  In this way, the bathroom system 1 to which the pipe switching unit and the indoor environment adjustment (control) system are applied is configured. Hereinafter, an example of the internal configuration of the electromagnetic valve unit 2A and a control example thereof will be described.

<Solenoid valve unit>
2A and 2B are front views showing a configuration example of the first and second electromagnetic valve units 2A and 2A2. The electromagnetic valve unit 2A shown in FIG. 2A has a housing 2A ′. In this example, when one side surface of the housing 2A ′ is opened, the arrangement of the electromagnetic valves in the electromagnetic valve unit can be seen.

  In the housing 2A ′, the connecting portion 2a ′ for connecting the water supply pipe 2a described above, the connecting portion 2b ′ for connecting the nozzle pipe 2b in the same manner, and the connecting portion 2c for connecting the drain pipe 2c. ′ Is attached and fixed. In this example, when the solenoid valve unit 2A is placed on the reference surface, the connection portion 2c 'is attached to the height H1 from the reference surface, and the connection portion 2a and the connection portion 2b' are attached to the height H2 from the reference surface. It is attached. The relationship between the two heights is H2> H1. That is, the three connection portions 2a ′ to 2c ′ are attached with the connection portion 2a ′ = connection portion 2b ′ at a position higher than the connection portion 2c ′.

  In this example, an electromagnetic valve 2d for water supply or hot water supply, which is an example of a water supply valve or a hot water supply valve, is attached to the connection portion 2a 'inside the housing 2A', and water or hot water I from the hot water supply device 4 is supplied. To be made. A mist nozzle electromagnetic valve 2e, which is an example of a first valve, is attached to the pipe 2j connected to the electromagnetic valve 2d, and water or hot water I is supplied to the nozzle unit 2C. The downstream side (the other end) of the electromagnetic valve 2e is attached to the connection portion 2b ′.

  At a position lower than the solenoid valve 2e, a drainage solenoid valve 2f as an example of the second valve is disposed and attached to the other pipe 2k branched from the pipe 2j. I will do it. The downstream side (the other end) of the electromagnetic valve 2f is attached to the connecting portion 2c ′. That is, one end of the electromagnetic valve 2d is connected to the connection portion 2a ', and one end of the electromagnetic valve 2e is connected to the other end of the electromagnetic valve 2d via the pipe 2j. The other end of the electromagnetic valve 2e is connected to the connection portion 2b ′. Furthermore, the pipe 2k branched from the pipe 2j is connected to one end of the electromagnetic valve 2f, and the connecting portion 2c 'is connected to the other end of the electromagnetic valve 2f.

  As a result, the electromagnetic valve 2f connected to the connection portion 2c ′ having the height H1, the electromagnetic valve 2d connected to the connection portion 2a ′ at the height H2, and the electromagnetic valve 2e connected to the connection portion 2b ′. The relationship between the three heights can be H2> H1. That is, the three solenoid valves can be arranged at a position higher than the solenoid valve 2f so that the solenoid valve 2e = the solenoid valve 2d.

  In addition to the solenoid valves 2d, 2e, and 2f, a temperature detection sensor 2h is disposed inside the solenoid valve unit 2A. The temperature detection sensor 2h is attached to the pipe 2j, for example, and detects the temperature of the hot water I (hot water I) flowing through the pipe 2j after passing through the electromagnetic valve 2d and outputs a temperature detection signal S7. The The temperature detection signal S7 is output from the temperature detection sensor 2h to the power supply unit 2B. For convenience, the power supply unit 2B is drawn out to the outside. In this example, the power supply unit 2B is mounted inside or on the side surface of the housing 2A ′, and includes a power transformer, a leakage breaker, and a control constituting the power supply unit 2B. A substrate or the like is formed (distributed) integrally with the electromagnetic valve unit 2A.

<Power supply unit>
The electromagnetic valve 2d, the electromagnetic valve 2e, and the electromagnetic valve 2f described above are connected to the power supply unit 2B, and these electromagnetic valves are individually controlled to be opened and closed. For example, in the power supply unit 2B, the supply of hot water I from the mist remote controller 7 is stopped when the electromagnetic valve 2f is closed and the hot water I from the hot water supply device 4 is flowing through the electromagnetic valve 2d and the electromagnetic valve 2e. For example, when the mist stop signal S7 is input, the electromagnetic valve 2f is opened and the electromagnetic valve 2e is closed. After a predetermined time has elapsed, the electromagnetic valve 2d is closed, and then the electromagnetic valve 2e is opened. After a predetermined time has elapsed, control is performed to close the solenoid valve 2e and close the solenoid valve 2f. The mist stop signal S7 is an input for stopping the supply of hot water from the hot water supply device 4.

  The second electromagnetic valve unit 2A2 shown in FIG. 2B is configured (designed) such that the housing 2A ′ is lower than the overall height of the first electromagnetic valve unit 2A. In this example, when the solenoid valve unit 2A2 is placed on the reference plane, the connection portion 2c 'is attached to the height H1 from the reference plane in the same manner as the first solenoid valve unit 2A. A connecting portion 2a and a connecting portion 2b 'are attached to H2'. The relationship between the two heights is H2 '> H1, and the relationship with the first electromagnetic valve unit 2A is H2' <H2.

  If the housing 2A ′ is configured in this way, the low-position electromagnetic valve unit 2A2 can sufficiently cope with the case where the back space of the bathroom ceiling is not sufficient. For example, in a high-rise house, etc., it is possible to cope sufficiently when the distance between the back of the ceiling of the unit bath (bathroom) and the lower floor (slab) of the upper floor is short and there is no room in the height direction. Become. A pressure sensor 2q is connected between the connecting portion 2a 'and the electromagnetic valve 2d, detects the pressure of the hot water I, and inputs the pressure information to the hot water supply device 4 to control the water pressure of the hot water I. . In addition, since the thing of the same code | symbol and the same name as the 1st solenoid valve unit 2A have the same function, the description is abbreviate | omitted.

  3 and 4 are diagrams showing operation examples (parts 1 and 2) of the electromagnetic valve unit 2A. For example, during the mist operation, the hot water solenoid valve 2d shown in FIG. 3A is opened, so that the hot water I from the water supply pipe 2a (see FIG. 1) passes through the solenoid valve 2d and the pipe 2j from the connecting portion 2a ′. It is supplied to the electromagnetic valve 2e. By opening the solenoid valve 2e, the hot water I is supplied to the nozzle pipe 2b (see FIG. 1) through the pipe 2j, the solenoid valve 2e, and the connecting portion 2b ′. The hot water I is ejected from the mist nozzle unit 2C. At this time, the electromagnetic valve 2f for drainage remains closed.

  In the drainage control when the mist operation is stopped, the electromagnetic valve 2f shown in FIG. 3B is first opened and the electromagnetic valve 2e is closed. Thereby, the hot water I is drained into the drain pipe 2c through the pipe 2k, the electromagnetic valve 2f, and the connection portion 2c ′. This state is a state where the inside of the drain pipe 2c is temporarily filled with the hot water I and deaerated without depending on the atmospheric pressure.

  Next, as shown in FIG. 4A, the electromagnetic valve 2d is closed after a predetermined time while the electromagnetic valve 2f is opened. In this example, the hot water solenoid valve 2d is closed after 2 seconds. As a result, the residual water (water) II from the connection pipe 2b ′ reaches the electromagnetic valve 2f through the pipes 2j and 2k and is drained to the drain pipe 2c. At this time, since the solenoid valve 2e remains open, the air III is taken into (drawn into) the solenoid valve 2e and the pipes 2j and 2k through the connection pipe 2b ′. Thereby, the residual water II in the connection pipe 2b ′, the electromagnetic valve 2e, the pipes 2j and 2k can be discharged to the outside of the bathroom through the electromagnetic valve 2f.

  In this example, the electromagnetic valve 2e for mist is controlled to close after a predetermined time, for example, 3 seconds, and to close the electromagnetic valve 2f for drainage. As a result, as shown in FIG. 4B, all the electromagnetic valves 2d, 2e, and 2f in the electromagnetic valve unit are closed. It waits for the next mist operation.

