Description

The present invention relates to bathrooms.

A sterilized water discharge device that discharges sterilized water toward the floor of a washroom in a bathroom is known (Patent Document 1). In such a sterilized water discharge device, it is also known that electrolyzed water such as hypochlorous acid water generated by electrolyzing flowing water (tap water) is used as the sterilized water to be discharged. It is By using such electrolyzed water as sterilized water, it is not necessary to prepare or replace a cartridge for storing detergent, etc., compared to the case of using detergent, etc., and it is very convenient to use.

On the other hand, when electrolyzed water such as hypochlorous acid water is used as sterilizing water, the electrolyzed water has the property of sterilizing and returning to water when it comes into contact with bacteria. Therefore, in order to sterilize the surface of the floor of the washing place, it is essential to let electrolyzed water fall directly on the surface of the floor of the washing place.

JP 2009-178470 A Japanese Patent No. 5371337

However, sebum stains and the like washed off from the body of the user of the bathroom often adhere to the surface of the floor of the washing space. In particular, if the floor surface of the washing area is made hydrophilic in order to improve drainage, sebum tends to spread widely over the surface, and sebum stains and the like tend to adhere widely to the surface. Since the surface of the floor of the washing place to which sebum is attached is covered with sebum, the discharged electrolyzed water cannot directly land thereon. For this reason, when the user cleans the bathroom with a sponge or a brush to remove sebum stains, the surface of the floor of the washing area from which the sebum stains have been removed becomes blackened due to bacteria that have propagated using the sebum stains as nutrients. There is a problem that has occurred. That is, even if the electrolyzed water is discharged toward the floor of the washing place, there is still a possibility that a part of the surface of the floor of the washing place will be darkened.

An object of the present invention is to provide a bathroom in which electrolyzed water is easily brought into contact with the surface of the floor of the washing place hidden by sebum stains.

