As shown in FIG. 1, the mist section 90 includes a main body casing 91 a installed on the back side of the ceiling Yc of the bathroom Y, and a grill plate 91 b installed on the front side of the ceiling Yc of the bathroom Y. The mist section 90 includes various members that perform spraying of mist water into the bathroom Y, heating operation in the bathroom Y, and the like in a housing formed of the main body casing 91a and the grill plate 91b.

  As shown in FIGS. 1 and 2, the mist portion 90 includes the nozzle unit 2 supported by a flat support plate 28 formed integrally with the grill plate 91b. The nozzle unit 2 has a plurality of nozzle portions 21 as spraying means for spraying mist water into the bathroom Y. Therefore, the plurality of nozzle portions 21 included in the nozzle unit 2 are supported on the ceiling Yc by the support plate 28. The plurality of nozzle portions 21 are provided, for example, in a state where the tips protrude from the support plate 28 on the ceiling Yc side into the bathroom Y.

  More specifically, in the present embodiment, the nozzle unit 2 including the plurality of nozzle portions 21 protrudes from the ceiling Yc, for example, in the vicinity of the boundary between the bathtub space Ya and the washing space Yb as shown in FIG. It is provided as follows. And the nozzle part 21 has the front-end | tip inclined and protruded toward the washing space Yb from the ceiling Yc between bathtub space Ya and the washing space Yb. That is, the mist water spraying direction from the nozzle portion 21 is a direction from the space between the bathtub space Ya and the washing space Yb toward the washing space Yb.

A nozzle supply path 3 to be described later is connected to the nozzle unit 2, and hot water heated by a first combustor 42 to be described later of the heat source machine 1 is supplied to the nozzle supply path 3 through a hot water path 82. Thus, a mist operation is performed in which warm water, which is mist water, is sprayed as mist from the nozzle portion 21 of the nozzle unit 2 into the bathroom Y.
When spraying, the nozzle part 21 sprays mist water with the pressure of mist water. That is, the nozzle part 21 is a so-called one-fluid nozzle.

  The plurality of nozzle portions 21 are arranged as shown in FIG. 2, for example.

Therefore, in the initial operation, the direction in which the staying water is sprayed from the nozzle portion 21 is the direction from the space between the bathtub space Ya and the washing space Yb toward the washing space Yb. Here, for example, as shown in FIG. 1, water is sprayed from the nozzle portion 21 with a spray range φa1 (spray range represented by the angle range φa1).

  In FIG. 1, the change movable louver 97 is provided adjacent to the nozzle unit 2 on the washing space Yb side with respect to the nozzle unit 2. Further, the change movable louver 97 is inclined in a direction opposite to the nozzle portion 21 so as to form a louver angle θa1 with the ceiling Yc. The louver angle θa1 is, for example, an angle smaller than at least 90 °, and the change movable louver 97 is inclined in a direction that does not obstruct the spray range φa1 of the accumulated water sprayed from the nozzle portion 21. The inclination direction of the change movable louver 97 can also be referred to as a direction along the direction of staying water spray, for example.

  In such a relationship between the stay water spray range φa1 from the nozzle portion 21 and the inclination direction of the changeable movable louver 97 in FIG. 1, in the initial operation, the stay water has the spray range φa1 and the washing space Yb. Sprayed on. In this case, if a user is present in the spray range φa1 in the washing space Yb, the user is charged with stagnant water. Therefore, cold stagnant water is applied to the user, and the user is uncomfortable. Moreover, when bacteria etc. are generated in the staying water, the health of the user is hindered.

  Therefore, as shown in FIG. 4, the mist control unit 13 rotates the change movable louver 97 based on the position of the user in the bathroom Y acquired by the human detection unit 101. At this time, the mist control unit 13 considers the position of the user and changes the movable movable louver 97 so as to block at least a part of the spray range φa1 (see FIG. 1) of the accumulated water sprayed from the nozzle unit 21. Rotate. That is, the mist control unit 13 rotates the changeable movable louver 97 so as to prevent the staying water from spraying on the user's location.

  In FIG. 4, the change movable louver 97 is inclined in the direction opposite to the nozzle portion 21 so as to form the louver angle θa2 with the ceiling Yc. The louver angle θa2 is, for example, an angle larger than at least 90 °, and the changeable louver 97 is inclined in a direction to block at least a part of the spray range φa1 (see FIG. 1) from the nozzle portion 21 of the accumulated water. Yes. The inclination direction of the change movable louver 97 can also be referred to as a direction intersecting with the direction of staying water spray, for example.