  FIG. 5 is a flowchart illustrating an example of control in the power supply unit 2B. In this example, the drainage control (drainage valve timing) of the bathroom (mist) unit 1 is optimized to perform valve control that does not cause residual water in the pipe. A read-only memory (not shown) of the power supply unit 2B describes a program relating to drainage control after the mist operation stop (hereinafter referred to as a control program), and the solenoid valve 2d from when there is a stop command in the program. An example is given in which the predetermined time t1 to reach the closing operation is set to 2 seconds and the predetermined time t2 from the reopening of the electromagnetic valve 2e to the reclosing is set to 3 seconds.

  Under this control condition, the power supply unit 2B waits for a stop command in step ST1 of the flowchart shown in FIG. The stop command is notified, for example, by outputting a mist stop signal S7 requesting the supply stop of the hot water I from the mist remote controller 7 to the power supply unit 2B.

  When the power supply unit 2B receives the mist stop signal S7, based on the control program, the electromagnetic valve 2f for drainage is turned on while the hot water solenoid valve 2d is turned on in step ST2. For example, a predetermined drive voltage V2f is applied to the electromagnetic valve 2f through an electromagnetic valve driving unit (not shown) to open the valve.

  Next, the power supply unit 2B turns off the electromagnetic valve 2e for mist in step ST3 based on the control program. For example, the predetermined drive voltage V2e applied to the electromagnetic valve 2e through an electromagnetic valve drive unit (not shown) is set to 0 [V], and the valve is closed.

  Next, the power supply unit 2B determines whether t1 time has elapsed in step ST4. In this example, when t1 = 2 seconds have not elapsed, the process waits as it is. When t1 = 2 seconds have elapsed, the process proceeds to step ST5 and the solenoid valve 2d for hot water supply is turned off. Similarly, the predetermined drive voltage V2d applied to the electromagnetic valve 2d is set to 0 [V], and the valve is closed.

  In step ST6, the mist solenoid valve 2e is turned off. Similarly, the predetermined drive voltage V2e applied to the electromagnetic valve 2e is set to 0 [V], and the valve is closed. Thereafter, the power supply unit 2B determines whether t2 time has elapsed in step ST7. In this example, if t2 = 3 seconds has not elapsed, the process waits as it is. When t2 = 3 seconds have elapsed, the process proceeds to step ST8.

  In step ST8, the power supply unit 2B turns off the mist solenoid valve 2e. For example, the predetermined drive voltage V2d applied to the electromagnetic valve 2d through the electromagnetic valve driving unit is set to 0 [V], and the valve is closed. Next, the power supply unit 2B turns off the electromagnetic valve 2f for drainage at step ST9. Similarly, the predetermined drive voltage V2f applied to the electromagnetic valve 2f is set to 0 [V] to close the valve. As a result, as shown in FIG. 4B, all the electromagnetic valves 2d, 2e, and 2f in the electromagnetic valve unit are closed.

  Thus, according to the bathroom system 1 provided with the electromagnetic valve unit 2A according to the present invention, the power supply unit 2B is configured such that the electromagnetic valve 2f is closed and the hot water I from the water heater 4 is ejected through the electromagnetic valve 2e. When there is a command to stop the supply of the hot water I from the hot water supply device 4, the other pipe 2k branched from the pipe 2j of the electromagnetic valve 2d is temporarily filled with the hot water I. The hot water I in the pipe line 2k can flow to the drain pipe 2c through the solenoid valve 2f, and the drained air is drawn from the solenoid valve 2e, so that there is no dripping from the solenoid valve 2e, and the pipe It will be possible to prevent water remaining on the road.

<Nozzle unit>
6 and 7 are diagrams illustrating a configuration example of the nozzle unit 2C. FIG. 6 is a perspective view illustrating a configuration example (at the time of disassembly) of the nozzle unit 2C, and FIGS. 7A to 7C are a top view illustrating the configuration example, a front view and a side view of partial crushing. 7A to 7C show a state where the screws 2E1 to 2E4 are removed.

  The nozzle unit 2C shown in FIG. 6 includes a main unit 2Cd, a front panel 2Da, a water supply pipe section 2Ca, nozzles 2m1, 2m2, and 2m3, and a pipe connection section 2n so as to eject (spray) hot water I and water. To be made. The water supply pipe section 2Ca is mounted (mounted) in the main body unit 2Cd, and the nozzles 2m1, 2m2, and 2m3 are exposed at their heads from the openings 2Da1, 2Da2, and 2Da3 provided at predetermined positions of the front panel 2Da. The piping connection portion 2n is drawn out from one end of the main unit 2Cd.

  The main unit 2Cd has a box shape with a flange and a long bottom, and for example, a molded product obtained by molding an ABS resin with an injection mold apparatus is used. The main unit 2Cd is fixed to the ceiling surface of the bathroom 101. In this example, an opening that is slightly larger than the outer peripheral shape of the box part of the main unit 2Cd and smaller than the collar part is opened on the ceiling surface, and the main unit 2Cd is fitted from the front side of the ceiling toward the back of the ceiling, The periphery is fixed to a ceiling member or a dedicated backing member by screws (see FIG. 8B).

  The front panel 2Da shown in FIG. 7A constitutes an example of a flat member for the front surface, and includes a jetting direction variable mechanism that changes the tip positions of the nozzles 2m1, 2m2, and 2m3 as the front panel 2Da slides in a predetermined direction. Have. As shown in FIG. 6, the front panel 2Da is movably attached so as to cover the open surface (nozzle end exposed) side of the main unit 2Cd.

  Slide guide grooves 2Db1 to 2Db4 are provided at predetermined portions (four corners) on both ends of the front panel 2Da. In this example, the front panel 2Da is handled so as to slide (slide) in a predetermined direction with reference to (along) the slide guide grooves 2Db1 to 2Db4. Each of the slide guide grooves 2Db1 to 2Db4 is configured to have a long and narrow elliptical hole and a long and narrow elliptical hole that is slightly smaller than that. In slide guide grooves (sliding guide grooves) 2Db1 to 2Db4, screws 2E1 to 2E4 are screwed to the main unit 2Cd and used. The screws 2E1 to 2E4 constitute an example of an engaging member (see FIG. 6). For the front panel 2Da, for example, a molded product obtained by molding a resin such as a plastic with an injection mold apparatus is used.

  The front panel 2Da is provided with a plurality of openings 2Da1, 2Da2, and 2Da3. In this example, the tip of the nozzle 2m1 is engaged with the opening 2Da1, the tip of the nozzle 2m2 is engaged with the opening 2Da2, and the tip of the nozzle 2m3 is engaged with the opening 2Da3. When sliding, these nozzles 2m1, 2m2, and 2m3 are engaged. An abutting force (rotational force) is applied to the tip.

  The openings 2Da1, 2Da2, and 2Da3 have a mortar shape (horn shape or cone shape) that is an example of a concave shape that spreads outward, and a slope (R shape) is provided on the inner wall thereof. Further, the tips of the nozzles 2m1, 2m2, and 2m3 are set so as to be disposed at or below the surface positions of the concave openings 2Da1, 2Da2, and 2Da3. In other words, the nozzles 2m1, 2m2, and 2m3 have a flat design (structure) that does not protrude from the surface position (equal or less). This is to prevent the hot water I or the water spraying direction from being obstructed (not to be a barrier) when the nozzles 2m1, 2m2, and 2m3 are rotated.

  Bearing portions 2Cb1 and 2Cb2 are provided on both longitudinal sides of the main unit 2Cd shown in FIG. 7B. The bearing portions 2Cb1 and 2Cb2 pivotally support (engage) the rotating water supply pipe portion 2Ca. The water supply pipe portion 2Ca has a length reaching the bearing portions 2Cb1 and 2Cb2 on both sides of the main body unit 2Cd in order to form a rotation axis along the longitudinal direction. A copper pipe or a brass pipe is used for the water supply pipe portion 2Ca.

