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

  The hot water discharge device 1 of the first embodiment of the present invention is provided above a water receiving portion (not shown) such as a sink of a kitchen counter or a bowl of a washstand, for example.

  As shown in FIG. 2, the hot water discharge device 1 includes a first flow path 2 connected to an external hot water supply source (not shown) and a second flow path connected to an external water supply source (not shown). 3 and an outer shell portion 11 that forms an outer shell on the downstream side of the first flow path 2 and the second flow path 3. The outer shell portion 11 includes, for example, a base portion 13 provided on the upper surface of the edge portion of the water receiving portion and a spout 14 provided on the upper portion of the base portion 13.

  The base portion 13 is fixed to the upper surface of the edge portion of the water receiving portion. In other words, the edge of the water receiving part is a mounting base 9 to which the base part 13 is attached. The spout 14 is formed in a downward U-shaped cylindrical shape. One end (first end) of the U-shape of the spout 14 is connected to the upper portion of the base portion 13. And the spout 14 is arrange | positioned so that the remaining one end (2nd end) of U character may face the said water receiving part.

  Further, the spout 14 includes a discharge unit 12 and an operation unit 15 at the second end. The discharge unit 12 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 hot water discharge device 1 is configured to discharge hot water and water from the discharge portion 12. 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 12.

  The operation unit 15 is provided on the outer peripheral side of the discharge unit 12. The hot water discharge device 1 is configured to alternately switch between a state in which only the water is discharged from the discharge unit 12 and a state in which both hot water and water are discharged from the discharge unit 12 when the operation unit 15 is operated by the user. Composed. Hereinafter, unless otherwise specified, the cross-sectional shape is a surface cut perpendicular to the flowing direction of hot water or water (flow direction).

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

  As shown in FIGS. 1 and 3, the first flow path 2 has a first portion 24 on the downstream side thereof. The first portion 24 is formed in a cylindrical shape, for example. The first portion 24 is disposed so as to protrude upward from the mounting base 9. For this reason, the first portion 24 is covered with the outer shell portion 11. The first portion 24 is provided with an on-off valve (first valve 22). The first valve 22 is configured to open and close according to the operation of the operation unit 15. For this reason, in the first flow path 2, the water flow and the water stop are switched according to the opening and closing of the first valve 22. Hereinafter, the upstream side of the first flow path 2 of the first flow path 2 (the position disposed below the mounting base 9) is referred to as a third position 25 (details will be described later).

  Moreover, the 1st site | part 24 is provided with the baffle plate (not shown), for example in the downstream end (1st discharge port 21). For this reason, the 1st discharge port 21 is comprised so that water may be discharged in the shape of a circular section (columnar shape). The first discharge port 21 is not limited to the one provided with the rectifying plate as long as it can discharge linearly.

  The upstream side of the second flow path 3 is connected to the water supply source, and this water supply source is, for example, a water pipe. For this reason, the 2nd flow path 3 becomes the structure (water supply path) which discharges the water from the said water pipe from the downstream end (2nd discharge port 31).

  The 2nd flow path 3 has the 2nd site | part 34 in the downstream, as shown in FIG.1 and FIG.3. The second portion 34 is formed in a cylindrical shape, for example. The second portion 34 is disposed so as to protrude upward from the mounting base 9. For this reason, the second portion 34 is covered with the outer shell portion 11. The second portion 34 is provided with an on-off valve (second valve 32). The second valve 32 is configured to open and close according to the operation of the operation unit 15. For this reason, in the 2nd flow path 3, according to opening and closing of the 2nd valve 32, water flow and water stop are switched.

  Further, the downstream end portion (second end portion 33) of the second portion 34 has a flow path diameter that is smaller than the flow passage diameter of the downstream end portion (first end portion 23) of the first portion 24. It is large. The second end 33 is arranged so that the first end 23 is substantially concentric on the inner peripheral side thereof. In other words, the second end portion 33 is disposed so as to cover the outer periphery of the first end portion 23 with the first end portion 23 as the center.

  For this reason, the second discharge port 31 is formed in an annular cross section on the outer peripheral side of the first discharge port 21, and a portion (wall) on the inner peripheral side of this ring is formed by the first end 23. In other words, the second flow path 3 has the second discharge port 31 in an annular shape surrounding the outer peripheral side of the first discharge port 21. For this reason, the 2nd flow path 3 becomes a structure which discharges water from the 2nd discharge port 31 to the cyclic | annular form (cylinder shape) of circular cross section. Thereby, the discharge part 12 discharges so that linear hot water may be covered with cylindrical water, when discharging both hot water and water. The wall on the inner peripheral side of the ring of the second discharge port 31 (second end 33) is not limited to the one formed by the first portion 24.

