Also, in the drawings, some of the members that are not important for describing the embodiment are omitted.

  Drawing 1 is a side view showing the installation state of water discharging unit 10 provided with water discharging device 12 concerning an embodiment. FIG. 2 is a configuration diagram of the water discharge unit 10 including the water discharge device 12. In FIG. 2, a water channel is shown with a broken line. The water discharge unit 10 of this Embodiment functions as a water tap.

  The water discharge unit 10 includes a water discharge device 12, a temperature adjustment valve 16, a flow rate adjustment valve 18, an electric drive valve 20, and a control unit 22.

  The water discharge device 12 is installed in a sink 14 such as a kitchen. The temperature control valve 16, the flow rate control valve 18, and the electric drive valve 20 are installed in the discharge flow path 24. In particular, the temperature control valve 16, the flow control valve 18, and the electric drive valve 20 are arranged in this order from the upstream side. These are provided on the back side (lower side) 14 b of the sink 14.

  The water discharge device 12 includes a support member 40, a water discharge pipe 42, a first sensor member 28, a second sensor member 30, a water discharge head 26, a first operation member 32, and a second operation member 34. .

  The support member 40 is fixed to the sink 14. The water discharge pipe 42 is supported by the support member 40. The water discharge pipe 42 has a so-called gooseneck shape. The water discharge pipe 42 of the present embodiment is made of metal as a material. Each of the first sensor member 28 and the second sensor member 30 is an optical sensor, that is, a non-contact sensor, and detects the presence or absence of an object within a predetermined detection area. The first sensor member 28 has a detection area on the distal end side of the water discharge pipe 42. The second sensor member 30 has a detection area on the outer peripheral side of the water discharge pipe 42. The water discharge head 26 is provided on the distal end side (the side opposite to the support member 40) of the water discharge pipe 42. The water discharge head 26 discharges water sent from the water supply source through the discharge flow path 24 and the like. The first operation member 32 is an operation member for operating the temperature control valve 16. The second operation member 34 is an operation member for operating the flow rate adjustment valve 18.

  The temperature adjustment valve 16 is a hot / cold water mixing valve, and adjusts the mixing ratio of hot water supplied from the hot water supply passage 16a and cold water supplied from the supply water passage 16b in accordance with an operation on the first operating member 32. As a result, the temperature of the water flowing through the discharge flow path 24 and the temperature of the water discharged from the water discharge head 26 are adjusted.

  The flow rate adjustment valve 18 adjusts the opening degree of the valve portion in accordance with an operation on the second operation member 34. As a result, the flow rate of the water flowing through the discharge flow path 24 and the flow rate of the water discharged from the water discharge head 26 are adjusted.

  The electrically driven valve 20 is an electromagnetic valve, an electric valve, or the like, and opens and closes the discharge passage 24. When the electric drive valve 20 is opened, water whose temperature and flow rate are adjusted is supplied to the discharge flow path 58 and discharged from the water discharge head 26. When the electric drive valve 20 is closed, water is not supplied to the discharge flow path 24 and water discharge from the water discharge head 26 is stopped.

  The control unit 22 is a one-chip microcomputer or the like, and is configured by combining a CPU, a RAM, a ROM, and the like. The control part 22 of this Embodiment is integrated in the water discharging apparatus 12. FIG. The control unit 22 opens and closes the electric drive valve 20 according to the detection results of the first sensor member 28 and the second sensor member 30. That is, the water discharge device 12 of the present embodiment can switch the water discharge from the water discharge head 26 in a hands-free manner.

  3A and 3B are cross-sectional views of the water discharge head 26. FIG. The water discharge head 26 includes a first tube portion 44, a second tube portion 46, a first water discharge portion 48, a second water discharge portion 50, and a guide portion 60. FIG. 3A shows a state where the first water discharger 48 and the second water discharger 50 are in a first positional relationship for discharging the first pattern of water discharge, and FIG. 3B shows the first water discharger. 48 and the 2nd water discharging part 50 show the state which exists in the 2nd positional relationship which discharges the water discharge flow of the 2nd pattern different from a 1st pattern.

  In the present embodiment, the discharged water flow of the first pattern is a diffusion shower-like discharged water flow, and the discharged water flow of the second pattern is a straight shower-like discharged water flow or a straight discharged water flow. A straight water discharge flow means a water discharge flow discharged as a single water flow.

  The first cylinder portion 44 has a cylindrical shape. An inner side of the first tube portion 44 constitutes a water channel 52. The water channel 52 guides the water sent from the upstream side to the first water discharge unit 48.

