Description

[Technical field]

[0001] The present invention relates to a bathroom. [Background technology]

[0002] A disinfectant water discharge device that discharges disinfectant water toward the bathroom washing floor is known (Patent Document 1). In such a disinfectant water discharge device, it is also known that electrolytic water such as hypochlorous acid water generated by electrolyzing flowing water (tap water) is used as the disinfectant water to be discharged. By using such electrolytic water as disinfectant water, it is not necessary to prepare or replace cartridges for storing detergent, etc., compared to using detergent, etc., and it is very easy to use.

[0003] On the other hand, when electrolyzed water such as hypochlorous acid water is used as disinfectant water, the electrolyzed water has the property of sterilizing bacteria when it comes into contact with them and then turning back into water. Therefore, in order to disinfect the surface of the washing area floor, it is essential to apply the electrolyzed water directly to the surface of the washing area floor.

[0004] [Patent Document 1] JP 2009-178470 A [Patent Document 2] Patent No. 5371337 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the washing floor often has sebum dirt and the like that has been washed off from the body of the bathroom user attached to the surface. In particular, if the surface of the washing floor is made hydrophilic to improve drainage, the sebum also tends to spread widely on the surface, so that the sebum dirt and the like tends to adhere widely to the surface. The surface of the washing floor with sebum dirt attached is covered with sebum dirt, so the discharged electrolytic water cannot land directly on it. For this reason, when a user cleans the bathroom with, for example, a sponge or brush to remove the sebum dirt, there is a problem that the surface of the washing floor from which the sebum dirt has been removed becomes blackened due to bacteria that grow using the sebum dirt as nutrients. In other words, even if the electrolytic water is discharged toward the washing floor, there is still a possibility that some of the surface of the washing floor will become blackened.

[0006] To provide a bathroom in which electrolytic water can be easily brought into contact with the surface of a washing area floor covered with sebum stains. [Means for solving the problem]

[0007] The bathroom of the first invention is a bathroom equipped with an electrolyzed water discharge device capable of discharging electrolyzed water having a disinfecting effect toward a washing area floor, and the surface of the washing area floor is characterized in that when the washing area floor is held horizontally at room temperature in the air and a 1 μL oil droplet of oleic acid is placed on the surface, the oil contact angle is 16° or more, and the downward discharge angle of the electrolyzed water from the electrolyzed water discharge device relative to the horizontal direction is 0° or more and 16° or less. According to the first invention, electrolytic water can be discharged obliquely toward the surface of the washing area floor at a discharge angle sharper than the oil contact angle of the washing area floor. Such electrolytic water discharged sharply obliquely is likely to get between the sebum dirt and the surface of the washing area floor 520. Therefore, it becomes easier for the electrolytic water to come into contact with the part of the surface of the washing area floor hidden by the sebum dirt, and as a result, the surface of the washing area floor can be thoroughly disinfected. The surface of the washing area floor is made hydrophilic while not becoming too oil repellent (oil contact angle α is set to 16° or more), and the spread of sebum dirt on the surface is suppressed, so that the sebum dirt does not adhere widely to the surface. By discharging electrolytic water at a sharp discharge angle (0° or more and 16° or less) equal to or less than the oil contact angle, the electrolytic water can be made to penetrate between the sebum dirt and the surface of the washing area floor. The electrolytic water that gets between the sebum dirt and the surface of the washing area floor disinfects the surface of the washing area floor, then turns back into water, and the sebum dirt is easily discharged into the drain along with the water. This has resulted in an unexpected effect, even for those skilled in the art, of making it difficult for sebum dirt to come into contact with the surface of the washing area floor that has been disinfected. The second invention is characterized in that, in the first invention, the surface of the washing area floor is inclined, and the electrolyzed water discharge device discharges the electrolyzed water so that the water enters from below the inclined surface of the washing area floor and hits the surface of the washing area floor at a water landing angle of 0° or more and 16° or less. According to the second invention, the sebum dirt adhering to the surface of the inclined washing area floor is likely to be tilted in the inclined direction due to gravity. In this state, the electrolytic water is discharged so that it enters the surface of the inclined washing area floor from below and lands at an angle of 0° or more and 16° or less with respect to the surface of the washing area floor. This makes it possible to more effectively allow the electrolytic water to enter between the sebum dirt and the surface of the washing area floor. The third invention is characterized in that, in the second invention, the device further includes an operating unit that is operated by a user to discharge electrolyzed water, and when the operating unit is operated, tap water that is not electrolyzed water is first discharged at a downward discharge angle of 0° or more and 16° or less relative to the horizontal direction so that it enters from below onto the surface of the inclined washing area floor, and then electrolyzed water is discharged at a downward discharge angle of 0° or more and 16° or less relative to the horizontal direction so that it enters from below onto the surface of the inclined washing area floor. According to the third invention, the action of separating sebum dirt from the surface of the washing place floor can be made to be tap water, and the action of sterilizing the surface of the washing place floor by penetrating between the sebum dirt and the surface of the washing place floor can be made to be electrolytic water. Therefore, it is possible to suppress the electrolytic water from coming into contact with the sebum dirt unnecessarily in order to separate the sebum dirt from the surface of the washing place floor, and the electrolytic water can be more effectively applied to the surface of the washing place floor. The fourth invention is characterized in that, in the third invention, when the operating unit is operated, tap water that is not electrolyzed water is first ejected at a downward ejection angle of 0° or more and 16° or less relative to the horizontal direction so that it enters from below onto the surface of the inclined washing area floor, and then the electrolyzed water and tap water are not ejected until a predetermined time has elapsed, and after the predetermined time has elapsed, the electrolyzed water is ejected at a downward ejection angle of 0° or more and 16° or less relative to the horizontal direction so that it enters from below onto the surface of the inclined washing area floor. According to the fourth invention, if electrolytic water is discharged onto the washing area floor immediately after tap water is applied to the washing area floor, the concentration of the disinfecting component of the electrolytic water will be diluted by the remaining tap water. Therefore, after the tap water is discharged onto the washing area floor, the electrolytic water and tap water are not discharged until a predetermined time has passed, and after the predetermined time has passed, the electrolytic water is discharged toward the washing area floor, so that the electrolytic water can be more effectively applied to the surface of the washing area floor. The fifth invention is characterized in that, in the third or fourth invention, the tap water that is not electrolyzed water is ejected not only onto the washing area floor, but also onto the inner walls of the bathroom that form the bathroom. According to the fifth invention, tap water can be allowed to penetrate between the sebum stains and the surface of the washing area floor, so as to sandwich the sebum stains from both sides, thereby more effectively separating the sebum stains from the surface of the washing area floor. The sixth invention is characterized in that, in any one of the third to fifth inventions, the tap water that is not electrolyzed water is discharged at a downward discharge angle of 0° or more relative to the horizontal direction and is ejected so that the landing position moves. According to the sixth aspect of the present invention, a water flow can be formed that penetrates between the sebum stain and the surface from various directions, making it possible to more reliably lift off the sebum stain. Effect of the Invention

