Description

  The present invention relates to a water discharge device, and more particularly to a water discharge device that enables an automatic reciprocation operation that repeatedly changes the water discharge direction of a shower nozzle, a water spray nozzle, or the like.

  There is a growing need for shower systems and water discharge / spraying systems for relaxation and beauty and health promotion. In these applications, for example, there is an approach that promotes a massage effect or the like by modulating a water flow at a relatively high speed of several tens of hertz or more using a swirling flow or the like. On the other hand, for example, if the water discharge position and direction of the shower nozzle are repeatedly changed at a relatively slow speed of several hertz or less, for example, the water discharge is uniformly sprayed to a predetermined range of the human body to promote the relaxation effect, etc. Is possible.

  Similar needs exist widely in consumer equipment, industrial or agricultural applications, and require slow reciprocating motions for a variety of purposes such as cleaning, rinsing, cooling, humidification, pretreatment, and cultivation. It is said that.

  It is possible to use electric means such as motors and solenoids for reciprocal operation, but in order to install it in a system that discharges water in a bathroom, etc., measures for securing a power source, electric shock, and electric leakage are required. There are many problems to be solved in terms of cost and reliability.

  On the other hand, if the reciprocating operation can be realized by hydraulic power, electricity and lubricating oil are unnecessary, and improvement can be expected from many viewpoints such as initial cost, running cost, reliability, and maintainability.

  A combination of a piston and a four-way valve has been disclosed as a shower device that can move up and down (Patent Document 1). This shower device moves a shower head up and down via a wire by moving a piston provided in a cylinder up and down by water pressure. The switching of the upward / downward movement of the piston is performed by switching the water supply passage for the cylinder with a four-way valve.

  However, in the case of this shower apparatus, the cylinder and the four-way valve are provided separately, and the system is large and complicated. Moreover, since the flow path becomes long, there is room for improvement in that the pressure loss is large and the water discharge force is reduced.

JP-A-2-134119

In order to solve this problem, the present inventors have invented a water discharging device based on a novel idea and having a compact and simple structure and capable of repetitive rotating operation utilizing hydraulic power.

Moreover, when using such a water discharge device as a cleaning device in a factory or the like, if the water discharge angle range can be adjusted according to the size of the product to be cleaned, wasteful water discharge is reduced and efficient. Cleaning and high water-saving effect can be obtained.

The industrial merit is great.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic view illustrating a water discharge device according to this embodiment.

  The water discharge device 100 according to this embodiment includes a housing 102 and a water discharge cylinder 180 protruding from the housing 102. And the termination | terminus adjustment means 200 is provided in the surface orthogonal to the surface where the water discharging cylinder 180 in the housing 102 protrudes. A water discharge channel 182 is provided in the water discharge cylinder 180, and water discharge is obtained from the tip of the water discharge cylinder 180. A fan-shaped housing space is formed in the housing 102, and a core is provided in the housing space so as to be capable of rotating. The water discharge cylinder 180 is drawn out from the center of rotation of the core along the rotation axis of the core.

  The housing 102 is provided with two water inlets 112 and 114 on one surface orthogonal to the surface from which the water discharge cylinder 180 projects. A water inlet path from the water supply pipe 700 is connected to these water inlets 112 and 114 in parallel. That is, the water supply pipe 700 is bifurcated into two branch pipes having the same thickness and length, and these branch pipes are connected to the water inlets 112 and 114, respectively. A water supply valve 600 is provided upstream of the branch position in the water supply pipe 700. The water supply valve 600 adjusts the flow rate of the fluid flowing through the water supply pipe 700. When the water supply valve 600 provided in the water supply pipe 700 is opened, the fluid W such as water is supplied from the water supply pipe 700 to the water inlets 112 and 114 at substantially the same pressure. As a result, as shown by the arrow M, the water discharge can be discharged from the water discharge passage 182 while the water discharge cylinder 180 is reciprocatingly rotated about the central axis thereof as the rotation axis. Therefore, if the housing 102 is fixed and a nozzle, a shower head, or the like is provided at the tip of the water discharge cylinder 180, it can be used as a water discharge device that repeatedly changes the water discharge direction.

  In this embodiment, by providing the end adjusting means 200, the stroke of the reciprocating motion of the water discharge cylinder 180 can be adjusted. In the example shown in FIG. 1, the end adjusting means 200 is provided only on one side of the fan-shaped housing space, that is, the region on the water inlet 114 side in the housing 102, but a specific example will be described later. As described above, the end adjusting means 200 may be provided on both sides of the fan-shaped housing space, that is, both the region on the water inlet 114 side and the region on the water inlet 112 side.

Next, the specific example for implement | achieving the water discharging apparatus which concerns on this embodiment is demonstrated.
First, a first specific example will be described.
This specific example is an example in which a variable terminal 201 provided so as to protrude from the side wall of the housing into the housing space is provided as the terminal adjusting means 200. Further, this variable end is provided only on one water inlet side of the housing 102, that is, only one side of the fan-shaped housing space.

FIGS. 8A and 8B are cross-sectional views showing the operation of the termination adjusting means in the water discharge device of the first specific example, and FIG. 8A shows a variable termination as the termination adjusting means in the housing space. The state which does not protrude is shown, (b) shows the state which the variable termination | terminus protrudes in housing space.
In FIGS. 2 to 7, the variable termination is not shown for convenience of explanation.

