  However, in the liquid outflow device having such a configuration, the switching unit, the supply path, the dispersion plate, the space including the shower outflow member, and the shower outflow member are sequentially stacked and arranged. Thickness is required in the outflow direction. Therefore, a compact liquid outflow device for a water purifier in the outflow direction of the shower has been desired.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a liquid outflow device that is compact in the outflow direction of a shower without impairing a uniform outflow state.

The characteristic configuration of the liquid outflow device for a water purifier to achieve the above object is as follows:
A shower section with a purified water outflow section that discharges purified water that has purified raw water, a raw water outflow section that flows out in a DC state without purifying the raw water, and a shower outflow member that flows out in a shower form without purifying the raw water. And a switching unit that receives supply of raw water and supplies the raw water to any of the purified water outflow unit, the raw water outflow unit, and the shower unit.
The shower outflow member includes a plurality of discharge holes,
The shower section,
An annular space with an axis along the direction of flow of the shower outflow member, and the first space of annular shape having one end surface in the axial direction of the annular space is connected with said shower outlet member, said shaft A second space connected to the other end surface of the first space in the center direction,
From the switching unit, in a state facing the tangential direction of the first space, comprises a supply path of raw water communicating with the second space,
The switching unit and the supply path are provided side by side in a direction orthogonal to the axis .

According to the above-mentioned characteristic configuration, by providing the supply path in a state where the supply path is oriented in the tangential direction of the first space from the switching section, the switching section, the shower section, and the supply path are arranged on substantially the same plane, and the liquid outflow device is provided. Can be configured.
In such a configuration, if the supply path is provided so as to directly communicate with the first space, the pressure and flow velocity of the fluid vary in the vicinity of the supply path in the first space and in other parts, and the shower There is a possibility that the outflow state from the shower outflow member of the part becomes uneven.
However, by connecting the supply path to the second space, and further providing the supply path in a tangential direction to the first space, the fluid flowing from the supply path, from the position of the second space away from the shower outflow member, Since the gas can be supplied to the first space while maintaining the tangential flow velocity, the uniformity of the outflow from the shower section is not impaired.
Therefore, the switching section, the shower section, and the supply path are arranged on substantially the same plane, the thickness of the shower outflow member in the axial direction along the outflow direction is reduced, and a uniform outflow state is not impaired, and a compact A liquid outflow device can be provided.
Note that the outflow direction of the shower outflow member refers to a direction in which the outflow directions of raw water flowing out in a shower shape are averaged.

Further, according to the embodiment, as described above, the fluid is supplied from the second space to the first space while maintaining the tangential flow velocity. Therefore, the flowing water is supplied from the first space to the discharge holes while maintaining the swirling flow.
Therefore, the flowing water is supplied to the discharge holes while maintaining the flow vector crossing the direction of the discharge holes.
In this case, the raw water flowing out of the discharge hole can flow out as a shower flow from the discharge hole while maintaining the kinetic energy of the swirling flow.
That is, the discharge direction of the fluid flowing out of each discharge hole is shifted from the direction of the discharge hole to a certain extent in the same direction and flows out, and as a result, a wide, wide-angle, soft hand-held shower is obtained. A flow can be formed.
Therefore, it is possible to provide a compact liquid outflow device that can form a shower flow that swirls and diffuses without reducing the uniform outflow state while reducing the thickness in the axial direction along the outflow direction of the shower.

Can be supplied to the first space. Therefore, the liquid can be uniformly discharged from the shower section.

Further features of the liquid outflow device for a water purifier of the present invention include:
The supply path is at a point communicating with a position of the second space separated from the first space in the axial direction.

  According to the above-described characteristic configuration, the communication section in which the supply path and the second space communicate with each other and have a high flow velocity can be kept away from the first space. As a result, the communication part between the supply path and the second space can be kept away from the shower outflow member. Therefore, after the liquid supplied from the supply path forms a stable swirling flow in the second space, it can be supplied from the second space to the first space while maintaining the swirling flow. Therefore, the liquid can be stably discharged from the shower outflow member.

Further features of the liquid outflow device for a water purifier of the present invention include:
The discharge holes have circular openings, and are arranged in the same direction on a disk surface concentric with the first space.

