Description

  The present invention relates to a faucet device provided with a discharge part for discharging water and a discharge part for discharging a cleaning liquid.

  A faucet device provided with a water discharge part for discharging water and a cleaning liquid discharge part for discharging a cleaning liquid is known from Patent Document 1. The water faucet device has a structure in which both discharge portions are arranged side by side so as to be separated from each other, and the cleaning liquid does not easily adhere to the water discharge portion.

Japanese Patent No. 2957396

  By the way, in the faucet device provided with the water discharge part and the washing discharge part as shown in Patent Document 1, drinking water may be discharged from the water discharge part. In this case, for example, it is necessary to reliably prevent the cleaning liquid adhering to the cleaning liquid discharge part after use from being transmitted to the outer surface of the faucet device by surface tension and flowing to the water discharge part side to be contaminated. . As measures against this, for example, it is conceivable to dispose the two discharge parts at a large distance, or to lengthen the protruding length of both discharge parts. However, this causes an increase in the size of the water faucet device and a decrease in design. There is a fear.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a faucet device that can reliably prevent a cleaning liquid from being mixed with drinking water, and that can achieve downsizing and improvement in design. .

  In order to solve the above-mentioned problem, the first faucet device of the present invention has a drinking water discharge part 6a for discharging drinking water and a cleaning liquid discharge part 6b for discharging cleaning liquid juxtaposed to provide a drinking water discharge part 6a or A water-repellent film treatment is performed between at least one of the cleaning liquid discharge portions 6b or between them.

  In this way, by performing the water-repellent coating treatment between the drinking water discharge part 6a or the cleaning liquid discharge part 6b or between them, the water drainage of these parts can be improved after use. The adhering drinking water travels along the outer surface of the nozzle 15 due to surface tension to the drinking water discharge part 6a, or the drinking water adhering to the cleaning liquid discharge part 6b and the drinking water adhering to the drinking water discharge part 6a are surrounded by the surface tension. As a result, it is possible to prevent the drinking water discharge part 6a from being soiled with the cleaning liquid. Therefore, it is possible to reliably prevent the drinking water discharge unit 6a from being contaminated with the cleaning liquid, and safer drinking water can be discharged from the drinking water discharge unit 6a. In addition, by performing the water-repellent coating treatment in this manner, the drinking water discharge part 6a is prevented from being soiled with the cleaning liquid, so that the drinking water discharge part 6a and the cleaning liquid discharge part 6b are disposed at relatively close positions. The protruding length of the drinking water discharge part 6a and the cleaning liquid discharge part 6b can be shortened to reduce the size of the faucet device 1 and improve the design.

  In the second faucet device of the present invention, a drinking water discharge part 6a for discharging drinking water and a cleaning liquid discharge part 6b for discharging cleaning liquid are juxtaposed and protruded downward, and the discharge of the drinking water discharge part 6a At least one of the front end surface on which the outlet 23 is formed and the front end surface on which the discharge port 24 of the cleaning liquid discharge unit 6b is formed is inclined downward toward the opposite side to the other discharge unit. .

  In this way, by tilting the distal end surface of the drinking water discharge part 6a or the distal end surface of the cleaning liquid discharge part 6b downward toward the opposite side of the other discharge part, the drinking water attached to the drinking water discharge part 6a after use or The cleaning liquid adhering to the cleaning liquid discharge part 6 is likely to flow down in the direction away from the other discharge part along the inclination, and thus the drinking water discharge part 6a can be prevented from being soiled with the cleaning liquid. Moreover, since the drinking water discharge part 6a is prevented from being contaminated with the cleaning liquid by inclining the front end surface of the drinking water discharge part 6a or the front end surface of the cleaning liquid discharge part 6b in this way, the drinking water discharge part 6a and the cleaning liquid discharge The part 6b can be disposed at a relatively close position, and the faucet device 1 can be miniaturized and the design can be improved.

  In the first and second faucet devices, the switching means for switching and supplying drinking water to either one of the drinking water discharge part 6a and the cleaning liquid discharge part 6b, and the supply to the cleaning liquid discharge part 6b side It is preferable to provide a detergent supply unit that supplies detergent to the drinking water.

  In this case, detergent can be mixed with drinking water in the detergent supply unit to obtain a cleaning liquid discharged from the cleaning liquid discharge unit 6b, and the supplied drinking water can be used only as drinking water discharged from the drinking water discharge unit 6a. Instead, it can also be used as a cleaning liquid discharged from the purified liquid discharge portion 6b.

