<Operation example of bathroom air conditioning system 1>
Next, an operation example of the mist operation of the bathroom air conditioning system 1 will be described. Here, the mist operation is an example of a mist mode. When the bathroom air-conditioning system 1 performs mist operation, warm air is blown into the bathroom 101 from the outlet 41 of the bathroom air-conditioning apparatus 3, and mist from the hot water is generated in the bathroom 101 from the mist ejection unit 2 </ b> C of the mist generating apparatus 2. Erupted. Thereby, a mist sauna environment is created in the bathroom 101.

  Hereinafter, the start of the mist operation will be described. FIGS. 17-20 is a flowchart which shows the operation example at the time of the mist driving | operation start of the bathroom air conditioning system 1 provided with mist generator 2A1 or mist generator 2E. FIG. 21 is an explanatory diagram showing an operation example at the start of the mist operation of the bathroom air-conditioning system 1 of the present invention. FIG. 21A shows the time change of the temperature at the start of the mist operation, and FIG. 21B shows the time change of the humidity at the start of the mist operation. In FIG. 21, F shows the time change by the bathroom air-conditioning system 1 of this invention. A time change when only normal mist having a normal particle diameter is ejected is indicated by G, and a time change when only fine mist is ejected is indicated by H.

  In the bathroom air conditioning system 1, the mist operation is started with the following flow. In a state where the mist generator 2 and the bathroom air conditioner 3 are stopped, the user first presses the mist button 7b of the mist remote controller 7 or the heating mode button 6e of the air conditioner remote controller 6 (step ST01 in FIG. 17). Thereby, the mist LED 6k of the air-conditioning remote controller 6 and the mist LED 7f of the mist remote controller 7 blink (step ST02).

  Thereafter, “strong” of the heating mode LED 6l of the air-conditioning remote controller 6 and “strong” of the heating mode LED 7g of the mist remote controller 7 are turned on, and the bathroom air-conditioning apparatus 3 performs heating operation with the output of the heater unit 33 set to “strong”. Is started (step ST03). At this time, in the graph of the time change of FIG. 21, it is a part shown by I of FIG. 21A, and M of FIG. 21B. By starting the heating operation, the temperature in the bathroom 101 increases as shown in FIG. 21A, and the relative humidity in the bathroom 101 decreases as shown in FIG. 21B.

  Thereafter, a “mist operation start command” is transmitted from the mist remote controller 7 to the main controller 5A of the bathroom air conditioner 3 via the mist controller 2Bc of the mist generator 2 (step 04). In response to this “mist operation start command”, the main controller 5A of the bathroom air conditioner 3 detects the temperature in the bathroom by the temperature detection sensor 69, and the temperature in the bathroom is equal to or higher than a predetermined temperature (for example, 30 ° C.). Is determined (step ST05). Here, when the temperature in the bathroom is lower than the predetermined temperature, a “mist operation disable command” is transmitted from the main control unit 5A of the bathroom air conditioner 3 to the mist remote controller 7 (step ST06). After that, it waits for a predetermined time (for example, 5 seconds) (step ST07), and again from the mist remote controller 7 to the main control unit 5A of the bathroom air conditioner 3 via the mist control unit 2Bc of the mist generating device 2, the “mist operation start command”. "Is transmitted (step 04).

  If it is determined in step ST05 that the temperature in the bathroom is equal to or higher than the predetermined temperature, the main controller 5A of the bathroom air conditioner 3 transmits a “mist operation permission command” to the mist remote controller 7 (step ST08). . Thereafter, the system waits for a predetermined time (for example, 4 seconds) (step ST09), and the mist LED 6k and the mist LED 7f of the air-conditioning remote controller 6 remain blinking (step ST10).

  Thereafter, the mist control unit 2Bc uses the solenoid valve drive unit 2Bb to open the hot water solenoid valves 2d1 and 2d2 (step ST11) and open the drain solenoid valves 2f1 and 2f2 (step ST12). Thereby, it will be in the state from which the hot water I was drained from the drain piping 2c via the piping 2k from the water supply piping 2a.

  Thereafter, the timer t3 is reset by the mist control unit 2Bc of the mist generator 2 (step ST13 in FIG. 18), and whether or not the hot water I is equal to or higher than a predetermined temperature (for example, 30 ° C.) by the temperature detection sensors 2h1 and 2h2. Is discriminated (step ST14). When the temperature of the hot water I is lower than the predetermined temperature, it is determined whether or not a predetermined time (for example, 5 minutes) has elapsed since the reset of the timer t3 (step ST15).