  The first water discharger 48 has a plate shape, and is provided integrally with the first tube part 44 at the downstream end of the first tube part 44. In the first water discharge portion 48, a plurality of water discharge holes (shower water discharge holes) 48a penetrating the front and back are formed.

  Each of the plurality of water discharge holes 48a is configured to discharge a single linear water flow. In particular, the water discharge hole 48a extends in the outwardly extending direction so as to be located on the outer side toward the downstream side. Therefore, the water supplied to the first water discharger 48 is discharged in the form of a diffusion shower that spreads outward.

  The second cylindrical portion 46 has a cylindrical shape. The second tube portion 46 surrounds the first water discharge portion 48 and at least a part of the first tube portion 44.

  The second water discharge unit 50 has a plate shape like the first water discharge unit 48. The second water discharger 50 is provided integrally with the second cylinder part 46 via the guiding part 60 on the downstream side of the second cylinder part 46. In the second water discharge portion 50, a plurality of water discharge holes 50a penetrating the front and back are formed. In the present embodiment, the same number of water discharge holes 50 a as the water discharge holes 48 a of the first water discharge part 48 are formed in the second water discharge part 50. The water discharge holes 50a extend in parallel to each other. Hereinafter, the direction in which the water discharge hole 50a extends is referred to as the water discharge direction of the second water discharge portion.

  The plurality of water discharge holes 48a of the first water discharge section 48 and the plurality of water discharge holes 50a of the second water discharge section 50 are when the first water discharge section 48 and the second water discharge section 50 are in the first positional relationship, that is, the first water discharge. When the part 48 and the second water discharge part 50 overlap with each other with almost no gap, the downstream side of each water discharge hole 48a of the first water discharge part 48 and the upstream side of each water discharge hole 50a of the second water discharge part 50 face each other. It is formed as follows. More specifically, each water discharge hole 50 a of the second water discharge unit 50 is formed to have a larger diameter than an opening on the downstream side of each water discharge hole 48 a of the first water discharge unit 48. In addition, each water discharge hole 50 a of the second water discharge part 50 is formed so that an extension line of each water discharge hole 48 a of the first water discharge part 48 does not overlap the second water discharge part 50.

  When the first water discharge unit 48 and the second water discharge unit 50 are in the second positional relationship, the guiding unit 60 is configured such that a part of the water discharged from the first water discharge unit 48 is upstream of the second water discharge unit 50. That is, it is guided so as to flow along the surface 50c on the side of the first water discharge portion 48 toward the center portion of the surface 50c. In the present embodiment, the guiding unit 60 guides the water discharged from the first water discharging unit 48 in a direction orthogonal to the water discharging direction of the second water discharging unit 50.

  Specifically, the guide part 60 of the present embodiment is an annular part that surrounds the second water discharge part 50, and is provided integrally with the second water discharge part 50 on the outer peripheral side of the second water discharge part 50. In other words, the guiding portion 60 is an annular protruding portion that protrudes radially inward from the inner wall of the second cylindrical portion 46 at the downstream end of the second cylindrical portion 46. The guiding portion 60 has an annular flat surface 60a on the upstream side. The flat surface 60a is orthogonal to the water discharge direction, that is, the water discharge direction is the normal direction.

  The second water discharger 50 is configured to be movable between a position close to the first water discharger 48 and a position separated from the first water discharger 48 by a moving mechanism (not shown). In the present embodiment, the second water discharger 50 is configured to be movable in the water discharge direction. In addition, the 1st water discharging part 48 may be comprised so that a movement is possible. That is, the positional relationship between the first positional relationship and the second positional relationship may be switched by relatively moving the first water discharging unit 48 and the second water discharging unit 50.

  When the first water discharge part 48 and the second water discharge part 50 are in the first positional relationship, that is, when the first water discharge part 48 and the second water discharge part 50 overlap with each other with almost no gap, water is discharged from the first water discharge part 48. The diffusion shower-like water discharge flow passes through the water discharge hole 50a of the second water discharge portion 50 without hitting the second water discharge portion 50 and is discharged to the outside as a diffusion shower-like water discharge flow.

  When the first water discharger 48 and the second water discharger 50 are in the second positional relationship, that is, when the first water discharger 48 and the second water discharger 50 are separated by a predetermined distance, the first water discharger Water is guided so that at least a part of the diffusion shower-like water discharge discharged from 48 hits the flat surface 60a of the guiding portion 60, and flows toward the center of the surface 50c along the flat surface 60a and then the surface 50c, As a result, a water film is formed on the surface 50c. Another part of the diffusion shower-like water discharge flow hits the water film and rebounds, and the rebounded water is collected in the water chamber 54 between the first water discharge part 48 and the second water discharge part 50, and the accumulated water is the water discharge hole 50a. The water is discharged from. Since the water discharge hole 50a extends in the water discharge direction as described above, the water accumulated in the water chamber 54 is discharged from the water discharge hole 50a as a straight shower-like water discharge flow or a straight water discharge flow. That is, the diffusion shower-like water discharge flow is converted into a water discharge flow having a different pattern and discharged outside.