  The second discharge port 31 is provided with a processing unit 4 for atomizing water. The process part 4 is comprised with a watering board, for example. The water spray plate includes a plurality of hole channels 41 and is configured to discharge water from each hole channel 41. As shown in FIG. 4, each hole channel 41 is classified into an upstream third channel 42 and a downstream fourth channel 43.

  The cross-sectional shape of the third channel 42 is substantially uniform in the direction of water flow. The fourth channel 43 is connected to the downstream end of the third channel 42. The fourth channel 43 is an enlarged portion that increases as the channel cross-sectional area goes downstream.

  For this reason, when the water in the second flow path 3 flows into the third flow path 42, the flow rate increases due to an increase in pressure or the like. Then, the water with the increased flow velocity (see W1 in FIG. 4) flows into the fourth flow path 43, the pressure decreases, and the interface is waved and atomized. It is discharged to the outside from the downstream end. In other words, the 2nd flow path 3 becomes a structure which atomizes water by the fluid shear accompanying the pressure fluctuation in the process part 4, and discharges it, for example in a shower shape.

  Thus, the hot water discharge device 1 includes the first flow path 2 and the second flow path 3 independently. For this reason, the hot water discharge device 1 is different from a mixing faucet or the like that mixes hot water and water in the middle of the flow path, and discharges hot water from the first discharge port 21 and discharges water from the second discharge port 31. Are configured to be performed independently. In other words, the discharge unit 12 includes the first discharge port 21 and the second discharge port 31 independently.

  And the hot-water discharge apparatus 1 is provided with the 2nd discharge port 31 so that the outer peripheral side of the 1st discharge port 21 may be enclosed. For this reason, when the hot water discharge device 1 discharges both hot water and water toward the object 8, for example, as shown in FIG. 1, when the central hot water touches the contact surface of the object 8, the contact surface It is easy to flow so that it may spread to the outer peripheral side along. And when the water which flows on the outer peripheral side of hot water touches a contact surface, the hot water discharge apparatus 1 is easy to flow so that it may spread to an outer peripheral side along a contact surface, mixing with the hot water which spreads to the said outer peripheral side.

  Thereby, the object 8 produces in the contact surface the part which only hot water touches, and the part which hot water and water mix and are easy to touch (part on the outer peripheral side of the part which only the hot water touches). When the object 8 is a human hand or the like, the hot water discharge device 1 makes it easy to generate a temperature sensation due to hot water at a portion where only the hot water is easily touched, and the hot water and water are mixed at the outer peripheral portion. Therefore, it is possible to make it difficult to cause the cold sensation of water.

  Further, the hot water discharge device 1 is configured such that the processing unit 4 is provided in the second discharge port 31 and discharges atomized water from the second discharge port 31. For this reason, the hot water discharge device 1 can make the contact area (surface area) with respect to the outside air (air) of water larger (wider) than the case where water is discharged in a continuous linear shape. Can easily absorb the heat. In other words, the hot water discharge device 1 can easily make the discharged water touch the outside air, and can easily increase the temperature of the water discharged from the second discharge port 31 by the heat of the outside air. Accordingly, the hot water discharge device 1 can bring the temperature of the water (water temperature) closer to the temperature of the outside air, and can make it difficult for the object 8 to be cooled by water.

  And the hot-water discharge apparatus 1 becomes a structure which discharges hot water from the 1st discharge port 21 in a single linear form. For this reason, compared with the water from the 2nd discharge outlet 31, the hot water discharge apparatus 1 can make the contact area with respect to external air small (narrow), and can suppress the thermal diffusion to the external air of hot water. Thereby, the hot water discharge device 1 can make the hot water sense of the object 8 easily.

  Further, the hot water discharge device 1 is provided with a second discharge port 31 in an annular cross section surrounding the outer peripheral side of the first discharge port 21. For this reason, the hot water discharge device 1 is configured so that the outer peripheral side of the hot water from the first discharge port 21 (the outer peripheral side with the discharge direction as an axis) is covered with the water from the second discharge port 31. Can be discharged. Accordingly, the hot water discharge device 1 can easily absorb this heat with the water on the outer peripheral side when, for example, part of the heat of the hot water is diffused, and the loss of the thermal energy of the hot water to the outside air can be reduced. It can be easily reduced.

  By the way, when the hot water discharge device 1 stops discharging hot water, the hot water remains in the first flow path 2 until hot water is discharged next time. When the hot water discharge device 1 discharges hot water again after hot water discharge, the hot water remaining in the first flow path 2 for a predetermined period from the start of the hot water supply source to the first discharge port 21. Is discharged from the first discharge port 21. Furthermore, the temperature of the remaining hot water decreases with time.

  For this reason, the hot-water discharge apparatus 1 has the heating part 71 which heats the hot water of the 1st flow path 2, as shown in FIG.2 and FIG.3. Specifically, in the first flow path 2, a bypass path is provided in the third portion 25. For this reason, the 3rd site | part 25 is comprised by the 5th flow path 5 and the bypass path (6th flow path 6).