  In this invention, it can prevent reliably that a washing | cleaning liquid is mixed with drinking water, and also it can implement | achieve size reduction and an improvement in design property.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. A faucet device 1 according to an example of the present embodiment is provided in a sink 2 as shown in FIG. 2 and can discharge selected one of drinking water and cleaning liquid to a sink 3.

  The faucet device 1 includes a water supply channel 5 through which drinking water is supplied from the water supply, and a drinking water discharge unit 6 a that discharges drinking water and a cleaning liquid discharge unit 6 b that discharges cleaning liquid are provided at the downstream end of the water supply channel 5. Is provided (see FIG. 4).

  In the upstream portion of the water supply channel 5 that is passed through the sink 2, a stop cock 7, a check valve 8, a constant flow valve 9, and an on-off valve 10 including an electromagnetic valve are provided in that order from the upstream side.

  The downstream part of the water supply channel 5 is composed of a currant 11 erected on the peripheral edge of the sink 3. As illustrated in FIG. 1, the currant 11 includes a vertical tube portion 12, a horizontal tube portion 13, and a nozzle 15 that are provided in order from the upstream side.

  The horizontal tube portion 13 protrudes forward from the upper end portion of the vertical tube portion 12, and the nozzle 15 is provided so as to protrude downward from the front end portion of the horizontal tube portion 13. The nozzle 15 may be provided so as to swing freely within a predetermined movable range with respect to the horizontal tube portion 13 or may be provided fixedly.

  A motor-operated valve 16 for adjusting the amount of water flowing through the water supply channel 5 is provided below the vertical pipe portion 12. The operation of the motor-operated valve 16 and the on-off valve 10 is controlled by a control unit 17 built in the sink 2. An operation unit 18 is provided below the vertical tube unit 12, and operation information of the operation unit 18 is transmitted to the control unit 17 as an electrical signal. By operating the operation unit 18, the opening of the motor-operated valve 16 is adjusted to adjust the amount of water supplied to the downstream side, or the opening and closing of the on-off valve 10 is switched to determine whether water is discharged from the discharge units 6 a and 6 b. It can be switched.

  As shown in FIG. 1, an air release valve 19 made of a float valve is provided at the upper end portion of the substantially vertical vertical pipe portion 12. The air release valve 19 rises and closes the air release hole 20 formed in the vertical pipe portion 12 when the on-off valve 10 is opened and water is flowing through the water supply channel 5. When the on-off valve 10 is closed, the atmosphere release valve 19 descends to open the atmosphere release hole 20, whereby the water remaining on the downstream side of the atmosphere release hole 20 in the water supply channel 5 becomes the drinking water discharge unit 6 a or The liquid is discharged from the cleaning liquid discharger 6b.

  The nozzle 15 has a substantially cylindrical outer shape and includes a detachable detergent tank 21. The detergent tank 21 is provided with an openable / closable lid 22 so that the detergent tank 21 can be replenished with the detergent by opening the lid 22.

  As shown in FIG. 4, the drinking water discharge part 6 a and the cleaning liquid discharge part 6 b are provided side by side in the left-right direction at the lower end part of the nozzle 15. Both the discharge parts 6a and 6b are cylindrical and project downward from the nozzle 15, and are spaced apart so as to form a gap between the both discharge parts 6a and 6b. Further, the protruding lengths of both the discharge portions 6a and 6b are substantially the same.

  Among these, the drinking water discharge part 6a discharges drinking water straightly, and the lower end part (front-end | tip part) is formed with one circular hole opened downward as the drinking water discharge port 23. FIG. The cleaning liquid discharge part 6b discharges the cleaning liquid in a shower-like manner, and a plurality of holes 24a that open below the potable water discharge port 23 as a cleaning liquid discharge port 24 are formed at the lower end (front end) thereof. Is formed.

  As shown in FIGS. 1 and 3, a discharge passage 25 that forms an end portion on the downstream side of the water supply passage 5 is formed inside the nozzle 15. The discharge path 25 includes a drinking water path 25a that connects the horizontal pipe section 13 and the drinking water discharge section 6a, and a cleaning water path 25b that branches from the drinking water path 25a and connects the drinking water path 25a and the cleaning liquid discharge section 6b. It consists of and.