  According to the water discharging device 12 according to the present embodiment described above, when the first water discharging unit 48 and the second water discharging unit 50 are in the first positional relationship, the diffusion shower-like water discharged from the first water discharging unit 48. The water flow passes through the water discharge hole 50a of the second water discharge unit 50 as it is without hitting the second water discharge unit 50, and is discharged outside as a diffusion shower-like water discharge flow. That is, the first pattern of water discharge can be discharged accurately. Further, when the first water discharger 48 and the second water discharger 50 are in the second positional relationship, water accumulates in the water chamber 54, and the accumulated water is discharged from the water discharge hole 50 a of the second water discharger 50. Therefore, water is discharged from all the water discharge holes 50a of the second water discharge unit 50. That is, the water discharge flow of the second pattern can be discharged accurately. In particular, even when the water discharge amount (flow rate) is small, the water discharge flow of the second pattern can be discharged accurately. That is, according to the water discharging apparatus 12 which concerns on this Embodiment, a plurality of patterns of water discharge can be discharged accurately.

  The water discharging device according to the embodiment has been described above. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combination of each component, and such modifications are also within the scope of the present invention.

(Modification 1)
In the embodiment, a case has been described in which the same number of water discharge holes 50a as the water discharge holes 48a of the first water discharge part 48 are formed in the second water discharge part 50. However, the present invention is not limited to this.

  For example, the second water discharge portion 50 may be formed with a larger number of water discharge holes 50 a than the water discharge holes 48 a of the first water discharge portion 48. Also in this case, when the first water discharger 48 and the second water discharger 50 are in the second positional relationship, a part of the diffusion shower-like water discharge discharged from the first water discharger 48 hits the guide 60. A water film is formed, and another part of the diffusion shower-like water discharge flow hits the water film and bounces off. The bounced water is accumulated in the water chamber 54, and the accumulated water is discharged from all the water discharge holes 50a. Can be realized.

  According to this modification, the same operational effects as the operational effects achieved by the water discharge device 12 according to the embodiment can be achieved.

  For example, the second water discharge portion 50 may be formed with a smaller number of water discharge holes 50 a than the water discharge holes 48 a of the first water discharge portion 48. 4A and 4B are cross-sectional views of the water discharge head 26 according to a modification. FIGS. 4A and 4B correspond to FIGS. 3A and 3B, respectively. In the present modification, only one large water discharge hole 50 a is formed in the second water discharge unit 50. Also in this case, when the first water discharger 48 and the second water discharger 50 are in the second positional relationship, a part of the diffusion shower-like water discharge discharged from the first water discharger 48 hits the guide 60. A water film is formed, and another part of the diffusion shower-like water discharge flow hits the water film and rebounds. The bounced water accumulates in the water chamber 54, and the accumulated water is discharged from one water discharge hole 50a to a plurality of shower-like water. It is discharged as a single stream of water instead of a stream.

  4A and 4B, the water discharge hole 48a of the first water discharge part 48 is a water discharge hole 48a when the first water discharge part 48 and the second water discharge part 50 are in the second positional relationship. A part of the water discharged from the tube directly hits the inner wall of the second cylindrical portion 46. Specifically, in the water discharge hole 48a of the first water discharge part 48, when the first water discharge part 48 and the second water discharge part 50 are in the second positional relationship, the extension line of the water discharge hole 48a is the second tube part 46. It is configured to cross the inner wall. Thereby, the flow of the water which goes to the inner wall of the 2nd cylinder part 46, the flat surface 60a of the guidance | induction part 60, and the center part of the surface 50c of the 2nd water discharging part 50 is made, and it becomes easy to form a water film on the surface 50c. .

  According to this modification, the same operational effects as the operational effects achieved by the water discharge device 12 according to the embodiment can be achieved. In addition, according to this modification, since the shape of the second water discharger 50 becomes relatively simple, the manufacturing cost of the second water discharger 50 is reduced. Moreover, it becomes difficult for garbage to collect between the 1st water discharging part 48 and the 2nd water discharging part 50, and the frequency | count of a maintenance reduces or becomes unnecessary.