[0008] According to the bathroom of the present invention, a bathroom is provided in which electrolytic water can easily come into contact with the surface of the washing area floor hidden by sebum stains. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In order to facilitate understanding of the description, the same reference numerals are used to refer to the same components in each drawing as much as possible, and duplicated description will be omitted.

[0011] FIG. 1 is a system block diagram showing the overall configuration of a bathroom cleaning device 1 according to an embodiment.

[0012] Bathroom cleaning device 1 comprises a power source 30, a control device 40, an operation unit 35, and electrolyzed water discharge device 100. Electrolyzed water discharge device 100 is installed on the counter of the bathroom.

[0013] FIG. 2(a) is a schematic oblique view of a bathroom 500 according to an embodiment. FIG. 2(b) is a schematic perspective view showing an enlarged view of the vicinity of the counter 530 in the bathroom 500.

[0014] As shown in Fig. 2(a), bathroom 500 is surrounded by four walls 541-544 and a ceiling 545. Provided within bathroom 500 are a bathtub 510, a washing area floor 520, and a counter 530. Furthermore, bathroom 500 is provided with a mirror, a water faucet, a hand shower, and the like as appropriate.

[0015] A first wall 541 and a second wall 542 are provided facing each other on a pair of short sides of bathtub 510. A fourth wall 544 is provided on one long side of bathtub 510. A third wall 543 is provided facing fourth wall 544 on the washing area floor 520 side.

[0016] A drain outlet 521 is provided in the washing area floor 520. In the example shown in Fig. 2(a), the drain outlet 521 is located near the edge of the washing area floor 520 on the bathtub 510 side, and approximately in the center of the washing area floor 520 in the longitudinal direction.

[0017] The surface (floor surface) of the washing area floor 520 has a gentle downward slope (drainage gradient) 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 drain outlet 521.

[0018] Counter 530 is attached to, for example, second wall 542. Counter 530 is installed at a distance above the surface of washing area floor 520. When viewed from above, counter 530 has a substantially rectangular shape with a long side aligned with the short side direction of washing area floor 520.

