Description

  The present invention relates to a fluid control valve.

  Conventionally, as a fluid control valve for flow control and flow mixing, for example, a mixing faucet for mixing hot water and water for the purpose of supplying hot water at an appropriate temperature, a hot water inflow passage is provided at regular intervals in the circumferential direction of the cylinder portion. And a water inflow channel, a valve housing having an outflow channel at one end in the axial direction, and a pivotable fit in the cylinder portion of the valve housing, so that the hot water inflow channel and the water inflow channel rotate at a constant rotation. A valve body having a hot water inlet hole and a water inlet hole that can be matched at each timing, an outlet hole that coincides with the outflow passage at one end in the axial direction, and an electric motor that rotates the valve body forward and backward (See FIGS. 6 and 7 of Patent Document 1).

  When the hot water inlet hole coincides with the hot water inflow passage by the forward rotation of the valve body, hot water is supplied from the outlet hole to the outflow passage. When the water inlet hole coincides with the water inflow passage by the reverse rotation of the valve body, Is supplied from the outlet hole to the outflow passage, and the hot water inlet hole coincides with a part of the hot water inflow passage, and the water inlet hole coincides with a part of the water inflow passage at approximately the middle of the forward / reverse rotation of the valve body. Then, a mixture of hot water and water is supplied from the outlet hole to the outflow path.

  On the other hand, in a bathtub (so-called bubble jet (registered trademark) bath) equipped with a fine bubble generating device that jets bath water containing fine bubbles into the bathtub from the injection nozzle, the injection nozzle is a fluid such as a pump or a valve. By controlling the supply means, it is possible to change the strength of the jetting timing and jetting flow, but it has only been possible to jet in a spot in a certain direction for the bather.

  Therefore, the present applicant has proposed an injection flow deflection nozzle that can swing the injection flow. The jet flow deflection nozzle has at least two fluid passage jet ports facing one jet opening, and the jet ports are arranged so that the jet flows collide in an intersecting state. Is connected to a fluid supply means whose fluid supply amount is adjustable.

  In this jet flow deflection nozzle, at least two jet ports are arranged so that the jet flows collide in an intersecting state, so that the jet flow can be swung (deflected) simply by adjusting the amount of fluid supplied from the fluid supply means. ).

For example, if the jet flow deflection nozzle is attached to the bathtub and the bath water is jetted, the jet flow is swung (deflected) up and down with respect to the back of the bather, for example, so A feeling can be obtained.
Japanese Patent No. 2950162

  In the jet deflection nozzle or the like according to the applicant's proposal as described above, fluid supply means that can be supplied while adjusting the fluid supply amount to each fluid passage, that is, while continuously changing the outflow path, There is a need for a fluid control valve that can linearly increase or decrease the flow rate of the outflow path.

  The present invention has been made in order to meet the above-described demand, and an object thereof is to provide a fluid control valve capable of linearly increasing or decreasing the flow rate of each outflow path while continuously changing the outflow path.

  In order to solve the above-mentioned problems, the first means of the present invention is a valve having a plurality of outflow passages at a constant interval in the circumferential direction of the cylinder portion and having an inflow passage at one end in the axial direction. A valve body having an outlet hole that is rotatably fitted in a cylinder portion of the valve housing and can be matched across adjacent outlets, and an inlet hole that matches the inflow path at one end in the axial direction; The present invention also provides a fluid control valve comprising an electric motor that continuously rotates the valve body.

  The second means of the present invention includes a valve housing having a plurality of outflow passages with a constant interval in the axial direction of the cylinder portion and having an inflow passage at one end portion in the axial direction, and rotating into the cylinder portion. An outlet hole that can be fitted and formed corresponding to each of the outflow paths and that can coincide with each of the outflow paths at a fixed rotation timing and an inlet hole that coincides with the inflow path at one end in the axial direction. A fluid control valve comprising a valve body and an electric motor that continuously rotates the valve body is provided.

  According to the first means of the present invention, when the valve body is continuously rotated by the electric motor and the outlet hole completely coincides with a certain outflow path, the fluid supply amount to the outflow path becomes maximum, and thereafter the rotation is performed. The fluid supply amount to the rear outflow passage in the rotational direction gradually decreases and the fluid supply amount to the front outflow passage in the rotational direction gradually increases according to the degree of the outlet hole matching the front outflow passage in the direction. To come.

