Description

Aspects of the present invention generally relate to a vanity.

Generally, a wash basin including a wash basin having a bowl portion provided with a drain port and a faucet device having a water discharge portion for discharging water to the bowl portion is known. In addition, a water-related equipment cleaning device equipped with an electrolyzed water generating means for generating functional water having a sterilizing action and an electrolyzed water spraying means for spraying the functional water generated by the electrolytic water generating means to the water-related equipment. It is known (Patent Document 1). According to the water-related equipment cleaning device described in Patent Document 1, it is possible to suppress the growth of bacteria on the surface of the bowl portion.

Almost all of the water flowing on the surface of the bowl of the vanity flows into the drain. Therefore, the drainage port and the inside of the drainage port are most likely to get wet in the bowl part. Since molds and bacteria easily grow in wet areas, many molds and bacteria grow inside the drainage outlet and the drainage outlet. Therefore, it is desirable to discharge the functional water to the drainage port and the inside of the drainage port.

Further, when functional water such as electrolyzed water or ozone water reacts with bacteria, the sterilized component of the sterilized functional water is lost. That is, the concentration of functional water such as electrolyzed water and ozone water decreases when it reacts with bacteria. Here, the landing range of the functional water when the functional water is discharged may be widened on the landing surface due to the momentum of the discharged functional water. When the functional water spreads after landing, it reacts with bacteria over a wide area on the surface of the bowl. As a result, the concentration of functional water may be reduced when it flows inside the drain.

However, when the drain plug of the vanity moves up and down to open and close the drain port, the presence of the drain plug makes it impossible to directly discharge the functional water into the inside of the drain port. Therefore, if the vanity is equipped with a drain plug that moves up and down in the vertical direction (when a drain plug that can open and close the drain port is permanently installed), it is difficult for the functional water to reach the inside of the drain port, and the drain port There is a problem that it is difficult to suppress the growth of mold and the growth of bacteria inside.

As described above, according to the knowledge obtained by the present inventor, when the functional water landed on the bowl portion spreads on the surface of the bowl portion, the surface of the bowl portion can be sterilized, while the inside of the drainage port can be sterilized. Since functional water with reduced sterilizing action flows into the drainage port, it becomes difficult to sterilize the inside of the drainage port. Therefore, there is a problem that it is difficult to suppress the generation of mold and the growth of bacteria inside the drainage port.

Japanese Unexamined Patent Publication No. 10-28721

The present invention has been made based on the recognition of such a problem, and even if a drain plug that can open and close the drain port is permanently installed, even if a large amount of bacteria are attached to the bowl portion, the drain port It is an object of the present invention to provide a vanity table capable of suppressing the growth of mold and the growth of bacteria inside.

The first invention comprises a bowl portion having a drain port and having a drainage gradient inclined downward toward the drain port, a washbasin having a drain plug capable of opening and closing the drain port, and the bowl portion. The functional water discharge device includes a faucet device having a water discharge unit for discharging tap water and a functional water discharge device for discharging functional water having a sterilizing action in the form of a mist. The functional water is landed in a predetermined area near the drain port, the functional water landed in the predetermined area is suppressed from spreading in the bowl portion to form a water film, and the water film is applied to the drainage gradient. It is a vanity table characterized in that the functional water is guided to the inside of the drain port by flowing it to the drain port along the drain port.

Since a large number of bacteria are attached to the bowl portion, the sterilizing action of the functional water directly landed on the bowl portion is lost by the reaction of the functional water with the bacteria on the surface of the bowl portion. Therefore, according to the findings obtained by the inventors, when the functional water landing on the bowl portion spreads along the bowl portion, the surface of the bowl portion is sterilized while the inside of the drainage port is sterilized. It becomes difficult to sterilize the inside of the drainage port because the functional water with reduced action flows.

On the other hand, in the vanity according to the first invention, the functional water discharge device discharges the functional water in the form of a mist toward a predetermined area of the bowl portion. Therefore, the functional water that has landed on the bowl portion becomes water droplets, and over time, the water droplets of the functional water combine with each other and grow into a water film. The functional water that has grown into the water film flows into the inside of the drainage port along the slope of the drainage gradient.