  Nozzles 2m1, 2m2, and 2m3 are drawn out in series through the connecting members 2Ce1, 2Ce2, and 2Ce3 from a predetermined position of the water supply pipe portion 2Ca, in this example, one in the center and one on each side. . For the connecting members 2Ce1, 2Ce2, and 2Ce3, a copper square (rectangular) or a brass square (rectangular) is used. Of course, the material is not limited to metal, and a hard resin may be used.

  In this example, the water supply pipe portion 2Ca and each of the connection members 2Ce1, 2Ce2, 2Ce3 are joined in a form penetrating a predetermined position of the connection members 2Ce1, 2Ce2, 2Ce3. The nozzle 2m1 is connected to the connection member 2Ce1, the nozzle 2m2 is connected to the connection member 2Ce2, and the nozzle 2m3 is connected to the connection member 2Ce3. Any of the nozzles 2m1, 2m2, and 2m3 and the water supply pipe portion 2Ca are brazed and joined (connected) to the connection members 2Ce1, 2Ce2, and 2Ce3 with solder or silver.

  In this example, the nozzle 2m1 shown in FIG. 7B is attached with an inclination angle set by θ1 on the left hand side, and the nozzle 2m2 is attached with an inclination angle set by θ2 on the right hand side. The nozzle 2m3 is provided in a direction orthogonal to the water supply pipe portion 2Ca. The reason why the inclination angles θ1 and θ2 are set in this manner is to extend the spray (divergence) range of the hot water I and water as the entire nozzle unit 2C.

  The bearing 2Cb2 shown in FIG. 7C includes a connection 2n for connecting the nozzle pipe 2b (see FIG. 1). The hot water I supplied to the connecting portion 2n from the nozzle pipe 2b is supplied to the nozzles 2m1, 2m2, and 2m3 through a pipe in the bearing portion 2Cb2 (not shown) and a pipe in the water supply pipe portion 2Ca shown in FIG. Erupted as.

  8A and 8B are configuration diagrams illustrating an example of a driving mechanism of the nozzle unit 2C. The water supply pipe portion 2Ca shown in FIG. 8A has a structure that can swing left and right with respect to the rotation axis. For example, a gear unit 86 shown in FIG. 8A is attached to the water supply pipe section 2Ca, and a motor 73 for rotating the gear unit 72 is provided. Such a direct drive mechanism 71 constitutes an example of a drive means, and controls the nozzles 2m1, 2m2, and 2m3 to face in a predetermined direction by rotating the water supply pipe portion 2Ca. This type has an advantage that all mechanical parts can be mounted inside the main unit 2Cd.

  On the other hand, the main part of the drive mechanism 81 (drive means) is provided on the side surface of the main unit 2Cd shown in FIG. 8B, and the front panel 2Da shown in FIG. It is made to slide along. For example, the rack rail 82 is attached to the back surface of the front panel 2Da in a direction orthogonal to the water supply pipe portion 2Ca. A gear 83 is meshed with the rack rail 82. A motor 84 serving as power for the gear 83 is provided inside or outside the main unit 2Cd. The motor 84 is driven to drive (slide) the front panel 2Da in a direction orthogonal to the water supply pipe portion 2Ca.

  By sliding the front panel 2Da, the tip of the nozzle 2m1 engaged with the opening 2Da1 shown in FIG. 7A, the tip of the nozzle 2m2 engaged with the opening 2Da2, and the opening 2Da3 are engaged. The front end of the nozzle 2m3 and the like is given a contact force (rotation power) by the slide of the front panel 2Da, and the nozzles 2m1, 2m2, and 2m3 are hooked on these openings 2Da1, 2Da2, and 2Da3, so that the direction of the front end of the nozzle is changed. To be made. In this way, in comparison with the former direct drive mechanism 71, the indirect drive mechanism 81 has a lower torque by the length of the arm extending from the center of the water supply pipe portion 2Ca to the nozzle tip. 2m1, 2m2, and 2m3 can be controlled to face in a predetermined direction, and both can provide an automatic nozzle tip direction adjusting mechanism.

  Of course, it is good also as a structure which can switch a jetting direction arbitrarily manually, without providing the drive mechanisms 71 and 81 etc. for rotationally driving such water supply pipe part 2Ca. For example, when setting the spray angle, first, the screws 2E1 to 2E4 shown in FIG. 6 are loosened. Next, when the front panel 2Da is pushed in a desired direction, the panel 2Da is slid along the slide guide grooves 2Db1 to 2Db4, and the nozzles 2m1, 2m2, and 2m3 are caught in the openings 2Da1, 2Da2, and 2Da3. When the nozzle tip direction is changed and the tip positions of these nozzles 2m1, 2m2, and 2m3 are determined, the front panel 2Da is fixed to the main unit 2Cd with screws 2E1 to 2E4.

  In this way, the spray angle of the nozzle unit 2C is kept at that position. In this operation, even after the construction of the bathroom 101, the user can adjust the nozzle tip direction to an angle according to the preference by loosening 2E1 to 2E4 and sliding the front panel 2Da (semi-fixed method).

  FIGS. 9-11 is a block diagram which shows the operation example (the 1-3) of the nozzle unit 2C in the bathroom system 1. FIG. 9A and 9B are an elevation view and a front sectional view showing an example of the posture of the nozzles 2m1, 2m2, and 3m3 at the home position HP of the nozzle unit 2C.

  In this embodiment, a bathroom air conditioner 3 that adjusts the temperature in the bathroom 101 and a nozzle unit with a spray direction variable mechanism that jets hot water I or water into the bathroom 101 whose temperature is adjusted by the bathroom air conditioner 3. 2C is provided separately on the ceiling surface. The nozzle unit 2C is installed on the ceiling surface of the bathroom 101 in the bathroom 101, and the bathroom air conditioner 3 is arranged on the ceiling surface of the bathtub 101b.

  The bathroom air conditioner 3 shown in FIG. 9A has a front panel 26, and the nozzle unit 2C has a front panel 2Da. When looking up at the ceiling surface of the bathroom 101, the front panel 26 of the bathroom air conditioner 3 and the front panel 2Da of the nozzle unit 2C are arranged with a predetermined distance therebetween.

  In this example, the position of the front panel 2Da with respect to the main body unit 2Cd of the nozzle unit 2C shown in FIG. 9B is the home position HP of the nozzle unit 2C. According to the posture example of the nozzles 2m1, 2m2, and 3m3 at the home position HP, the nozzle 2m3 disposed at the center is set to a position facing directly below. The nozzles 2m1 and 2m2 arranged on both sides thereof are inclined to the both sides from directly below.

  This position is a state in which, for example, the screw 2E1 is located at the center of the slide guide groove 2Db1 in each of the slide guide grooves 2Db1 to 2Db4. Similarly, the screw 2E2 is located at the center of the slide guide groove 2Db2, the screw 2E3 is located at the center of the slide guide groove 2Db3, and the screw 2E4 is located at the center of the slide guide groove 2Db4. .

  In this example, the front panel 2Da of the nozzle unit 2C shown in FIG. 9B is set to be thinner than the front panel 26 of the bathroom air conditioner 3. Here, assuming that the thickness of the front panel 2Da of the nozzle unit 2C is a1, and the thickness of the front panel 26 of the bathroom air conditioner 3 is a2, a1 <a2. The filter 29 shown in FIG. 9 is replaceably attached to the insertion port 28 for attaching / detaching the filter of the front panel 26. In the figure, the time when the filter 29 is mounted is indicated by a solid line, and the time when the filter 29 is drawn is indicated by a two-dot chain line (see FIG. 13).

  If the thickness a1 of the front panel 2Da is made thinner than the thickness a2 of the front panel 26 in this way, the tip of the filter 29 can be pulled out without interfering with the front panel 2Da when the filter of the bathroom air conditioner 3 is replaced. This is because the replacement workability is improved and the short circuit effect during hot air circulation in the bathroom air conditioner 3 can be prevented. Here, the short circuit effect refers to hot water I or wraparound of water due to the formation of a short circuit path connecting the air inlet of the bathroom air conditioner 3 and the opening of the front panel 2Da.

  10A and 10B are an elevation view and a front sectional view showing examples of postures of the nozzles 2m1, 2m2, and 3m3 at the right slide position of the front panel 2Da.