A bathroom according to a first aspect of the invention is a bathroom equipped with an electrolyzed water discharge device capable of discharging electrolyzed water having a sterilizing action toward a floor of the washing space, wherein the surface of the floor of the washing space is such that the floor of the washing space is exposed to the atmosphere. The electrolyzed water discharge device has an oil contact angle of 16° or more, which is a contact angle of an oil droplet of 1 μL made of oleic acid when the oil droplet is held horizontally at normal temperature and is present on the surface. It is characterized in that the electrolyzed water is discharged downward at an angle of 0° or more and 16° or less with respect to the horizontal direction.
According to the first invention, electrolyzed water can be obliquely discharged toward the surface of the floor of the washing space at a discharge angle sharper than the oil contact angle of the floor of the washing space. The electrolyzed water sharply discharged from such an oblique direction tends to enter between the sebum stain and the surface of the floor 520 of the washing place. Therefore, it becomes easier for the electrolyzed water to come into contact with the surface of the floor of the washing place hidden by the sebum dirt, and as a result, the surface of the floor of the washing place can be thoroughly sterilized.
While making the surface of the floor of the washing area hydrophilic, the oil repellency should not be too low (oil contact angle α should be 16° or more), and the spread of sebum stains on the surface should be suppressed, so that sebum stains can adhere widely to the surface. You can avoid it. By discharging the electrolyzed water at a sharp discharge angle (0° or more and 16° or less) equal to or less than the oil contact angle, the electrolyzed water can penetrate between the sebum stain and the surface of the floor of the washing place.
The electrolyzed water that has entered between the sebum stain and the surface of the washing space floor acts to disinfect the surface of the washing space floor, and then returns to water, and the sebum stain is easily discharged along with the water to the drain port. . For this reason, an effect unexpected even by a person skilled in the art was produced in that sebum stains are less likely to come into contact again with the surface of the washing place floor that has been thoroughly sterilized.
According to a second invention, in the first invention, the surface of the floor of the washing place is inclined, and the electrolyzed water discharge device is arranged so that the electrolyzed water enters the inclined surface of the floor of the washing place from below. It is characterized in that the water is discharged so as to land on the surface of the floor at a landing angle of 0° or more and 16° or less.
According to the second invention, sebum stains adhering to the surface of the slanted washroom floor tend to be inclined in the slanting direction according to gravity. In this state, the electrolyzed water is discharged so as to enter from below on the surface of the slanted floor of the washing place and land on the surface of the floor of the washing place at a landing angle of 0° or more and 16° or less. . This allows the electrolyzed water to enter between the sebum stain and the surface of the floor of the washroom more effectively.
According to a third aspect of the present invention, in the second aspect, the apparatus further comprises an operation unit for discharging electrolyzed water by being operated by a user, and when the operation unit is operated, tap water that is not electrolyzed water is first tilted. After discharging electrolyzed water at a downward discharge angle of 0° or more and 16° or less with respect to the horizontal direction so that it enters from below on the surface of the washing place floor that is inclined, electrolyzed water enters from below on the surface of the inclined washing place floor. , the ink is discharged at a downward discharge angle of 0° or more and 16° or less with respect to the horizontal direction.
According to the third invention, tap water has the action of separating sebum stains from the surface of the washing place floor, and electrolyzed water has the action of entering between the sebum stains and the surface of the washing place floor to sterilize the surface of the washing place floor. can be made Therefore, it is possible to prevent the electrolyzed water from contacting the sebum stains unnecessarily in order to separate the sebum stains from the surface of the floor of the washing place, so that the electrolyzed water can be made to act on the surface of the floor of the washing place more effectively.
In a fourth invention based on the third invention, when the operation unit is operated, tap water, which is not electrolyzed water, is first poured downward in the horizontal direction so as to enter from below the inclined surface of the floor of the washing place. After discharging the electrolyzed water and tap water at a discharge angle of 0° or more and 16° or less, the electrolyzed water and the tap water are not discharged until a predetermined time has passed, and after the predetermined time has passed, the electrolyzed water is discharged from the inclined surface of the floor of the washing place. is discharged at a downward discharge angle of 0° or more and 16° or less with respect to the horizontal direction so as to enter from below.
According to the fourth invention, if electrolyzed water is discharged onto the floor of the washing place immediately after the tap water has landed on the floor of the washing place, the concentration of the sterilizing component in the precious electrolyzed water will be reduced by the remaining tap water. It becomes diluted. Therefore, after discharging the tap water to the floor of the washing place, electrolyzed water and tap water are not discharged until a predetermined time has passed, and after the predetermined time has passed, the electrolyzed water is discharged toward the floor of the washing place. Electrolyzed water can effectively act on the surface of the floor of the washing place.
A fifth invention is characterized in that, in the third or fourth invention, tap water that is not electrolyzed water is discharged not only to the floor of the washing place but also to the inner wall of the bathroom forming the bathroom.
According to the fifth invention, the tap water can enter between the sebum stain and the surface of the washing space floor so as to sandwich the sebum stain from both sides, and the sebum stain can be more effectively separated from the surface of the washing space floor. can be done.
In a sixth aspect, in any one of the third to fifth aspects, the tap water that is not electrolyzed water is discharged at a downward discharge angle of 0° or more with respect to the horizontal direction, and the water landing position is It is characterized in that water is jetted so as to move.
According to the sixth invention, it is possible to form water streams that sink between the sebum stain and the surface from various directions, and to more reliably float the sebum stain.

According to the bathroom of the present invention, it is possible to provide a bathroom in which electrolyzed water is easily brought into contact with the surface of the floor of the washing space hidden by sebum stains.

BEST MODE FOR CARRYING OUT THE INVENTION 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 constituent elements in each drawing are denoted by the same reference numerals as much as possible, and overlapping descriptions are omitted.

FIG. 1 is a system block diagram showing the overall configuration of a bathroom washing device 1 according to an embodiment.

The bathroom washing device 1 includes a power source 30 , a control device 40 , an operation section 35 and an electrolyzed water discharge device 100 . The electrolyzed water discharge device 100 is installed on the bathroom counter.

FIG. 2(a) is a schematic perspective view of a bathroom 500 according to the embodiment.
FIG. 2B is an enlarged schematic perspective view of the vicinity of the counter 530 in the bathroom 500. FIG.

As shown in FIG. 2(a), the bathroom 500 is surrounded by four walls 541-544 and a ceiling 545. As shown in FIG. A bathtub 510 , a washing floor 520 and a counter 530 are provided in the bathroom 500 . Furthermore, 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 facing each other on a pair of short sides of the bathtub 510 . 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 facing the fourth wall 544 .

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

On the surface (floor surface) of the floor of the washing area 520, there are the edge on the side of the first wall 541, the edge on the side of the second wall 542, and the edge on the side of the third wall 543 toward the drain port 521. A gentle downward slope (drain slope) is provided.

