  Disinfecting the sterilized water into the sink as in the prior art described above enables sterilization of cooking utensils, foodstuffs, sinks, drainage baskets, and the like. However, sterilized water that jumped during cleaning tends to accumulate, and the root portion of the faucet, which is difficult to clean, is not directly exposed to sterilized water, so that sterilization by discharging the sterilized water is difficult. In order to sterilize using the sterilized water, for example, a method of providing a sterilized water discharge unit with a hose and directly discharging the sterilized water toward the root portion of the faucet is also conceivable. However, since the root portion of the faucet is provided at a high position outside the sink or inside the sink, there arises a specific problem that a large amount of sterilized water is scattered outside the sink.

  This invention is made | formed in view of such a subject, The objective is to provide the water discharging apparatus which can supply disinfection water to the root part of a faucet, without scattering outside a sink. .

  In order to solve the above problems, a water discharge device according to the present invention is a water discharge device provided in a kitchen, and includes a mounting portion attached to the kitchen, a spout portion extending upward from the mounting portion, A sterilizing water generating unit that generates sterilizing water; and a sterilizing water discharging unit that is provided in the spout unit and discharges the sterilizing water generated by the sterilizing water generating unit toward a sink of a kitchen. A first water discharge state in which the sterilized water discharged from the sterilized water discharge unit is discharged into the sink, and the sterilized water discharged from the sterilized water discharge unit is supplied to the attachment unit. Two water discharge states can be formed. In the second water discharge state, the sterilized water discharged from the sterilized water discharge part flows along the outer surface of the spout part, and the sterilized water flowing along the outer surface of the spout part is attached to the second water discharge state. Guide to the part.

  In this invention, since it has comprised so that disinfection water can be discharged toward the inside of a sink, cooking utensils, such as a cutting board and a kitchen knife, can be disinfected, or a sink main body and a drain outlet can be disinfected. In addition, by realizing the second water discharge state in which the sterilized water is guided to the attachment portion along the outer surface of the spout portion, the pin can flow slowly with respect to the attachment portion which is the base portion of the faucet and the pin Sterile water can be supplied at points. Thus, the sterilized water can be supplied to the base portion of the faucet without being scattered outside the sink.

  Moreover, in the water discharging apparatus which concerns on this invention, it is also preferable that the said 2nd water discharging state is comprised so that it may be automatically performed after performing the said 1st water discharging state.

  After the first water discharge state, dirty water splashed when sterilizing cooking utensils such as cutting boards and kitchen knives is likely to accumulate in the mounting portion, and if this water is left for a long period of time, bacteria will propagate. Therefore, in this preferred embodiment, since the second water discharge state is automatically executed after the first water discharge state, even if dirty water stays in the mounting portion during the first water discharge state, the second water discharge state immediately The water staying in the mounting portion can be replaced with the sterilized water. Thereby, it can prevent more reliably that bacteria propagate in an attaching part.

  Moreover, in the water discharging apparatus which concerns on this invention, it is also preferable that the said 2nd water discharging state is formed by discharging the sterilization water of a flow volume smaller than the said 1st water discharging state.

  In this preferred embodiment, when the flow rate is lowered, the water flows along the spout portion, and the second water discharge state can be formed by reducing the flow rate. Therefore, the direction of the sterilized water discharge portion is changed. The second water discharge state can be formed by a simple method without using the complicated structure.

  Moreover, in the water discharging apparatus which concerns on this invention, it is also preferable that the operation part which switches the water discharge and the water stop of the sterilization water from the said sterilization water discharge part is provided in the said attachment part.

  In this preferred embodiment, an operation part that is often touched with a dirty hand is provided on the attachment part, so that an operation part where bacteria can easily propagate can be sterilized at the same time.

  According to the present invention, the present invention has been made in view of such a problem, and the object thereof is a water discharger capable of supplying sterilized water to the root portion of the faucet without splashing outside the sink. Can be provided.

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

  A water discharger according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a perspective view showing an external appearance of a water discharging apparatus according to an embodiment of the present invention. FIG. 2 is a front view showing an appearance of the water discharging device according to the embodiment of the present invention. FIG. 3 is a plan view showing an appearance of the water discharging device according to the embodiment of the present invention.

  As shown in FIG. 1, the water discharge device WD is provided in the sink SK. The water discharge device WD includes a tap water discharge unit 10 and a sterilized water discharge unit 20.

  As shown in FIG. 2, the tap water discharge unit 10 includes a spout unit 101, an attachment unit 102, and an operation unit 103. The sterilized water discharge unit 20 includes a spout unit 201, an attachment unit 202, and an operation unit 203.