  The posture example of the nozzles 2m1, 2m2, and 3m3 shown in FIG. 10A is a posture that is taken after the front panel 2Da is slid to the right from the home position HP. In FIG. 10B, the position of the front panel 2Da with respect to the main body unit 2Cd of the nozzle unit 2C is the right slide position.

  According to this posture example of the right slide position, the nozzle 2m3 arranged at the center and the nozzles 2m1, 2m2 arranged above and below are both inclined to the right by an angle φ1. This position is a state in which the screw 2E1 is located on the left end side of the slide guide groove 2Db1 in each of the slide guide grooves 2Db1 to 2Db4. Similarly, the screw 2E2 is located on the left end side of the slide guide groove 2Db2, the screw 2E3 is located on the left end side of the slide guide groove 2Db3, and the screw 2E4 is located on the left end side of the slide guide groove 2Db4. .

  In this example, the spray range can be extended to the washing place side (not shown). Further, when the filter of the bathroom air conditioner 3 shown in FIG. 10B is replaced, the front end of the filter 29 is further moved to the right slide position by moving the front panel 2Da to the right slide position as compared with the case where the filter 29 is fixed at the home position HP. As shown in B), it can be pulled out without interfering with the front panel 2Da, and the replacement workability is further improved. This is because the space between the front panel 2Da of the nozzle unit 2C and the front panel 26 of the bathroom air conditioner 3 is wider than when it is fixed at the home position HP.

11A and 11B are an elevation view and a front sectional view showing examples of postures of the nozzles 2m1, 2m2, and 3m3 at the left slide position of the front panel 2Da.
The posture examples of the nozzles 2m1, 2m2, and 3m3 illustrated in FIG. 11A are postures that are taken after the front panel 2Da is slid from the home position HP to the left side. In FIG. 11B, the position of the front panel 2Da with respect to the main body unit 2Cd of the nozzle unit 2C is the left slide position.

  According to this posture example of the left slide position, the nozzle 2m3 arranged at the center and the nozzles 2m1, 2m2 arranged above and below are both inclined to the left side by an angle φ2. This position is a state in which the screw 2E1 is located on the right end side of the slide guide groove 2Db1 in each of the slide guide grooves 2Db1 to 2Db4. Similarly, the screw 2E2 is located on the right end side of the slide guide groove 2Db2, the screw 2E3 is located on the right end side of the slide guide groove 2Db3, and the screw 2E4 is located on the right end side of the slide guide groove 2Db4. .

  In this example, the spray range can be expanded to the bathroom air conditioner side shown in FIG. 11B, that is, above the bathtub 101b (not shown). Therefore, the user can experience the mist sauna with hot water I or water while entering the bathtub 101b.

  Thus, according to the bathroom system 1 according to the present invention, since the nozzle unit 2C of the present invention is provided, the ejection angles of the nozzles 2m1, 2m2, and 2m3 are interlocked with the sliding operation of the front panel 2Da in a predetermined direction. You can adjust all at once.

  Therefore, regarding the ceiling-installed mist sauna system, the ejection angles of the nozzles 2m1, 2m2, and 2m3 can be arbitrarily selected according to the user's preference whether or not to take mist on the body. In addition, since the front panel 2Da is provided with a manual type or drive mechanism, the mist spraying direction can be changed during installation or use.

  As a result, during the operation of the mist sauna, it is possible to provide a structure that can change the jet direction of the hot water I or water in real time and can make the mist sauna state in a wider range than when the rotation is stopped. This structure is suitable for application to a mist sauna system of the bathroom 101 that is wider than the conventional system. The nozzle unit 2c is not only attached to the bathroom wall, but may be integrated with a bathroom air conditioner described later.

<Bathroom air conditioner>
12 and 13 are diagrams illustrating a configuration example of the bathroom air conditioner 3. FIG. 12 is a cross-sectional view showing an example of the internal configuration of the bathroom air conditioner 3.

  The bathroom air conditioner 3 shown in FIG. 12 includes a fan unit 32 and a heater unit 33 as a heat source. The fan unit 32 is attached to the main body case 34. The fan unit 32 includes a multiblade fan 35 that is rotationally driven, a fan motor 36 that rotationally drives the fan 35, and a fan case 37 that is mounted with the fan motor 36 and forms an air passage. .

  The fan 35 is arranged vertically. A lower surface of the fan case 37 along the axial direction of the fan 35 is opened and serves as a suction port 38. A temperature detection sensor 69 constituting an example of temperature detection means is attached to the suction port 38 so as to detect the temperature of the bathroom 101. A thermistor is used for the temperature detection sensor 69. In addition, one side surface of the fan case 37 along the direction orthogonal to the axial direction of the fan 35 opens, and an air path switching unit 39 is provided in the opening.

  The air path switching unit 39 includes a damper 40 that switches the air path. The damper 40 receives a driving force of a damper motor 40c, which will be described later, via a cam 40a, and rotates around the shaft 40b to open and close. The fan case 37 communicates with the air path switching unit 39 and includes a blower outlet 41 on the lower surface, and communicates with the air path switching unit 39 and includes an exhaust port 42 on one side surface. In this case, depending on the position of the damper 40, an air passage communicating from the suction port 38 to the air outlet 41 or an air passage communicating from the suction port 38 to the exhaust port 42 is formed.

  A heater portion 33 is attached to a predetermined position of the above-described air outlet 41 so as to heat the discharged air. An electric heater that constitutes a heating unit is used for the heater unit 33. By exhausting warm air from the air outlet 41 into the bathroom, the temperature of the mist is prevented from being lowered and the interior of the bathroom is heated.

The fan case 37 includes an ion generator 44 at a predetermined position of the suction port 38 on the upstream side of the heater unit 33. The ion generator 44 exposes the ion emission surface to the circulation air passage 43a formed by setting the damper 40 to the circulation position or the circulation ventilation position. The ion generator 44 generates both positive ions and negative ions or negative ions. The principle of generation of positive ions and negative ions is that corona discharge is caused by boosting and applying an AC voltage obtained from a household AC power source or the like between a pair of electrodes facing each other so that a dielectric is interposed. Oxygen or water in the air is ionized by receiving energy by ionization, and H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) ) Releases the main ions.

These H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n adhere to the surface of the floating bacteria and chemically react to generate H ₂ O ₂ or .OH as an active species. Since H ₂ O ₂ or .OH exhibits very strong activity, they can surround and remove airborne bacteria. Here, .OH is one kind of active species, and represents radical OH.

  Accordingly, in association with the operation of the fan unit 32, approximately the same number of positive ions and negative ions are generated, and air containing approximately the same number of positive ions and negative ions is blown, thereby allowing floating bacteria contained in the circulating air to 1 can be sterilized by inactivating both the floating bacteria in the air of the bathroom 101 shown in FIG. 1 and suppressing the generation of mold and the like.

  FIG. 13 is a perspective view showing an exploded example of the bathroom air conditioner 3. The bathroom air conditioner 3 shown in FIG. 13 has a structure in which the front panel 26 can be removed (disassembled) from the main body case 34.

  In this example, the temperature detection sensor 69 is attached to a portion corresponding to the suction port 38 of the main body case 34 and detects the temperature of the bathroom 101. In FIG. 13, the main body case 34 is opened at the lower surface so that the suction port 38 and the air outlet 41 are exposed. The front panel 26 is attached to the lower surface opening of the main body case 34. The front panel 26 is configured to be detachable from the main body case 34.

  The front panel 26 includes a suction grill 45 facing the suction port 38 of the fan part 32, and a blow grill 46 facing the blower outlet 41 of the fan part 32. Further, the filter 29 shown in FIG. 9 is replaceably attached to the back side of the suction grill 45 of the front panel 26. For example, an insertion port 28 for attaching / detaching a filter is opened on the side surface of the front panel 26, and a filter 29 indicated by a two-dot chain line is attached to the insertion port 28. The main body case 34 includes an exhaust duct connecting portion 48 that communicates with the exhaust port 42 of the fan portion 32 on one side surface. An exhaust duct 8 as shown in FIG. 1 is connected to the exhaust duct connection portion 48.