According to the embodiment, by arranging the discharge holes on the disk, the thickness of the first space in the axial direction can be reduced, and a compact liquid outflow device can be provided. In addition, the flowing water is supplied to the circular discharge hole while maintaining a flow vector crossing the direction of the circular discharge hole. Then, the flowing water supplied to the circular discharge hole first collides with the wall surface of the circular discharge hole.
In this case, the raw water flowing out of the circular discharge hole can flow out as a shower flow from the circular discharge hole in a direction substantially opposite to the flow direction of the swirl flow while maintaining the kinetic energy of the swirl flow.
That is, the discharge direction of the fluid flowing out of each discharge hole is uniformly shifted in the same direction from the direction of the circular discharge hole to the same direction, so that the fluid flows out. It is possible to form a shower flow with a sense of hand.
Therefore, it is possible to provide a compact liquid outflow device capable of forming a shower flow that swirls and diffuses favorably while reducing the thickness in the axial direction along the outflow direction of the shower.

Further features of the liquid outflow device for a water purifier of the present invention include:

Hereinafter, the horizontal direction in the side view of the water purifier is referred to as “width direction W”, the vertical direction is referred to as “height direction H”, and the depth direction in the drawing is referred to as “depth direction D”. In the present embodiment, the water purifier is arranged so that the width direction W and the depth direction D coincide with the horizontal direction, and the height direction H coincides with the vertical direction.

As shown in FIGS. 1, 2, and 6 to 11, the liquid outflow device 100 is an annular space having an axis P along the outflow direction of the shower outflow member 2 </ b> A in the shower section 2, and the axial center of the annular space. One of the axial directions of P is connected to the shower outflow member 2A in the first space R1, the second space R2 connected to the other of the first spaces R1, and the switching unit CS in the tangential direction of the first space R1. And a supply path 4 communicating with the second space R2 in the closed state.
In this example, the axial direction of the axis P and the outflow direction of the shower outflow member 2A are the same.

The shower unit 2 is a member that causes the supplied raw water to flow out in a shower shape.
The shower section 2 includes a shower outflow member 2A, a first space R1, a second space R2, and a casing 2C.
Here, the casing 2 </ b> C is a member that forms an outer peripheral portion of the shower unit 2. In this example, the casing 2C includes a first space R1 and a second space R2 therein, holds the shower outflow member 2A, and is formed in a form in which a purifying unit 70 described later is placed.

The first space R1 is a space for supplying raw water to the shower outflow member 2A.
This first space R1 is provided with a shower outflow member 2A on an end face which is one end. The shower outflow member 2A is provided so as to flow out of the shower approximately downward, for example. In this embodiment, the case where the outflow direction of the shower outflow member 2A matches the direction of the height direction H is shown.
The first space R1 is provided as an annular space having an axis P substantially parallel to the outflow direction of the shower outflow member 2A.
This concept of an annular space includes an annular or cylindrical space.

The first space R1 is provided in the internal space of the casing 2C as a substantially cylindrical space along the axis P, as shown in FIGS. In the present embodiment, the purified water outflow portion 1 having the axis P as the central axis is arranged in the cylinder of the first space R1. That is, the purified water outflow unit 1 is located at the axial center of the first space R1.
The outer peripheral portion of the first space R1 is formed in a circular shape partitioned by the casing 2C.
The inner peripheral portion of the first space R1 is formed in a circular shape on the outer peripheral region of the purified water outflow portion 1. And in this example, the inner peripheral part of the 1st space R1 and the outer peripheral part of the purified water outflow part 1 are shared as 1 C of wall surfaces.
That is, the inside of the first space R1 is configured to be able to form a swirling flow F in which the liquid rotates around the axis P. That is, the first space R1 is provided as an annular space.

The first space R1 will be supplemented.
In the present embodiment, the first space R1 is a space existing in a space defined by the inner wall of the casing 2C, the shower outflow member 2A, and the purified water outflow portion 1.
As shown in FIG. 9, the first space R1 is an inner wall of the casing 2C, a shower outflow member 2A, and a wall surface of the purified water outflow portion 1 which is a wall surface closest to the shower outflow member 2A and opposed to the shower outflow member 2A. This is a space defined by the virtual plane L1 including 1B.

