  This type of bathroom mist device has a mist operation in which a spray head having a mist nozzle is arranged in the bathroom, hot water heated by heating means is supplied to the spray head, and hot water is ejected from the mist nozzle into the mist in the bathroom. Configured to do. In addition, a remote controller is provided so that the heating means is activated and hot water is supplied to the spray head by an instruction operation of mist operation to the remote controller.

  Further, in order to prevent the cold water mist from being ejected at the beginning of the mist operation, there is also known one in which the hot water is supplied to the spray head when the hot water is heated to a predetermined temperature by the heating means (for example, , See Patent Document 1).

By the way, some users may desire to preheat the bathroom with a hot water mist jet before bathing. In this case, since the remote control is generally placed in the bathroom, it is necessary for the user to enter the bathroom with clothes and operate the remote control. When squirts, clothes get wet. Even when the hot water is supplied to the spray head when the hot water is heated to a predetermined temperature as described above, the mist operation is repeated, and if the time does not stand up from the previous mist operation, It is also used for other purposes than driving, and when the heating means is preheated by operation in other purposes, the time from when the hot water temperature rises quickly and the remote control is operated until the mist is ejected There is a possibility that mist may be ejected before the user retreats from the bathroom by operating the remote control. In particular, when an operation for changing the setting related to the operating time of the mist operation or the temperature of hot water supplied to the spray head is performed on the remote controller, there is a high possibility that mist will be ejected during this operation. Therefore, it is unavoidable to operate the remote control while entering the bathroom with clothes on, and it is difficult to preheat the bathroom with a hot water mist jet before taking a bath.
Japanese Patent Laid-Open No. 2002-489 (0007, FIG. 1)

  In view of the above, the present invention provides a bathroom mist that allows a user who wants to preheat a bathroom with a jet of hot water mist before bathing to enter the bathroom and operate the remote control while wearing clothes. The problem is to provide a device.

In order to solve the above problems, the present invention provides a spray head having a mist nozzle in a bathroom, supplies hot water heated by heating means to the spray head, and ejects hot water from the mist nozzle into the bathroom in a mist form. A bathroom mist device configured to perform a mist operation that includes a remote controller that instructs the mist operation and that can change a setting related to at least one of an operation time of the mist operation and a temperature of hot water supplied to the spray head A delay timer that starts timing when a mist operation instruction operation is performed on the remote control , and the delay timer changes the setting for the remote control after the mist operation instruction operation until the delay timer times out operation is reset each time a Ru conducted is configured to start counting operation again, the delay timer is timed up Characterized by starting the hot water supply to the spray head when.

  According to the above configuration, regardless of the temperature of the hot water before the operation of the heating means, the supply of hot water to the spray head is delayed by a fixed time determined by the delay timer from the time when the mist operation instruction operation is performed on the remote controller. Will start. Therefore, by setting this fixed time to a time that can be evacuated outside the bathroom, even if the user enters the bathroom while wearing clothes and performs the mist operation instruction operation on the remote control, It is reliably prevented that mist is blown out before getting out of the bathroom and clothes get wet.

  In addition, when a setting change operation is performed on the remote controller, the delay timer is reset, so that the supply start time of the hot water to the spray head is further delayed. Therefore, mist is not ejected during the setting change operation, and the setting change operation can be performed calmly without panic. Thus, a user who wants to preheat the bathroom with a hot water mist before taking a bath can safely enter the bathroom with clothes and operate the remote control including the setting change operation. Will be better.

  With reference to FIG. 1, 1 is a bathroom, 2 is a bathtub, and a bathroom heating device 3 is disposed on the ceiling of the bathroom 1. The bathroom heating device 3 has a built-in heat radiator (not shown) connected to a heat source device 4 disposed outdoors or the like via a heating circulation path 5 including an outgoing pipe 5a and a return pipe 5b. The hot water heated by the heat source machine is circulated, and the air in the bathroom 1 is circulated and heated by a radiator to heat the bathroom 1. The heat source unit 4 is a composite heat source unit that also has a hot water supply function, and heats the water supplied from the water supply channel 6 to supply hot water to a hot water outlet terminal such as a currant or a shower head (not shown).