Then, since the functional water is discharged to a predetermined area, the predetermined area is sterilized. Therefore, the functional water will land on the area where the bacteria are dying. Therefore, the functional water flowing into the drainage port gradually flows into the inside of the drainage port with a high sterilizing effect. Therefore, even in a vanity table in which a drain plug is permanently installed on the upper part of the drain port, it is possible to suppress the generation of mold and the growth of bacteria inside the drain port.

A second aspect of the invention is the vanity, wherein the predetermined area includes the entire circumference of the drainage port in the first aspect of the invention.

According to this vanity, the functional water lands on the entire circumference of the drainage port to form a water film and flows inside the drainage port. Therefore, since the functional water is efficiently distributed inside the drainage port, the amount of functional water required for disinfecting the inside of the drainage port can be reduced, and the time for discharging the functional water from the functional water discharge device is shortened. be able to. This makes it possible to save water. Further, when the functional water is electrolyzed water, the energization time of the electrodes can be shortened, and power can be saved. Therefore, the cost of producing functional water can be reduced. In addition, wear of the electrode can be suppressed, and the life of the electrode can be extended.

In the third aspect of the invention, in the second invention, the inclination of the surface of the bowl portion between the landing position of the functional water and the inside of the drainage port is such that the inclination of the surface of the bowl portion is from the landing position to the inside of the drainage port. It is a vanity that is characterized by gradually becoming steeper toward.

The functional water discharged in the form of a mist forms a water film in which water droplets are connected, and utilizes the inclination (drainage gradient) of the surface of the bowl portion between the landing position of the functional water and the inside of the drainage port. It flows toward the inside of the drainage port by its own weight. At this time, the water film is divided by moving on the surface of the bowl portion and becomes smaller, and there is a possibility that the water film will not flow on the surface of the bowl portion even with its own weight. On the other hand, according to the vanity according to the third invention, the inclination of the surface of the bowl portion between the landing position of the functional water and the inside of the drainage port is from the landing position to the inside of the drainage port. The gradual steepness towards, allows the water film to reliably flow inside the drain, even if it becomes smaller.

According to the fourth aspect of the present invention, in the second or third invention, the discharge form of the functional water discharged from the functional water discharge device is a conical discharge water whose inside is filled with the mist-like functional water. It is a characteristic vanity.

According to this vanity, the functional water is discharged in a conical shape from the functional water discharge device. Further, the space inside the functional water discharged in a conical shape is filled with the mist-shaped functional water. That is, the discharge form of the functional water discharged from the functional water discharge device is a conical discharge water. As a result, the drain plug can be sterilized and the generation of mold and the growth of bacteria can be suppressed.

According to the aspect of the present invention, even when a drain plug that can open and close the drain port is permanently installed, even if a large amount of bacteria adhere to the bowl portion, the generation of mold and the propagation of bacteria inside the drain port A vanity that can suppress the problem is provided.

The wash basin 100 according to the present embodiment includes a wash basin 110, a faucet device 120, and a functional water discharge device 130. As shown in FIG. 1, the wash basin 110 is provided, for example, on a cabinet 192. A makeup mirror 191 may be provided on the wash basin 110. The members arranged around the wash basin 110 are not limited to the cabinet 192 and the makeup mirror 191.

In the specification of the present application, the descriptions "upper", "lower", "right" and "left" are based on the person who sees the vanity 100 in front of the vanity 100. And left respectively. Further, in the specification of the present application, the direction from the vanity 100 toward the person in front of the vanity 100 is the "front" direction, and the opposite direction is the "rear" direction.

The wash basin 110 has a bowl portion 111. Further, the wash basin 110 has a drain port 113 (see FIG. 5). The details of the drain port 113 will be described later.

As shown in FIG. 2, the faucet device 120 has a water discharge unit 121. The water discharge unit 121 discharges tap water 167 to the bowl unit 111. Specifically, the faucet device 120 is connected to the water supply source 145 via the branch fitting 142 and the on-off valve 144. The branch fitting 142 is provided, for example, under the bowl portion 111. The tap water 167 is discharged from the water discharge unit 121 to the bowl unit 111 through the on-off valve 144 when the on-off valve 144 is opened by the manual operation of the operation lever 122 which is the operation unit of the faucet device 120. To. In this embodiment, the operation lever 122 and the on-off valve 144 are provided integrally with each other.

