  However, in the hand-washing apparatus, when the heated wind and hand-washing water are discharged, the blower fan is operated, so that it is difficult to reduce power consumption.

  This invention is made | formed in view of the said situation, Comprising: It makes it a subject to provide the water discharging apparatus which eased the cold sensation to the user by this water at the time of water discharge, and suppressed power consumption.

  In order to solve the above problems, the present invention includes a first flow path for discharging water and a second flow path for discharging hot air, and the water discharge port of the first flow path and the discharge of the second flow path.

  According to the present invention, the warm air in the second flow path can be sent out along the water discharge direction (water flow direction) by the suction pressure. For this reason, the present invention can discharge hot air at the time of water discharge without sending out hot air in the second flow path by a fan or the like, and can reduce power consumption by the fan or the like. And since this invention sends out warm air from a 2nd flow path with the said suction pressure, compared with the case where warm air is sent out with a fan etc., the water from a spout makes it difficult to receive the influence of the flow of warm air.

  Hereinafter, the present invention will be described with reference to the accompanying drawings.

  The water discharging apparatus 1 of 1st embodiment of this invention is provided above the water-receiving parts 7, such as a sink of a kitchen counter, a bowl of a washstand, etc., as shown in FIG.

  The water discharge device 1 includes a first flow path 2 that discharges water 29 supplied from an external water supply source (not shown), a second flow path 3 that takes in outside air and discharges it as hot air 39, and a first flow And an outer shell portion 11 that forms an outer shell on the downstream side of the path 2 and the second flow path 3. The outer shell portion 11 includes, for example, a base portion 12 provided at an edge portion of the water receiving portion 7 and a spout 13 provided at an upper portion of the base portion 12.

  The base 12 is fixed to the upper surface of the edge of the water receiver 7. In other words, the edge of the water receiving portion 7 is a mounting base 71 to which the base portion 12 is attached. The spout 13 is formed in a downward U-shaped cylindrical shape. The spout 13 has a U-shaped one end (first end) connected to the upper portion of the base 12. The spout 13 is arranged so that the remaining one end (second end) of the U-shape faces the water receiving portion 7.

  Further, the spout 13 includes a discharge unit 14 at the second end. The discharge unit 14 is provided with a downstream end of the first flow path 2 and a downstream end of the second flow path 3. For this reason, the water discharge device 1 is configured to discharge water 29 and warm air 39 from the discharge unit 14. In other words, the downstream end of the first flow path 2 and the downstream end of the second flow path 3 are open to the discharge unit 14.

  Furthermore, the water discharge device 1 includes an operation unit (not shown). The water discharge device 1 is configured to discharge both the water 29 and the warm air 39 from the discharge unit 14 in accordance with the operation of the operation unit. Hereinafter, unless otherwise specified, the cross-sectional shape is a surface cut perpendicular to the direction in which the water 29 or the warm air 39 flows (flow direction).

  The upstream side of the first flow path 2 is connected to the water supply source, and this water supply source is, for example, a water pipe. For this reason, the 1st flow path 2 becomes the structure (water supply path) which discharges the water 29 from the downstream end (water discharge port 21).

  As shown in FIG. 1, the first flow path 2 has a first portion 22 on the downstream side thereof. The first portion 22 is covered with the outer shell portion 11. For example, the first portion 22 is formed in a cylindrical shape. As for the 1st site | part 22, the baffle plate (not shown) is provided in the edge part (water outlet 21). For this reason, the 1st flow path 2 becomes the structure which discharges the water 29 from the spout 21 along the flow direction in the cross-section circular shape (columnar shape). The spout 21 is not limited to the one provided with the rectifying plate as long as it can be discharged linearly.

  Further, the downstream end portion (first end portion 23) of the first portion 22 has a tapered shape in which the flow path diameter becomes narrower toward the downstream side. In other words, the first end portion 23 includes a first reduced diameter portion 24 whose flow path diameter becomes narrower toward the downstream side, and a first small diameter portion 25 connected to the downstream end of the first reduced diameter portion 24. The cross section of the first small diameter portion 25 is substantially uniform in the flow direction of the water 29. The diameter of the first small diameter portion 25 is substantially the same as the diameter of the downstream end of the first reduced diameter portion 24. As for the 1st small diameter part 25, the downstream end serves as the spout 21.