  Further, a spray head 7 is disposed on a wall surface 1 a at a suitable place such as a ceiling portion of the bathroom 1. And the hot water heated by the mist heating unit 8 is supplied to the spray head 7 through the mist hot water supply passage 9, and the hot water is jetted into the bathroom 1 in a mist shape so that the sauna effect can be obtained. .

  The mist heating unit 8 includes a plate-type liquid-liquid heat exchanger 10 as shown in FIG. The heating pipe 10a on the primary side of the liquid heat exchanger 10 is connected to the heat source unit 4 via a bypass circulation path 11 composed of an outgoing pipe 11a and a return pipe 11b in parallel with the heating circulation path 5. Hot water heated to a predetermined high temperature (for example, 80 ° C.) by the machine 10 is circulated to the heating pipe 10 a via the bypass circulation path 11. Further, a branch path 6a of the water supply path 6 connected to the heat source unit 4 and a hot water supply path 9 for mist are connected to the upstream side and the downstream side of the secondary heat absorption pipe 10b of the liquid heat exchanger 10, respectively. Then, the water flowing through the heat absorption pipe 10 b is heated by the heat of the high-temperature hot water flowing through the heating pipe 10 a and supplied to the spraying head 7 through the mist hot water supply passage 9.

  The bypass circulation path 11 is provided with a flow rate control valve 12 for adjusting the flow rate of the hot water flowing through the heating pipe 10a, and a mist valve comprising an electromagnetic on-off valve at the upstream end of the mist hot water supply path 9. 13 is provided, and a hot water temperature sensor 14 for detecting the temperature of the hot water heated by the heat absorbing pipe 10b is provided. These flow control valve 12 and mist valve 13 are controlled by a controller 15 comprising a macro computer provided in the mist heating unit 8 as will be described in detail later. The controller 15 receives a signal from the hot water temperature sensor 14 and a signal from a remote controller 16 installed in the bathroom 1.

  The remote controller 16 is a HOT switch 16a for instructing an operation (mist operation) in a state in which hot water mist is ejected from the spray head 7 into the bathroom 1, and an operation in a state in which cold water mist is ejected from the spray head 7 into the bathroom 1. A COLD switch 16b for instructing (cool down operation), a temperature switch 16c for setting the temperature of hot water supplied to the spray head 7, an up / down switch 16d, and a display unit 16e are provided. When the HOT switch 16a is pressed, the standard setting time of the mist operation is displayed on the display unit 16e so that the setting time can be changed by operating the up / down switch 16d. When the temperature switch 16c is pressed, The standard set temperature of hot water supplied to the spray head 7 is displayed on the display unit 16e, and the set temperature can be changed by operating the up / down switch 16d.

  As shown in FIGS. 3 and 4, the spray head 7 includes a straight inflow pipe portion 71 that connects piping members constituting the mist hot water supply passage 9, and a block-like head provided at the tip of the inflow pipe portion 71. A nozzle holder 70 having a portion 72, and a plurality of, for example, two mist nozzles 73 and 73 attached to the head portion 72 of the nozzle holder 70 are provided. Both the mist nozzles 73, 73 have a phase difference of 90 ° in the circumferential direction of the head portion 72, and the head portion 72 so that the nozzle hole 73 a of each mist nozzle 73 crosses the axis of the inflow pipe portion 71. It is fixed by screwing.