  14A to 14C are diagrams illustrating an operation example of the bathroom air conditioner 3. FIG. 14A is a cross-sectional view showing a state example in which the damper 40 is fully closed. In this example, when the damper 40 of the bathroom air conditioner 3 is fully closed, the air passage to the exhaust port 42 is blocked, and a circulation air passage 43 a communicating from the suction port 38 to the blower outlet 41 is formed. For this reason, the position where the damper 40 is fully closed is referred to as the circulation position of the damper 40.

  As shown in FIG. 14A, when the position of the damper 40 is set to the circulation position and the fan 35 is rotationally driven by the fan motor 36, air is sucked from the suction port 38 and blows out from the blower outlet 41 through the circulation air passage 43a. The fan motor 36 is driven by the drive voltage V36 supplied from the control unit 5A. At this time, when the heater unit 33 is energized, the heater unit 33 is heated to heat the air passing through the air outlet 41, and hot air is blown out from the air outlet 41. Here, as the heater section 33, for example, a PTC (Positive Temperature Coefficient) heater can be used.

  FIG. 14B is a cross-sectional view illustrating a state example in which the damper 40 is fully opened. According to the bathroom air conditioner 3 shown in FIG. 14B, when the damper 40 is fully opened, the air path to the air outlet 41 is blocked, and the ventilation air path 43 b communicating from the suction port 38 to the exhaust port 42 is formed. For this reason, the position where the damper 40 is fully opened is referred to as a ventilation position of the damper 40.

  FIG. 14C is a cross-sectional view showing an example of a state in which the damper 40 is at an intermediate position between the circulation position and the ventilation position. According to the bathroom air conditioner 3 shown in FIG. 14C, when the damper 40 is set at an intermediate position between the circulation position and the ventilation position, the circulation air passage 43a communicated from the air inlet 38 to the air outlet 41, and the air inlet 38 to the air outlet 42. Both ventilation air passages 43b communicated with each other are formed. This intermediate position is referred to as a circulation ventilation position.

  Subsequently, an operation example of the bathroom air conditioner 3 will be described. In the bathroom air conditioner 3, for example, when the fan motor 36 is driven to rotate, the fan 35 of the fan unit 32 rotates. When the fan 35 rotates, the air in the bathroom 101 is sucked from the suction port 38 of the fan part 32 through the suction grill 45 of the front panel 26.

  When the position of the damper 40 is at the circulation position shown in FIG. 14A, the circulation air passage 43a from the suction port 38 to the blowout port 41 is formed in the fan portion 32, so that the air sucked from the suction port 38 is The air passes through the passage 43a and is blown out into the bathroom 101 from the air outlet 41 through the air outlet grill 46 of the front panel 26.

  Since the heater portion 33 is disposed at the outlet 41 of the circulation air passage 43a, the air passing through the circulation air passage 43a is heated by the heater portion 33 and blown out from the outlet grill 46 by driving the heater portion 33. . As a result, when the fan motor 36 is rotationally driven with the damper 40 as the circulation position, when the heater unit 33 is driven, hot air is blown into the bathroom 101 while circulating the air in the bathroom 101. it can.

  When the position of the damper 40 is in the ventilation position shown in FIG. 14B, the ventilation air passage 43b from the suction port 38 to the exhaust port 42 is formed in the fan portion 32, so that the air sucked from the suction port 38 is ventilated. The air passes through the passage 43b and the exhaust port 42, and further passes through the exhaust duct 8 shown in FIG. 1 to be exhausted from the exhaust grill 8a to the outdoors. Thereby, when the fan motor 36 is rotationally driven with the damper 40 as the ventilation position, steam and moisture in the bathroom 101 are exhausted.

  When the position of the damper 40 is in the circulation ventilation position shown in FIG. 14C, both the circulation air passage 43 a from the suction port 38 to the blowout port 41 and the ventilation airflow passage 43 b from the suction port 38 to the exhaust port 42 in the fan portion 32. Thus, a part of the air sucked from the suction port 38 passes through the circulation air passage 43a and is blown out from the blower outlet 41 into the bathroom 101 through the blowout grill 46 of the front panel 26, and the other is a ventilation airway. 43 b and the exhaust port 42, and further through the exhaust duct 8 shown in FIG. 1 to be exhausted from the exhaust grill 8 a to the outdoors.

  Thereby, when the fan motor 36 is rotationally driven with the damper 40 as the circulation ventilation position, when the heater unit 33 is not driven, the steam and moisture in the bathroom 101 are exhausted while circulating the air in the bathroom 101. Is done. In addition, when the heater unit 33 is driven, steam and moisture in the bathroom 101 are exhausted while circulating air in the bathroom 101 and blowing hot air into the bathroom 101. The bathroom air conditioner 3 may be not only an electric type but also a hot water type.

<Heat pump type bathroom system 1>
FIG. 15 is a block diagram illustrating a configuration example of the heat pump type hot water supply apparatus 4. A hot water supply device 4 shown in FIG. 15 supplies hot water I to the mist generating device 2, the bathroom 101, the washroom 102, the kitchen 103, and the like shown in FIG.

The compressor 58 is disposed between the air heat exchanger 55 and the water heat exchanger 56 and is disposed on the downstream side of the air heat exchanger 55. The refrigerant is exchanged in the air heat exchanger 55 and flows through the refrigerant pipe 57. Used to compress the gas and raise the temperature further.

  The heat pump unit 53 is provided with an expansion valve 59 between the air heat exchanger 55 and the water heat exchanger 56 and on the downstream side of the water heat exchanger 56. The expansion valve 59 is used to expand the refrigerant gas flowing through the refrigerant pipe 57 after being heat-exchanged by the water heat exchanger 56 to lower the temperature.

  A hot water storage tank unit 54 is connected to the heat pump unit 53 and includes a tank 60 for storing hot water I generated by the heat pump unit 53. The tank 60 is supplied with water at the lower side and is supplied with hot water I at the upper side, and stores the hot water I in a stepped state in which the temperature on the upper side is higher than that on the lower side.

  The heat pump unit 53 and the hot water storage tank unit 54 are connected between the water heat exchanger 56 and the tank 60 by a hot water pipe 61a and a cold water pipe 61b. For example, the hot water pipe 61 a connects between the outflow side of the water heat exchanger 56 and the inflow port 60 a provided on the upper side of the tank 60. The cold water pipe 61 b connects between the inflow side of the water heat exchanger 56 and the outlet 60 b provided on the lower side of the tank 60.

  A pump 61c is attached to the cold water pipe 61b. The pump 61c sucks water from the outlet 60b of the tank 60 through the cold water pipe 61b and supplies the water to the water heat exchanger 56. The hot water I generated through the water heat exchanger 56 is passed through the hot water pipe 61a. To the tank 60 from the inlet 60a.

  In addition, a water intake pipe 62 and a water supply pipe 63 are connected to the tank 60. The intake pipe 62 is used for taking hot water I stored in the tank 60. The intake pipe 62 includes a high temperature part intake pipe 62a and an intermediate temperature part intake pipe 62b. The high temperature part intake pipe 62a is connected to a high temperature part intake 60c provided at the upper part of the tank 60 independently of the inflow port 60a. The intermediate temperature portion intake pipe 62b is connected to an intermediate temperature portion intake port 60d provided below the high temperature portion intake port 60c.

  The intake pipe 62 includes a switching valve 62c at the junction of the high temperature part intake pipe 62a and the intermediate temperature part intake pipe 62b, and the water intake source in the tank 60 is switched to the high temperature part intake port 60c or the intermediate temperature part intake port 60d.

  The water supply pipe 63 is used for supplying water to the tank 60. The water supply pipe 63 includes, for example, a branch water supply pipe 63 a that is connected to a water supply port 60 e provided in the lower part of the tank 60 independently of the outlet 60 b and branched in front of the tank 60.