  Here, when a predetermined time (for example, 5 minutes) or more has elapsed since the reset of the timer t3, it is determined that a failure has occurred in the hot water supply device 4 and the like, and the flow shown in FIG. 20 is executed. First, the error LED 7h of the mist remote controller 7 is turned on (step ST39 in FIG. 20). Thereafter, the mist control unit 2Bc closes the hot water supply electromagnetic valve 2d1 (2d2) by the electromagnetic valve drive unit 2Bb (step ST40) and opens the mist electromagnetic valve 2e1 (2e2) (step ST41). As a result, the residual water from the connection pipe 2b 'reaches the electromagnetic valve 2f through the pipes 2j and 2k and is drained to the drain pipe 2c. Thereby, the residual water in connection pipe 2b ', electromagnetic valve 2e, piping 2j, and 2k can be discharged outside the bathroom through electromagnetic valve 2f.

  After that, the system waits for a predetermined time (for example, 3 seconds) (step ST42), and the mist control unit 2Bc closes the mist electromagnetic valve 2e1 (2e2) by the electromagnetic valve drive unit 2Bb (step ST43), and discharges the electromagnetic valve 2f1 ( 2f2) is closed (step ST44). Thereafter, after the buzzer of the mist remote controller 7 is sounded for 3 seconds (step ST45), the heating operation of the bathroom air conditioner 3 and the louver 44 are stopped (step ST46).

  Here, when the user presses the stop button 7e of the mist remote controller 7 or the stop button 6h of the air conditioning remote controller 6, the error state is canceled (step ST47), and the error LED 7h of the mist remote controller 7 is turned off (step ST48). .

  Returning to FIG. 18, when it is determined in step ST15 that the predetermined time (for example, 5 minutes) or more has not elapsed since the reset of the timer t3 and the warm water I is determined to be the predetermined temperature (for example, 30 ° C.) or more in step ST14 The following flow is executed. It is determined whether or not a predetermined time (for example, 5 seconds) has elapsed since the reset of the timer t3 (step ST16). If a predetermined time (for example, 5 seconds) or more has not elapsed since the reset of the timer t3, the timer t3 is reset again (step ST17) and waits for a predetermined time (for example, 5 seconds) (step ST18).

  In step ST16, when it is determined that a predetermined time (for example, 5 seconds) or more has elapsed since the reset of the timer t3, or after waiting for a predetermined time (for example, 5 seconds) in step ST18, the mist LED 6k remains blinking. The mist LED 7f is turned on (step ST19), and the buzzer of the mist remote controller 7 is sounded for 1 second (step ST20).

  Thereafter, although not shown in the flowchart, when the nozzle unit 2G is provided, the propeller fan 2s is rotated by the fan motor 2r. The mist control unit 2Bc opens the mist solenoid valve 2e2 by the solenoid valve drive unit 2Bb (step ST21) and closes the drainage solenoid valve 2f2 (step ST22). Accordingly, a mist operation in which fine mist is jetted into the bathroom 101 from the nozzle unit 2C2 (or nozzle unit 2G) of the mist generating apparatus 2 and hot air is blown into the bathroom 101 from the outlet 41 of the bathroom air conditioner 3 (This state is an example of the first state). At this time, in the time change shown in FIG. 21, it is a location shown by J in FIG. 21A and N in FIG. 21B.

  In the bathroom air-conditioning system 1 of the present invention, since the fine mist is first ejected into the bathroom 101 as described above, as shown in F of FIG. 21A, compared with G in the case where normal mist is ejected. It becomes possible to prevent a rapid decrease in temperature.

  After the start of fine mist ejection, the apparatus waits for a predetermined time (for example, 5 minutes) (step ST23). Thereafter, the main control unit 5A determines whether or not the temperature in the bathroom 101 has become equal to or higher than a predetermined value (for example, 35 ° C.) by the temperature detection sensor 69 (step ST24). When the temperature in the bathroom 101 is not equal to or higher than a predetermined value (for example, 35 ° C.), the process waits until the temperature in the bathroom 101 becomes equal to or higher than the predetermined value.

  Here, in step ST23 and step ST24, after waiting for a predetermined time (for example, 5 minutes) after the start of ejection of the fine mist, it is determined whether or not the temperature in the bathroom 101 has become a predetermined value (for example, 35 ° C.) or more. did.

  After a predetermined time (for example, 5 minutes) has elapsed after the fine mist has been ejected and the temperature in the bathroom 101 has reached a predetermined value (for example, 35 ° C.), the humidity in the bathroom 101 is in a state of a predetermined value or more. After judging and lighting the mist LED 6k, the electromagnetic valve 2e1 for mist is opened (step ST25), and the electromagnetic valve 2f1 for draining is closed (step ST26). Thereby, it will be in the state by which normal mist was ejected in the bathroom 101 (this state is an example of a 2nd state). At this time, the time change shown in FIG. 21 is a portion indicated by K in FIG. 21A and O in FIG. 21B.