[0019] As shown in Fig. 2(b), the counter 530 has a top plate 531 and a cover 532 that covers the bottom of the top plate 531. The electrolyzed water discharge device 100 shown in Fig. 1 is housed inside the counter 530 surrounded by the top plate 531 and the cover 532, except for some elements (stop valve 50, water discharge unit 10).

[0020] As shown in FIG. 2(b), the water discharger (nozzle portion) 10 is provided so as to protrude below the counter 530. The water discharger 10 is spaced apart from the surface of the washing area floor 520. The water discharger 10 is also installed near the center of the width direction (short side direction) of the counter 530. In other words, the water discharger 10 is installed on one end side of the washing area floor 520 in the longitudinal direction and near the center in the short side direction. The rotational movement of the water discharger 10 described later in this position makes it easier to discharge tap water and electrolytic water over substantially the entire washing area floor 520.

[0021] 1 is connected to a water supply pipe through which tap water is supplied. The stop valve 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.

[0022] 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 outlet 10. In addition, for example in cold regions, a drain valve 54 is connected between the solenoid valve 53 and the water outlet 10 as necessary.

[0023] The other pipe 62 is connected to, in order from the upstream side, a strainer 55, a solenoid valve 56, a pressure adjusting valve 57, a check valve 59, the electrolytic water generating unit 20, the strainer 65, and the second water outlet 12 of the water outlet unit 10. In addition, a safety valve 58 is connected between the pressure adjusting valve 57 and the check valve 59.

[0024] The electrolytic 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.

[0025] Control device 40 controls the operation of solenoid valve 53, solenoid valve 56, electrolyzed water generator 20, and motor 66. Power source 30 supplies them with power. Power source 30 also supplies power to operation unit 35. Power source 30 is installed, for example, behind ceiling 545 of bathroom 500 as shown in FIG. 2(a). Control device 40 is installed inside counter 530 or behind ceiling 545 of bathroom 500.

[0026] The solenoid valve 53 is opened and closed under the control of the control device 40. When the solenoid valve 53 is open, tap water is discharged from the first water outlet 11. When the solenoid valve 53 is closed, tap water is not discharged from the first water outlet 11.

[0027] 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 electrolytic water generator 20, and the electrolytic water generated in the electrolytic water generator 20 is discharged from the second water outlet 12. When the solenoid valve 56 is closed, the electrolytic water is not discharged from the second water outlet 12.

[0028] The flow rate of tap water supplied to the electrolytic water generator 20 is adjusted by controlling the pressure of the tap water by the pressure regulating valve 57. The flow rate of the electrolytic water discharged from the second water outlet 12 is adjusted by adjusting the flow rate of the tap water supplied to the electrolytic water generator 20.

[0029] In addition, the flow rate of tap water supplied to the downstream side can be adjusted by the solenoid valves 53 and 56.

[0030] The electrolytic water generating unit 20 generates electrolytic water. This electrolytic water is sterilizing water that has a sterilizing effect. The electrolytic 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 and electrolyzing the tap water flowing between the anode and the cathode, the tap water is transformed into electrolytic water. Since the tap water contains chloride ions, hypochlorous acid is generated by electrolyzing the chloride ions.

[0031] Hypochlorous acid has the ability to kill bacteria and further suppress the growth of bacteria. Therefore, electrolyzed water is a disinfecting water that contains hypochlorous acid and has a disinfecting effect.

[0032] FIG. 3 is a perspective view of the water discharger 10. As shown in FIG.

[0033] The water spouting part 10 is formed in a cylindrical shape, and a first water spouting outlet 11 and a second water spouting outlet 12 are provided on the lower side surface thereof. The first water spouting outlet 11 and the second water spouting outlet 12 are each formed in the shape of a vertically long slit.

[0034] The first water outlet 11 and the second water outlet 12 are arranged side by side in the circumferential direction of the cylindrical water outlet part 10. Alternatively, the first water outlet 11 and the second water outlet 12 may be arranged side by side in the height direction.

[0035] From the first water outlet 11, tap water that is not electrolyzed water is discharged onto the washing area floor 520. From the second water outlet 12, the above-mentioned electrolyzed water (sterilized water) is discharged onto the washing area floor 520. Tap water or electrolyzed water can be temporarily stored inside the cylindrical water discharge unit 10, and the water discharge pressure can be increased.

[0036] Tap water can be discharged in a fan shape in the vertical direction (up and down direction) from the vertically long first water outlet 11. Electrolyzed water can be discharged in a fan shape in the vertical direction (up and down direction) from the similarly long second water outlet 12.

[0037] By driving the aforementioned motor 66, the cylindrical water discharger 10 can be rotated about its central axis (shown by the dashed line in FIG. 3) to change the direction in which tap water or electrolyzed water is discharged.