(Modification 2)
Various modifications can be considered for the shape of the guiding portion 60. 5A and 5B are cross-sectional views of the water discharge head, respectively. 5A and 5B, the display of the first water discharge portion 48 and the first tube portion 44 is omitted.

  In FIG. 5A, an annular recess 46 a that is recessed radially outward is formed on the inner peripheral side of the downstream end portion of the second cylindrical portion 46. The guide portion 60 faces the concave portion 46a in the axial direction. The outer peripheral surface of the second water discharger 50 has substantially the same diameter as the inner peripheral surface of the second cylindrical part 46. According to this modification, the same operation effect as the operation effect produced by the water discharging apparatus 12 concerning an embodiment can be produced. In addition, according to the water discharge device 12 according to the present embodiment, the outer peripheral surface of the second water discharge portion 50 has substantially the same diameter as the inner peripheral surface of the second tube portion 46, that is, the second water discharge portion 50 is effective. The area can be made relatively large.

  In FIG. 5B, the second cylindrical portion 46 is formed with a guiding portion 60 that is a bypass flow path that connects the upstream side and the downstream side of the water chamber 54. A part of the shower-like water flow discharged from the first water discharge portion 48 flows into the guide portion 60 from the upstream side of the guide portion 60 and flows out from the downstream side. In particular, the guiding portion 60 is configured such that water flowing out from the guiding portion 60 is directed along the surface 50c toward the center of the surface 50c. In addition, according to the water discharge device 12 according to the present embodiment, the flow of water toward the center of the surface 50c can be more reliably formed along the surface 50c by the guiding portion 60 that is a flow path, and on the surface 50c. A water film can be formed reliably.

(Modification 3)
Although not particularly mentioned in the embodiment, when the first water discharge portion 48 and the second water discharge portion 50 are in the second positional relationship, not a straight shower-like water discharge flow but a straight water discharge flow is realized. The configuration will be described.

  FIG. 6 is a diagram of the second water discharge unit 50 and the guide unit 60 viewed from the water discharge direction. In FIG. 6, each of the plurality of water discharge holes 50 a is formed such that the distance L to at least one other water discharge hole 50 a is 0.45 mm or less. That is, each of the plurality of water discharge holes 50a is formed such that the distance from the closest water discharge hole 50a is 0.45 mm or less. In this case, the water discharged from each water discharge hole 50a attracts and merges with the water discharged from at least the adjacent water discharge holes 50a to form one flow. Thereby, all the water discharged from the plurality of water discharge holes 50a is easily collected to form a single flow, that is, a straight water discharge flow.

(Modification 4)
7A and 7B are cross-sectional views of a water discharge head according to another modification. FIGS. 7A and 7B correspond to FIGS. 3A and 3B, respectively. In the present modification, each of the plurality of water discharge holes 50a of the second water discharge unit 50 is formed such that the downstream opening 50d is larger than the upstream opening 50e. Particularly in the illustrated example, each of the plurality of water discharge holes 50a of the second water discharge unit 50 is formed so as to expand toward the downstream side, and more specifically, the cross-sectional area increases toward the downstream side. The upstream opening 50e may be the same size as the downstream opening 48b of the water discharge hole 48a of the first water discharge section 48.

According to this modification, since the upstream opening 50e is smaller than the downstream opening 50d, the first water discharge portion 48 and the second water discharge portion 50 are in the second positional relationship as compared with the case where they are the same. In some cases, water tends to accumulate in the water chamber 54, and water is likely to be discharged from all the water discharge holes 50 a of the second water discharge portion 50. In particular, even when the water discharge amount (flow rate) is small, water is likely to be discharged from all the water discharge holes 50a of the second water discharge unit 50. In addition, according to this modification, the downstream opening 50d is larger than the upstream opening 50e. In other words, the downstream opening 50d is relatively wide. In other words, the downstream opening 50d of the water discharge hole 50a. Since the distance between them is relatively short, when the first water discharge portion 48 and the second water discharge portion 50 are in the second positional relationship, the water discharged from the water discharge holes 50a is discharged from the adjacent water discharge holes 50a. Easy to unite with water. That is, it is easy to form a straight water discharge flow.
Thus, according to the present modification, it is possible to realize a water discharge device that can accurately form a straight water discharge flow as the water discharge flow of the second pattern.

  Any combination of the above-described embodiments and modifications is also useful as an embodiment of the present invention. The new embodiment generated by the combination has the effects of the combined embodiment and the modified examples. In addition, it should be understood by those skilled in the art that the functions to be fulfilled by the constituent elements described in the claims are realized by the individual constituent elements shown in the embodiments and the modified examples or by their linkage. .