  In the water discharging apparatus 100 according to this specific example, a housing 102 is provided. The housing 102 is formed so that the housing lids 104 and 105 are connected to both sides of the frame-shaped housing main body 103 so that the inside becomes hollow. Further, from one side of the housing 102, that is, the side where the housing lid 104 is disposed, the water discharge cylinder 180 protrudes through the housing lid 104. The water discharge cylindrical body 180 has a hollow structure having a water discharge flow path 182 inside, and the tip thereof is open and serves as a water discharge port. As will be described later, when water is introduced into the water inlets 112 and 114 provided in the housing 102, the water discharge cylinder 180 reciprocally rotates in the direction of the arrow M with the central axis as a rotation axis.

Next, the internal structure of the water discharge device 100 will be described.
As shown in FIGS. 3 to 6, the core 120 composed of the core main body 121 and the core lid 122 is disposed in the fan-shaped housing space formed by the housing main body 103 and the housing lids 104 and 105. It is housed so as to be rotatable as a central axis. That is, the core 120 is connected to a water discharge cylinder 180 penetrating through the housing 102, and rotates while dividing the fan-shaped housing space into a first pressure chamber 116 and a second pressure chamber 118. In FIG. 6, the first pressure chamber 116 is disposed on the right side as viewed from the core 120, and the second pressure chamber 118 is disposed on the left side in the diagram. Based on this, for convenience of explanation, the pressure chamber 116 side is also simply referred to as “right side” and the pressure chamber 118 side is also simply referred to as “left side” when viewed from the core 120.

  Water is introduced into the pressure chambers 116 and 118 from the water inlets 112 and 114, respectively. A seal 127 is provided at a sliding portion between the core 120 and the inner wall of the housing 102 for smooth sliding while maintaining liquid tightness. In addition, a seal 126 is provided on the sliding portion between the water discharge cylinder 180 and the housing 102 for the same purpose. The seals 127 and 126 are also made of a material that keeps fluid-tight and smoothly slides. For example, Teflon (registered trademark), NBR (nitrile rubber), EPDM (ethylene propylene rubber), and POM (polyacetal). Etc. can be used. Here, “liquid tightness” means that a state sufficient to cause a pressure difference between the first pressure chamber 116 and the second pressure chamber 118 (hereinafter also referred to as “left and right pressure chambers”) can be secured. Good.

Next, the structure of the core 120 will be described.
A core inner flow path 124 is formed inside the core 120, and the core inner flow path 124 communicates with a water discharge flow path 182 provided in the water discharge cylinder 180. In addition, the core 120 is provided with introduction ports 132 and 134 for communicating the core internal flow path 124 with the pressure chambers 116 and 118. Then, main valves 142 and 144 as valve bodies are provided so as to cross the inner core flow path 124. When the main valve 144 moves away from the core 120, the inlet 134 is opened, and when the main valve 142 moves away from the core 120, the inlet 132 is opened.

  As shown in FIG. 7, the left and right main valves 142 and 144 are connected by a connecting rod 149 and installed so as to be movable left and right through the inlets 132 and 134 provided in the core body 121 and the core lid 122. Has been. That is, the main valves 142 and 144 are installed so as to be movable left and right with a predetermined stroke with respect to the core 120. Ribs 143 are formed on the main valves 142 and 144, and the main valves 142 and 144 are configured to move coaxially with the introduction ports 132 and 134. When the main valves 142 and 144 move in directions away from the core 120, the groove portions 145 provided between the ribs 143 become the openings of the introduction ports 132 and 134, thereby forming a water channel.

  Further, the water discharge device 100 is provided with control means for controlling the operation of the main valves 142 and 144. As will be described later, the control means includes slide bars 146 and 148 and a leaf spring 160. When the core 120 reaches the end on the pressure chamber 116 side in the rotation region, the control means makes the pressure in the pressure chamber 116 higher than the pressure in the pressure chamber 118, and the core 120 rotates the rotation. The main valves 142 and 144 are actuated so that the pressure in the pressure chamber 118 becomes higher than the pressure in the pressure chamber 116 when reaching the end portion on the pressure chamber 118 side in the moving region. The degree of opening is changed. That is, the opening degree of the inlets 132 and 134 is set so that the magnitude relationship between the pressures in the pressure chambers 116 and 118 is reversed with the pressure in the pressure chamber 116 and the pressure in the pressure chamber 118 equal to each other. It is something to change.

  More specifically, when the core 120 reaches the end portion on the pressure chamber 116 side in the rotation region of the core 120, the flow resistance from the pressure chamber 116 to the core inner flow path 124 is The main valves 142 and 144 are actuated to change the opening degree of the inlets 132 and 134 so that the flow resistance from the chamber 118 to the core inner flow path 124 becomes larger, and the core 120 is moved in its rotation range. When the pressure chamber 118 end is reached, the flow resistance from the pressure chamber 118 to the core inner flow path 124 is larger than the flow resistance from the pressure chamber 116 to the core inner flow path 124. As described above, the main valves 142 and 144 are operated to change the opening degree of the inlets 132 and 134.

  In the present specification, the “opening degree” of the introduction port is a parameter that determines the flow path resistance of the water flowing between the introduction port and the valve body. For example, in the state shown in FIG. 6, the flow resistance of the flow path formed between the inlet 132 and the main valve 142 is the flow resistance of the flow path formed between the inlet 134 and the main valve 144. Greater than channel resistance. In this case, the opening degree of the introduction port 132 is smaller than the opening degree of the introduction port 134. The rotation area of the core 120 refers to a space where the core 120 actually rotates when the water discharge device 100 is operated. Further, the end of the rotation area refers to the end of the core 120 in the rotation direction.