The counter 530 is attached to the second wall 542, for example. The counter 530 is spaced upward from the surface of the floor 520 of the washroom. The counter 530 has a substantially rectangular shape with long sides along the short sides of the floor 520 when viewed from above.

As shown in FIG. 2B, the counter 530 has a top plate 531 and a cover 532 that covers the top plate 531 below. The electrolyzed water discharge device 100 shown in FIG. 1 is housed inside a counter 530 surrounded by a top plate 531 and a cover 532 except for some elements (a stop cock 50 and a water discharge section 10).

The water discharge part (nozzle part) 10 is provided so as to protrude downward from the counter 530 as shown in FIG. 2(b). The water discharger 10 is separated from the surface of the floor 520 of the washing place. Also, the water discharger 10 is installed near the center of the counter 530 in the width direction (transverse direction). That is, the water discharger 10 is installed near one end in the longitudinal direction of the washing place floor 520 and near the center in the short side direction. At this position, the rotating operation of the water discharger 10, which will be described later, makes it easier to discharge the tap water and the electrolyzed water over substantially the entire floor 520 of the washing place.

A stop cock 50 shown in FIG. 1 is connected to a water supply pipe to which tap water is supplied. The stop cock 50 is connected to a 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 branches into two pipes 61 and 62 .

One pipe 61 is provided with an electromagnetic valve 53 , and the downstream side of the electromagnetic valve 53 is connected to the first water discharge port 11 of the water discharger 10 . In addition, for example, in cold regions, a drain valve 54 is connected between the solenoid valve 53 and the water discharger 10 as necessary.

The other pipe 62 is connected to the strainer 55, the solenoid valve 56, the pressure regulating valve 57, the check valve 59, the electrolyzed water generator 20, the strainer 65, and the second water discharge port 12 of the water discharger 10 in this order from the upstream side. It is A safety valve 58 is connected between the pressure regulating valve 57 and the check valve 59 .

The electrolyzed water discharge device 100 also has a motor (for example, a stepping motor) 66 that rotates (turns) the water discharger 10 . This motor 66 is also housed inside the counter 530 .

The control device 40 controls operations of the solenoid valve 53 , the solenoid valve 56 , the electrolyzed water generator 20 and the motor 66 . A 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 behind the ceiling 545 of the bathroom 500, for example, as shown in FIG. 2(a). 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 spouted from the first spout 11 . When the solenoid valve 53 is closed, tap water is not spouted from the first spout 11 .

The solenoid valve 56 is opened and closed under the control of the controller 40 . When the solenoid valve 56 is opened, tap water is supplied to the electrolyzed water generator 20 , and the electrolyzed water generated by the electrolyzed water generator 20 is discharged from the second water outlet 12 . When the electromagnetic valve 56 is closed, electrolyzed water is not spouted from the second spout 12 .

The tap water pressure control by the pressure regulating valve 57 adjusts the flow rate of the tap water supplied to the electrolyzed water generator 20 . By adjusting the flow rate of tap water supplied to the electrolyzed water generator 20, the flow rate of electrolyzed water spouted from the second water spout 12 is adjusted.

In addition, the solenoid valves 53 and 56 can adjust the flow rate of the tap water supplied downstream.

Electrolyzed water generator 20 generates electrolyzed water. This electrolyzed water is sterilized water having a sterilizing effect. The electrolyzed water generator 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 bacteria and further suppress the growth of bacteria. Therefore, electrolyzed water is sterilized water containing hypochlorous acid and having a sterilizing effect.

FIG. 3 is a perspective view of the water discharger 10. FIG.

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

The first water discharge port 11 and the second water discharge port 12 are arranged side by side in the circumferential direction of the cylindrical water discharge portion 10 . Alternatively, the first water outlet 11 and the second water outlet 12 may be arranged side by side in the height direction.

Tap water that is not electrolyzed water is spouted onto the floor 520 of the washing place from the first spout 11 . The electrolyzed water (disinfected water) described above is spouted onto the floor 520 of the washing place from the second spout 12 . 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 spreads in a fan shape in the vertical direction (vertical direction) can be discharged from the vertically long first water discharge port 11 . Electrolyzed water spreading like a fan in the vertical direction (vertical direction) can be discharged from the vertically long second water discharge port 12 .