[0038] The washing area floor 520 has a base material made of, for example, FRP (Fiber Reinforced Plastic), and its surface is hydrophilic and oil-repellent.

[0039] The oil repellency of the surface of the washing area floor 520 here can be defined as follows. As shown in FIG. 5(a), when a washing area floor 520 is held horizontally in the air at room temperature and a 1 μL oil droplet 300 made of oleic acid is placed on its surface, the oil contact angle α of the oil droplet 300 is 16° or more and 40° or less.

[0040] In addition, the hydrophilicity of the surface of the washing area floor 520 can be defined as the contact angle between water and the surface of the washing area floor 520 being 0° or more and 50° or less.

[0041] FIG. 4 is a side view that shows a schematic trajectory of electrolytic water discharged from water discharger 10 until it lands on the water.

[0042] The water discharger 10 can discharge the electrolytic water obliquely toward the washing area floor 520. As described above, the electrolytic water discharged in a fan-like manner in the vertical direction contains discharge components whose downward discharge angle with respect to the horizontal direction is 0° or more and 16° or less.

[0043] 4 shows three trajectories of electrolytic water discharged at discharge angles θ1, θ2, and θ3, which are in the range of 0° or more and 16° or less. The discharge angle of electrolytic water discharged in the horizontal direction (the direction along the dashed line in FIG. 4) is 0°.

[0044] Similar to electrolyzed water, the water discharge section 10 can discharge non-electrolyzed tap water at an angle toward the washing area floor 520, and the tap water discharged in a fan-like shape in the vertical direction contains a discharge component whose downward discharge angle with respect to the horizontal direction is greater than or equal to 0° and less than or equal to 16°.

[0045] FIG. 8(a) is a time chart showing the discharge of electrolytic water in the embodiment.

[0046] 1 and 2(a) (when the operation unit 35 is turned ON), the operation unit 35 transmits a command to discharge electrolytic water to the control device 40. After receiving the command to discharge electrolytic water from the operation unit 35, the control device 40 executes control so that electrolytic water is discharged from the water discharger 10 for a time T1.

[0047] According to the embodiment, the electrolytic water can be discharged obliquely toward the surface of the washing place floor 520 at a discharge angle sharper (smaller) than the oil contact angle α of the washing place floor 520. Such electrolytic water discharged sharply obliquely is likely to get between the sebum dirt and the surface of the washing place floor 520.

[0048] Therefore, it becomes easier for the electrolytic water to come into contact with the parts of the surface of the washing area floor 520 that are hidden by sebum stains, and as a result, the surface of the washing area floor 520 can be thoroughly disinfected.

[0049] The surface of the washing area floor 520 is made hydrophilic while not becoming too oil repellent (oil contact angle α is set to 16° or more), and the spread of sebum dirt on the surface is suppressed, so that the sebum dirt does not adhere widely to the surface. By discharging the electrolytic water at a sharp discharge angle (0° or more and 16° or less) equal to or less than the oil contact angle, the electrolytic water can be made to penetrate between the sebum dirt and the surface of the washing area floor 520.

[0050] The electrolytic water that has penetrated between the sebum dirt and the surface of the washing area floor 520 disinfects the surface of the washing area floor 520 and then returns to water, and the sebum dirt is easily discharged together with the water into the drain. This has resulted in an unexpected effect, even for those skilled in the art, that it makes it difficult for sebum dirt to come into contact with the surface of the washing area floor 520 that has been disinfected.

[0051] A drainage gradient is formed on the surface of the washing area floor 520, and as shown in Fig. 5(b), the surface of the washing area floor 520 is inclined. The sebum stain 200 adhering to the surface of the washing area floor 520, which has an inclined surface that is oil-repellent, tends to be inclined in the inclined direction due to gravity.

[0052] In this state, the electrolytic water is discharged so that it enters from below the surface of the inclined washing place floor 520 at a water landing angle β (which is in a relationship of an angle opposite to the above discharge angle) of 0° or more and 16° or less with respect to the surface of the washing place floor 520. This makes it possible to more effectively allow the electrolytic water to enter between the sebum dirt 200 and the surface of the washing place floor 520.

[0053] FIG. 8(b) is a time chart showing the discharge of tap water and electrolytic water in the embodiment.

[0054] In this example, before electrolytic water is discharged obliquely toward the washing area floor 520, tap water that is not electrolytic water is discharged obliquely toward the washing area floor 520.

