Stop spraying mist-like hot water.

<Temperature adjustment operation example with hot water spray nozzle>
Next, the temperature adjustment operation by the hot water spray nozzle 1 having the above-described configuration will be described with reference to the drawings.

  When the operation switch 61 shown in FIG. 9 is operated to instruct the spray of mist-like hot water, the controller 63 opens the electromagnetic valve 54. When the electromagnetic valve 54 is opened, hot water is pumped from the water heater 53 shown in FIG. 8 to each hot water spray nozzle 1 of the hot water spray device 31 through the hot water pipe 33.

  The hot water spouting nozzle 1 is supplied with hot water into the water channel 17 of the rotator 9 constituting the ejection unit 3. The hot water supplied to the water channel 17 of the whirling device 9 is fed into the groove 15 through the through hole 18. In the swirler 9, the swirl portion 13 in which the groove 15 is formed is inserted into the insertion hole 20 of the main body 10, and a gap is almost formed between the outer peripheral surface of the swirl portion 13 and the inner peripheral surface of the insertion hole 20. Therefore, the hot water fed into the groove 15 passes through the spiral groove 14 and is jetted at high speed from the ejection nozzle 23 of the nozzle plate 11 while drawing a spiral.

  In addition, the hot water sprinkling nozzle 1 is connected to the air pipe 34 as shown in FIG. 6 at the air inlet 8 of the air chamber forming member 2, and the air pipe 34 is installed on the outer wall 56 of the building 51 as shown in FIG. Since it is connected to the intake grill 55, the air outside the bathroom 41, in this example, outside air, is taken into the air chamber 5 formed in the air chamber forming member 2.

  In the hot water spouting nozzle 1, a pressure drop occurs in the air mixing portion 27 a on the back surface side of the jet outlet 27 due to the high-speed jet from the jet nozzle 23 of the jet unit 3. And by the pressure fall in the air mixing part 27a, the air of the air chamber 5 is taken in from the air intake port 29, and mist-like hot water is injected from the outlet 27 in the shape of a conical spiral while entraining air in the air mixing part 27a. Is done.

  Now, compared with the temperature in the bathroom 41, the temperature of the outdoor where the intake grille 55 is installed or the bathroom is generally low. For this reason, the air outside the bathroom 41 is taken in by the hot water spouting nozzle 1, and the air is entrained and sprayed in the mist-like hot water, thereby comparing the temperature of the hot water supplied to the hot water spouting nozzle 1. The ejection temperature from the ejection nozzle 1 can be lowered.

  Then, by changing the opening area of the air intake port 29, the amount of air entrained in the mist-like hot water can be changed, and the ejection temperature from the hot water spray nozzle 1 can be adjusted.

  FIG. 10 is a configuration diagram showing a state of the hot water spray nozzle 1 during temperature adjustment. The temperature adjustment dial 4 of the hot water spray nozzle 1 can adjust the opening area of the air intake port 29 by turning the dial portion 24 to change the screwing amount of the inner cover 26 into the main body 10. Thereby, the amount of air taken in from the air inlet 29 can be adjusted.

  For example, when the temperature adjustment dial 4 is closed, as shown in FIG. 10A, the screwing amount of the inner cover 26 into the main body 10 increases, and the opening area of the air intake port 29 decreases. Thereby, the amount of air taken in by the air mixing unit 27a is reduced, and the temperature at which the hot water spray nozzle 1 ejects can be increased.

  On the other hand, when the temperature adjustment dial 4 is opened, as shown in FIG. 10B, the screwing amount of the inner cover 26 into the main body 10 decreases, and the opening area of the air intake port 29 increases. To do. Thereby, the air intake amount in the air mixing part 27a increases, and the jet temperature from the hot water spray nozzle 1 can be lowered.

  Therefore, if the bather feels hot, opening the temperature adjustment dial 4 increases the amount of air taken in, lowers the spray temperature of the mist-like hot water from the hot water spray nozzle 1, and increases the temperature of the bathroom 41. Can be lowered. If the bather feels cold, close the temperature adjustment dial 4 to reduce the amount of air taken in, increase the spray temperature of hot water from the hot water spray nozzle 1, and adjust the temperature of the bathroom 41. Can be raised.

  Thereby, even if the temperature of the hot water supplied to the hot water spray nozzle 1 is constant, the jet temperature from the hot water spray nozzle 1 can be adjusted. Therefore, mixing of water for adjusting the temperature of the hot water becomes unnecessary, and the ejection temperature can be adjusted without changing the ejection amount.

  Since the amount of air taken in is adjusted at the back surface of the jet outlet 27, the temperature is adjusted near the jet outlet 27, so that the temperature actually changes in response to the operation of the temperature adjustment dial 4. The delay time up to can be made substantially zero.

  Further, by adjusting the opening area of the air intake port 29 by screwing the temperature adjustment dial 4, the opening degree of the air intake port 29 can be gradually changed with respect to the operation of the temperature adjustment dial 4. A rapid change in temperature can be prevented while ensuring followability to the operation of the temperature adjustment dial 4.

  Here, in the case where a plurality of hot water spray nozzles 1 are provided, it is possible to individually adjust the ejection temperature by adjusting the opening of the temperature adjustment dial 4 of each hot water spray nozzle 1.

  Accordingly, in the bathroom 41 shown in FIG. 7, for example, if the hot water spray nozzles 1 are provided near the floor and near the center, respectively, the temperature near the floor is increased as necessary, and the height of the bather's head is increased. Individual temperature control that lowers the temperature in the vicinity can be easily performed.

  In the above example, the adjustment of the opening of the temperature adjustment dial 4 of the hot water spray nozzle 1 is performed manually, but it is also easy to perform automatically by using a driving means such as a motor. is there.

  Moreover, although the hot water sprinkling room is described as a bathroom, it may be another space such as a dedicated mist sauna room.