  Note that the range in which the louver angle can be changed when discharging stagnant water can be set larger than the range in which the louver angle can be changed during normal mist spraying. For example, the louver angle at the time of normal mist spraying can be changed from about 20 ° to about 90 °, while the louver angle when discharging stagnant water can be changed from about 10 ° to about 170 °. Has been.

  More specifically, as shown in FIG. 4, the change movable louver 97 is configured to have a size capable of covering at least a part of the nozzle portion 21 when rotated to the nozzle unit 2 side. Yes. As a result, the spray of accumulated water from the nozzle portion 21 toward the washing space Yb is partially blocked by the changeable movable louver 97. As a result, as shown in FIG. 4, in the initial operation, the staying water is sprayed on the washing space Yb having the spray range φa2. As described above, the stay water spray range is reduced from the spray range φa1 of FIG. 1 to the spray range φa2 of FIG. 4, so that it is possible to suppress the stay water from being applied to the users existing in the washing space Yb. In this case, for example, the angle of the changeable louver 97 is changed so that the spraying range of the staying water is deviated by about 30 to 40 ° with respect to the position where the user is present.

The mist control unit 13 may stop the operation of the circulation fan 94 when the changeable movable louver 97 is rotated as shown in FIG. In the case of FIG. 4, the mist control unit 13 stops the operation of the circulation fan 94. Thereby, it is possible to suppress the stagnant water sprayed in the initial operation from being diffused by the wind from the circulation fan 94.
Conversely, in FIG. 4, the mist control unit 13 may drive the circulation fan 94 to blow out air along the inclination of the changeable louver 97 through the air passage 93. Such an example will be described with reference to FIG.

  As shown in FIG. 5, the mist control unit 13 rotates the change movable louver 97 based on the position of the user in the bathroom Y acquired by the human detection unit 101. In FIG. 5, the change movable louver 97 is inclined in the direction opposite to the nozzle portion 21 so as to form a louver angle θa3 with the ceiling Yc. The louver angle θa3 is, for example, an angle larger than at least 90 °, and the change movable louver 97 is in a direction that blocks at least part of the spray range φa1 (see FIG. 1) of the accumulated water sprayed from the nozzle portion 21. Inclined. In this state, the mist control unit 13 drives the circulation fan 94 to blow out air along the inclination of the changeable louver 97 through the air blowing path 93.

Thereby, the spray of stagnant water from the nozzle part 21 to the washing room space Yb side is partially blocked by the changeable movable louver 97 and flows to the bathtub space Ya side. As a result, as shown in FIG. 5, in the initial operation, at least a part of the staying water having the spray range φa3 is sprayed to the bathtub space Ya side. Therefore, it is possible to suppress the staying water from being applied to the user existing in the washing space Yb.
As described above, when the circulation fan 94 is driven, the stagnant water is caused to flow toward the bathtub space Ya by the blowing of air from the air passage 93. Therefore, louver angle θa3 shown in FIG. 5 may be smaller than louver angle θa2 shown in FIG.

(6-2) Table for spray control of staying water In this embodiment, in order for the mist control unit 13 to perform the spray control of staying water as described above, the storage unit 14 controls the spraying of staying water. The table is remembered. This table will be described below with reference to FIGS.

  In FIG. 6A, it is assumed that the change movable louver 97 is inclined toward the washing space Yb when the user's location is the region α1. The region α1 is, for example, the wash space Yb side farthest from the bathtub 66. In this case, the change movable louver 97 does not block the stay water spray range β1a, and the staying water is sprayed to the user located in the region α1. In order to prevent the accumulated water from spraying to the user, the changeable louver 97 is controlled to the louver angle θα1 in FIG. 6B. Then, the retained water is sprayed by being limited to the spray range β1b by the changeable movable louver 97 having the louver angle θα1. Accordingly, the region α1 where the user exists is located outside the spray range β1b, and the user is not covered with the accumulated water.

  At this time, the louver angle of the changeable louver 97 is set so that at least the staying water sprayed in the vicinity of the region α1 where the user is present in the staying water spray range β1b does not enter the region α1. Is set. By such setting, it is possible to suppress the stagnant water in the piping or the like from being applied to a person in the bathroom in the initial operation.