  That is, the fluid supply amount in the outflow passages in the rear and front of the rotation direction is 100% and 0%, 90% and 10%, 80% and 20%, 70% and 30%, 60% and 40%, 50% and 50 %, 40% and 60%, 30% and 70%, 20% and 80%, 10% and 90%, 0% and 100%, etc. Can be increased or decreased linearly.

  Therefore, the fluid control valve used for the jet deflection nozzle arranged so that the jets of the at least two fluid passages face one jet opening and the jets collide in an intersecting state. In this case, for example, the fluid supply amount to the ejection port corresponding to the rear outflow passage in the rotation direction is adjusted to 100%, and the fluid supply amount to the ejection port corresponding to the front outflow passage in the rotation direction is adjusted to 0%. For example, the jet flow is jetted in one oblique direction only from the jet outlet corresponding to the rear outflow passage in the rotation direction, and conversely, the fluid supply amount to the jet outlet corresponding to the front outflow passage in the rotation direction is rotated by 100%. If the fluid supply amount to the ejection port corresponding to the outflow path at the rear of the direction is adjusted to 0%, the jet flow is ejected diagonally in the other direction only from the ejection port corresponding to the outflow path at the front of the rotation direction, Fluid to the jets corresponding to the rear and front outflow paths in the direction of rotation If the supply amount is adjusted in increments of 50%, the jet flow is jetted in one diagonal direction and the other from the rear and front jet ports in the rotational direction, and is deflected straight from the diagonal direction by colliding at the intersection. Be injected.

  Accordingly, the amount of fluid supplied to the jet outlets corresponding to the rear and front outflow paths in the rotation direction is varied between 90% and 10%, 80% and 20%, 70% and 30%, 60% and 40%. If adjusted, the jet flow in one diagonal direction is gradually deflected in the direction of the collision at the intersection and ejected, and then the fluid is supplied to the ejection ports corresponding to the rear and front outflow paths in the rotational direction. If the amount is adjusted so as to fluctuate between 40% and 60%, 30% and 70%, 20% and 80%, 10% and 90%, the jet flow in the straight direction is gradually slanted by the collision at the intersection. It is deflected in the direction and injected.

  In this way, the jet flow from the jet deflection nozzle can be swung (deflected) simply by adjusting the amount of fluid supplied from the fluid control valve. If jetting is performed, a feeling of sideburn due to massage can be obtained by swinging (deflecting) the jet flow vertically with respect to the back of the bather, for example.

  According to the second means of the present invention, when the valve body is continuously rotated by the electric motor and the outlet hole completely coincides with a certain outflow path, the fluid supply amount to the outflow path becomes maximum, and thereafter the rotation is performed. The fluid supply amount to the rear outflow passage in the rotational direction gradually decreases and the fluid supply amount to the front outflow passage in the rotational direction gradually increases according to the degree of the outlet hole matching the front outflow passage in the direction. To come.

  That is, as with the first means of the present invention, if the amount of fluid supplied from the fluid control valve is adjusted and the jet deflection nozzle is attached to the bathtub to inject the bath water, For example, when the jet stream is swung (deflected) in the vertical direction with respect to the back, a feeling of sideburn due to massage can be obtained.

  Moreover, since the number of outlet holes facing the respective outflow passages are formed in the valve body, the opening angle can be arbitrarily enlarged or reduced for each outlet hole.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  A flange portion 2a is formed at the upper end portion of the nozzle body 2, and a packing 8a is attached to the upper surface of the flange portion 2a.

  A cylindrical attachment member 10 is provided, a flange portion 10a is formed at the upper end of the attachment member 10, and a packing 8b is attached to the lower surface of the flange portion 10a.

  As shown in FIGS. 7 (a) and 7 (b), when the jet flow deflection nozzle 1 is attached to the G position facing the back of the bather N of the bathtub 25, the fluid passage portion 4 is positioned above the bathtub 25. In the state where the fluid passage portion 5 is located at the lower side of the bathtub 25, the packing of the flange portion 2a of the nozzle body 2 is provided on the outer peripheral portion of the mounting hole 25b formed in the side wall 25a of the bathtub 25 as shown in FIG. Apply 8a.