The second space R2 is a space that once receives the raw water supplied from the supply path 4 and further supplies the raw water to the first space R1, as shown in FIGS.
In the present embodiment, the second space R2 is provided adjacent to the shower outflow member 2A and another end surface which is another end portion of the first space R1, and all adjacent portions thereof are communicated with each other.
The second space R2 does not have to have a space shape in which the raw water supplied from the supply passage 4 stays or generates a vortex in the second space R2, and the space shape includes an annular space.
In the present example, the second space R2 is provided as an annular space having the axis P as its axis. In the present embodiment, the second space R2 is provided as a substantially cylindrical space having the purified water outflow portion 1 at the axis P. The inner diameter of the second space R2 is provided with an inner peripheral portion configured to be larger than the inner diameter of the first space R1. In this example, the inner peripheral portion is formed by the wall surface 1C. As the inner diameter of the second space R2, that is, the diameter of the inner peripheral portion, the diameter of the smallest inner peripheral portion of the second space R2 is determined as the inner diameter of the second space R2.
Further, the inside of the second space R2 is configured such that a swirling flow F in which the liquid rotates around the axis P can be formed. In the present example, an obstacle such as a protrusion or a baffle that obstructs the swirling flow F is not actively provided inside the second space R2.

The supply path 4 is a supply path for supplying raw water to the second space R2. The supply path 4 is included in a shower flow path W2 that communicates with the switching section CS and guides raw water from the switching section CS to the discharge hole 2B.
The supply path 4 is connected to the second space R2 from the switching unit CS in a state of being directed in a tangential direction of the first space R1 and further in a state of being directed in a tangential direction of the second space R2.
Therefore, the raw water supplied from the supply path 4 is supplied to the second space R2 while maintaining the energy of the flow, and forms a swirling flow F in the space of the second space R2.
The direction of the swirling flow F is the same as the direction of the flow of the raw water supplied from the supply path 4. Therefore, a swirling flow F in the same direction as the flow direction of the supply path 4 is formed.

The second space R2 will be supplemented.
In the present embodiment, the second space R2 is a space other than the first space R1 in the space defined by the inner wall of the casing 2C, the shower outflow member 2A, and the purified water outflow section 1.
Therefore, in the present embodiment, the outer diameter of the second space R2 is substantially the same as the outer diameter of the first space R1.

The relationship between the switching unit CS, the shower unit 2, and the supply path 4 will be supplemented.
As described above, the supply path 4 is connected to the second space R2 from the switching unit CS in a state tangential to the first space R1 and further in a state tangential to the second space R2. Therefore, the switching section CS, the shower section 2 and the supply path 4 are respectively arranged on substantially the same plane (not shown) as shown in FIG.

A supplementary description will be given of the positional relationship among the supply path 4, the first space R1, and the second space R2.
The lower end of the supply path 4 in the outflow direction of the shower is provided so as to be the same as the boundary between the first space R1 and the second space R2 (corresponding to the wall surface 1B in this embodiment) or to be located more upstream. I have. Therefore, the supply path 4 communicates with the other side of the axial side of the second space R2. That is, the first space R1 is provided on the other end side.

The supplementary description of the shower outflow member 2A, the first space R1, and the second space R2 will be provided.
As described above, since the raw water forms the swirl flow F in the second space R2, the raw water flowing in the second space R2 is supplied to the first space R1 while maintaining the swirl flow. Become. Therefore, the raw water forms the swirling flow F in the space of the first space R1.
Therefore, the raw water in the first space R1 is supplied to the shower outflow member 2A while maintaining the swirling flow. As described above, the swirling flow F is a swirling flow in the same direction as the flow direction of the supply path 4.

The shower outflow member 2A is a nozzle member that allows raw water to flow out in a shower shape.
In this embodiment, the shower outflow member 2A is formed in a disk shape having the same center as the axis P.

The shower outflow member 2A is configured as a nozzle member having a plurality of discharge holes 2B as shown in FIGS. 2, 3, 7, 9, and 11.
In the present embodiment, the discharge holes 2B have a planar outer diameter smaller than the inner diameter of the second space R2 of the shower outflow member 2A and are arranged on a disk surface centered on the axis P. That is, the ejection holes 2B are arranged inside a range surrounded by a virtual line L2 passing through the wall surface 1C in FIG.
Therefore, the raw water supplied from the second space R2 is supplied while turning from the outer peripheral portion to the inner peripheral side of the first space R1, and flows out from the discharge hole 2B.
In addition, the arrangement method of the ejection holes 2B does not matter. For example, they can be arranged in a ring or spiral. In addition, they can be arranged in a square lattice or a staggered lattice.