  As shown in FIG. 3, the sink SK includes a bottom surface SK1 and a drain port SK2. The drain port SK2 is provided at one end in the width direction of the sink SK. The bottom surface SK1 has a water gradient so that water flows toward the drain port SK2. The disinfecting water discharge unit 20 is disposed opposite to the drain outlet SK2, and is provided at the other end in the width direction of the sink SK. The tap water discharge part 10 is arrange | positioned near the center.

  Next, the flow path configuration of the water discharge device WD will be described with reference to FIG. In FIG. 4, the flow-path structure by the side of the disinfection water discharge part 20 of the water discharging apparatus WD is shown. As shown in FIG. 4, a sterilized water generating unit 30 is connected to the sterilized water discharging unit 20, and the sterilized water generating unit 30 supplies the sterilized water.

  The sterilized water generator 30 includes a stop cock 31, a solenoid valve 32, a pressure regulating valve 33, a check valve 34, an electrolytic cell 35, a salt water pack 36, a micropump 37, a control device 38, It has. From the upstream side, the piping path is connected to the stop cock 31, the electromagnetic valve 32, the pressure regulating valve 33, the check valve 34, and the electrolytic bath 35, and finally connected to the sterilized water discharge unit 20. The salt water pack 36 and the micro pump 37 are provided as a side flow path, are connected from the salt water pack 36 to the micro pump, and are connected to the piping path upstream of the electrolytic cell 35. The control device 38 outputs a control signal to each of the electromagnetic valve 32, the electrolytic cell 35, and the micropump 37. The electromagnetic valve 32 opens and closes the valve so as to discharge and stop water in response to a control signal output from the control device 38. The electrolytic cell 35 is provided with a pair of electrodes, and the energization state of the pair of electrodes is varied in accordance with a control signal output from the control device 38. When the pair of electrodes are energized, sterilized water is generated in the electrolytic bath 35 and supplied to the sterilized water discharge unit 20. The micropump 37 sends salt water stored in the salt water pack 36 to the electrolytic cell 35 in accordance with a control signal output from the control device 38. By doing so, high-concentration sterilized water is generated in the electrolytic cell 35.

  Then, the water discharge form of the water discharge apparatus WD of this embodiment is demonstrated, referring FIG. FIG. 5 shows a comparison between the water discharge state of tap water discharged from the tap water discharge unit 10 and the water discharge state of sterilized water discharged from the sterilized water discharge unit 20.

  When the water discharge part formed in the spout part 101 of the tap water discharge part 10 and the water discharge part formed in the spout part 201 of the sterilization water discharge part 20 are compared, the outer peripheral shape is the spout of the sterilization water discharge part 20. The water discharge part formed in the part 201 is small. The water discharge part formed in the spout part 201 of the disinfecting water discharge part 20 is formed to be smaller than the water discharge part formed in the spout part 101 of the tap water discharge part 10 in both the width direction and the depth direction. . The water film area formed when the sterilized water discharged from the sterilized water discharge unit 20 is landed is more than the water film area formed when the tap water discharged from the tap water spout unit 10 is landed. The outer peripheral area of the region where the plurality of sterilized water sprinkling holes are formed is configured to be smaller than the outer peripheral area of the region where the plurality of tap water sprinkling holes are formed. Furthermore, the space | interval of adjacent disinfection water sprinkling holes is comprised so that it may become smaller than the space | interval of adjacent tap water sprinkling holes.

  The water discharge state from the water discharge part formed in the spout part 101 of the tap water discharge part 10 gradually spreads immediately after water discharge. On the other hand, the water discharge state from the water discharge part formed in the spout part 201 of the disinfecting water discharge part 20 does not spread as much as possible immediately after water discharge. For this reason, the state of landing on the cutting board BD is such that tap water is widely landed and sanitized water is landed narrowly.

  When such a water discharge state and a water landing state are realized, a water landing state as shown in FIG. 6 is obtained by moving the cutting board BD after the water has landed. In this way, the landing state of the sterilized water is such that the water flows in a narrow range and interferes with each other in the narrow range. Therefore, compared with the landing state of tap water, water spreads in a narrow range as a whole. As a result, the amount of water that spills from the cutting board BD is less for sanitized water.

  After the water landing state as shown in FIG. 6, the user tilts the cutting board BD left and right as shown in FIG. 7, so that the sterilized water staying on the cutting board BD is evenly distributed on the cutting board BD. be able to.

  Then, the control flow at the time of the water discharge start in the disinfection water side of the water discharging apparatus WD is demonstrated, referring FIG. As a premise, it is assumed that the electromagnetic valve 32 is closed, the micropump 37 is turned off, and the electrolysis tank 35 is not energized and starts from a non-use state (step S101).