  At the base end of the head portion 72 on the inflow tube portion 71 side, a flange portion 72 a is formed that projects outward in the radial direction along a surface orthogonal to the axis of the inflow tube portion 71. And the through-hole 1b for the inflow pipe part 71 is formed in the wall surface 1a of the bathroom 1 which should attach the spray head 7, and the flange part 72a is made to contact | abut to the wall surface 1a. Here, when the nozzle holder 70 is rotated about the axis of the inflow pipe portion 71, the direction of the nozzle hole 73a of the mist nozzle 73 obliquely intersecting the axis changes. When installing the spray head 7, the phase of the nozzle holder 70 is determined so that the nozzle hole 73 a of the mist nozzle 73 faces a desired direction. After the spray head 7 is installed, the hot water mist is actually ejected from the mist nozzle 73. In some cases, the mist ejection direction does not match the desired direction, and the phase of the nozzle holder 70 needs to be corrected.

  In this case, if the flange portion 72a is screwed directly to the bathroom wall surface 1a, the set screw of the flange portion 72a is once removed and the flange portion 72a is screwed again to the bathroom wall surface 1a after the phase correction of the nozzle holder 70. I need it. In addition, when the screw is fastened again, it is necessary to re-apply the sealant to the set screw, and the phase correction operation of the nozzle holder 70, that is, the correction operation of the mist ejection direction becomes very troublesome.

  Therefore, in this embodiment, an annular pressing member 74 that can be engaged with the outer surface of the flange portion 72a on the head portion 72 side is provided, and a set screw 74b is screwed into the bathroom wall surface 1a through an attachment hole 74a formed in the pressing member 74. The nozzle holder 70 is fixed to the wall surface 1a by screwing the pressing member 74 to the bathroom wall surface 1a so that the flange portion 72a is sandwiched between the bathroom wall surface 1a. According to this, the nozzle holder 70 can be rotated and its phase can be corrected only by loosening the set screw 74b slightly and releasing the clamping pressure of the flange portion 72a. Accordingly, the correction operation in the mist ejection direction can be performed without removing the set screw 74b, and the correction operation is facilitated without the need to re-apply the sealant to the set screw 74b.

  Further, in the present embodiment, the inflow pipe portion 71 is divided into a half portion 71a on the front end side continuous with the head portion 72 and a half portion 71b on the tail end side, and the half portion 71b on the tail end side is used for the piping member. A connecting portion 71c is formed. The tip end of the tail end half 71b is rotatably fitted to the tip half 71a with an O-ring 71d attached to the outer periphery thereof. According to this, even if the nozzle holder 70 is rotated, it is connected to the tail-side half 71b by the relative rotation between the tip-side half 71a and the tail-end half 71b of the inflow pipe 71. The piping member is not twisted, and the restoring torque due to the twisting reaction force of the piping member does not act on the nozzle holder 70. Therefore, even if the hand of the nozzle holder 70 is released after the phase of the nozzle holder 70 is corrected, the nozzle holder 70 remains in the corrected phase, and the nozzle holder 70 is manually moved during the tightening operation of the set screw 74b of the holding member 74. There is no need to hold it down, which makes the work easier.

  In addition, the spray head 7 incorporates a check valve 75 that allows the flow of hot water from the mist hot water supply path 9 to the mist nozzle 73. In this embodiment, the check valve 75 is mounted in the half portion 71 a on the distal end side of the inflow pipe portion 71. In detail, the check valve 75 includes a cylindrical case 75a fitted in the half portion 71a on the distal end side of the inflow pipe portion 71, and a tapered valve seat portion 75b on the inner periphery of the case 75a. The valve body 75c that can be seated, a guide 75d that supports the valve body 75c so as to be movable in the axial direction, and a spring 75e that urges the valve body 75c in the axial direction to seat on the valve seat portion 75b. Yes.