  Furthermore, the hot water storage tank unit 54 includes a hot water mixing valve 64 that mixes the hot water I supplied from the intake pipe 62 and the water supplied from the branch water supply pipe 63a. The hot water supply mixing valve 64 is provided at the junction of the intake water pipe 62 and the branch water supply pipe 63a, and switches the mixing ratio of the hot water I supplied from the intake water pipe 62 and the water supplied from the branch water supply pipe 63a. The temperature of the hot water I supplied from 65 is adjusted. Normal temperature water can also be discharged.

  The hot water supply pipe 65 is connected to the shower 101a and the bathtub 101b of the bathroom 101 shown in FIG. 1, the faucet 102a of the washroom 102 and the faucet of the kitchen 103 (not shown), and supplies hot water I or water. In addition, a mist hot water supply pipe 65 a is connected to the hot water supply pipe 65 connected to the bathroom 101. The mist generator 2 is connected to the mist hot water supply pipe 65a branched here.

  Next, an operation example of the heat pump type hot water supply apparatus 4 will be described. In the hot water supply device 4, first, water is supplied from the water supply pipe 63 to the tank 60 of the hot water storage tank unit 54. The water supplied to the tank 60 is supplied to the water heat exchanger 56 of the heat pump unit 53 through the cold water pipe 61b.

  In the heat pump unit 53, the air is supplied to the air heat exchanger 55 by the fan 55a, heat exchange is performed with the refrigerant gas flowing through the refrigerant pipe 57, and the temperature of the refrigerant gas rises. The refrigerant gas that has been heat-exchanged by the air heat exchanger 55 is compressed by the compressor 58, so that the temperature further increases.

  Then, the refrigerant gas compressed by the compressor 58 and raised in temperature is supplied to the water heat exchanger 56. Thereby, in the water heat exchanger 56, heat exchange is performed between the refrigerant gas whose temperature has been increased by heat exchange and compression with the atmosphere and the water supplied from the hot water storage tank unit 54, and hot water I is generated. Is done. The refrigerant gas heat-exchanged by the water heat exchanger 56 is expanded by the expansion valve 59 to lower the temperature, and is supplied to the air heat exchanger 55 again.

  Moreover, the hot water I produced | generated by heat-exchange with the water heat exchanger 56 is returned to the tank 60 by the hot water piping 61a. As a result, the tank 60 stores hot water I and water in a state where the upper side has a high temperature and the lower side has a low temperature. The hot water I stored in the tank 60 is taken in by a water intake pipe 62. Here, when the temperature of the supplied water is high, the hot water I is taken from the high temperature portion intake pipe 62a, and when the temperature of the supplied water is low, the hot water I is taken from the intermediate temperature portion intake pipe 62b.

  The hot water I taken by the water intake pipe 62 is mixed with the water supplied from the branch water supply pipe 63b by the hot water supply mixing valve 64. The temperature of the hot water I supplied from the hot water supply pipe 65 is adjusted by switching the mixing ratio of the hot water I and water with the hot water supply mixing valve 64. Of course, room temperature water can also be sent to the hot water supply pipe 65. Hot water I or water supplied from the hot water supply pipe 65 is distributed to the bathroom 101, the washroom 102, and the kitchen 103. Thereby, the hot water I or water is supplied to the mist generating device 2 through the mist hot water supply pipe 65a branched from the hot water supply pipe 65. The hot water supply device 4 may not be a heat pump type using a natural refrigerant, or may be an ordinary electric water heater that is not a heat pump type, and may be a hot water supply device using a gas as a heat source or another heat source.

<Air conditioning remote control, mist remote control>

<Control system for bathroom air conditioner and mist generator>
FIG. 18 is a block diagram illustrating a configuration example of a control system of the bathroom air conditioner 3 and the mist generator 2.
The bathroom air conditioner 3 shown in FIG. 18 adjusts the temperature in the bathroom 101 from which water or hot water I is ejected by the mist generator 2 shown in FIG. The bathroom air conditioner 3 includes a control unit 5A having a CPU (Central Processing Unit) for controlling the temperature in the bathroom 101 based on temperature detection information obtained by detecting the temperature in the bathroom 101. The air conditioning remote controller 6 described above is connected to the control unit 5A of the bathroom air conditioner 3 via a communication cable 6a. In this example, the operation signal S6 is output from the air conditioning remote controller 6 to the control unit 5A via the communication cable 6a.

  A temperature detection sensor 69 as an example of temperature detection means is connected to the control unit 5A. The temperature detection sensor 69 is attached to the suction port 38 shown in FIG. 12 or 13 and outputs a temperature detection signal S69 obtained by detecting the temperature in the bathroom 101 to the control unit 5A. The controller 5A receives the temperature detection signal S69 from the temperature detection sensor 69, and executes temperature control based on the result of comparing the temperature detection information obtained by digitally processing the temperature detection signal S69 with the temperature setting information.

  For example, when the upper limit temperature T1 and the lower limit temperature T2 in the bathroom 101 are set, the control unit 5A outputs the drive voltage V33 to the heater 33 to heat the air in the bathroom 101 and the temperature in the bathroom 101. Is detected through the temperature detection sensor 69. The controller 5A stops the heating process when the temperature in the bathroom 101 reaches the upper limit temperature T1, and then detects the temperature in the bathroom 101 and performs the heating process when the temperature in the bathroom 101 reaches the lower limit temperature T2. Start.

  In this example, the control unit 5A measures the elapsed time from the time when the heat treatment is stopped to the time when the heat treatment is started, and thereafter performs the heat treatment of the air in the bathroom 101 based on the upper limit temperature T1 and the elapsed time. Execute. In this way, the comparison process between the lower limit temperature T2 and the temperature in the bathroom 101 can be omitted, and the load on the control unit 5A can be reduced.

  In addition, the control unit 5A corrects the previous elapsed time by measuring the elapsed time from the time when the previous heat treatment was stopped to the time when the heat treatment is started after the predetermined time has elapsed. If it does in this way, the heat processing of the air in the bathroom 101 based on upper limit temperature T1 and elapsed time can be performed now with high precision.

  The controller 5A is configured to control the temperature in the bathroom 101 by setting the operating temperature of the mist generating device 2 in three stages of “strong, medium, and weak” with respect to the upper limit temperature T1 in the bathroom 101. In this way, the temperature in the bathroom can be maintained at three levels of “strong, medium, and weak”.

  Of course, it is not limited to these temperature control methods, the upper limit temperature T3 and the lower limit temperature T4 in the bathroom 101 are set for the control unit 5A, and the temperature control is performed based on the upper limit temperature T3 and the lower limit temperature T4. You may make it do. In this case, the control unit 5 </ b> A outputs the drive voltage V <b> 33 to the heater 33 to heat the air in the bathroom 101 and detects the temperature in the bathroom 101 through the temperature detection sensor 69. When the temperature in the bathroom 101 reaches the upper limit temperature T3, the control unit 5A stops the heat treatment, detects the temperature in the bathroom 101 after a predetermined time, and compares the temperature in the bathroom 101 with the lower limit temperature T4. Then, heat treatment is executed based on the comparison result.

  For example, the control unit 5A starts the heat treatment when the temperature in the bathroom 101 becomes the lower limit temperature T4 or less, and refrains from the heat treatment when the temperature in the bathroom 101 exceeds the lower limit temperature T4. After a predetermined time has elapsed, the temperature in the bathroom 101 is detected, the temperature in the bathroom 101 is compared with the lower limit temperature T4, and the heat treatment is performed based on the comparison result.

  As described above, the human body detection sensor 69A attached to the front panel 26 of the bathroom air conditioner 3 is connected to the control unit 5A. A human body detection signal S69a is output from the human body detection sensor 69A to the control unit 5A.

  The control unit 5A is supplied with a signal S69b indicating whether or not this switch is turned on from the bathroom lighting switch 69B. The control unit 5A is supplied with drive voltages V36, V40c and V33 for operating the fan motor 36, damper motor 40c and heater unit 33, and a control signal S44 for controlling the operation of the ion generator 44. .

  A power supply unit 2B shown in FIG. 18 includes a power supply unit 2Ba, a solenoid valve drive unit 2Bb, and a control unit 2Bc having a CPU. The power supply unit 2Ba generates a DC voltage of 24V used for driving the solenoid valve, a DC voltage for driving the motors 73 and 84 of the nozzle unit 2, and the like from a household AC power source, for example, AC 100V.