  A switching valve 28 shown in FIG. 5 is provided as a switching means in the discharge channel 25 downstream of the branch point 26 that branches into the drinking water channel 25a and the cleaning water channel 25b. The switching valve 28 switches whether to supply the drinking water supplied from the upstream side to the drinking water channel 25a side or the cleaning water channel 25b side. The switching valve 28 is constituted by a slide valve, and is manually slid in the direction of the arrow shown in FIG. 5 so that the drinking water channel 25a can be closed and drinking water can be supplied to the cleaning water channel 25b as shown in FIG. The state can be switched between the state shown in FIG. 5 (b) in which the washing water channel 25b side is closed and drinking water can be supplied to the drinking water channel 25a.

  The drinking water supplied to the drinking water channel 25a is discharged as it is from the drinking water discharge port 23 toward the sink 3 below. On the other hand, the drinking water supplied to the cleaning water channel 25b is mixed with bubbles and detergent or only bubbles as described below, and is discharged from the cleaning liquid discharge port 24 as a cleaning liquid.

  As shown in FIG. 3, a narrowed portion 29 having a smaller flow passage area is formed on the downstream side of the branch point 26 of the cleaning water channel 25 b, and the negative pressure generating portion 30 is downstream of the narrowed portion 29. Yes. The negative pressure generating unit 30 is formed with an outside air intake port 31 that allows the cleaning water channel 25b to communicate with the outside. When potable water flows into the cleaning water channel 25b, negative pressure is generated in the negative pressure generating unit 30, whereby external air is supplied from the outside air intake 31 to the cleaning water channel 25b as indicated by an arrow on the right side of the drawing in FIG. The That is, the negative pressure generating unit 30 constitutes a gas mixing unit that mixes gas.

  On the downstream side of the negative pressure generating unit 30 in the cleaning water channel 25b, a pressure reducing / pressurizing unit 32 that is increased after the flow channel area is reduced in the flow direction of the cleaning water is formed. Since the water flowing through the pressure reducing / pressurizing unit 32 fluctuates in pressure, the air bubbles mixed in the negative pressure generating unit 30 are sheared and refined.

  The detergent tank 21 is connected to the decompression / pressurization unit 32 via a detergent supply path 33. The detergent supply path 33 is provided with a valve 35 that is manually operated by a valve operating portion 36 (see FIG. 2) provided in the nozzle 15. When the valve operating unit 36 is operated and the valve 35 is opened while water is flowing in the cleaning water channel 25b, a detergent is generated as indicated by an arrow on the left side of the drawing in FIG. The detergent in the tank 21 is supplied to the washing water passage 25b through the detergent supply passage 33, and the detergent is mixed with the drinking water containing the bubbles. That is, in this example, a detergent supply unit that supplies detergent to drinking water is configured by the decompression / pressurization unit 32 that serves as a means for reducing bubbles.

  The faucet device 1 switches between a state in which drinking water is discharged from the drinking water discharge port 23 and a state in which the cleaning liquid is discharged from the cleaning liquid discharge port 24 by switching the switching valve 28 with the on-off valve 10 opened. Can do.

  In addition, the cleaning liquid discharged from the cleaning liquid discharge port 24 is changed to either a detergent and a cleaning liquid containing fined bubbles or a cleaning liquid containing only fined bubbles by switching opening and closing of the valve 35. Can do. Of these, cleaning liquids containing detergent and bubbles are particularly effective for cleaning objects to be cleaned such as dishes, because the cleaning effect of the detergent and the effect of bubbles are enhanced. Further, when a cleaning liquid containing only bubbles is discharged, the object to be cleaned can be cleaned with water containing bubbles having a high cleaning effect without consuming detergent, which is economical.

  Here, in the faucet device 1 of the present example, the water repellent coating treatment is applied to each of the discharge portions 6a and 6b. This water-repellent coating treatment may be applied to all of the lower surface, outer peripheral surface, and inner surface of each of the discharge portions 6a and 6b, and one or a plurality of selected ones may be subjected to the water-repellent coating treatment. Also good. In addition to these, a water-repellent film treatment may also be applied to the lower surface of the nozzle 15 on which the ejection portions 6a and 6b are projected. Alternatively, the water-repellent coating treatment may be performed only on the portion between the discharge portion 6a and the discharge portion 6b in the lower surface of the nozzle 15 on which the discharge portions 6a and 6b are projected.