  Next, in FIG. 7A, the user's location is the region α2, and the louver angle and spray range β1a of the changeable movable louver 97 are the same as those in FIG. The region α2 is, for example, the central portion of the washing space Yb. In this case, the change movable louver 97 does not block the stay water spray range β1a, and the staying water is sprayed to the user located in the region α2. In order to prevent the accumulated water from spraying to the user, the changeable louver 97 is controlled to the louver angle θα2 in FIG. 7B. Then, the retained water is sprayed by being limited to the spray range β1c by the changeable movable louver 97 having the louver angle θα2. Therefore, the region α2 where the user exists is located outside the spray range β1c, and the user is not covered with the accumulated water. The method for setting the louver angle is the same as in FIG.

  In FIG. 8A, the user's location is the region α3, and the louver angle and spray range β1a of the changeable movable louver 97 are the same as those in FIG. For example, the region α3 is closest to the bathtub 66 in the washing space Yb. In this case, the change movable louver 97 does not block the stay water spray range β1a, and the staying water is sprayed to the user located in the region α3. In FIG. 8B, the changeable movable louver 97 is controlled to the louver angle θα3 and the circulation fan 94 is driven at, for example, the air flow level 2 in order to prevent the accumulated water from spraying on the user. The changeable louver 97 having the louver angle θα3 and the wind of the air volume level 2 toward the bathtub space Ya side cause the staying water to be sprayed while being limited to the spray range β1d on the bathtub space Ya side. Therefore, the region α3 where the user exists is located outside the spray range β1d, and the user is not covered with the accumulated water. The method for setting the louver angle is the same as in FIG.

  FIG. 9 shows the relationship between the position of the user, the louver angle, and the air volume level of the wind from the circulation fan when spray control is performed so that the user who is present in the bathroom Y does not get accumulated water in the initial operation. An example of a table in which is defined is shown. The table of FIG. 9 is not limited to this, but is defined based on, for example, FIGS. 6 to 8. For example, based on FIG. The louver angle θα1 of the change movable louver 97 and the air volume level 0 are stored in one record. In the table of FIG. 9, the amount of accumulated water sprayed from the nozzle unit 21 may be further defined.

(6-3) Flow of Residual Water Spray Control Next, the flow of the retained water spray control in the initial operation performed by the control unit 11 will be described with reference to FIG.
Step S10: When the accepting unit 19 accepts the start of the mist operation from the user (Yes in Step S10), the heat source control unit 16 controls the operation of the heat source unit 1 and generates heated mist water. In addition to the start of the mist operation, the reception unit 19 includes the amount of mist sprayed in the mist operation, the temperature of the mist, the heating temperature of the air in the heat exchanger 95 for air heating, and the direction of the changeable louver 97 Settings may be received from the user.
In addition, the mist control unit 13 instructs the person detection unit 101 to acquire the position of the user in the bathroom Y in the initial operation immediately after starting the mist operation.
When the reception unit 19 has not received the start of the mist operation (No in step S10), the reception unit 19 waits until the mist operation is input.

Step S11: The person detection unit 101 detects the presence or absence of a user in the bathroom Y. If a user exists in the bathroom Y (Yes in step S11), the process proceeds to step S12.
On the other hand, when there is no user in the bathroom Y (No in step S11), the mist control unit 13 ends the stay water spray control. In this case, the mist control unit 13 performs control of the louver angle of the changeable movable louver 97, control of the spray amount, control of the circulation fan 94, and the like related to spray control for preventing the accumulated water from splashing on the user. Not performed. For example, the mist control unit 13 sprays the accumulated water from the nozzle unit 21 based on the louver angle of the changeable movable louver 97 received by the receiving unit 19, the spray amount, the air volume from the circulation fan 94, and the like. Since the user does not exist in the bathroom Y, the accumulated water is not applied to the user.

Step S <b> 12: The person detection unit 101 acquires the presence position of the user in the bathroom Y and outputs it to the mist control unit 13.
In addition, you may perform the process of step S11 and S12 integrally. For example, when the person detection unit 101 acquires the location of the user in the bathroom Y, the person detection unit 101 outputs it to the mist control unit 13. And when the person detection part 101 cannot acquire the presence position of the user in the bathroom Y, the mist control part 13 complete | finishes the spray control of stagnant water.