  A solenoid valve drive unit 2Bb and a control unit 2Bc are connected to the power supply unit 2Ba, and a solenoid valve that constitutes the solenoid valve unit 2A using a DC voltage of 24V generated by the power supply unit 2Ba under the control of the control unit 2Bc. 2d, 2e, 2f are driven. In this case, the solenoid valves 2d, 2e, and 2f are opened by applying the drive voltages V2d, V2e, and V2f of DC24 [V], respectively. When the drive voltage V2d = 0 [V], the solenoid valve 2d is closed, when the drive voltage V2e = 0 [V], the solenoid valve 2e is closed, and when the drive voltage V2f = 0 [V] Each valve of the valve 2f is closed.

  As described above, the temperature detection sensor 2h attached to the electromagnetic valve unit 2A is connected to the control unit 2Bc. In this example, a temperature detection signal S2h is output from the temperature detection sensor 2h to the control unit 2Bc. The mist remote controller 7 described above is connected to the control unit 2Bc of the power supply unit 2B via a communication cable 7a. An operation signal S7a is output from the mist remote controller 7 to the control unit 2Bc via the communication cable 7a. The control unit 2Bc controls the operation of the electromagnetic valve driving unit 2Bb, and controls the directions of the nozzles 2m1, 2m2, and 2m3 of the nozzle unit 2 using a DC voltage generated by the power supply unit 2Ba.

  Further, the control unit 5A of the bathroom air conditioner 3 and the control unit 2Bc of the power supply unit 2B are connected to each other so that the bathroom air conditioner 3 and the mist generating device 2 can be linked. For example, the communication control signal S5a is output from the control unit 5A to the control unit 2Bc, and the mist operation is executed based on the content specified by the air conditioning remote controller 6. On the contrary, the communication control signal S5a may be output from the control unit 2Bc to the control unit 5A, and the air conditioning operation may be executed based on the contents designated by the mist remote controller 7.

FIG. 19 is a time chart showing an example of temperature detection based on the first temperature control of the bathroom 101.
In the temperature detection example shown in FIG. 19, the vertical axis is the set temperature Tx [° C.] of the bathroom 101. The horizontal axis represents the elapsed time tx [hr] after the heater unit 33 is turned on. The curve in the figure is a temperature detection curve I showing an example of a change in temperature in the bathroom. The temperature detection curve I is obtained by digitally processing the temperature detection signal S69 output from the temperature detection sensor 69.

  In this example, the upper limit temperature T1 during the mist sauna operation in the bathroom 101 is set, and the lower limit temperature T2 is set (T2 <T1). The upper limit temperature T1 is set as a temperature at which the heater section 33 is turned off (hereinafter referred to as heater off temperature), and the lower limit temperature T2 is set as a temperature at which the heater section 33 is turned on (hereinafter referred to as heater on temperature).

  In this example, when the heating operation (during mist spraying) is performed during bathing, the temperature in the bathroom 101 is always monitored by the temperature detection sensor 69, and when the heater off temperature T1 is reached, the drive voltage to the heater unit 33 is reached. V33 is turned off. Thereafter, the temperature in the bathroom 101 is continuously monitored, and the time t ′ until the temperature in the bathroom reaches the heater-on temperature T2 is measured. When the heater on temperature T2 is reached, the drive voltage V33 to the heater section 33 is turned on. The on / off control of the heater 33 is a first routine. The second and subsequent on / off control of the heater unit 33 is performed using the heater off temperature T1 and the subsequent elapsed time t.

  In this example, the first routine operation is executed and the time t is corrected every predetermined time. With respect to the upper limit temperature T1, three set temperatures of “strong, medium, and weak” are provided, and the mist sauna operating environment can be controlled in conjunction with the three-stage bathroom temperature. By changing the upper limit temperature and the blown-out air volume, the mist sauna operating environment may be made into three stages of strong, medium and weak. Further, the upper limit temperature T1 may be two steps of strong and weak, four steps, or other steps.

FIG. 20 is a time chart showing a temperature detection example based on the second temperature control of the bathroom 101.
In the temperature detection example shown in FIG. 20, the vertical axis is the set temperature Tx [° C.] of the bathroom 101. The horizontal axis represents the elapsed time tx [hr] after the heater unit 33 is turned on. The curve in the figure is a temperature detection curve II showing an example of a change in temperature in the bathroom. The temperature detection curve II is obtained by digitally processing the temperature detection signal S69 output from the temperature detection sensor 69.

  In this example, the upper limit temperature T3 during the mist sauna operation in the bathroom 101 is set, and the lower limit temperature T4 is set (T4 <T3). Similarly to the first temperature control example, the upper limit temperature T3 is set as the heater off temperature, and the lower limit temperature T4 is set as the heater on temperature. In this example, when a heating operation (during mist spraying) is performed during bathing, the temperature in the bathroom 101 is always monitored by the temperature detection sensor 69, and when the heater off temperature T3 is reached, the drive voltage to the heater unit 33 is reached. V33 is turned off. So far, it is the same as the first temperature control example.

  According to the second temperature control example, the temperature in the subsequent bathroom 101 is monitored intermittently. The temperature monitoring time for that is set. For example, the temperature in the bathroom 101 is detected again after a predetermined time (for example, 30 seconds) from the time when the temperature in the bathroom 101 reaches the heater-off temperature T3. If the temperature in the bathroom 101 exceeds the heater-on temperature T4 at this time, nothing is done. On the other hand, if the temperature in the bathroom 101 is lower than the heater on temperature T4 at this time, the drive voltage V33 to the heater unit 33 is turned on.

  Hereinafter, the process of detecting the temperature in the bathroom 101 is repeated again every time a predetermined time (for example, 30 seconds) elapses from the time when the temperature in the bathroom 101 reaches the heater-off temperature T3. The heater on temperature T4 is compared, and on / off control of the heater section 33 is executed based on the comparison result. Thereby, since the frequency | count of driving of the relay for control of the heater part 33 can be reduced, compared with the 1st temperature control example, it becomes possible to reduce relay power consumption.

  Subsequently, an operation example of the bathroom system 1 will be described. FIG.21 and FIG.22 is a flowchart which shows the operation example (the 1 and 2) at the time of mist sauna driving | operation (bath mist mode).

  In this embodiment, the mist generating device 2 and the bathroom air conditioner 3 are interlocked to construct a mist sauna system in the bathroom system 1. In this example, a heating operation is performed before bathing, or at the start of the mist operation, control is performed such as switching the bathroom air conditioner 3 from the heating “strong” operation to the “medium” operation according to the temperature in the bathroom. To get a comfortable mist sauna environment.

  In this example, when the bath mist button 7b is pushed by the mist remote controller 7 and the bath mist is turned on, or when the bath mist button 6b is pushed and the bath mist is turned on by the air conditioning remote controller 6, the bath mist mode is set. This mode of operation is started. When bathing mist is turned off or when a stop is instructed, the mist generating device 2 is drained after passing warm water I through the drain pipe 2c. Further, a case where the predetermined temperature T5 is, for example, 30 ° C. will be described as an example.

  The operation is started when the bathing mist is turned on under these operating conditions. In step ST22 of the flowchart shown in FIG. 21, the temperature detection sensor 69 of the bathroom air conditioner 3 detects the bathroom temperature, and the control unit 5A detects whether the bathroom temperature Tx exceeds the predetermined value 30 ° C. . When the bathroom temperature Tx exceeds the predetermined temperature T5 = 30 ° C., the process proceeds to step ST23, and the heating operation of the bathroom air conditioner 3 is set to “medium”. At this time, the values of the heater-off temperatures T1 and T3 to the heater unit 33 of the bathroom air conditioner 3 are lowered to set the temperature to be “medium” at a lower temperature than when the heating operation is “strong”.