  For this reason, the spout 21 has a configuration in which the flow rate of the water 29 to be discharged is faster than the flow rate of the upstream portion of the first reduced diameter portion 24 (the tapered portion). In other words, the water outlet 21 is configured to accelerate and discharge the water 29.

  The second flow path 3 has an outside air (air) intake 31 on the upstream side thereof. The intake 31 is arrange | positioned below the edge part (mounting base 71) of the water receiving part 7, for example. The second flow path 3 is provided with a heating unit 33 on the downstream side of the intake port 31. The heating unit 33 is arranged below the mounting base 71. For this reason, the intake port 31 and the heating part 33 can be arrange | positioned in the position which is concealed by the water receiving part 7, and is not conspicuous in an external appearance.

  The heating unit 33 heats the air taken into the second flow path 3 from the intake port 31. For this reason, the 2nd flow path 3 becomes the structure (air supply path) which discharges the warm air 39 from the downstream end (discharge port 32). In addition, the heating unit 33 switches between heating of the air and stopping thereof according to the operation of the operation unit, for example.

  The second flow path 3 has a second portion 34 on the downstream side thereof. The second portion 34 is formed in a cylindrical shape, for example. The second portion 34 is covered with the outer shell portion 11. Further, the downstream end portion (second end portion 35) of the second portion 34 has a larger flow path diameter than the flow path diameter of the first end portion 23. And the 2nd end part 35 is arrange | positioned by the 1st end part 23 concentrically on the inner peripheral side. In other words, the second end portion 35 is disposed so as to cover the outer periphery of the first end portion 23 with the first end portion 23 as the center. The discharge port 32 is located on the downstream side of the water discharge port 21.

  For this reason, the outer periphery of the water discharge port 21 is covered with the second end portion 35. And the 2nd end part 35 (the flow path) becomes the cross-sectional annular | circular shape surrounding the outer peripheral side of the water discharge port 21 in the outer periphery of the water discharge port 21, The site | part (wall) of the inner peripheral side of this ring is the 1st. It consists of an end 23. In other words, the second flow path 3 has the second end portion 35 in an annular shape surrounding the outer peripheral side of the water discharge port 21. The wall on the inner peripheral side of the ring of the second end portion 35 is not limited to the one formed by the first portion 22.

  Furthermore, the second end portion 35 has a tapered shape in which the flow path diameter becomes narrower toward the downstream side. The second end portion 35 has a larger diameter at the tip (discharge port 32) than the diameter of the water discharge port 21. In other words, the second end portion 35 includes a second reduced diameter portion 36 whose flow path diameter becomes narrower toward the downstream side, and a second small diameter portion 37 connected to the downstream end of the second reduced diameter portion 36.

  The diameter of the downstream end of the second reduced diameter portion 36 is larger than the diameter of the first small diameter portion 25. The second small diameter portion 37 has a substantially uniform cross-sectional shape in the flow direction of the water 29. The diameter of the second small diameter portion 37 is substantially the same as the diameter of the downstream end of the second reduced diameter portion 36. The second small diameter portion 37 has a discharge port 32 at the downstream end thereof.

  Thus, the water discharging apparatus 1 arranges the first end portion 23 on the inner peripheral side of the second end portion 35 so that the hot air 39 is discharged from the discharge port 32 into an annular shape (cylindrical shape). Composed.

  For this reason, the water discharge device 1 can discharge both the water 29 and the hot air 39 so that the linear water 29 is covered with the tubular hot air 39 from the discharge unit 14, and can be used as an object such as a user's hand. It is possible to easily increase the area where the hot air 39 hits the object 8. As a result, the water discharge device 1 can make the user feel a thermal feeling of the hot air 39 (temperature sensation by the hot air 39) more easily than the case where the hot air 39 is mixed inside the water 29 or mixed. It is possible to easily relieve the user's cold sensation due to water discharge. And since the water discharging apparatus 1 heats air with a small specific heat compared with the water 29, it can make it easy to suppress power consumption compared with the case where the water 29 is heated.