  The control device 38 determines whether or not the operation unit 203 is operated and discharge of sterilized water is requested (step S102). If the operation unit 203 is not operated, the determination in step S102 is repeated, and if the operation unit 203 is operated, the process proceeds to step S103.

  In step S103, the control device 38 outputs a control signal for opening the solenoid valve 32. In step S104 following step S103, it is determined whether or not a predetermined time has elapsed. If the predetermined time has not elapsed, the determination in step S104 is repeated, and if the predetermined time has elapsed, the process proceeds to step S105.

  In step S105, the control device 38 maintains the open state of the electromagnetic valve 32, drives the micropump 37, energizes the electrodes of the electrolytic cell 35, and generates highly concentrated sterilized water. The sterilized water is discharged from the sterilized water discharge unit 20 toward the sink SK.

  When the sterilizing water is discharged in such a step, tap water is first discharged to the cutting board BD, and then the sterilizing water is discharged. As shown in FIG. 9A, a part of the tap water that first reaches the cutting board BD remains on the cutting board BD while splashing water. Subsequently, as shown in FIG. 9B, the sterilized water reaches the cutting board BD. However, since the tap water film is already formed, the splash of the sterilized water is reduced. Further, as shown in FIG. 9C, even if the sterilized water remains on the cutting board BD, the subsequent splash of the sterilized water can be reduced.

  Next, another control flow at the time of starting water discharge on the sterilizing water side of the water discharge device WD will be described with reference to FIG. As a premise, it is assumed that the electromagnetic valve 32 is closed, the micropump 37 is turned off, and the electrolysis tank 35 is not energized and starts from a non-use state (step S201).

  The control device 38 determines whether or not the operation unit 203 is operated and discharge of sterilized water is requested (step S202). If the operation unit 203 is not operated, the determination in step S202 is repeated, and if the operation unit 203 is operated, the process proceeds to step S203.

  In step S203, the control device 38 outputs a control signal for opening the electromagnetic valve 32 and energizes the electrode of the electrolytic cell 35. In step S204 following step S203, it is determined whether or not a predetermined time has elapsed. If the predetermined time has not elapsed, the determination in step S204 is repeated, and if the predetermined time has elapsed, the process proceeds to step S205.

  In step S105, the control device 38 maintains the open state of the electromagnetic valve 32, drives the micro pump 37, maintains the energized state of the electrodes of the electrolytic cell 35, and generates high-concentration sterilized water. The sterilized water is discharged from the sterilized water discharge unit 20 toward the sink SK.

  Even if the sterilized water is discharged in such a step, the low concentration sterilized water reaches the cutting board BD until the micropump 37 is driven, so that a water film is formed by the low concentration sterilized water. It is possible to prevent the concentration of sterilized water from splashing.

  In the present embodiment, as shown in FIG. 11, the sterilized water discharge unit 20 is disposed at a position away from the center position in the left-right direction of the sink SK. Further, the sterilized water discharge unit 20 discharges sterilized water toward the center of the sink SK and obliquely in the front-rear direction.

  Further, as shown in FIG. 12, the bottom surface portion SK1 of the sink SK is provided with a drain port SK2, and a slope surface portion that is inclined downward toward the drain port SK2. The drain port SK2 is provided on one side of the sink SK in the left-right direction, and the sterilized water discharge unit 20 is provided on the other side of the sink SK in the left-right direction. The disinfecting water discharge unit 20 is formed so that the outer peripheral shape of the discharged water is a flat shape that is long in the front-rear direction of the sink SK.

  FIG. 13 shows an enlarged cross-sectional view of the sterilizing water spouting unit 20. As shown in FIG. 13, the spout portion 201 of the sterilized water spouting portion 20 is configured such that the sterilized water that flows along the water stop flows directly toward the mounting portion 202. Accordingly, the water discharge device WD is attached with the first water discharge state for discharging the sterilized water discharged from the sterilized water discharge unit 20 toward the sink SK and the sterilized water discharged from the sterilized water discharge unit 20. The second water discharge state is configured to be capable of forming the second water discharge state supplied to the unit 202, and the second water discharge state is such that the sterilized water discharged from the sterilized water discharge unit 20 flows along the outer surface of the spout unit 201. At the same time, the sterilizing water flowing along the outer surface of the spout unit 201 is guided to the mounting unit 202 (see FIG. 14). Further, the second water discharge state is configured to be automatically executed after executing the first water discharge state. In addition, the second water discharge state is formed by discharging sterilized water having a smaller flow rate than the first water discharge state.

  As shown in FIG. 15, the attachment unit 202 is provided with an operation unit 203 that switches between discharging and stopping the sterilized water from the sterilized water discharge unit 20.