  The fifth channel 5 has an upstream end connected to the hot water supply source. The fifth channel 5 has a downstream end connected to the first part 24. The sixth channel 6 has an upstream end connected to the upstream side of the fifth channel 5. The sixth channel 6 has a downstream end connected to the downstream side of the fifth channel 5. For this reason, the 3rd site | part 25 becomes a structure which mixes the hot water of the 5th flow path 5, and the hot water of the 6th flow path 6, and flows in into the 1st site | part 24. FIG.

  The sixth flow path 6 is provided with a heater 7 that can heat the hot water (hot water in the sixth flow path 6). The heater 7 is configured to heat hot water remaining in the sixth flow path 6 and hot water flowing into the sixth flow path 6 from the hot water supply source. And since the 6th flow path 6 makes this heated hot water join the hot water of the 5th flow path 5, the heating by the heater 7 is heating of some hot water in the 1st flow path 2. In other words, the heater 7 is configured to perform auxiliary heating as compared with the heating at the hot water supply source.

  The heater 7 is disposed below the mounting base 9. For this reason, the heater 7 can be arrange | positioned in the position which is concealed by the said water receiving part and is not conspicuous in an external appearance. Moreover, the heater 7 is provided with the heating part 71, the detection part 73, and the control part 72, as shown in FIG.

  The heating unit 71 is provided on the outer periphery of the sixth flow path 6. Specifically, the heating unit 71 is disposed in contact with the sixth flow path 6. The heating unit 71 is provided so as to cover the entire circumference of the sixth flow path 6 (the whole circumferential direction with the flowing direction of hot water as an axis). Moreover, the heating part 71 is comprised so that the hot water inside (hot water of the 6th flow path 6) may be heated, for example, is formed with the electric heating member which generate | occur | produces with electric power.

  The heater 7 includes, as the detection unit 73, a first detection unit 74 that detects the temperature (hot water temperature) of hot water upstream from the heating unit 71 of the first flow path 2, and a heating unit 71 of the first flow path 2. A second detector 75 for detecting the hot water temperature on the downstream side and a third detector 76 for detecting the flow rate of the hot water in the first flow path 2 are provided.

  The 1st detection part 74 is provided in the upstream from the heating part 71 of the 6th flow path 6, for example, and becomes a structure which detects the hot water temperature in this upstream position. The 2nd detection part 75 is provided in the downstream from the heating part 71 of the 6th flow path 6, for example, and becomes the structure which detects the hot water temperature in this downstream position. For this reason, the 1st detection part 74 and the 2nd detection part 75 are temperature measuring parts which detect the hot water temperature of the 1st flow path 2 (6th flow path 6).

  The third detector 76 is provided on the downstream side of the second detector 75. The third detection unit 76 is a detection unit (discharge detection unit) for detecting whether or not hot water is discharged from the first discharge port 21 (discharge and stoppage thereof).

  For this reason, the heater 7 is configured to include, as the detection unit 73, two upstream and downstream temperature detection units based on the position of the heating unit 71 and a discharge detection unit for the first flow path 2. ing. Moreover, each detection part 73 is comprised so that the detection result may be output to the control part 72, for example, and the control part 72 acquires each detection result by this.

  As shown in FIG. 6, the control unit 72 is configured to perform switching control of heating of the heating unit 71 and its stop according to the detection result. And the control part 72 becomes a structure controlled to perform the heating in the heating part 71, when there exists discharge of hot water (when it is the state which is performing the discharge operation of hot water).

  For example, when the detection result of the third detection unit 76 is less than a predetermined value, the control unit 72 determines that hot water is not discharged (no hot water discharging operation is performed), and when the detection result is equal to or greater than the predetermined value, It is determined that there is discharge. And the control part 72 is less than predetermined | prescribed lower limit (refer the dotted line L2 in FIG. 6) by the detection result (refer the continuous line L1 in FIG. 6) of the 1st detection part 74 in the state determined that there exists discharge of hot water. In this case, the heating unit 71 is controlled to operate (heat generation). Further, the control unit 72 is configured to control the heating unit 71 to stop when the detection result of the first detection unit 74 is equal to or greater than the lower limit value in a state where it is determined that hot water is discharged.

  Here, in the lower limit value, the temperature corresponding to the detection result is, for example, a temperature corresponding to a state in which a predetermined time has passed (predetermined amount) after arrival of hot water heated by the hot water supply source, or hot water discharge start It is a temperature obtained by adding a predetermined value to the temperature of the hour.

