Description

  The present invention relates to a pipe switching unit, a hot water supply system, and a room to which these are applied, which are suitable for use in a bathroom unit that ejects hot water or water supplied from a hot water heater. Specifically, in the state where the hot water supply valve, the mist nozzle valve and the drain valve are provided with control means for opening and closing, the drain valve is closed, and hot water from the water heater is ejected through the hot water valve and the mist nozzle valve. The control that closes the hot water supply valve and then opens the drain valve and then closes the mist nozzle valve by the input to stop the supply of hot water from the water heater allows the hot water in the pipeline to be drained and This is designed to prevent water dripping from the nozzle valve and residual water in the pipeline.

  Thus, the bathroom system 1 which applied the pipe line switching unit and the hot water supply system is comprised. Hereinafter, an example of the internal configuration of the electromagnetic valve unit 2A and a control example thereof will be described.

<Solenoid valve unit>
FIG. 2 is a front view showing a configuration example of the electromagnetic valve unit 2A. The electromagnetic valve unit 2A shown in FIG. 2 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 21A 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 is attached to the height H2 from the reference surface. A connecting portion 2b 'is attached to the height H3. The relationship between the three heights is H3> H2> H1. That is, the three connection portions 2a ′ to 2c ′ are attached from the highest position in the order of the connection portion 2a ′, the connection portion 2b ′, and 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' to supply water or hot water from the hot water supply device 4. It is made like. An electromagnetic valve 2e for a mist nozzle, which is an example of a first valve, is attached to one pipe 2j branched from the electromagnetic valve 2d so as to supply water or hot water to the nozzle unit 2C. The downstream side (the other end) of the electromagnetic valve 2e is attached to the connection portion 2b ′.

  An electromagnetic valve 2f, which is an example of a second valve serving as a drain valve, is disposed at a position lower than the electromagnetic valve 2e, and is attached to the other pipe 2k branched from the electromagnetic valve 2d to drain water. To be made. 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 'at the height H1, the electromagnetic valve 2d connected to the connection portion 2a' at the height H2, and the electromagnetic valve connected to the connection portion 2b 'at the height H3. The relationship between the height of the tripartite and the valve 2e can be H3> H2> H1. That is, the three solenoid valves can be arranged from the higher position in the order of the solenoid valve 2e, the solenoid valve 2d, and the solenoid valve 2f.

  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 water (hot water) flowing through the pipe 2j after passing through the electromagnetic valve 2d and outputs a temperature detection signal S7. The temperature detection signal S7 is output from the temperature detection sensor 2h to the power supply unit 2B.

<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 solenoid valve unit 2A, when the solenoid valve 2f is closed and the hot water I from the hot water supply device 4 is ejected through the solenoid valve 2e, the supply of the hot water I from the mist remote controller 7 is stopped. For example, when the mist stop signal S7 is input, the solenoid valve 2d is closed, then the solenoid valve 2f is opened, and then the solenoid valve 2e is closed.

  3A to 3C are diagrams showing an operation example 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 ′. Is supplied to the solenoid 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 ′. Hot water I is ejected from the mist nozzle unit 2C. At this time, the electromagnetic valve 2f for drainage remains closed. Incidentally, when the electromagnetic valve 2f is opened, the hot water I is drained into the drain pipe 2c (see FIG. 1) through the pipe 2k, the electromagnetic valve 2f, and the connecting portion 2c ′.

  Further, at the time of drainage control after stopping the mist operation, the electromagnetic valve 2d shown in FIG. 3B is closed. Next, by opening the electromagnetic valve 2f, residual water (warm water) II from the connection pipe 2b 'is drained through the electromagnetic valve 2f through the pipes 2j and 2k. 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 II in the connection pipe 2b ′, the electromagnetic valve 2e, the pipe 2j, and 2k can be discharged to the drain pan 101c through the electromagnetic valve 2f.

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

  FIG. 4 is a flowchart illustrating an example of control in the power supply unit 2B. In this example, a read-only memory (not shown) of the power supply unit 2B describes a program related to drainage control after the mist operation stop (hereinafter referred to as a control program), and a predetermined time t = 3 seconds is set in the program. An example is given.

  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, the hot water supply solenoid valve 2d is turned OFF in step ST2 based on the control program. For example, the predetermined drive voltage applied to the electromagnetic valve 2d through an electromagnetic valve drive unit (not shown) is set to 0 [V], and the valve is closed.

  Next, the power supply unit 2B turns on the electromagnetic valve 2f for drainage in step ST3 based on the control program. For example, a predetermined driving voltage is applied to the electromagnetic valve 2d through an electromagnetic valve driving unit (not shown) to open the valve. Thereafter, the power supply unit 2B determines whether t time (= 3 seconds) has elapsed in step ST4. In this example, after waiting for t = 3 seconds, the process proceeds to step ST5. If t = 3 seconds have not elapsed, the system waits as it is.