  Next, a specific configuration of the control unit will be described. As described above, the control means includes the slide bars 146 and 148 and the leaf spring 160. The leaf spring 160 is supported by the core body 121 in a state in which both ends thereof are pressed toward each other, and a state in which the center portion is curved so as to protrude toward the pressure chamber 116 (right side) and pressure Two states, which are curved so as to protrude toward the chamber 118 (left side), are stable states. The slide bars 146 and 148 pass through the main valves 142 and 144 coaxially and are connected to each other with the leaf spring 160 interposed therebetween. The length of the slide bars 146 and 148 is longer than the length of the main valves 142 and 144. Therefore, the slide bars 146 and 148 are installed so as to be movable to the left and right with a stroke longer than the operation stroke of the main valves 142 and 144. ing.

  The operation of the main valves 142 and 144 for changing the opening degree of the introduction ports 132 and 134 is determined by the slide bars 146 and 148. That is, as shown in FIGS. 3 and 5, the left and right slide bars 146, 148 are connected with the compressed leaf spring 160 interposed therebetween, and the urging force toward the right end or the left end depending on the bending direction of the leaf spring 160. Receive. As a result, the slide bars 146 and 148 are biased by the leaf spring 160 to move relative to the core, and the movement of the slide bars 146 and 148 causes the main valves 142 and 144 to move relative to the core. It moves relatively, and the inlets 132 and 134 are controlled alternatively to either the fully open state or the fully closed state.

  And as shown to Fig.8 (a) and (b), the water discharge apparatus 100 is provided with the variable termination | terminus 201. FIG. The variable end 201 has a curved columnar shape extending along a part of the virtual circle 203, and is inserted into the side wall of the housing 102. By sliding with respect to this side wall, the circle 203 It is possible to move along. As a result, as shown in FIG. 8A, the variable end 201 extends outward from the housing 102 and does not protrude into the housing space, and as shown in FIG. 8B, the variable end 201 The position of the variable terminal 201 can be arbitrarily selected between the “inner position” where 201 is pushed into the housing space and protrudes into the housing space.

  Further, the center of the circle 203 coincides with the rotation center of the core 120, that is, the center of the water discharge cylinder 180, and the circle 203 passes through the distal end portions of the slide bars 146 and 148. As a result, when the core 120 reaches the end on the variable end 201 side in the rotation region, the tip of the slide bar 146 contacts the tip of the variable end 201.

  Further, as shown in FIG. 8A, the end surface of the variable end 201 that contacts the slide bar is inclined so as to be flush with the inner wall surface of the housing 102 when the variable end 201 is in the “outer position”. is doing. Thereby, when the tip of the slide bar 146 comes into contact with the tip of the variable terminal 201, the end surface of the variable terminal 201 is substantially perpendicular to the direction in which the slide bar extends. That is, the contact angle is almost vertical. Further, with such a structure, even when the variable end 201 is in the “inner position”, the variable end 201 and the slide bar 146 can be brought into substantially vertical contact.

  Furthermore, a seal mechanism 204 is provided at a portion of the side wall of the housing 102 that is in contact with the variable end 201 to ensure liquid-tightness while ensuring slidability of the variable end 201. As the sealing mechanism 204, for example, an O (O) ring made of rubber or resin can be provided. However, the seal mechanism 204 may be provided as necessary. For example, if the liquid tightness in the housing 102 is ensured by a sliding means provided between the housing 102 and the variable terminal 201, it is particularly necessary to provide the seal mechanism 204. There is no.

  Furthermore, the variable end 201 is provided with a lock mechanism (not shown) that prevents the variable end 201 from falling off inside or outside the housing 102. Further, the variable end 201 is provided with a gripping mechanism (not shown) for facilitating adjustment of the position of the variable end 201 by the user. The lock mechanism and the gripping mechanism may be shared by a single protrusion.

Hereinafter, the operation of the water discharging apparatus of this specific example will be described.
First, the operation of the portion other than the variable end in the water discharging device of this example will be described.
FIGS. 9A to 9C are schematic diagrams for explaining the operation of the water discharge device of this example. In FIGS. 9A to 9C, the variable termination is not shown for convenience.

  First, FIG. 9A shows a state in which the slide bars 146 and 148 are urged toward the left side by the action of the leaf spring 160. At this time, the main valves 142 and 144 are also urged to the left by the slide bar 146, so that the introduction port 132 is closed and the introduction port 134 is opened.

  When water is supplied to the water inlets 112 and 114 at substantially the same pressure in this state, the water introduced into the pressure chamber 118 from the water inlet 114 as indicated by the arrow A is transferred from the inlet 134 as indicated by the arrow C. It flows into the core inner channel 124 and flows out through the water discharge channel 182 as indicated by the arrow D. On the other hand, the water introduced into the pressure chamber 116 from the water inlet 112 as indicated by the arrow B has no outflow path because the inlet 132 is closed. For this reason, the pressure in the pressure chamber 116 is higher than the pressure in the pressure chamber 118. That is, by providing a difference in the opening degree of the inlets 132 and 134, a difference occurs in the flow path resistance, resulting in a pressure difference. As a result, the core 120 is pushed and rotated in the direction of the arrow M.