The functional water discharge device 130 has an operation unit 131. For example, when the user operates the operation unit 131, the functional water discharge device 130 discharges the functional water 161 having a sterilizing action in the form of mist. The particle size of the mist-like functional water 161 has a distribution, ranging from those on the order of submicrons to those exceeding 2000 micrometers (μm). The average particle size of the mist-like functional water 161 is, for example, about 200 μm or more and 1500 μm or less. As shown in FIG. 2, the functional water discharge device 130 is connected to the water supply source 145 via the branch fitting 142 and the solenoid valve 143. The solenoid valve 143 is provided, for example, under the bowl portion 111. A functional water generation unit 150 is provided between the solenoid valve 143 and the functional water discharge device 130.

The functional water generation unit 150 generates functional water 161 having a sterilizing action. For example, as shown in FIG. 4, the functional water generation unit 150 has an anode 151 and a cathode 152 inside, and the anode 151 and the cathode 152 are generated by an energization control signal output from the control unit 141. The tap water flowing through the space (anode) between the and can be electrolyzed. Tap water contains chloride ions. Chloride ions are contained in water sources (for example, groundwater, dam water, river water, etc.) as, for example, salt (NaCl), calcium chloride (CaCl ₂ ), and the like.

Therefore, when a voltage is supplied between the anode 151 and the cathode 152, the reaction represented by the equation (1) occurs at the cathode 152.

^{H + + e - → 1 /} 2H 2 ↑ ··· (1)

On the other hand, when a voltage is supplied between the anode 151 and the cathode 152, the reactions represented by the formulas (2) and (3) occur at the anode 151.

2OH ⁻ → 2e ⁻ + H ₂ O + 1 / 2O ₂ ↑ ・ ・ ・ (2)
Cl ⁻ → e ⁻ + 1 / 2Cl ₂・ ・ ・ (3)

The chlorine generated in the formula (3) is unlikely to exist as bubbles, and most of the chlorine is dissolved in water. Therefore, with respect to the chlorine generated in the formula (3), the reaction represented by the formula (4) occurs. In this way, hypochlorous acid (HClO) is produced by electrolyzing chloride ions. As a result, the water electrolyzed in the functional water generation unit 150 changes to a liquid containing hypochlorous acid.

_{Cl 2 + H 2 O → HClO} + H + + Cl - ··· (4)

Hypochlorous acid functions as a sterilizing component. The liquid containing hypochlorous acid contains, for example, bacteria adhering to the bowl portion 111, the drain port 113, the inside 116 of the drain port 113, the hair catcher 165 (see FIGS. 9 (a) to 9 (c)), and the like. It can be sterilized.

When the functional water reacts with bacteria, the reaction represented by the formula (5) occurs.

^{R-H + HClO → R-} OH + H + + Cl - ··· (5)

“RH” represented in the formula (5) is an organic substance, for example, a bacterial cell. "R-OH" represented in the formula (5) is a decomposed organic substance. As a result, bacterial cells are denatured and sterilized (sterilized). Then, when the functional water reacts with bacteria, the sterilizing component (HClO) is lost, and as a result, the concentration of the functional water (sterilized water) decreases.

Further, over time, the reaction represented by the formula (6) occurs.

_{^{2HClO → 2H + + 2Cl - +}} O 2 ··· (6)

As described above, over time, the sterilizing component (HClO) is lost, and as a result, the concentration of the functional water (sterilizing water) decreases.

The functional water generation unit 150 of the present embodiment is not limited to producing a liquid containing hypochlorous acid. For example, the functional water 161 generated by the functional water generation unit 150 may be a liquid containing ozone or the like. Further, the functional water generation unit 150 is not limited to the electrolytic cell unit having the anode plate and the cathode plate.