By driving the motor 66 described above, the cylindrical water discharger 10 can be rotated around its central axis (indicated by the one-dot chain line in FIG. 3) to change the direction in which tap water or electrolyzed water is discharged. .

The washroom floor 520 has a base material made of FRP (Fiber Reinforced Plastic), for example, and its surface is hydrophilic and oil-repellent.

Here, the oil repellency of the surface of the floor 520 for washing can be defined as follows.
As shown in FIG. 5(a), when the floor 520 of the washroom is held horizontally at room temperature in the atmosphere and a 1 μL oil droplet 300 made of oleic acid is present on the surface, the contact angle of the oil droplet 300 is is 16° or more and 40° or less.

Also, the hydrophilicity of the surface of the floor of the washing space 520 can be defined as a contact angle between water and the surface of the floor of the washing space of 0° or more and 50° or less.

FIG. 4 is a side view schematically showing the trajectory of the electrolyzed water discharged from the water discharger 10 until it lands.

The water discharger 10 can discharge electrolyzed water obliquely toward the floor 520 of the washing place. As described above, the electrolyzed water that is discharged in a fan-like manner in the vertical direction contains a discharge component that has a downward discharge angle of 0° or more and 16° or less with respect to the horizontal direction.

FIG. 4 illustrates trajectories of three lines of electrolyzed water discharged at discharge angles θ1, θ2, and θ3 within the range of 0° or more and 16° or less. The discharge angle of the electrolyzed water discharged in the horizontal direction (the direction along the dashed line in FIG. 4) is 0°.

As with electrolyzed water, the water discharger 10 can discharge tap water that is not electrolyzed water obliquely toward the floor 520 of the washing space. It contains ejection components with an ejection angle of 0° or more and 16° or less.

FIG. 8A is a water discharge time chart of electrolyzed water in the embodiment.

When the user operates the operation unit 35 shown in FIGS. 1 and 2A (when the operation unit 35 is turned ON), the operation unit 35 transmits an execution command for discharging electrolytic water to the control device 40 . After receiving the execution command for discharging electrolyzed water from the operation unit 35, the control device 40 executes control so that the electrolyzed water is discharged from the water discharging unit 10 for the time T1.

According to the embodiment, electrolyzed water can be obliquely discharged toward the surface of the floor 520 of the washing space at a discharge angle sharper (smaller) than the oil contact angle α of the floor 520 of the washing space. The electrolyzed water sharply discharged from such an oblique direction tends to enter between the sebum stain and the surface of the floor 520 of the washing place.

Therefore, it becomes easier for electrolyzed water to come into contact with the surface of the floor 520 of the washing place hidden by sebum stains, and as a result, the surface of the floor 520 of the washing place can be thoroughly sterilized.

The surface of the floor 520 for washing is made hydrophilic, but the oil repellency is not too low (the oil contact angle α is set to 16° or more), and the spreading of sebum stains on the surface is suppressed, so that the sebum stains spread over the surface. You can prevent it from sticking. By discharging the electrolyzed water at a sharp discharge angle (0° or more and 16° or less) equal to or less than the oil contact angle, the electrolyzed water can penetrate between the sebum stain and the surface of the washing place floor 520 .

The electrolyzed water that has entered between the sebum stain and the surface of the washing place floor 520 acts to eliminate bacteria on the surface of the washing place floor 520, and then returns to water, and the sebum stain is discharged as it is to the drain port along with the water. easier. For this reason, an effect unexpected even by a person skilled in the art is produced, in which sebum stains are less likely to come into contact with the surface of the washing space floor 520 that has been sterilized.

A drainage gradient is formed on the surface of the floor 520 of the washing area, and as shown in FIG. 5(b), the surface of the floor 520 of the washing area is inclined. Sebum stains 200 adhering to the surface of the washing space floor 520 whose inclined surface is oil-repellent tend to be inclined in the direction of inclination according to gravity.

In this state, the electrolyzed water enters from below on the inclined surface of the floor 520 of the washing place, with respect to the surface of the floor 520 of the washing place, at a landing angle β of 0° or more and 16° or less (the discharge angle ) to land on the water. As a result, the electrolyzed water can enter between the sebum stain 200 and the surface of the floor 520 of the washing area more effectively.

FIG. 8(b) is a water discharge time chart of tap water and electrolyzed water in the embodiment.

In this example, tap water, which is not electrolyzed water, is discharged diagonally toward the floor 520 of the washing place before electrolyzed water is discharged diagonally toward the floor 520 of the washing space.