[0055] When the user operates the operation unit 35 (when the operation unit 35 is turned ON), tap water that is not electrolyzed water is first discharged at the above-mentioned discharge angle of 0° or more and 16° or less so that it enters from below onto the surface of the inclined washing area floor 520 as shown in Fig. 6(a). After the operation of the operation unit 35, tap water is first discharged from the water discharge unit 10 for a time t1.

[0056] After the end of the tap water discharge and the passage of time t2, as shown in Fig. 6(b), electrolytic water is discharged at the discharge angle of 0° or more and 16° or less so as to enter from below on the surface of the washing area floor 520. The electrolytic water is discharged for a time t3 (=t1).

[0057] This allows tap water to act to separate the sebum dirt 200 from the surface of the washing place floor 520, and allows electrolytic water to penetrate between the sebum dirt 200 and the surface of the washing place floor 520 to disinfect the surface of the washing place floor 520. Therefore, it is possible to prevent the electrolytic water from contacting the sebum dirt 200 unnecessarily in order to separate the sebum dirt 200 from the surface of the washing place floor 520, and the electrolytic water can be more effectively applied to the surface of the washing place floor 520.

[0058] In addition, the operating unit 35 is operated by the user, and tap water other than electrolyzed water is discharged at a discharge angle of 0° or more and 16° or less so that it enters from below on the surface of the washing area floor 520, and then neither electrolyzed water nor tap water is discharged until a predetermined time t2 has elapsed. Then, after the predetermined time t2 has elapsed, electrolyzed water is discharged at a discharge angle of 0° or more and 16° or less so that it enters from below on the surface of the washing area floor 520.

[0059] If electrolytic water is discharged onto the washing area floor 520 immediately after tap water is landed on the washing area floor 520, the concentration of the antibacterial component of the electrolytic water will be diluted by the remaining tap water. Therefore, after the tap water is discharged onto the washing area floor 520, the electrolytic water and tap water are not discharged until a predetermined time t2 (for example, 30 seconds or more and 1 minute or less) has passed, and after the predetermined time t2 has passed, the electrolytic water is discharged toward the washing area floor 520, so that the electrolytic water can act more effectively on the surface of the washing area floor 520.

[0060] In addition, tap water that is not electrolyzed water is discharged not only onto the washing area floor 520 but also onto the bathroom interior walls that form the bathroom. Tap water for removing sebum dirt from the surface of the washing area floor 520 is discharged not only onto the surface of the washing area floor 520 but also onto the bathroom interior walls that form the bathroom.

[0061] As shown in Figure 7(a), tap water discharged onto the bathroom interior wall flows along the downward slope of the surface of the inclined washing area floor 520, allowing the tap water to penetrate between the sebum stain 200 and the surface of the washing area floor 520, sandwiching the sebum stain 200 from both sides, thereby more effectively separating the sebum stain 200 from the surface of the washing area floor.

[0062] Then, after the above-mentioned specified time has elapsed, as shown in Figure 7 (b), the electrolyzed water is ejected at the above-mentioned ejection angle of 0° or more and 16° or less so that the electrolyzed water penetrates from below onto the surface of the washing area floor 520, and penetrates between the sebum stains 200 and the surface of the washing area floor 520.

[0063] As described above, the water discharger 10 can be rotated around its central axis (shown by a dashed line in FIG. 3) to change the direction in which tap water or electrolytic water is discharged. Therefore, tap water is discharged so that the landing position on the surface of the washing area floor 520 moves when the tap water is discharged at a downward discharge angle of 0° or more relative to the horizontal direction.

[0064] This allows the formation of water currents that penetrate between the sebum stains and the surface from various directions, making it possible to more reliably lift off the sebum stains.

[0065] If the discharge flow rate of the electrolytic water or tap water from the water discharge unit 10 is slow, the electrolytic water or tap water will land in a parabolic arc, making it difficult to obtain a landing angle that allows the water to easily get between the sebum dirt and the surface of the washing area floor. Therefore, for example, if the discharge flow rate of the electrolytic water from the water discharge unit 10 is set to 9 (m / s) or more and 11 (m / s) or less, and the discharge flow rate of the tap water from the water discharge unit 10 is set to 5.6 (m / s), the electrolytic water or tap water will be discharged at a downward discharge angle of 0° or more and 40° or less relative to the horizontal direction, making it easier for the electrolytic water or tap water to get between the sebum dirt and the surface of the washing area floor.

[0066] The electrolytic water and tap water are each discharged in the form of particles. For example, the particle size of the electrolytic water is 800 μm, and the particle size of the tap water is 0.3 mm to 3.5 mm.

[0067] Although the embodiments of the present invention have been described above with reference to specific examples, the present invention is not limited thereto, and various modifications are possible based on the technical concept of the present invention. [Explanation of symbols]
