Description

  The present invention relates to a bathroom.

  There is known a sterilizing water discharge device which discharges sterilizing water toward a washing floor of a bathroom (Patent Document 1). In such a sterilizing water discharge device, it is also known to use, for example, electrolyzed water such as hypochlorous acid water generated by electrolyzing flowing water (tap water) as sterilizing water to be discharged. It is done. By using such electrolyzed water as disinfecting water, preparation and replacement of a cartridge etc. which stores detergent etc. is unnecessary compared with the case where, for example, detergent etc. are used, and usability is very good.

  On the other hand, when electrolyzed water such as hypochlorous acid water is used as disinfecting water, for example, the electrolyzed water has the property of being sterilized when it comes in contact with bacteria and returning to water. Therefore, in order to sterilize the surface of the washing floor, it is important that the electrolyzed water be directly applied to the surface of the washing floor.

  However, on the floor of the washing place, sebum dirt and the like washed off from the body of the user of the bathroom often adhere to the surface. Since the surface of the washing floor on which sebum dirt adheres is covered with sebum dirt, the discharged electrolytic water can not directly land. From this, when the user cleans the bathroom with a sponge or brush, for example, to remove sebum dirt, due to bacteria propagated as nutrients with sebum dirt, darkening on the surface of the washing floor from which the sebum dirt has been removed There is a problem that has occurred. That is, even if the electrolytic water is discharged toward the washing floor, there still remains a possibility that darkening may occur on a part of the surface of the washing floor.

  An object of the present invention is to provide a bathroom in which electrolytic water can be easily brought into contact with the surface of the washing floor hidden by sebum dirt.

The bathroom according to the first aspect of the present invention is a bathroom including a washing floor having an oil-repellent surface, and an electrolytic water discharge device capable of discharging electrolytic water having a sterilizing action toward the washing floor, The oil repellency is maintained by keeping the floor of the washing room horizontal at ambient temperature in the air, and an oil contact angle of 40 °, which is the contact angle of the oil droplets when 1 μL of oil droplets of oleic acid are present on the surface. It is the above, It is characterized in that the above-mentioned electrolyzed water discharge device can discharge electrolyzed water diagonally toward the above-mentioned washing floor.
According to the first invention, since the surface of the washing floor is oil-repellent, it is difficult for the surface of the washing floor and sebum dirt to be strongly fixed. By discharging the electrolytic water diagonally toward the surface of the washing floor, it is easy to float sebum dirt on the surface of the washing floor, and the electrolytic water discharged obliquely is more likely to become sebum dirt And it becomes easy to get in between the surface of the washing place and the floor.
Therefore, the electrolyzed water can be easily brought into contact with the portion hidden by the sebum dirt on the surface of the washing floor, and as a result, the surface of the washing floor can be firmly disinfected.
Electrolyzed water that has entered between the sebum dirt and the surface of the washing floor is disinfected to the surface of the washing floor and then returns to the water, and the sebum dirt is easily discharged to the drain with the water as it is. . For this reason, the person skilled in the art also has an unexpected effect that the sebum dirt can not easily come in contact with the surface of the washing floor which has been thoroughly disinfected.
A second invention according to the first invention further comprises an operation unit for discharging the electrolyzed water by the operation of the user, and when the operation unit is operated, the washing water which is not the electrolyzed water is first washed It is characterized in that the electrolytic water is discharged obliquely toward the washing floor after being discharged obliquely toward the floor.
According to the second aspect of the invention, the action of removing sebum dirt from the surface of the washing place floor is tap water, and the action of causing the sebum dirt to enter between the surface of the washing place floor to disinfect the surface of the washing place floor is electrolyzed water It can be made to Therefore, unnecessary contact of electrolyzed water with sebum dirt can be suppressed to separate sebum dirt from the surface of the wash floor, and electrolyzed water can be more effectively applied to the surface of the wash floor.
According to a third invention, in the first invention, when the operation unit is operated, first tap water which is not electrolyzed water is discharged obliquely toward the washing floor, and then the electrolyzed water is kept for a predetermined time. And, without discharging the tap water, after the predetermined time has elapsed, the electrolytic water is discharged obliquely toward the washing floor.
According to the third aspect of the invention, if the electrolytic water is discharged to the washing floor immediately after the tap water is applied to the washing floor, the concentration of the germicidal component of the electrolytic water will be the remaining tap water. It will be diluted. Therefore, after the tap water is discharged to the washing floor, the electrolyzed water and the tap water are not discharged until a predetermined time elapses, and after the predetermined time elapses, the electrolyzed water is discharged toward the washing floor. Effectively, the electrolyzed water can act on the surface of the wash floor.
A fourth invention according to the second or third invention is characterized in that the tap water which is not the electrolyzed water is discharged not only to the washing floor but also to the inner wall of a bathroom forming a bathroom.
According to the fourth aspect of the invention, the tap water can be introduced between the sebum stain and the surface of the washing floor so as to sandwich the sebum dirt from both sides, and the sebum dirt can be more effectively pulled away from the surface of the washing floor Can.

