 11 from that position to the position of 180 ° (or the position of θ3). Is washed. Organic substances on the region on the wall 520a side of the drain port 521 can be washed away toward the drain port 521 with tap water discharged from the spout 11 that rotates clockwise.

In this way, the water discharge step is performed by rotating the water discharge unit 10, and after the water discharge step is completed, as shown in FIG. 8 (e), the water discharge port 11 is located at θ1 from the position of 180 ° (or the position of θ3). It is returned to the position (standby position). This is the origin setting operation described above with reference to FIGS. 5 and 6. At this time, the spout 11 does not spout tap water and is merely a movement to the standby position. Therefore, the spout 11 moves at high speed from the position of 180 ° to the position of θ1. The movement time for origining is shorter than any of the above-mentioned movement times.

In the second mode as well, the organic matter removing step and the replacement step are performed by rotating the water discharge unit 10 in the same manner as in the first mode.

When the drain port 521 is located in the vicinity of the edge portion 520b opposite to the edge portion 520d shown in FIGS. 9A and 9B, the figure showing the rotational operation of the water discharge portion 10 is shown in FIG. It is a diagram in which a) to (e) are line-symmetrical with respect to a straight line connecting the 0 ° position and the 180 ° position. That is, contrary to the above example, by rotating the water discharge unit 10 in the clockwise direction, washing is first started from the region on the edge portion 520d side of the washing place floor 520, and then the water discharge unit 10 is rotated in the counterclockwise direction. Cleaning is restarted from the area near the corners of the edge portion 520b and the edge portion 520a.

Further, according to the embodiment, the first mode has a short-time mode in which the tap water discharge time is short and a long-time mode in which the tap water discharge time is longer than this short-time mode.

FIG. 10A is a timing chart of the short-time mode, and FIG. 10B is a timing chart of the long-time mode.

The time T1 in the short-time mode and the time T1'in the long-time mode are the times when the spout 11 moves from the standby position (position of θ1) shown in FIG. 8 (a) to the position of θ2 shown in FIG. 8 (b). Represents. The time T1 in the short-time mode is shorter than the time T1'in the long-time mode.

The time T2 in the short-time mode and the time T2'in the long-time mode represent the time for the spout 11 to move from the position of θ2 shown in FIG. 8 (b) to the position of 180 °. The time T2 in the short-time mode is shorter than the time T2'in the long-time mode.

The time T3 in the short-time mode and the time T3'in the long-time mode represent the time for the spout 11 to move from the position of 180 ° shown in FIG. 8 (b) to the position of θ3. The time T3 in the short-time mode is shorter than the time T3'in the long-time mode.

The time T4 in the short-time mode and the time T4'in the long-time mode represent the time for the spout 11 to move from the position of θ3 to the position of θ4 shown in FIG. 8C. The time T4 in the short mode is the same as or shorter than the time T4'in the long mode.

The time T5 in the short-time mode and the time T5'in the long-time mode represent the time for the spout 11 to move from the position of θ4 shown in FIG. 8 (d) to the position of 180 °. The time T5 in the short-time mode is shorter than the time T5'in the long-time mode.

The time T6 in the short-time mode and the time T6'in the long-time mode represent the time for the spout 11 to move from the position of 180 ° shown in FIG. 8 (e) to the position of θ1. The time T6 in the short-time mode is the same as the time T6'in the long-time mode.

The total time of the water discharge process in the short-time mode (T1 + T2 + T3 + T5) is shorter than the total time of the water discharge process in the long-time mode (T1'+ T2'+ T3'+ T5').

The total time T including the process without spouting such as origin setting in the short-time mode is shorter than the total time T'including the process without spouting such as origin setting in the long-time mode.

It is desirable to spout tap water for a longer period of time in order to more reliably prevent organic matter from sticking to the floor of the washing place. The waiting time of the user becomes long.

Therefore, according to the embodiment, by providing the short-time mode and the long-time mode as described above in the first mode, the completion time of the organic matter removing step can be selected according to the usage interval of a plurality of bathroom users. When the short-time mode is selected, it is possible to reduce the amount of residual organic matter while suppressing the user from causing a waiting time. When the long-time mode is selected, the washing floor can be thoroughly washed and the amount of residual organic matter can be reduced more effectively.

As for the second mode, a similar short-time mode and long-time mode can be provided.

Further, the switching between the short-time mode and the long-time mode can be switched, for example, by pressing and holding the button 71 and the button 73 in the operation unit 35 shown in FIG. 4 at the same time for 3 seconds or longer. Immediately after the switching operation, the user can confirm which mode has been switched, for example, a long-time mode when the lighting unit 74 is lit and a short-time mode when the lighting unit 75 is lit. Alternatively, the operation unit 35 may be provided with a dedicated button for switching between the short-time mode and the long-time mode.