  Thus, in the bathroom air-conditioning system 1 of the present invention, the humidity in the bathroom 101 is a predetermined value in a state where the temperature in the bathroom 101 is equal to or higher than a predetermined value and the fine mist is jetted into the bathroom 101 and a predetermined time has elapsed. Judging that it is the above, the mist is normally ejected in the bathroom 101. Thereby, as shown to F of FIG. 21B, it becomes possible to raise the humidity in the bathroom 101 early compared with the case where only fine mist is ejected.

  Further, in the above-described example, a predetermined time (for example, 5 minutes) has passed since the fine mist ejection, and the interior of the bathroom 101 is at a predetermined temperature (for example, 35 ° C.), so that the interior of the bathroom 101 is at or above a predetermined humidity. I decided that. However, the humidity detection sensor 69a may determine whether or not the inside of the bathroom 101 is equal to or higher than the humidity of the humidity. The values of both the humidity detection sensor 69a and the temperature detection sensor 69 are detected, and the temperature in the bathroom 101 is detected. It may be discriminated by both values of humidity and humidity.

  After the normal mist injection is started, the drain solenoid valve 2f2 is opened (step ST27), the mist solenoid valve 2e2 is closed (step ST28), and the hot water solenoid valve 2d2 is closed (step ST29). ). Thereby, the ejection of fine mist into the bathroom 101 stops. Thereafter, although not shown in the flowchart, when the nozzle unit 2G is provided, the fan motor 2r is stopped and the propeller fan 2s is stopped.

  After step ST29, it waits for a predetermined time (for example, 10 minutes) (step ST30). Thereafter, the main control unit 5A determines whether or not the humidity in the bathroom 101 has reached a predetermined value (for example, 95%) or more using the humidity detection sensor 69a (step ST31). When the humidity in the bathroom 101 is not a predetermined value (for example, 95%) or higher, the process waits until the humidity in the bathroom 101 becomes a predetermined value (for example, 95%) or higher.

  When the humidity in the bathroom 101 exceeds a predetermined value, the mist LED 6k of the air conditioning remote controller 6 and the mist LED 7f of the mist remote controller 7 are turned on (step ST32). Thereafter, the hot water solenoid valve 2d2 is opened (step ST33), the mist solenoid valve 2e2 is opened (step ST34), and the drain solenoid valve 2f2 is closed (step ST35). Thereafter, the drain solenoid valve 2f1 is opened (step ST36), the mist solenoid valve 2e1 is closed (step ST37), and the hot water solenoid valve 2d1 is closed (step ST38). Thereby, the ejection of the normal mist into the bathroom 101 is stopped, and the ejection of the fine mist is started. At this time, in the time change shown in FIG. 21, it is a location shown by L in FIG. 21A and P in FIG. 21B.

  Thereafter, the operation of the mist generator 2 and the bathroom air conditioner 3 is stopped depending on whether the stop buttons 6h and 7e of the air conditioner remote controller 6 and the mist remote controller 7 are pressed or a predetermined time (for example, 1 hour) elapses. Further, the humidity detection sensor 69a continuously monitors the temperature in the bathroom 101. When the humidity in the bathroom 101 falls below a predetermined humidity (for example, 90%), a normal mist is ejected from the nozzle unit, and then again. When the humidity in the bathroom 101 exceeds a predetermined humidity (for example, 95%), the fine mist is ejected from the nozzle unit so that the normal mist and the fine mist are ejected according to the humidity in the bathroom 101. It may be.

  Thus, in the bathroom air-conditioning system 1 of the present invention, in the state where the humidity in the bathroom 101 is saturated, the ejection of the normal mist is stopped and the fine mist is ejected. Thereby, the humidity in the bathroom 101 can be maintained at a predetermined level or more, the amount of mist ejected into the bathroom can be reduced, and the amount of hot water to be used can be reduced.

  In the above-described example, it is determined that the humidity in the bathroom 101 is saturated based on the passage of time from the mist ejection and the temperature in the bathroom 101. However, the bathroom air-conditioning system 1 may include a humidity sensor, and the humidity sensor may determine whether or not the humidity in the bathroom 101 is saturated.

  Further, the first mist generating device 2A described above includes a nozzle unit 2C1 that ejects normal mist and a nozzle unit 2C2 that ejects fine mist. In the first state, fine mist is ejected from the nozzle unit 2C2. In the second state, normal mist is ejected from the nozzle unit 2C1.

  However, two sets of nozzle units 2C1 for ejecting normal mist may be provided, and mist may be ejected from one nozzle unit 2C1 in the first state, and mist may be ejected from both nozzle units 2C2 in the second state. .

  The present invention is applied to a bathroom air conditioning system that creates a mist sauna environment in a bathroom by ejecting mist and blowing air.