  By performing the water-repellent coating treatment in this way, it is possible to improve the water drainage of each of the discharge portions 6a and 6b when the on-off valve 10 is closed and the discharge of drinking water or cleaning liquid is stopped. For this reason, for example, drinking water that has adhered to the cleaning liquid discharge part 6b after use reaches the drinking water discharge part 6a through the outer surface of the nozzle 15 due to surface tension, or the drinking water and drinking water discharge part that has adhered to the cleaning liquid discharge part 6b. It is possible to reliably prevent the potable water adhering to 6a from being connected to the surrounding outer surface by surface tension and consequently contaminating the potable water discharge section 6a with the cleaning liquid. Safe drinking water can be discharged from 6a. In addition, by performing the water-repellent coating treatment in this manner, the drinking water discharge part 6a is prevented from being soiled with the cleaning liquid, so that the drinking water discharge part 6a and the cleaning liquid discharge part 6b are disposed at relatively close positions. The projection length of the drinking water discharge part 6a and the cleaning liquid discharge part 6b can be shortened, and the faucet device 1 can be reduced in size and improved in design.

  In this example, the water-repellent coating treatment is applied to the drinking water discharge portion 6a and the cleaning liquid discharge portion 6b. However, the water-repellent coating treatment may be applied only to either the drinking water discharge portion 6a or the cleaning liquid discharge portion 6b. Shall.

  Moreover, although the faucet device 1 of this example mixes a detergent with the drinking water containing air bubbles, after supplying a detergent to drinking water, the gas used as a bubble may be mixed.

  Next, a faucet device 1 of another example different from the above example will be described. In the following description, the same components as those in the example are given the same numbers, and redundant descriptions are omitted.

  In the faucet device 1 of the example, the lower end surfaces of the drinking water discharge part 6a and the cleaning liquid discharge part 6b are substantially horizontal as shown in FIG. As shown in FIG. 6, the lower end surface (tip surface) where the drinking water discharge port 23 of the drinking water discharge portion 6 a is formed is an inclined surface 37 that gradually descends toward the opposite side of the cleaning liquid discharge portion 6 b, The protruding length of the drinking water discharge part 6a is made shorter as it goes away from the cleaning liquid discharge part 6b.

  By inclining the lower end surface of the drinking water discharge portion 6a in this way, the drinking water attached to the drinking water discharge portion 6a after use flows down along the inclined surface 37 in a direction away from the other cleaning liquid discharge portion 6. As a result, it is possible to reliably prevent the drinking water discharge part 6a from being contaminated with the cleaning liquid.

  In FIG. 6, the lower end surface (tip surface) of the cleaning liquid discharge portion 6b is horizontal, but the same surface is formed as an inclined surface 38 that gradually inclines downward toward the opposite side of the drinking water discharge portion 6a as shown in FIG. Also good. Further, contrary to FIG. 6, the lower end surface of the cleaning liquid discharge portion 6b may be horizontal and the lower end surface of the cleaning liquid discharge portion 6b may be an inclined surface 38 similar to FIG. Further, in this example, the drinking water discharge part 6a and the cleaning liquid discharge part 6b may or may not be subjected to a water-repellent film treatment as in the example.

  Moreover, each said example may be applied to the faucet device 1 shown in FIG. 8, and this faucet device 1 is demonstrated below. In the following description, the same number is assigned to the same configuration as the faucet device 1 of each example described above, and a duplicate description is omitted.

  In the water faucet device 1 shown in FIG. 8, a hot water / mixing unit 39 is provided in the water supply channel 5, and the water supply channel 5 upstream of the hot water / mixing unit 39 includes a water pipe 40 and a hot water pipe 41. ing. Normal temperature drinking water is supplied from the water supply to the water pipe 40, and high temperature drinking water heated through the water heater is supplied to the hot water pipe 41. The adjusted drinking water is supplied to the downstream side of the water supply channel 5.

  A manual operation unit 42 including a lever is provided at a lower portion of the vertical pipe unit 12 of the currant 11. By operating the manual operation unit 42, a mixing ratio of hot water and water mixed in the hot water mixing unit 39 and The supply amount of the mixed water to the downstream side can be manually adjusted.

  The check valve 8 and the constant flow valve 9 are provided on the downstream side of the hot water / mixer 39. In addition, since the hot and cold mixing unit 39 has a function of changing the presence and amount of potable water supplied to the downstream side of the water supply channel 5, in the faucet device 1 of this example, the on-off valve 10 and the motor operated valve 16 Is not provided.