  When the core 120 rotates in the direction of the arrow M, the volume of the pressure chamber 116 increases, and the volume of the pressure chamber 118 decreases accordingly. For this reason, the water in the pressure chamber 118 is pushed out by the amount of water flowing into the pressure chamber 116 along the path indicated by the arrow B, and is included in the amount of water discharged from the flow path 182.

  When the core 120 continues to rotate and the slide bar 148 comes into contact with the inner wall of the housing 102 and is pressed against the core 120, the bending direction of the leaf spring 160 is reversed, as shown in FIG. As described above, the slide bars 146 and 148 are biased toward the opposite side. Then, when the slide bar 148 pushes the main valve 144, the main valves 142 and 144 also move to the right (clockwise direction). That is, the introduction port 132 is opened and the introduction port 134 is closed.

  In the state shown in FIG. 9B, the water introduced from the water inlet 112 into the pressure chamber 116 as indicated by the arrow B flows from the inlet 132 into the core inner channel as indicated by the arrow C. 124 and flows out through the water discharge channel 182 as indicated by the arrow D. On the other hand, as shown by the arrow A, the water introduced into the pressure chamber 118 from the water inlet 114 has no outflow path because the inlet 134 is closed. As a result, a pressure difference is generated in the pressure chambers 116 and 118, and the core 120 starts to rotate toward the right side as indicated by an arrow M.

  When the core 120 further rotates, the slide bar 146 moves to a position where it abuts against the inner wall of the housing 102 as shown in FIG. When the core 120 is further rotated from this state and the slide bar 146 is pushed against the core 120, the bending direction of the leaf spring 160 is reversed and biased to the opposite side. Then, similarly to the state shown in FIG. 9A, the introduction port 132 is closed and the introduction port 134 is opened, and the core 120 starts to rotate toward the left side.

Next, the operation of the control means in this example will be described in more detail.
FIGS. 10A to 10D are schematic views for explaining the operation of the control means in this example.
That is, FIG. 10A shows a state in which the leaf spring 160 is curved so that the right side is convex and the slide bars 146 and 148 are urged in this direction. At this time, the introduction port 132 is closed by the main valve 142 and the introduction port 134 is opened by the main valve 144.

  When the core 120 is rotated to the right in this state, the slide bar 148 comes into contact with the inner wall of the housing 102 as shown in FIG. Since a pressure difference is acting on the core 120, the core 120 is further rotated to the right in a state where the slide bar 148 is in contact with the inner wall of the housing, and the state shown in FIG. That is, the relative position between the core 120 and the slide bar 148 is changed by overcoming the biasing force of the leaf spring 160, and the slide bar 148 is pushed against the core 120. As a result, the leaf spring 160 is also pushed and deformed to the left side to be in a substantially S-shaped state as illustrated in FIG. At this time, a pressure difference acts on the main valves 142 and 144 similarly to the core 120, and the open / close state of the inlets 132 and 134 is not changed.

Thereafter, when the slide bar 148 is further pushed against the core 120 by further rotating the core 120, the bending direction of the leaf spring 160 is reversed to the left as shown in FIG. The slide bars 146 and 148 are urged to the left side.
Then, as shown in FIG. 10D, the main valves 142 and 144 are moved to the left by the urging force of the leaf spring 160, the introduction port 132 is fully opened, and the introduction port 134 is fully closed.

  As described above, in this specific example, the direction of bending of the compressed leaf spring 160 is appropriately reversed by the slide bars 146 and 148, and the main valves 142 and 144 are operated by using the biasing force, thereby introducing the inlet port. Alternatively, 132 and 134 are controlled to be either fully open or fully closed. That is, by using the urging force of the leaf spring 160, the opening difference between the left and right inlets 132 and 134 is reliably formed for the reversal of the core 120.

  The mechanism of this example that controls the main valves 142 and 144 via the slide bars 146 and 148 plays an extremely important role for the smooth operation of the water discharge device 100. In other words, the compressed leaf spring 160 is in a stable state when bent to the right or left, but as shown in FIG. 10B, it becomes a metastable neutral state near the middle of these stable states. There is. In this state, the leaf spring 160 does not generate much urging force to the left or right. Therefore, in this state, if the opening degree of the inlets 132 and 134 becomes substantially the same, water flows from the inlets 132 and 134 on both sides of the core, so that there is no pressure difference and the rotation of the core 120 The movement stops. That is, if the timing for starting the movement of the main valves 142 and 144 is earlier than the timing for reversing the leaf spring 160, the operation of the core 120 may stop.

  On the other hand, according to the present specific example, the slide valves 146 and 148 are provided, and the strokes are adjusted as appropriate, so that the main valves 142 and 144 in the metastable neutral state as shown in FIG. Is still not moved, and the core 120 is kept under pressure by applying pressure. The main valves 142 and 144 can start to move when the leaf spring 160 starts to reverse beyond this neutral state. That is, the movement start timing of the main valves 142 and 142 can be synchronized with the reversal timing of the leaf spring 160.

  In other words, the leaf spring 160 is reversed before the opening difference sufficient to rotate the core 120 disappears, and the main valves 142 and 144 are moved via the slide bars 146 and 148 by the reversal force (biasing force). The opening degree difference between the introduction ports 132 and 134 can be reversed to an opening degree difference sufficient to rotate the core 120 in the reverse direction.

  In this way, it is possible to solve the problem that the opening degree of the introduction ports 132 and 134 becomes substantially equal when the leaf spring 160 is in a neutral state, and the core 120 stops, and smooth repetitive motion can be realized. .