Step S13: In the initial operation, the mist control unit 13 controls the change movable louver 97 based on the position of the user in the bathroom Y acquired by the person detection unit 101. At this time, the mist control unit 13 controls the changeable louver 97 with reference to the table illustrated in FIG. 9 stored in the storage unit 14.
For example, when the mist control unit 13 acquires α2 as the position of the user in the bathroom Y, the mist control unit 13 refers to the table of FIG. 9 and controls the change movable louver 97 to the louver angle θα2.
Further, the mist control unit 13 may drive the circulation fan 94 in addition to controlling the louver angle of the change movable louver 97. Thereby, air is blown out from the air blowing path 93 along the change movable louver 97 in which the louver angle is controlled.

Step S <b> 14: The mist control unit 13 sprays the accumulated water from the nozzle unit 21 after controlling the change movable louver 97. In step S13, the change movable louver 97 is controlled to a louver angle at which the accumulated water is not applied to the user, so that it is suppressed that the accumulated water is applied to the user existing in the bathroom Y in the initial operation.
When the mist control unit 13 controls to change the movable movable louver 97 so as to blow air from the circulation fan 94, the direction of staying water spray is further away from the user existing in the bathroom Y. Therefore, it is possible to further suppress the user from staying with water during the initial operation.

  Here, the mist control unit 13 may adjust the amount of staying water sprayed from the nozzle unit 21 to any one within the upper limit range from the maximum vicinity to the maximum. For example, the amount of staying water sprayed can be adjusted within the range of 80% to 100% of the maximum sprayed amount. The mist control unit 13 can control the amount of staying water sprayed by controlling the opening of the spray flow rate control valve 10. By increasing the amount of staying water sprayed in this way, it is possible to expedite discharge of staying water from the nozzle portion 21 in the pipe or the like. Therefore, the mist user can use the mist warmed in the mist apparatus 100 at an early stage.

  Step S15: The mist control unit 13 acquires the temperature of the mist water from the temperature sensor 88, and when the temperature of the mist water becomes equal to or higher than a predetermined value (Yes in Step S15), the process proceeds to Step S16. On the other hand, when the temperature of the mist water is less than the predetermined value (No in step S15), the mist control unit 13 waits until the temperature of the mist water becomes equal to or higher than the predetermined value, and continues the spraying of the staying water. The predetermined value is a temperature at which a mist user feels comfortable, for example, 28 ° C.

  Here, when the temperature of the water for mist becomes a predetermined value or more, the mist control unit 13 may output that fact to the notification unit 15. And the alerting | reporting part 15 may alert | report a user that the temperature of the water for mist became more than predetermined value via a speaker (not shown) and a display apparatus (not shown). As described above, since the user is notified when the temperature of the mist becomes a predetermined value or more, the user can grasp that the discharge of the accumulated water is finished and the mist can be comfortably used.

Step S16: When the temperature of the mist reaches a predetermined value or more, the mist control unit 13 controls the change movable louver 97 based on the setting of the louver angle of the change movable louver 97 when the reception unit 19 accepts the setting. Thereby, a mist can be provided to a user at a desired louver angle.
In addition, when the reception unit 19 receives the mist spray amount in the mist operation, the temperature of the mist, the heating temperature of the air in the heat exchanger 95 for air heating, etc., the mist control unit 13 Take control. Thereby, a mist can be provided to a user with desired spraying amount, temperature, and air temperature.

  Step S17: When the operation time of the mist operation is set, the mist control unit 13 determines whether or not the set time has elapsed from the start of the mist operation. If the set time has elapsed since the start of the mist operation (Yes in step S17), the mist control unit 13 ends the mist operation. Otherwise (No in step S17), the mist control unit 13 continues the mist operation.

  According to the present embodiment, in the initial operation immediately after the start of the mist operation, the mist control unit 13 controls the louver angle of the changeable louver 97 so as to prevent the mist from spraying to the user's location. To do. Therefore, it is possible to suppress the unheated cold stagnant water staying in the pipe or the like from being applied to a person in the bathroom Y, and to suppress discomfort felt by the user of the mist. In addition, it is possible to suppress the accumulated water in which bacteria or the like may be generated from being applied to the user.