  According to this, when hot water is supplied from the mist hot water supply passage 9, the valve body 75c is pushed forward in the axial direction against the urging force of the spring 75e, and the check valve 75 is opened. The hot water flows toward the mist nozzle 73. When the hot water supply from the mist hot water supply passage 9 is stopped, the valve body 75c is seated on the valve seat portion 75b by the biasing force of the spring 75e, and the check valve 75 is turned on. Is closed. Therefore, even if outside air enters from the nozzle hole 73a of the mist nozzle 73 when the mist operation is stopped, the check valve 75 prevents the staying water in the mist hot water supply passage 9 from coming into contact with the outside air. In this way, bacteria and the like are not mixed in from the outside air, and the propagation of bacteria in the staying water is prevented. Therefore, it is possible to prevent the contaminated water from being sprayed at the start of the mist operation. Moreover, since it is not necessary to drain the stagnant water in the hot water supply channel 9 for mist in order to prevent the propagation of bacteria in the stagnant water, it is advantageous that no noise is generated during drainage.

  The spray head 7 includes a hemispherical cover 76 that covers the head portion 72 (not shown in FIG. 3), and each mist nozzle 73 faces each through-hole 76a formed in the cover 76 as a pair. The cover 76 is detachably locked to the presser member 74 at the base end claw portion 76b.

Next, control during the mist operation by the controller 15 of the mist heating unit 8 will be described with reference to FIG. When an operation to turn on the HOT switch 16a of the remote control 16 (instruction operation for mist operation) is performed (S1), the controller 15 issues an operation command to the heat source unit 4 to circulate hot water in the bypass circulation path 11. At the same time (S2), the delay timer built in the controller 15 is reset and the timer operation is started (S3). After the HOT switch 16a is turned on, the up / down switch 16d is operated to change the setting time of the mist operation, or the temperature switch 16c is pressed to change the set temperature of the hot water supplied to the spray head 7. If this happens (S4), the process returns to the step of S3 to reset the delay timer again and start the timing operation. Also, once the setting change operation is performed, the process returns to the step of S3, and then the process returns from the step of S4 to the step of S5 without performing the setting change operation until the delay timer expires. Then, it is determined again whether a setting change operation has been performed. Therefore, the delay timer is reset every time a setting change operation is performed until the delay timer expires, and the clocking operation is started again.

  When the delay timer expires (S5), the mist valve 13 is opened (S6), and the supply of hot water to the spray head 7 is started. Thus, the supply timing of the hot water to the spray head 7 is always delayed by a fixed time determined by the delay timer from the time when the operation of the remote controller 16 (including the time and temperature setting change operation) is performed. The predetermined time is set to a time (for example, 10 seconds) that allows the user to evacuate outside the bathroom 1 after operating the remote controller 16 in the bathroom 1. Therefore, even if a user who wants to heat the bathroom in advance by bathing hot water mist before taking a bath enters the bathroom 1 while operating clothes and operates the remote controller 16, the mist is removed before retreating from the bathroom 1. It is surely prevented that clothes get wet by being ejected. In particular, even if it takes time to change the time and temperature settings, the delay timer is reset by this setting change operation, so mist does not spout during the setting change operation, and the setting change operation can be performed without panic. This makes it easy to change the setting.

  After the mist valve 13 is opened, temperature control is performed to maintain the temperature of the hot water supplied to the spray head 7 at a set temperature (S7). In the temperature control, the flow rate control valve 12 is a control target, and the flow rate of high-temperature hot water to be circulated through the bypass circulation path 11, that is, the amount of heating in the liquid heat exchanger 10 is determined between the detected temperature of the hot water temperature sensor 14 and the set temperature. Change based on deviation. In addition, the temperature of the hot water circulated through the bypass circulation path 11 is controlled to be constant by the heat source unit 4. Thereafter, when the set time for the mist operation has elapsed (S8), a stop command is issued to the heat source unit 4 to stop the circulation of hot water in the bypass circulation path 11 (S9), and the mist valve 13 is closed. (S10), mist operation is completed.

  In the above embodiment, the heating means for heating the hot water supplied to the spraying head 7 is constituted by the liquid heat exchanger 10, but the heating means is constituted by a heat source for hot water supply and is heated by the heat source machine. It is also possible to supply hot water to the spray head 7.