  Moreover, the control voltage V36 to the fan motor 36 of the bathroom air conditioner 3 is dropped, and the fan 35 makes the rotation low. In this case, the damper 40 is fully closed, that is, the circulation position (see FIG. 14A). At this position, the circulation air passage 43a from the suction port 38 to the blower outlet 41 is formed in the fan portion 32, so that the air sucked from the suction port 38 passes through the circulation air passage 43a and is warmed by the heater portion 33. Then, the air is blown into the bathroom 101 from the air outlet 41 through the air outlet grill 46 of the front panel 26. Thereafter, the process proceeds to step ST25.

  When the bathroom temperature Tx is lower than the predetermined temperature T5, for example, 30 ° C., the process proceeds to step ST24 and the heating operation of the bathroom air conditioner 3 is set to “strong”. At this time, the heater off temperature to the heater unit 33 of the bathroom air conditioner 3, that is, the upper limit temperatures T <b> 1 and T <b> 3 are increased to set the temperature to be “strong” at a higher temperature than when the heating operation is “medium”. The

  Moreover, the control voltage V36 to the fan motor 36 of the bathroom air conditioner 3 is raised, and the fan 35 rotates at high speed. In this case, the damper 40 is fully closed, that is, the circulation position (see FIG. 14A). At this position, the circulation air passage 43a from the suction port 38 to the blower outlet 41 is formed in the fan portion 32, so that the air sucked from the suction port 38 passes through the circulation air passage 43a and is warmed by the heater portion 33. Then, the air is blown into the bathroom 101 from the air outlet 41 through the air outlet grill 46 of the front panel 26. Thereafter, the process proceeds to step ST25.

  Next, in step ST25, the nozzle unit 2C is controlled and rotated so that the nozzles 2m1, 2m2, and 2m3 face the bathtub 101b. At this time, the drive mechanism 71 or 81 shown in FIG. 8A or B operates to change the orientation of the nozzles 2m1, 2m2, and 2m3. As a result, mist is not applied to the person's head.

  Next, wastewater treatment is performed in step ST26. In this case, the solenoid valve 2d for hot water supply and the solenoid valve 2f for drainage are opened in the solenoid valve unit 2A (see FIG. 2). Hot water I supplied from the hot water supply apparatus 4 through the water supply pipe 2a is supplied to the drain pipe 2c via the electromagnetic valve 2d and the electromagnetic valve 2f (see FIGS. 1 and 2).

  Next, in step ST27, based on the detection output of the temperature detection sensor 2h disposed in the electromagnetic valve unit 2A, the temperature of the hot water I supplied to the electromagnetic valve unit 2A via the water supply pipe 2a is equal to or higher than a predetermined value. For example, it is determined whether or not the angle is 35 ° or more. After the temperature becomes equal to or higher than the predetermined value, the process proceeds to step ST28.

  In step ST28, mist generation processing is performed. As described above, the mist generation process is performed after the temperature of the hot water I supplied to the electromagnetic valve unit 2A becomes equal to or higher than a predetermined value. You can avoid it.

  In this case, in the electromagnetic valve unit 2A, the electromagnetic valve 2f is closed, and the electromagnetic valve 2e for the nozzle unit is opened. At this time, the hot water I supplied from the hot water supply device 4 through the water supply pipe 2a is supplied to the nozzle pipe 2b via the electromagnetic valve 2d and the electromagnetic valve 2e (see FIGS. 1 to 3A).

  Next, in step ST29, it is determined whether or not the bath mist button 7b or 6b has been pressed to turn off the bath mist, or the operation stop button 7d has been pressed to instruct a stop. When bathing mist is turned off or a stop is instructed, the process proceeds to step ST30. In step ST30, the operation of the bathroom air conditioner 3 is stopped. That is, energization to the heater unit 33 and the fan motor 36 of the bathroom air conditioner 3 is stopped.

  Then, in step ST31, the electromagnetic valve 2f for drainage is opened, drainage control is executed, and drainage processing is performed. At this time, in the electromagnetic valve unit 2A, the electromagnetic valve 2e for mist is closed while the electromagnetic valve 2d for hot water supply is opened (see FIG. 3B). The reason why the electromagnetic valve 2f for drainage is opened first and then the electromagnetic valve 2e for mist is closed after that is to prevent a knocking phenomenon in which pipes generate sound due to a sudden change in water pressure. Thereby, the hot water I is filled in the drain pipe 2c. Then, in step ST32, it is determined whether or not a predetermined time, for example, t = 2 seconds, necessary for the treatment of the hot water I flowing into the drain pipe 2c has elapsed. When the predetermined time has elapsed, the process proceeds to step ST33.

  In step ST33, the hot water solenoid valve 2d is closed and the mist solenoid valve 2e is opened (see FIG. 4A). Thereby, the hot water I remaining in the nozzle pipe 2b is drained to the drain pipe 2c through the electromagnetic valves 2e and 2f. At this time, since the electromagnetic valve 2e remains open, the air III is taken into the electromagnetic valve 2e and the pipes 2j and 2k through the connection pipe 2b '. Thereby, the residual water (warm water) II in the connection pipe 2b ′, the electromagnetic valve 2e, the pipe 2j and 2k can be discharged to the outside of the bathroom through the electromagnetic valve 2f. (See FIGS. 1 and 4A).

  Then, in step ST34, it is determined whether or not a predetermined time required for the draining process, for example, t = 3 seconds has elapsed. When the predetermined time has elapsed, the process proceeds to step ST35. In step ST35, stop processing is performed. In this case, in the electromagnetic valve unit 2A, the electromagnetic valve 2e and the electromagnetic valve 2f are closed (see FIG. 4B). At this time, the nozzle unit 2C is also controlled, and the directions of the nozzles 2m1, 2m2, and 2m3 are returned to the home position HP. With this stop process, a series of operations in the bathing mist mode is completed.

  Step ST25 may not be provided. Further, the nozzles 2m1, 2m2, and 2m3 may be directed to the washing area 101e so that the mist may be applied to the human body. Further, the air conditioning remote controller 6 and the mist remote controller 7 are provided with operation buttons (not shown), and the nozzles 2m1, 2m1, A direction of 2m2 and 2m3 may be selected. The rotation control of the nozzle unit 2C in step ST25 may not be performed.

  Thus, according to the bathroom system 1 as an embodiment of the present invention, the power supply unit 2B and the control unit 5A are provided, and the temperature in the bathroom 101 is detected by the temperature detection sensor 69 and is higher than a predetermined temperature. Control which distinguishes heating operation by the case and the case where it is low is made.

  In the above-described example, when the temperature in the bathroom is high due to the temperature of the temperature detection sensor 69 of the bathroom air conditioner 3 at the start of the mist operation, the heating operation of the bathroom air conditioner 3 is set to “medium”. Let the amount of warm air blown to be “medium” and the heater off temperatures (upper limit temperatures) T1 and T3 be “medium” temperatures (values lower than high).

  When the temperature in the bathroom is low, the amount of warm air blown into the bathroom is set to “large” so that the heating operation becomes “strong”, and the heater off temperatures (upper limit temperatures) T1 and T3 are set to “strong” temperatures. (High value). Thereby, the hot water sprayed from the nozzle unit 2C by changing the heater-off temperature (upper limit temperature) T1, T3, the amount of hot air, etc. of the bathroom air conditioner 3 according to the temperature (state) of the bathroom 101 at the start of the mist operation. Even if the temperature of I is not directly controlled, a comfortable mist environment suitable for the temperature state in the bathroom at that time can be provided.

  In addition to the control of the bathroom air conditioner 3 described above, the temperature of the hot water I ejected from the nozzle unit 2C may be controlled, and in this case, the temperature control in the bathroom can be performed more finely. As for “strong / medium / weak” in the heating operation state, the amount of heat generated by the heater section 33 is changed in accordance with the heating state “strong / medium / weak” instead of the heater off temperature (upper limit temperature) T1, T3. The heating voltage may be varied by controlling the drive voltage V33 so as to be “strong / medium / weak”. Therefore, a comfortable mist driving environment can be provided by performing heating control with the bathroom air conditioner 3 on the temperature in the bathroom before bathing during the mist driving.

  The present invention is extremely suitable when applied to a bathroom unit (unit bath) that ejects hot water or water supplied from a hot water supply apparatus.