  Furthermore, since the discharge port 32 is located downstream from the water discharge port 21, the discharge port 32 is configured to join and discharge the water 29 so as to be wrapped by the warm air 39. For this reason, in the second end portion 35, a portion located on the outer periphery of the water discharge port 21 is a merging port for merging the warm air 39 with the water 29.

  Moreover, the water discharging apparatus 1 can make suction pressure generate | occur | produce on the outer peripheral side of the water discharge port 21, for example, when water discharges by having made the 1st end part 23 into the tapered shape. And the water discharging apparatus 1 has provided the discharge port 32 close to the water discharge port 21 so that the air in the 2nd flow path 3 may be sent out with the said suction pressure.

  For this reason, the water discharging apparatus 1 can send out the warm air 39 of the 2nd flow path 3 along the water discharging direction (flow direction of the water 29) with the said suction pressure. Accordingly, the water discharge device 1 can discharge the hot air 39 during water discharge without sending out the hot air 39 in the second flow path 3 with a fan or the like, and can reduce power consumption by the fan or the like. it can.

  Further, for example, since the water discharge device 1 sends out the warm air 39 from the second flow path 3 by the suction pressure, the water 29 from the water discharge port 21 is less than the warm air 39 compared to the case where the warm air 39 is sent out by a fan or the like. It can be made less affected by the flow.

  Further, the water discharge device 1 has the second end portion 35 tapered, so that the suction pressure per unit area applied to the second flow path 3 can be easily increased. It is possible to facilitate delivery with intake pressure.

  And the water discharging apparatus 1 made the 2nd end part 35 taper shape, and compared the flow velocity of the warm air 39 to discharge compared with the flow velocity upstream from the 2nd diameter-reduced part 36 (taper-shaped site | part), Can be fast. In other words, the second flow path 3 is configured to accelerate and discharge the hot air 39. For this reason, the water discharging apparatus 1 can make it easy to reach the object 8 by, for example, suppressing the diffusion of the hot air 39, and can make it easy to cause a warm sensation due to the hot air 39.

  Next, a second embodiment will be described. In addition, the same code | symbol is attached | subjected to the structure which overlaps with above-mentioned 1st embodiment, the description which overlaps is abbreviate | omitted, and the characteristic of this example (2nd embodiment) is demonstrated.

  The water discharge device 1 of this example has a water discharge mode for discharging both water 29 and hot air 39 and a hot air mode for discharging only the hot air 39. And the water discharging apparatus 1 is provided with the said operation part (1st operation part) for the water discharge in water discharge mode, and the 2nd operation part (it mentions later for details) for the warm air 39 discharge in a warm air mode.

  As shown in FIG. 3, the air flow part 4 is provided in the 2nd flow path 3. As shown in FIG. The air blowing unit 4 is disposed below the mounting base 71. For this reason, the ventilation part 4 can be arrange | positioned in the position which is concealed by the water receiving part 7, and is not conspicuous in an external appearance. And the ventilation part 4 is arrange | positioned upstream from the heating part 33 of the 2nd flow path 3. As shown in FIG. The air blowing unit 4 is configured to send air to the downstream side of the second flow path 3 by driving thereof. The blower unit 4 is, for example, a blower fan.

  Further, the air blowing unit 4 is configured to operate only in the warm air mode. In other words, the air blower 4 is configured to operate in the warm air mode and not operate in the water discharge mode. For this reason, the water discharge device 1 has a configuration in which, in the water discharge mode, the warm air 39 is sent out from the discharge port 32 with the suction pressure generated by the water discharge, and the power consumption due to the operation of the blower unit 4 is reduced.

  The second operation unit is provided in the spout 13. The second operation unit includes, for example, a detection unit 5 that detects an object. As shown in FIGS. 4 and 5, the detection unit 5 is provided at a site on the side of the discharge unit 14.