  In addition, when the heating unit 71 is in operation, the control unit 72 detects that the detection result of the second detection unit 75 (see the solid line L3 in FIG. 6) is equal to or higher than the upper limit (see the dotted line L4 in FIG. 6). It is the structure which controls so that 71 may be stopped. The control unit 72 is configured to control the heating unit 71 to operate (heat generation) when the detection result of the second detection unit 75 is less than the upper limit value during the operation of the heating unit 71.

  Furthermore, the control of the heating unit 71 according to the upper limit value is a control that is continuously performed until the detection result of the first detection unit 74 becomes equal to or higher than the lower limit value. Further, the upper limit value is set such that the hot water temperature corresponding to the detection result that is the value is higher than the hot water temperature corresponding to the detection result that is the lower limit value.

  In the upper limit value, the temperature corresponding to the detection result is likely to cause contradictory cold sensation, for example, from 25 ° C. exceeding the peak of cold sensation (which makes it difficult to cause cold sensation as the temperature rises). It is preferable that the temperature is set in the range of 45 ° C. on the near side.

  Furthermore, the control unit 72 stops the heating unit 71 when it is determined from the detection result of the third detection unit 76 that hot water is not discharged, for example, by stopping hot water discharge during the operation of the heating unit 71. It is the structure to control.

  That is, the control unit 72 is configured to control the heating of the heating unit 71 so that the hot water in the first flow path 2 is in a predetermined temperature condition. In other words, the hot water discharge device 1 adjusts the hot water temperature of the hot water supply source to be a predetermined condition by performing feedback control using the detection result of the temperature detection unit on the heating unit 71 by the control unit 72. can do.

  As described above, the hot water discharge device 1 is provided with the heating unit 71 in the sixth flow path 6 (the first flow path 2), thereby heating the hot water whose temperature has been decreased and increasing the temperature to the first discharge port. 21 can be discharged. Thereby, when the hot water discharge apparatus 1 discharges the hot water which remained from the 1st discharge port 21, it can make it hard to produce the cold sensation by the hot water whose temperature fell on the target object 8.

  And the hot-water discharge apparatus 1 was provided with the detection part 73 and the control part 72 comprised so that feedback control of the heating part 71 might be performed based on the detection result of the detection part 73, hot water temperature, the presence or absence of discharge, etc. The heating of the heating unit 71 and its stop can be switched according to the above. For this reason, the hot-water discharge apparatus 1 can suppress the power consumption by the heating part 71 by stopping the heating part 71, for example, when the hot water is likely to cause a temperature sensation or when the hot water is not discharged. .

  As a result, the hot water discharge device 1 can reduce the power consumption by the heating unit 71 and can easily cause the hot water sense from the first discharge port 21. Furthermore, the hot water discharge device 1 sets the temperature condition of the hot water heated by the heating unit 71 (feedback control by temperature) within the above-described temperature range, so that hot water at a temperature at which the object 8 is most likely to generate a temperature sensation is obtained. It can be discharged.

  In addition, the first flow path 2 is provided with a heat insulating member (not shown) in a portion (including the fifth flow path 5) downstream of the heating portion 71 of the first portion 24 and the third portion 25. The heat insulating member is configured to insulate the downstream portion from an external environment (an outer peripheral environment) of the portion. In other words, the heat insulating member covers the downstream portion, thereby forming a heat insulating structure in this portion. In addition, the heat insulating member provided in the first portion 24 among the downstream portions is covered with the outer shell portion 11.

  Thus, the hot water discharge device 1 has a heat insulating structure at a site downstream of the heating unit 71 of the first flow path 2. For this reason, the 1st flow path 2 can suppress the temperature fall by the external environment of the site | part of the said downstream. Thereby, the hot water discharge device 1 can reduce the temperature drop of the hot water heated by the heating unit 71 and the hot water from the hot water supply source in the downstream portion.

  And the hot-water discharge apparatus 1 can suppress the temperature fall accompanying the time passage of the hot water which remained in the downstream site | part by the said heat insulation structure. For this reason, the hot-water discharge apparatus 1 can make it difficult to produce the cold sensation due to the hot water whose temperature has decreased in the object 8 when hot water remaining in the downstream portion is discharged from the first discharge port 21. .

  Moreover, you may provide the hot-water discharge apparatus 1 in a bathroom, and in this case, a water receiving part becomes the upper surface of a washing place, a bathtub, etc., for example. Further, the hot water discharge device 1 branches the flow path connecting the hot water supply source and the first flow path 2, and mixes the branched hot water and water from the water supply source with the second flow path 3. It may be provided on the upstream side. In other words, the 2nd flow path 3 may discharge the water (mixed water) which mixed hot water and water from the 2nd water discharge port separately from the hot water of the 1st discharge port 21, etc. Moreover, the 1st flow path 2 may provide the heating part 71 in the 5th flow path 5, etc., without branching the 3rd site | part 25.

  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.