  Further, in this case, even when the water discharge is started from the state where the core 120 is stopped near the middle of the rotation stroke, the main valves 142 and 144 are controlled by the leaf spring 160 at the time of water discharge start. Thus, one of the introduction ports 132 and 134 is alternatively open, and a pressure difference is formed on both sides of the core 120 so that a stable initial operation can be started. That is, the state where the opening degree of the introduction port 134 is larger than the opening degree of the introduction port 132 and the state where the opening degree of the introduction port 132 is larger than the opening degree of the introduction port 134 can be held alternatively. can do.

  Next, operation | movement of the variable termination | terminus 201 in the water discharging apparatus 100 which concerns on this example is demonstrated. As described above, by providing the variable end 201 on one side wall of the housing 102, the slide bar 146 contacts the variable end 201 when the core 120 reaches the end on the pressure chamber 116 side in the rotation region. The main valves 142 and 144 are moved in contact with each other. That is, the position where the slide bar 146 contacts the variable end 201 is the end position of the reciprocating motion of the core 120. Therefore, the stroke of the reciprocating rotational movement of the core 120 can be changed by adjusting the position of the variable terminal 201, and can be stopped by further narrowing the stroke. In this way, the variable end 201 can regulate the rotation range of the core 120.

  More specifically, as shown in FIG. 8A, if the variable terminal 201 is positioned at the outer position, the end surface of the variable terminal 201 coincides with the inner wall surface of the housing 102. The area is the widest. At this time, the rotation angle range of the water discharge cylinder 180 is the largest. On the other hand, as shown in FIG. 8B, if the variable terminal 201 is positioned at the inner position, the rotation range of the core 120 becomes the narrowest. At this time, the rotation angle range of the water discharge cylinder 180 is the smallest. And the rotation angle range of the water discharge cylinder 180 can be arbitrarily adjusted by arrange | positioning the variable termination | terminus 201 in the arbitrary positions between an outer position and an inner position.

  As described above, in this specific example, the rotation angle range of the water discharge cylinder 180 can be arbitrarily controlled by adjusting the position of the variable end 201. In addition, the direction of rotation of the core 120, the movable direction of the main valves 142 and 144, the movable direction of the slide bars 146 and 148, and the biasing direction of the leaf spring 160 are made substantially the same, so that the way of working force is wasted. Therefore, the moving force of the core having a large pressure receiving area can be effectively used, and smooth and stable operation is possible. That is, a control operation for reversing the magnitude relationship between the opening degrees of the introduction ports 132 and 134 for reversing the core 120 by linking the movement operation of the core 120 and the opening degree control operation is reliable and easy. And a simple and compact valve body and control means. Thereby, the magnitude relationship of the opening degree difference of the inlet is appropriately reversed according to the rotation of the core 120, and the core 120 can be operated repeatedly left and right.

  That is, in order to move the core 120, a difference in opening degree of the introduction ports 132 and 134 may be provided to generate a pressure difference necessary for rotation. Similarly, when the rotation direction of the core 120 is reversed, the magnitude relationship between the opening degrees of the introduction ports 132 and 134 may be reversed by the control means. For example, the reversing operation can be performed by changing the ratio of the opening degree of the introduction ports 132 and 134 from 70:30 to 30:70 by the control means. Furthermore, if the opening degree is changed from 100: 0 to 0: 100 by the control means, the most reliable and stable reversing operation is possible.

  In addition, according to this specific example, mechanical power such as electricity is not required, and smooth reciprocal reversal motion is possible only with supply pressure of water or the like, and measures such as installation of a power source, electric shock, or electric leakage are not required. In addition, smooth operation is possible without being affected by disturbances such as electromagnetic noise.

  Furthermore, according to this example, the main valves 142 and 144 and the control means are provided attached to the core 120, so that an external four-way valve, for example, is not required, and smooth reciprocation is achieved with a simple configuration. Reversing motion can be realized. As a result, downsizing becomes easy and the flow path becomes simple, so that pressure loss can be suppressed, and it is advantageous in that a water discharge amount and water discharge pressure can be secured. Further, since the main valves 142 and 144 and the control means are built in the housing 102, a smooth operation strong against disturbance can be realized. Furthermore, regarding water supply, it is only necessary to branch from the same water supply source and connect it to two water inlets, and the workability is excellent. Furthermore, since the water channel is formed inside the rotating core and the water discharge cylinder, it is possible to change the water discharge angle simply by connecting various nozzles or spouts to the tip of the water discharge cylinder. The workability is also excellent in that no special connection member is required. In particular, the water discharge device of this specific example is advantageous in that it is excellent in workability even when it is installed “retrofitting” on existing equipment indoors or outdoors.

  The thrust obtained by the rotation operation is determined by the product of the water pressure applied to the core 120 and the pressure receiving area of the core. Therefore, if the pressure receiving area of the core 120 is increased, a large thrust corresponding to the pressure receiving area can be obtained.