When the control unit 141 transmits a signal to the solenoid valve 143 and opens the solenoid valve 143, the tap water supplied from the water supply source 145 is supplied to the functional water generation unit 150 through the branch fitting 142 and the solenoid valve 143. The tap water supplied to the functional water generation unit 150 is generated as the functional water 161 in the functional water generation unit 150, and is discharged from the functional water discharge device 130 to the bowl unit 111.

For example, as shown in FIG. 3, the functional water discharge device 130 has an operation unit 131, a functional water discharge unit 132, and an irradiation unit 133. For example, when the user operates the operation unit 131, the functional water discharge device 130 discharges the functional water 161 generated by the functional water generation unit 150 from the functional water discharge unit 132 toward the bowl unit 111. The functional water discharge device 130 may emit light from the irradiation unit 133 and irradiate the functional water 161 discharged from the functional water discharge unit 132 with light. The functional water 161 discharged in the form of a mist from the functional water discharge unit 132 lands on a predetermined area in the vicinity of the drain port 113. This will be further described with reference to the drawings.

FIG. 5 is a schematic perspective view showing the vicinity of the bowl portion of the present embodiment.
FIG. 6 is a schematic plan view of the bowl portion of the present embodiment as viewed from above.
FIG. 7 is a schematic cross-sectional view of the cut surface C7-C7 shown in FIG.
FIG. 8 is a schematic cross-sectional view of the cut surface C8-C8 shown in FIG.

As shown in FIGS. 5 to 8, the bowl portion 111 has a drain port 113. As shown in FIGS. 7 and 8, a drainage gradient inclined downward toward the drainage port 113 is formed on the surface 115 of the bowl portion 111. A drain plug 112 is provided on the drain port 113. The drain plug 112 is permanently installed in the portion of the drain port 113, and the drain port 113 can be opened and closed by moving up and down in the vertical direction.

Here, many bacteria are attached to the bowl portion. Therefore, the sterilizing action of the functional water directly landed on the bowl portion is lost by the reaction of the functional water with the bacteria on the surface of the bowl portion. Therefore, according to the findings obtained by the inventors, when the functional water landing on the bowl portion spreads along the bowl portion, the surface of the bowl portion is sterilized while the inside of the drainage port is sterilized. It becomes difficult to sterilize the inside of the drainage port because the functional water with reduced action flows.

On the other hand, in the vanity 100 according to the present embodiment, the functional water discharge device 130 causes the functional water 161 discharged in the form of a mist to land on a predetermined region A1 in the vicinity of the drain port 113. The functional water discharge device 130 forms a water film by suppressing the spread of the functional water 161 that has landed on the predetermined region A1 at the bowl portion 111. Then, the functional water discharge device 130 guides the functional water 161 to the inside 116 of the drainage port 113 (see FIG. 9) by flowing the water film to the drainage port 113 along the drainage gradient of the bowl portion 111. This will be further described with reference to the drawings.

FIG. 9 is a schematic cross-sectional view of the cut surface C9-C9 shown in FIG.
FIG. 9A is a schematic cross-sectional view showing a state immediately after the functional water 161 discharged in the form of a mist from the functional water discharge device 130 has landed on the bowl portion 111. FIG. 9B is a schematic cross-sectional view showing a state in which water droplets are formed from the mist-like functional water 161. FIG. 9C is a schematic cross-sectional view showing a state in which water droplets have grown on a water film.

As shown in FIG. 9A, the functional water discharge device 130 discharges the functional water 161 toward the bowl portion 111 in the form of mist. That is, the functional water discharge device 130 causes the functional water 161 discharged in the form of a mist to land on the predetermined region A1 in the vicinity of the drain port 113.

As shown in FIG. 9B, the functional water 161 that has landed on the bowl portion 111 becomes water droplets 162. As shown in FIG. 9C, in the water droplet 162, the water droplet 162 of the functional water 161 binds to each other over time and grows into the water film 163. The functional water 161 that has grown on the water film 163 flows into the inside 116 of the drain port 113 along the inclined surface of the drainage gradient of the bowl portion 111 by the own weight of the functional water 161 (the own weight of the water film 163).