  And the sleeve part 10b of the attachment member 10 is penetrated to the attachment hole 25b from the inside of the bathtub 25, and the outer periphery external thread (not shown) of the sleeve part 10b is set to the inner periphery internal thread (not shown) of the injection opening 3 of the nozzle body 2. The nozzle body 2 can be attached to the side wall 25a of the bathtub 25 in a watertight state with the attachment member 10 while the packing 8b of the flange portion 10a is applied to the inner peripheral portion of the attachment hole 25b.

  In the sleeve portion 10b of the mounting member 10 located in the injection opening 3 of the nozzle body 2, the injection opening member 12 is fitted, and the lower end portion is positioned at the bottom portion 2b of the nozzle body 2, The outer peripheral male screw (not shown) of the cap member 13 is screwed into the inner peripheral female screw (not shown) of the mounting member 10, so that the injection opening member 12 is pressed by the cap member 13, and the inside of the injection opening 3 of the nozzle body 2. To be mounted on.

  Guidance ports 12a and 12b connected to the ejection ports 4b and 5b of the nozzle body 2 are formed in the lower portion of the ejection opening member 12, and the nozzle body is disposed under the guidance ports 12a and 12b. Communication holes 12c are formed in the two space portions 7 respectively. A pair of slit forming portions 12d rising from both sides of the guide ports 12a and 12b are formed on the upper portion of the ejection opening member 12, and a slit 12e is formed between the slit forming portions 12d. The ejection opening 3 is formed in a slit shape.

  The slit 12e is set to face the bathtub 25 in the vertical direction when the slit 12e is attached to the G position facing the back of the bather N in the bathtub 25.

  The G position (the same applies to the H, I, and J positions described below) facing the back of the bather N in the bathtub 25 is located at two symmetrical positions on the back, and the jet flow deflection nozzle 1 is respectively Installed at the position of.

  The fluid passages 4a and 5a of the fluid passage portions 4 and 5 of the nozzle body 2 are connected to a fluid supply means 15 capable of adjusting a fluid supply amount by a hose or the like, as schematically shown in FIG. The fluid supply means 15 includes a pump 16 and a fluid control valve 17.

  The fluid control valve 17 has two outflow passages 18b and 18c at symmetrical positions in the circumferential direction of the cylinder portion 18a, as schematically shown in FIG. 5 (the specific configuration will be described later). A valve housing 18 having an inflow passage 18d from the pump 16 at the lower end in the axial direction (the back side in FIG. 5) and a cylinder portion 18a of the valve housing 18 are rotatably fitted. A valve body 19 having an outlet hole 19a that can be matched across the outlets 18b and 18c, and an inlet hole 19b that matches the inflow path 18d at the lower end in the axial direction (the back side of the drawing in FIG. 5); An electric motor 20 (see FIG. 4) that continuously rotates the valve body 19 is provided.

  Then, the valve body 19 is continuously rotated around one direction by the electric motor 20, the outlet hole 19a is completely aligned with the outflow path 18b, and the outflow path 18c is completely blocked by the valve body 19 (a). At this point, the amount of fluid supplied to the fluid passage 4a connected to the outflow passage 18b is 100%, and the amount of fluid supply to the fluid passage 5a connected to the outflow passage 18c is 0%.

  Similarly, when the outlet hole 19a completely coincides with the outflow path 18c and the outflow path 18b is completely closed by the valve body 19, the amount of fluid supplied to the fluid path 5a is 100%, The amount of fluid supplied to the passage 4a is 0%.

  Further, at the time of FIG. 5C where the outlet holes 19a coincide with each other across the outflow passages 18b and 18c (overlap), the fluid supply amount to the fluid passage 4a is 50% and the fluid supply amount to the fluid passage 5a is 50%. It becomes.

  That is, referring to FIG. 6, if the fluid supply amount of the fluid passage 4a is adjusted to 100% and the fluid supply amount of the fluid passage 5a is adjusted to 0% by the rotation of the valve body 19, the injection flow is generated only from the injection port 4b. If the fluid supply amount of the fluid passage 5a is adjusted to 100% and the fluid supply amount of the fluid passage 4a is adjusted to 0%, the injection flow is injected obliquely upward only from the injection port 5b. Further, if the fluid supply amount of the fluid passages 4a and 5a is adjusted by 50%, the injection flow is injected obliquely downward and obliquely upward from the injection ports 4b and 5b, and collides at the intersection m. The jet f is deflected in a straight direction from the oblique direction.