  In this specific example, when the core 120 is reversed, the slide bars 146 and 148 are brought into contact with the inner wall or the variable end of the housing, but the present invention is not limited to this. For example, magnets are provided on the slide bars 146 and 148, while magnets are also provided on the inner wall of the housing and the tip of the variable end, and the slide bars 146 and 148 are attached to the housing by utilizing the repulsive force acting between them. It is also possible to stop relatively. In this case, in the state corresponding to FIGS. 10A to 10C, the slide bars 146 and 148 do not come into contact with the inner wall of the housing 102 and the tip of the variable end, and the repulsion of the magnet (not shown). The force is in a state of being separated from the inner wall of the housing 102 and the tip of the variable end by a predetermined distance. In this way, the core 120 can be reversed without contact. Thereby, for example, the reciprocating motion of the core can be smoothed, or the slide bar can be prevented from coming into contact with the housing and generating sound. In this case, the rotation range of the core refers to a space where the core actually rotates, not a space where the core should have rotated without a magnet.

Next, a modification of this example will be described. In this modification, a magnet is used as the control means for reversing the magnitude relationship between the opening degrees of the introduction ports 132 and 134, instead of the leaf spring and the slide bar as in the first specific example described above.
FIGS. 11A to 11D are schematic views showing the operation of the control means in this modification.

  FIG. 11A shows a state in which the core 120 rotates from the left side toward the right side and the main valve 144 is in contact with the inner wall of the housing 102. In this modification, the core 120 is provided with a magnet 170, and the housing 102 is provided with a magnet 174. In this modification, in order to use the attractive force between the magnet 170 and the magnet 174, one of the magnets 170 and 174 may be replaced with a ferromagnetic material.

  In the state shown in FIG. 11A, the force due to the pressure difference acts on the core 120, so that the core 120 further rotates to the right. That is, the core 120 rotates further to the right in a state where the main valve 144 is in contact with the housing 102 and fixed in the moving direction.

  Finally, the state shown in FIG. In this state, since the opening degree of the inlets 132 and 134 is substantially the same, a pressure difference due to a difference in flow path resistance does not occur. However, at this time, the core 120 can be further pulled to the right side by the attractive force acting between the magnet 170 and the magnet 174.

  In this case, depending on the value of the sliding resistance of the core 120, the core 120 may stop before the state shown in FIG. In such a case, it is desirable to attract the core 120 by an attractive force acting between the magnet 170 and the magnet 174 in the state between FIG. 11A and FIG.

  When the core 120 is drawn to the right side by the attractive force of the magnet from the state shown in FIG. 11B, the core 120 reaches the end of its rotation area and is introduced as shown in FIG. 11C. A state is formed in which the opening degree of the mouth 132 is larger than the opening degree of the introduction port 134. Then, a difference occurs in the flow path resistance of these inlets 132 and 134, and a pressure difference is generated. That is, the pressure on the right side of the core 120 becomes higher, and the core 120 starts to move to the left side. That is, the core 120 can be reversed by reversing the magnitude relationship of the opening degree difference between the introduction ports 132 and 134.

  At this time, the pressure difference also acts on the main valve 144, and a force in the direction of closing the main valve 144 works. As a result, as shown in FIG. 11D, the main valve 144 is completely closed, and the pressure on the right side of the core 120 increases to the maximum value. That is, the maximum driving force to the left is obtained after the core 120 is inverted.

  As described above, if the core 120 can be drawn to the state shown in FIG. 11C by the attractive force acting between the magnet 170 and the magnet 174, the difference in opening between the inlets 132 and 134 is large or small. The relationship can be reversed and the core 120 can be reversed. That is, the core 120 can be reciprocally rotated within the housing 102.

  In this case, the core 120 needs to overcome the attractive force of the magnet after the reversal and rotate. That is, it is desirable to appropriately set the balance between the force acting on the core 120 due to the pressure difference and the attractive force obtained by the magnet.

  In this modification, the surfaces of the main valves 142 and 144 (contact surfaces with the housing 102) protrude in a curved shape so that a gap is generated even when the main valves 142 and 144 are in contact with the housing 102. Thus, by reducing the contact area with the housing 102, the pressure difference received by the valve body can be effectively utilized, and the valve body can be smoothly reversed so that the degree of opening is reversed.

  In this modification, the main valves 142 and 144 are brought into contact with the inner wall of the housing 102 when the core 120 is reversed, but the present invention is not limited to this. For example, magnets are provided on the main valves 142 and 144, while magnets are also provided on the inner wall of the housing 102, and the main valves 142 and 144 are moved relative to the housing 102 by utilizing a repulsive force acting between them. It can also be stopped. That is, in this case, in the state corresponding to FIGS. 11A to 11C, the main valves 142 and 144 do not contact the inner wall of the housing 102, and the repulsive force of the magnet (not shown) causes the housing 102 to It will be in the state away from the inner wall by a predetermined distance. In this way, the core can be reversed without contact.

Next, a second specific example of the present embodiment will be described.
FIG. 12 is a cross-sectional view showing the water discharging device according to this example.
As shown in FIG. 12, in the water discharge device 100 a according to this specific example, the variable end 201 is located on both sides of the fan-shaped housing space in the housing 102, that is, the region on the water inlet 114 side in the housing 102 and the water inlet 112 side. It is provided in both areas. The two variable terminations 201 are movable independently of each other. Configurations other than those described above in this specific example are the same as those in the first specific example described above.

  In this specific example, if the amount of protrusion into the housing space is made equal between the two variable ends 201, the rotation angle range can be adjusted without changing the rotation center of the water discharge cylinder 180. On the other hand, if the amount of protrusion into the housing space is different on the left and right, the rotation angle range can be adjusted while adjusting the rotation center of the water discharge cylinder 180 to an arbitrary position. In addition, by providing the variable terminal 201 at both ends of the housing space, each variable terminal 201 can be shortened if the adjustment range of the rotation angle range is the same as compared with the case where the variable terminal 201 is provided only on one side of the housing space. it can. Thereby, the whole water discharging apparatus can be comprised compactly. The operations and effects other than those described above in this specific example are the same as those in the first specific example described above.