  The discharge hole 2B is a small opening having an opening cross section that is sufficiently smaller than the purified water outflow portion 1 and the raw water outflow portion 3. In the present embodiment, the discharge hole 2B is provided as an opening having a smaller diameter than the purified water outflow portion 1 and the raw water outflow portion 3.

The discharge hole 2B is a circular opening in the present embodiment.
The discharge hole 2B is further provided as a substantially cylindrical opening portion whose opening direction is provided in parallel with the axis P. The substantially cylindrical opening is formed in a substantially cylindrical shape including a conical element whose diameter gradually decreases from the upstream side toward the outflow side.
By making the outlet side (outlet side) slightly smaller than the upstream side in this way, an appropriate pressure loss is applied to the discharge hole 2B when the raw water flows out, and even when the raw water outflow amount is large, the raw water Even when the outflow amount of the raw water is small, the phenomenon that the raw water is dripped on the surface of the shower outflow member 2A is suppressed, and the raw water can flow out in a shower state in a wide flow rate range.

The relationship between the discharge hole 2B and the first space R1 will be supplemented.
As described above, as shown in FIG. 11, raw water is supplied from the first space R1 to the shower outflow member 2A having the discharge hole 2B while maintaining the swirling flow. Therefore, the raw water is supplied to the discharge hole 2B while maintaining a large flow vector that intersects orthogonally with the axial direction of the discharge hole 2B.
Therefore, the raw water flowing out from the discharge hole 2B flows out as a shower flow from the discharge hole 2B while maintaining the kinetic energy of the flow in the direction of the swirl flow F. That is, as shown in FIG. 11, the flow vector of the swirl flow F in the swirl direction is reflected by the inner wall of the discharge hole 2B and converted, and a vector substantially opposite to the flow vector in the direction of the swirl flow F is maintained. In this state, it flows out of the discharge hole 2B as a shower flow at an angle α with respect to the axis P.

Therefore, in the present embodiment, the discharge direction of the fluid flowing out of each of the discharge holes 2B is shifted from the direction of the discharge holes 2B in the same direction by a certain amount to flow out. Specifically, the raw water flows out from each discharge hole 2B in a direction opposite to the direction of the swirling flow F in the first space R1.
That is, the shower outflow member 2A forms a shower in the form of a swirling shower that flows out in a swirling flow in a direction opposite to the direction of the swirling flow F in the first space R1. This shower flow is a spacious wide-angle shower flow with a soft, handy feel.

  As shown in FIGS. 5 and 7, the switching unit CS is a member that arbitrarily switches the flow of the raw water to the purified water outflow unit 1, the shower channel W2, and the raw water channel W3. Therefore, by switching the switching unit CS, the purified water outflow unit 1, the shower outflow member 2A, and the raw water outflow unit 3 can be switched and used.

The supplementary description of the discharge hole 2B is provided.
The opening diameter (diameter) of the discharge hole 2B can be configured in a range usually used. However, it is preferable that the diameter of the opening of the discharge hole 2B be approximately 200 μm to 1000 μm. If it is too large, the shower outflow member 2A may cause a one-sided flow, or may not be able to form a clean shower flow, which is not preferable. On the other hand, if it is too large, it may not be possible to obtain a spacious wide-angle shower flow with a soft feel. By setting the opening diameter of the discharge hole 2B in the above range, it is possible to obtain a wide and wide-angle shower flow with a soft touch.

  The discharge hole 2B preferably has an upstream opening diameter of about 1.1 to 1.5 times the outflow side (outlet side) opening diameter. However, if the diameter of the opening on the upstream side is too large with respect to the outflow side (outlet side), a wide, wide-angle, soft hand-held shower flow may not be obtained. By setting the ratio of the opening diameter to the above range, it is possible to obtain a wide, wide-angle, soft hand-held shower flow.

  It is preferable that the length of the discharge hole 2B be approximately 200 μm to 1000 μm. However, if it is too long, it may not be possible to obtain a wide, wide-angle, soft, handy shower flow. By setting the length of the discharge hole 2B in the above range, it is possible to obtain a wide, wide-angle shower flow with a soft touch.