  And the detection part 5 has the detection area | region E1 in the lateral outer side of the discharge part 14, as shown in FIG. As shown in FIG. 6, the detection unit 5 causes the output value P1 (detection output) of the detection result to be a predetermined value P2 when the object is positioned in the detection region E1. That is, the detection area E1 is a range in which the detection output becomes the predetermined value P2. In other words, the detection unit 5 is configured to detect the presence of an object when the output value P1 is the predetermined value P2.

  For this reason, the detection unit 5 is a so-called limited reflection type non-contact sensor. Specifically, the detection unit 5 is, for example, an infrared reflection type sensor that detects an object using infrared rays (light in a wavelength band in the infrared region), a so-called infrared sensor. The infrared sensor includes a light emitting unit 51 that emits infrared light, and a light receiving unit 52 that receives a part of the infrared light reflected by the object among the infrared light emitted from the light emitting unit 51. Furthermore, the object detected by the detection unit 5 is, for example, a user's hand.

  As shown in FIG. 6, the blower unit 4 operates when a detection output (output value P1) of a predetermined value P2 or more is input from the detection unit 5. In other words, the air blower 4 operates when an object is detected by the detector 5. And the ventilation part 4 stops the operation | movement, if a detection part 5 detects an object again, or when fixed time passes since ventilation start.

  As described above, the water discharge device 1 is configured to start the operation in the warm air mode when the detection unit 5 detects an object in the water discharge mode or the water discharge stop state. In other words, the water discharge device 1 starts heating the air by the heating unit 33 and sending out the air by the blower unit 4 when the detection unit 5 detects an object in the water discharge mode or the stopped state.

  For this reason, for example, the water discharge device 1 can dry the object 8 wet in the water discharge mode with the warm air 39 in the warm air mode, thereby improving convenience and the like. Furthermore, since the water discharge device 1 discharges the water 29 and the warm air 39 in the water discharge mode and the warm air 39 in the hot air mode from the same discharge unit 14, the user can perform washing (hand washing) in the water discharge mode and drying it. Can be performed by substantially the same operation. And the water discharging apparatus 1 can start the operation | movement in a warm air mode, for example, even if it does not operate with the hand wet with the water 29 of the water discharging mode by having used the detection part 5 as the non-contact sensor.

  Moreover, the 2nd flow path 3 can accelerate and discharge the warm air 39 by making the 2nd edge part 35 into the tapered shape. For this reason, the water discharging apparatus 1 can make it easy to accelerate the drying speed of the object 8 by the warm air 39 in the warm air mode. In other words, the water discharge device 1 can facilitate the drying of the object 8 in the warm air mode by accelerating from the second portion 34 and discharging the warm air 39.

  Further, the water discharge device 1 may be one that discharges hot water or hot water mixed with hot water from the first flow path 2. In this case, for example, in the modification shown in FIG. 7, a mixing unit 26 that mixes hot water and water is provided upstream of the first portion 22 of the first flow path 2. And the 1st flow path 2 has the 3rd site | part 27 in which water flows in into the mixing part 26 from the said water supply source, and the 4th site | part 28 into which hot water flows in from an external water heater (not shown). Connected.

  In other words, the first flow path 2 has the first part 22 on the downstream side of the mixing part 26, and has the third part 27 and the fourth part 28 on the upstream side of the mixing part 26. The water in the third part 27 and the hot water in the fourth part 28 flow into the first part 22 through the mixing unit 26. For this reason, in the water discharge device 1, water 29 (hot water) obtained by mixing hot water and water in the mixing unit 26 is discharged from the water discharge port 21. As a result, the water discharge device 1 can discharge water in a state where the water temperature is increased by hot water, compared with the case where only the water 29 from the water supply source is discharged, and the cooling sensation caused by the water 29 is alleviated. Can be made easier.

  Moreover, it is preferable that the water discharging apparatus 1 provides the filter 38 in the intake port 31, as shown in FIG. Moreover, you may provide the water discharging apparatus 1 in a bathroom etc., In this case, the water receiving part 7 becomes the upper surface (upper surface of a floor), a bathtub, etc., for example.

  The present invention is not limited to the above-described configuration, and can be implemented with appropriate modifications within a range not departing from the gist.