Next, a third specific example of the present embodiment will be described.
FIG.13 and FIG.14 is sectional drawing which shows the water discharging apparatus which concerns on this example.
This specific example is an example in which a control magnet is provided as the termination adjusting means 200.
In the case of this specific example, a control magnet 206 is provided on the side wall of the housing 102 facing the slide bar 146 in the water discharge device 100b. A magnet 208 is built in the slide bar 146. In the case of the specific example shown in the figure, the magnet 208 built in the slide bar 146 is on the right side, that is, the control magnet 206 side has an N pole and the left side has an S pole. On the other hand, the control magnet 206 can switch the magnetic pole of the part corresponding to the slide bar 146 by the rotation mechanism 207, for example. That is, in the state shown in FIG. 13, the magnetic poles of the control magnet 206 corresponding to the slide bar 146 are N poles. Further, by rotating the control magnet 206 halfway by the rotation mechanism 207 from this state, the magnetic pole of the control magnet corresponding to the slide bar 146 becomes the S pole as shown in FIG. As described above, the stroke of the water discharge cylinder 180 can be changed by switching the magnetic poles of the control magnet 206.

  That is, in the state shown in FIG. 13, a repulsive force acts between the N pole of the control magnet 206 and the N pole of the magnet 208 built in the slide bar 148. Therefore, when the core 120 rotates rightward (clockwise), the slide bar 148 is pushed by the repulsive force of these magnets before the tip of the slide bar 148 comes into contact with the inner wall of the housing 102. Thus, the main valve moves, the inlet 134 is closed, and the inlet 132 is opened. FIG. 13 shows a state after the opening degree of the introduction port is switched in this way. Thereafter, the core 120 is rotated to the left side (counterclockwise). That is, in the state shown in FIG. 13, the stroke of the reciprocating motion of the core 120 is relatively short.

  On the other hand, in the state shown in FIG. 14, an attractive force acts between the south pole of the control magnet 206 and the north pole of the magnet 208 built in the slide bar 148. Therefore, when the core 120 rotates to the right (clockwise), the main valve 144 does not move and the introduction port 134 remains open until the tip of the slide bar 148 contacts the inner wall of the housing 102. . That is, in the state shown in FIG. 14, the stroke of the reciprocating motion of the core 120 is relatively long.

  Furthermore, the stroke can be adjusted by rotating the rotation mechanism 207 so that the control magnet 206 is in a state between the state shown in FIG. 13 and the state shown in FIG. That is, the magnetic force from the control magnet 206 is adjusted, and a repulsive force weaker than the state shown in FIG. 13 or an attractive force weaker than the state shown in FIG. 14 is applied to the magnet 208 built in the slide bar 148. Can act. In this way, it is possible to obtain a stroke longer than the stroke in the state shown in FIG. 13 and shorter than the stroke in the state shown in FIG. As shown in FIG. 13, when the slide bar 148 is pressed without contact, the water pressure applied to the tip surface of the slide bar 148 can be effectively used as part of the reversal force.

  Also in this specific example, as described above with reference to FIG. 12, the end adjusting means 200 can be provided on both sides of the housing space. That is, a magnet can be incorporated in the slide bar 148, and a control magnet can be provided on the side wall portion of the housing 102 opposite to the magnet. Also in this case, the left and right end adjusting means 200 may be controlled independently or linked and controlled.

Next, an application example of the water discharge device according to the present embodiment will be described.
First, a first application example will be described.
FIG. 15 is a schematic diagram illustrating a first application example of the present embodiment.

  In this application example, a water discharge device 100 according to the present embodiment is provided. As the water discharge device 100, for example, the water discharge device according to any specific example of the present embodiment can be used. The water discharge device 100 is installed on a wall surface 900, and a shower nozzle 820 is mounted on a water discharge cylinder. In addition, in this specific example, the drive part of the water discharging apparatus may be provided on both sides of the shower nozzle 820, or the drive part may be provided only on one side and the other may be a simple bearing part.

  In this application example, the shower nozzle 820 reciprocates as indicated by the arrow M, so that shower-like water discharge can be sprayed in a wide range with a compact shape. For example, by using this water discharge device in a bathroom, the user can take a shower efficiently without hand, which is convenient. In addition, it can be expected to have a massage effect and relaxation effect by stimulating showers that fluctuate repeatedly.

  On the other hand, when the shower nozzle 820 is fixed, the housing of the water discharge device 100 rotates, and this operation can be used for massage and the like. That is, a massage effect such as “Momihogushi” can be obtained by pressing the body against the reciprocatingly rotating housing.

  The water discharge device 100 incorporates termination adjusting means (not shown), and an operation unit 300 of the terminal adjustment means is attached to the outer surface of the housing of the water discharge device 100. Then, when the user operates the operation unit 300, the rotation angle range of the shower nozzle 820 can be adjusted. Thereby, the area | region to discharge can be selected according to a user's physique and liking. As a result, user satisfaction can be improved, wasteful water discharge can be reduced, and cleaning efficiency and massage efficiency can be increased.