Then, since the functional water 161 is discharged to the predetermined region A1, the predetermined region A1 is sterilized. Therefore, the functional water 161 will land on the predetermined region A1 where the bacteria are dying. Therefore, the functional water 161 flowing into the inside 116 of the drainage port 113 gradually flows into the inside 116 of the drainage port 113 in a state of having a high sterilizing action. Therefore, it is possible to suppress the generation of mold and the growth of bacteria on the entire edge 114 of the drainage port 113, and even in the vanity 100 in which the drainage plug 112 is permanently installed on the upper part of the drainage port 113. It is possible to suppress the generation of mold and the growth of bacteria in the inside 116 of the drainage port 113.

As described above, the sterilizing action of the functional water (for example, electrolyzed water) is lost by reacting with the bacteria adhering to the discharged object. Therefore, the functional water discharge device 130 has a certain flow rate, water landing range, and discharge time so that the functional water having a concentration of a certain level or more (for example, 1 ppm or more) flows into the inside of the drain port along the drainage gradient. , It is necessary to discharge the functional water 161 in the form of a mist. For example, the functional water discharge device 130 discharges the functional water 161 at a flow rate of 250 cc / min to a landing range having a diameter larger than that of the drain port 113 by 1 cm or more with a discharge time of 10 seconds or more. As a result, functional water having a concentration of a certain level or higher (for example, 1 ppm or higher) can flow into the inside 116 of the drain port 113.

As shown in FIGS. 5 and 6, the predetermined area A1 includes the entire circumference of the drainage port 113. According to this, the functional water 161 lands on the entire circumference of the drainage port 113 to form a water film 163, and flows to the inside 116 of the drainage port 113. Therefore, since the functional water 161 is efficiently distributed to the inside 116 of the drainage port 113, the amount of the functional water 161 required for disinfecting the inside 116 of the drainage port 113 can be reduced, and the functional water from the functional water discharge device 130 can be reduced. The time for discharging 161 can be shortened. This makes it possible to save water. Further, when the functional water 161 is electrolyzed water, in other words, when the functional water generating unit 150 is an electrolytic cell having an electrode as illustrated in FIG. 4, the energization time of the electrode can be shortened. It can save power. Therefore, the cost of producing the functional water 161 can be reduced. In addition, wear of the electrode can be suppressed, and the life of the electrode can be extended.

FIG. 10 is a schematic cross-sectional view of the cut surface C10-C10 shown in FIG. 7.
As shown in FIGS. 7 and 10, the functional water 161 is discharged from the functional water discharge device 130 in a conical shape. The space inside the functional water 161 discharged in a conical shape is filled with the mist-shaped functional water 161. That is, the water discharge form of the functional water 161 discharged from the functional water discharge device 130 is a conical water discharge. As a result, not only the area around the drain port 113 but also the drain plug 112 can be sterilized and cleaned.

FIG. 11 is a schematic cross-sectional view showing a modified example of the bowl portion of the present embodiment.
FIG. 11 corresponds to a schematic cross-sectional view of the cut planes C9-C9 shown in FIG.

The functional water discharged in the form of a mist from the functional water discharge device forms a water film in which water droplets are connected, and the inclination of the surface of the bowl portion between the landing position of the functional water and the inside of the drain port (drainage). It flows toward the inside of the drainage port by its own weight using the gradient). At this time, the water film is divided by moving on the surface of the bowl portion and becomes smaller, and there is a possibility that the water film will not flow on the surface of the bowl portion even with its own weight.

On the other hand, in the bowl portion 111A shown in FIG. 11, the bowl portion 111A between the landing position of the functional water 161 discharged in the form of a mist from the functional water discharge device 130 and the inside 116 of the drain port 113. The inclination of the surface 115A of the surface 115A gradually increases from the landing position of the functional water 161 toward the inside 116 of the drainage port 113.

According to this, the inclination of the surface 115A of the bowl portion 111A between the landing position of the functional water 161 and the inside 116 of the drainage port 113 gradually increases from the landing position toward the inside 116 of the drainage port 113. It's sudden. Therefore, even if the water film 163 becomes small, it can surely flow to the inside 116 of the drain port 113.