  ADVANTAGE OF THE INVENTION According to the bathroom of this invention, the bathroom which is easy to make electrolyzed water contact the surface of the washing floor hidden from sebum dirt is provided.

  Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. In order to facilitate understanding of the description, the same constituent elements in the drawings are denoted by the same reference numerals as much as possible, and redundant description will be omitted.

  FIG. 1 is a system block diagram showing an entire configuration of a bathroom cleaning apparatus 1 according to the embodiment.

  The bathroom cleaning device 1 includes a power supply 30, a control device 40, an operation unit 35, and an electrolyzed water discharge device 100. The electrolyzed water discharge device 100 is installed at the counter of the bathroom.

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

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

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

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

  From the edge on the first wall 541 side, the edge on the second wall 542 side, and the edge on the third wall 543 side on the surface (floor surface) of the washing floor 520, it is directed to the drainage port 521. A gentle downward slope (drainage slope) is provided.

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

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

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

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

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

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

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

  The controller 40 controls the operation of the solenoid valve 53, the solenoid valve 56, the electrolyzed water generator 20, and the motor 66. The power supply 30 supplies power to them. Also, the power supply 30 supplies power to the operation unit 35. The power supply 30 is installed, for example, behind the ceiling 545 of the bathroom 500 as shown in FIG. 2 (a). The controller 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 controller 40. When the solenoid valve 53 is opened, tap water is spouted from the first spout 11. When the solenoid valve 53 is closed, the tap water is not spouted from the first spout 11.

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

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

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

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

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

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

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

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

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

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

  By driving the motor 66 described above, the cylindrical water discharger 10 is rotated about its central axis (indicated by a dot-and-dash line in FIG. 3A) to change the direction in which tap water or electrolytic water is discharged. be able to.

  FIG. 3 (b) is a schematic cross-sectional view of the washing floor 520.

  The wash floor 520 includes a substrate 521 and a coating 522 formed on the surface of the substrate 521. The substrate 521 may be made of FRP (Fiber Reinforced Plastic), PP (polypropylene) or the like. The coating 522 may have a matrix and a functional material having hydrophilicity and oil repellency dispersed in the matrix.

  The matrix is made of a paint material that reacts with hydroxyl groups, and the functional material is preferably a hydroxyl group-containing fluorine compound. The hydroxyl group of the hydroxyl group-containing fluorine compound exhibits hydrophilicity, and the fluorine exhibits oil repellency. That is, on the surface of the washing floor 520, an oil repellent group 81 and a hydrophilic group 82 are present.

  The surface of the wash floor 520 is both hydrophilic and oil repellent. The oil repellency of the surface of the washing floor 520 here can be defined as follows.

  As shown in FIG. 5 (a), the contact floor angle of the oil drop 300 is maintained when the wash floor 520 is kept horizontal at ambient temperature in the atmosphere and 1 μL of oil drop 300 consisting of oleic acid is present on the surface. The oil contact angle α is 40 ° or more.

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

  The water discharger 10 can discharge electrolytic water diagonally toward the washing floor 520. As described above, the electrolyzed water which is discharged in a fan-like manner in the longitudinal direction includes discharge components having a discharge angle of 0 ° or more and 40 ° or less with respect to the horizontal direction.

  FIG. 4 exemplifies trajectories of three electrolyzed water discharged at discharge angles θ1, θ2, and θ3 as discharge angles within a range of 0 ° or more and 40 ° or less. The discharge angle of the electrolytic water discharged in the horizontal direction (the direction along the broken line in FIG. 4) is 0 °.

  Similar to the electrolyzed water, the water discharger 10 can discharge tap water that is not the electrolyzed water diagonally toward the washing floor 520, and the tap water discharged fan-likely in the vertical direction is directed downward with respect to the horizontal direction. It includes a discharge component having a discharge angle of 0 ° or more and 40 ° or less.

  Fig.8 (a) is a water discharge time chart of the electrolyzed water in embodiment.

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

  According to the embodiment, since the surface of the washing floor 520 is oil-repellent, the surface of the washing floor 520 and sebum dirt are hard to be firmly fixed. By discharging the electrolytic water diagonally toward the surface of the washing floor 520 as described above, the electrolytic water discharged obliquely can be easily floated while making sebum dirt easily float on the surface of the washing floor 520 It becomes easy to get in between the sebum dirt and the surface of the washing floor 520.