  For example, when such a water discharge device is installed on a wall surface 900 such as a bathroom and used as a body shower, the direction of water discharge can be periodically changed. There is no need to make it easier to use. Moreover, it is also possible to obtain a relaxation effect by applying spray-like water discharge over a wide range, and the usability is improved.

  In these cases, for example, the range in which water discharge is desired varies depending on the physique of the user. On the other hand, according to this application example, the angle range can be adjusted according to the user's physique and preference by operating the operation unit 300 of the terminal adjusting means, and the usability is improved and the effect on the target portion is efficiently performed. By doing so, a water-saving effect can also be obtained.

  Further, it is also possible to reduce and stop the rotation angle range by controlling the terminal adjusting means. Accordingly, the water can be discharged while being fixed at a user's favorite position. For example, when it is desired to wash the hair, water can be discharged intensively at that portion, and a higher cleaning effect can be obtained.

  In addition, although the example which installed the shower apparatus in the wall surface 900 was represented in FIG. 15, you may install in the edge of a bathtub, for example besides this. FIG. 15 shows an example in which the unit is installed horizontally with respect to the wall surface 900, but the same operation and effect can be obtained even when installed vertically.

Next, a second application example of this embodiment will be described.
FIG. 16 is a schematic diagram illustrating this application example.
In this application example, the water discharge device 100 according to the embodiment of the present invention is installed on a horizontal plane 920, and a water discharge nozzle 830 is attached to the tip of a water discharge cylinder projecting upward. When a fluid such as water is supplied from the water supply pipe 700, the water discharge nozzle 830 spreads the water discharge over a wide range while reciprocating in the direction of the arrow M. This water discharger is suitable for use in applications such as spraying water to plants in a garden or field, or watering a ground.

In this application example as well, the water discharge angle range can be adjusted by the action of the end adjusting means 200. Thereby, a watering area | region can be selected arbitrarily according to the width of a ground.
That is, it is possible to realize a water discharge device that is small and compact, has excellent portability, does not require electric power, is resistant to disturbance, can adjust the watering range according to the size of the ground, and has a high water-saving effect. Moreover, this water discharging apparatus is excellent in “retrofitability” in that it can be driven simply by connecting to a hose or the like as a water supply pipe.

As mentioned above, with reference to FIG.15 and FIG.16, although the application example of the water discharging apparatus which concerns on this embodiment was shown, the application example of this embodiment is not limited to these.
For example, by installing the water discharging device according to the present embodiment in a sink or the like, it is possible to widen the water discharging range and increase the cleaning efficiency when the user is washing hands or tableware. In addition, an easy-to-use hand-washing machine can be provided for the elderly and the disabled. At this time, by operating the terminal adjusting means, it can be operated within an angle range according to the user's preference and the object. For example, when washing dishes, etc., there are objects of various sizes from large pots to small dishes, but by adjusting the angle range according to each size, water can be discharged efficiently. Can be applied to the object, and the cleaning efficiency can be increased to save water. Furthermore, the angle range can be greatly narrowed, and water can be discharged while being fixed at a user's favorite position. For example, it is possible to efficiently use the water discharge device when it is desired to wash a specific part intensively or when it is desired to draw water, etc., and to provide a user-friendly water discharge device.

  Moreover, the water discharging apparatus of this embodiment can also be used for stirring and mixing. For example, when water is discharged while rotating the nozzle in a state where the water discharge device of the present embodiment is submerged in the liquid tank, the liquid in the liquid tank can be stirred and mixed. Further, stirring and mixing can be performed even if the nozzle is fixed in the liquid tank and the housing is rotated. Also in this case, the state of agitation and mixing can be selected by operating the terminal adjusting means to adjust the rotation angle range of the water discharge.

  Furthermore, the application field of the water discharger according to the present embodiment is not limited to a bathroom, hand-washing, or a kitchen. For example, when the water discharge device of the present invention is incorporated in an automobile cleaning device, the water discharge range can be adjusted according to the size of the vehicle, a water-saving effect can be obtained without sprinkling water more than necessary, and the surroundings are not wetted. It is possible to obtain the effect that the process is completed. Furthermore, by incorporating such a water discharge device into a cleaning device at various industrial sites including semiconductors, food, medical, paper pulp, automobiles, etc., for example, semiconductor wafers, liquid crystal panel substrates, Various raw materials, materials, parts, etc. can be cleaned efficiently. In this case as well, the water discharge range can be adjusted according to the size of the object, so a water-saving effect is obtained, and it is not necessary to supply power or lubricating oil, and no electromagnetic noise is generated. In addition, various effects such as hygienic and excellent maintainability are obtained without being affected by noise. Moreover, since the rotation angle, that is, the water discharge range can be adjusted, it is particularly advantageous in that it can be adapted to the size of the object when retrofitted to various systems.

The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to these specific examples.
That is, even if a person skilled in the art adds a design change to any of the elements constituting the water discharge device of the present invention, any element having the gist of the present invention is included in the scope of the present invention.

For example, even if a person skilled in the art appropriately changes the shape or arrangement of the water discharge device and the water discharge nozzle of the water discharge device, the terminal adjustment means, and other components, etc., as long as the gist of the present invention is included. Are included within the scope of the present invention.
In addition, it is only necessary that the water inlets corresponding to the left and right pressure chambers are formed with respect to the water inlets, for example, a flow path branched in the housing is formed and connected to each water inlet, and the water inlet connection to the housing is made. There may be only one mouth, and this can simplify the piping.