  Therefore, if the fluid supply amount of the fluid passages 4a and 5a is adjusted to vary between 90% and 10%, 80% and 20%, 70% and 30%, 60% and 40%, 50% and 50%, In the collision at the intersection m, the jet flow in the diagonally downward direction is gradually deflected in a straight direction and jetted b → f, and the fluid supply amounts of the fluid passages 4a and 5a are subsequently 40%, 60%, and 30%. And 70%, 20%, 80%, 10%, and 90%, the straight jet flow is gradually deflected obliquely upward by the collision at the intersection m, and the injection g → j Will come to be.

  If the jet deflection nozzle 1 is configured as described above, the jet flow from the jet deflection nozzle 1 can be swung upward from below only by adjusting the fluid supply amount by the fluid control valve 17 of the fluid supply means 15. Therefore, it is possible to obtain a feeling of sideburn by massage by swinging (deflecting) the jet flow from below to above the back of the bather N. In addition, it is also possible to swing the jet flow from the jet flow deflection nozzle 1 downward from above by the reverse rotation of the electric motor 20. It is also possible to alternately repeat the swing from the bottom to the top and then the swing from the top to the bottom.

  Further, since the jet flow from the jet flow deflection nozzle 1 can be swung (deflected) simply by adjusting the fluid supply amount from the fluid supply means 15, when the jet nozzle is swung by an electric drive mechanism, Since the necessary measures for water tightness and rust prevention are not necessary, the jet deflection nozzle 1 and the fluid supply means 15 are simple and inexpensive, and the jet deflection nozzle 1 itself does not swing (deflect), so Since there is no possibility that it will be difficult to swing even if it adheres, etc., it becomes maintenance-free.

  Further, air r is supplied from the air supply pipe 6 to the injection opening 3, that is, the guide ports 12 a and 12 b of the nozzle body 2, and the air r is bubbled into the jet flow from the spray ports 4 b and 5 b. Since it is caught and injected, the acupressure feeling by massage can be improved more.

  Further, if the electric motor 20 is stopped in the injection direction according to the physique and preference of the bather N and the fluid supply amount in the fluid control valve 17 is fixed, the injection can be performed in the spot direction.

  Further, since each of the injection ports 4b and 5b is disposed at a symmetrical position with respect to the center C of the injection opening 3, the fluid supply amount can be easily adjusted.

  Further, since the jetting opening 3 has the shape of the slit 12e at the slit forming portion 12d of the jetting opening member 12, the jetting flow can be narrowed down and focused in the width direction of the slit 12e, so that the feeling of sprouting by massage is further improved. be able to.

  Furthermore, if the amount of fluid supply from the pump 16 of the fluid supply means 15 is adjusted, the strength of the jet flow from the jet ports 4b and 5b can be adjusted.

  As shown in FIG. 8, the injection opening 4 b ′ is further shifted to the injection opening 3 of the nozzle body 2 of the injection flow deflection nozzle 1 in the left-right direction shifted 90 degrees with respect to the vertical injection openings 4 b, 5 b of the bathtub 25. , 5 b ′, and a fluid control valve 17 ′, an electric motor 20 ′, etc. are separately provided for the injection ports 4 b ′ and 5 b ′, and the injection flow is swung upward from below by the injection ports 4 b and 5 b. (It is also possible to swing from the upper side to the lower side), and then the jet flow can be swung from the left to the right at the jet ports 4b 'and 5b' (swing from the right to the left is also possible). The massage effect can be further improved. In addition, the number of injection ports 4b and 5b is not limited to two or four, but may be three or five or more.

  In the embodiment, as shown in FIG. 7, the jet flow deflection nozzle 1 is attached to the G position facing the back of the bather N in the bathtub 25, but the jet is sprayed to the H position facing the sole. A flow deflection nozzle 1 can also be mounted. Alternatively, the jet deflection nozzle 1 can be attached at the I position facing the calf or the J position facing the thigh.

  Further, a fixed injection nozzle 24 that is not deflected is attached to a position K above the G position facing the back, and the injection flow deflecting nozzle 1 swings the injection flow from below to above the back of the bather N ( The massaging effect can be further improved if the jet stream is sprayed in a spot manner from the fixed spray nozzle 24 in accordance with the upper end of the swing. As with the jet flow deflection nozzle 1, the fixed jet nozzles 24 are respectively attached to two positions on the back symmetrically.