When the user operates the operation unit 35 (when the operation unit 35 is turned ON), first tap water, which is not electrolyzed water, is introduced from below on the surface of the floor 520 of the washing floor, which is inclined as shown in FIG. 6(a). The ejection angle is 0° or more and 16° or less. After the operating portion 35 is operated, tap water is discharged from the water discharging portion 10 for a time t1.

After the time t2 has elapsed after the discharge of the tap water is finished, as shown in FIG. Dispense below. The electrolyzed water is discharged during time t3 (=t1).

As a result, the action of separating the sebum stains 200 from the surface of the washing place floor 520 is caused by the tap water, and the action of entering between the sebum stains 200 and the surface of the washing place floor 520 to sterilize the surface of the washing place floor 520 is electrolyzed. can be watered. Therefore, it is possible to prevent the electrolyzed water from contacting the sebum stain 200 unnecessarily in order to separate the sebum stain 200 from the surface of the washing space floor 520, and make the electrolyzed water act on the surface of the washing space floor 520 more effectively. be able to.

Further, the operation unit 35 is operated by the user, and tap water, which is not electrolyzed water, is first discharged at a discharge angle of 0° or more and 16° or less so as to enter from below on the surface of the washing place floor 520, and then for a predetermined time. Neither electrolyzed water nor tap water is discharged until t2 has elapsed. Then, after the predetermined time t2 has passed, the electrolyzed water is discharged at a discharge angle of 0° or more and 16° or less so as to enter from below on the surface of the floor 520 of the washing place.

If the electrolyzed water is discharged to the washing place floor 520 immediately after the tap water lands on the washing place floor 520, the concentration of the sterilizing component of the electrolyzed water will be diluted with the remaining tap water. Therefore, after the tap water is discharged onto the washing place floor 520, the electrolyzed water and the tap water are not discharged until a predetermined time t2 (for example, 30 seconds or more and 1 minute or less) elapses. By discharging water toward the floor 520 of the washing place, the electrolyzed water can be made to act on the surface of the floor 520 of the washing place more effectively.

Further, tap water that is not electrolyzed water is discharged not only to the floor 520 of the washing place but also to the inner wall of the bathroom forming the bathroom. Tap water for separating sebum stains from the surface of the floor 520 of the washing place is intentionally discharged not only to the surface of the floor 520 of the washing place but also to the inner wall of the bathroom forming the bathroom.

As shown in FIG. 7(a), the tap water discharged to the inner wall of the bathroom flows along the downward slope of the surface of the slanted washing floor 520, and the tap water is applied to the sebum stain 200 so as to sandwich the sebum stain 200 from both sides. and the surface of the floor 520 of the washing place, so that the sebum dirt 200 can be more effectively separated from the surface of the floor of the washing place.

Then, after the predetermined time has passed, as shown in FIG. 7B, the electrolyzed water is discharged from below on the surface of the floor 520 for washing at the discharge angle of 0° or more and 16° or less. It is made to enter between the dirt 200 and the surface of the washing place floor 520. - 特許庁

As described above, the water discharger 10 can be rotated around its central axis (indicated by the dashed line in FIG. 3) to change the direction in which tap water or electrolyzed water is discharged. Therefore, the tap water is discharged at a downward discharge angle of 0° or more with respect to the horizontal direction, and is discharged such that the water landing position on the surface of the washing place floor 520 moves.

As a result, it is possible to form water streams that penetrate between the sebum stain and the surface from various directions, and more reliably float the sebum stain.

If the flow velocity of electrolyzed water or tap water discharged from the water discharge unit 10 is slow, the electrolyzed water or tap water lands in a parabola, making it difficult to obtain a landing angle that facilitates entry between sebum stains and the surface of the floor of the washing space. Become. Therefore, for example, the discharge flow rate of electrolyzed water from the water discharger 10 is set to 9 (m/s) or more and 11 (m/s) or less, and the discharge flow rate of tap water from the water discharger 10 is set to 5.6 (m/s). When set, electrolyzed water or tap water is discharged at a downward discharge angle of 0° or more and 40° or less with respect to the horizontal direction, making it easier for the electrolyzed water or tap water to enter between the sebum dirt and the surface of the floor of the washing place.

Also, the electrolyzed water and the tap water are discharged in granular form. 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.