  Therefore, the electrolyzed water can be easily brought into contact with the portion hidden by the sebum dirt on the surface of the washing floor 520, and as a result, the surface of the washing floor 520 can be firmly disinfected.

  Electrolyzed water that has entered between the sebum dirt and the surface of the washing floor 520 has the function of disinfecting the surface of the washing floor 520, then returns to the water, and the sebum dirt is discharged with the water as it is to the drainage port. It will be easier. For this reason, the person skilled in the art also has an unexpected effect that the sebum dirt can not easily come in contact with the surface of the washing floor 520 which has been thoroughly disinfected.

  Further, the water discharger 10 can discharge the electrolyzed water at a discharge angle (0 ° or more and 40 ° or less) sharper (smaller) than the oil contact angle of the washing floor 520. Electrolyzed water thus discharged sharply and sharply is more likely to enter between the sebum dirt that has become easy to float and the surface of the washing floor 520.

  A drainage gradient is formed on the surface of the washing floor 520, and as shown in FIG. 5 (b), the surface of the washing floor 520 is inclined. The sebum dirt 200 attached to the surface of the washing floor 520 where the inclined surface is oil-repellent tends to be inclined in the inclination direction according to gravity.

  In such a state, the electrolyzed water enters the surface of the wash floor 520 from the lower side so that the water contact angle β (the discharge angle is 0 ° or more and 40 ° or less) with respect to the surface of the wash floor 520 And the water is discharged so as to land in water. This allows the electrolyzed water to be more effectively introduced between the sebum stain 200 and the surface of the washing floor 520.

  Drawing 8 (b) is a spout time chart of tap water and electrolysis water in an embodiment.

  In this example, before the electrolytic water is discharged obliquely toward the washing floor 520, tap water which is not the electrolytic water is discharged obliquely to the washing floor 520.

  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 at the surface of the inclined washing floor 520 as shown in FIG. The above discharge angle is 0 ° or more and 40 ° or less. After the operation of the operation unit 35, tap water is first discharged from the water discharger 10 for a time t1.

  After the discharge of tap water, after time t2, as shown in FIG. 6 (b), the above-mentioned discharge angle is 0 ° or more and 40 ° so that the electrolyzed water enters from the lower side on the surface of the washing floor 520. Eject with the following. Electrolyzed water is discharged for time t3 (= t1).

  As a result, the action of removing sebum soil 200 from the surface of washing floor 520 is tap water, and the action of causing sebum dirt 200 and the surface of washing floor 520 to disinfect the surface of washing floor 520 is electrolyzed. It can be made water. Therefore, unnecessary contact of electrolytic water with sebum stain 200 can be suppressed in order to separate sebum stain 200 from the surface of washroom floor 520, and the electrolytic water can be more effectively applied to the surface of washroom floor 520. be able to.

  In addition, after the operation unit 35 is operated by the user and the tap water which is not the electrolyzed water is first discharged from below at the surface of the washing floor 520 at a discharge angle of 0 ° or more and 40 ° or less, the predetermined time Neither the electrolyzed water nor the tap water is discharged until t2 elapses. Then, after a predetermined time t 2 elapses, the electrolytic water is discharged at a discharge angle of 0 ° or more and 40 ° or less so as to enter from the lower side on the surface of the washing floor 520.

  If the electrolyzed water is discharged to the washing floor 520 immediately after the tap water is applied to the washing floor 520, the concentration of the germicidal component of the electrolyzed water will be diluted with the remaining tap water. Therefore, after the tap water is discharged to the washing 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, and after the predetermined time t2 elapses, the electrolysis is performed. By discharging the water toward the washing floor 520, the electrolyzed water can be more effectively applied to the surface of the washing floor 520.

  In addition, tap water which is not electrolyzed water is discharged not only to the washing floor 520 but also to the inner wall of the bathroom forming the bathroom. The tap water for removing sebum dirt from the surface of the washing floor 520 is discharged not only to the surface of the washing floor 520 but also to the inner wall of the bathroom forming the bathroom.

  The tap water discharged to the inner wall of the bathroom flows along the downward slope of the surface of the inclined washing floor 520, as shown in FIG. 7A, and the tap water is sebum-contaminated 200 so as to be pinched from both sides of the sebum stain 200. And the surface of the washing floor 520, and the sebum dirt 200 can be more effectively pulled away from the surface of the washing floor.

  Then, after the predetermined time has elapsed, as shown in FIG. 7B, the electrolyzed water is discharged at the discharge angle of 0 ° or more and 40 ° or less so as to enter from below on the surface of the washing floor 520, sebum It gets in between the dirt 200 and the surface of the washing floor 520.

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

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

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