  In step ST5, the power supply unit 2B turns off the electromagnetic valve 2e for mist nozzles. For example, the predetermined drive voltage applied to the electromagnetic valve 2d through the electromagnetic valve drive 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 ST6. For example, the predetermined drive voltage applied to the electromagnetic valve 2f through the electromagnetic valve driving unit is set to 0 [V], and the valve is closed. As a result, as shown in FIG. 3C, all the solenoid valves 2d, 2e, and 2f in the solenoid valve unit are closed.

  Thus, according to 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 hot water supply device 4 is ejected through the electromagnetic valve 2e. When there is a command to stop the supply of hot water I from the hot water supply device 4, the hot water solenoid valve 2d is closed, the drain electromagnetic valve 2f is opened, and then the mist nozzle solenoid valve 2e is closed. Execute.

  By this control, the residual water II in the pipe can be drained to the drain pan 102c through the solenoid valve 2f for drainage, and the drained air III is drawn from the solenoid valve 2e. The remaining water in the pipes 2j and 2k can be prevented.

<Nozzle unit>
5A to 5C are diagrams illustrating a configuration example of the nozzle unit 2C. 5A is a front view of the nozzle unit 2C, FIG. 5B is a plan view seen from the lower side of the nozzle unit 2C, and FIG. 5C is a side view of the nozzle unit 2C.

  In the nozzle unit 2C shown in FIG. 5A, a plurality of nozzles 2m for ejecting mist are arranged in the lower part in the longitudinal direction, three in this case as shown in FIG. It comprises a portion 2Ca and fixed portions 2Cb1 and 2Cb2 arranged on both sides of the movable portion 2Ca in the longitudinal direction. The fixed portions 2Cb1 and 2Cb2 are fixed to the ceiling of the bathroom 101 and pivotally support the movable portion 2Ca so as to be rotatable. As shown in FIG. 5C, the movable portion 2Ca has a structure that can swing left and right with respect to the rotation axis.

  For example, the fixed portion 2Cb1 includes a drive mechanism (not shown) including a motor, a speed reduction mechanism, and the like for rotationally driving the movable portion 2Ca. With this drive mechanism, the movable part 2Ca can be rotated so that the nozzle 2m is directed in a predetermined direction. However, it is possible to adopt a structure in which the direction can be arbitrarily switched manually without providing a drive mechanism for rotationally driving the movable portion 2Ca.

  The fixing portion 2Cb2 includes a connecting portion 2n for connecting the nozzle pipe 2b (see FIG. 1). The hot water I supplied from the nozzle pipe 2b to the connection part 2n is supplied to each nozzle 2m through a pipe in the fixed part 2Cb2 and a pipe in the movable part 2Ca (not shown), and is ejected as mist.

<Bathroom air conditioner>
6 and 7 are diagrams illustrating a configuration example of the bathroom air conditioner 3. FIG. 6 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. 6 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 multi-blade fan 35 that is rotationally driven, a motor 36 that rotationally drives the fan 35, and a fan case 37 that is mounted with the 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. 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, which will be described later, via a cam 40a, and rotates around a shaft 40b to perform an opening / closing operation. 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 a corona discharge is caused by boosting and applying an AC voltage taken from a household AC power source or the like between a pair of electrodes opposed so as to interpose a dielectric, 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). Emits 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 extremely strong activity, they can surround and inactivate airborne bacteria in the air. 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 remove both floating bacteria in the air of the bathroom 101 shown in FIG. 1 to suppress the occurrence of mold and the like.

  FIG. 7 is a perspective view showing an exploded example of the bathroom air conditioner 3. The bathroom air conditioner 3 shown in FIG. 7 has a structure in which the front panel 26 can be removed (disassembled) from the main body case 34. In this example, a temperature detection sensor 69 is attached to a portion corresponding to the suction port 38 of the main body case 34. The temperature detection sensor 69 is for detecting the temperature of the bathroom 101.

  In FIG. 7, the lower surface of the main body case 34 is opened 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. A filter 47 (not shown) is replaceably attached to the back side of the suction grill 45 of the front panel 26. 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.

  8A to 8C are diagrams illustrating an operation example of the bathroom air conditioner 3. FIG. 8A 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.

  Further, as shown in FIG. 8A, when the damper 40 is set to the circulation position and the fan 35 is driven to rotate by the motor 36, air is sucked from the suction port 38 and blown out from the blower outlet 41 through the circulation air passage 43a. 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. 8B is a cross-sectional view showing a state example in which the damper 40 is fully opened. According to the bathroom air conditioner 3 shown in FIG. 8B, when the damper 40 is fully opened, the air passage to the air outlet 41 is blocked, and the ventilation air passage 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. 8C 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. 8C, 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 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. 8A, the circulation air passage 43a from the suction port 38 to the blowout port 41 is formed in the fan part 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. . Thereby, when the motor 36 is rotationally driven with the damper 40 as the circulation position, when the heater unit 33 is driven, hot air can be blown into the bathroom 101 while circulating the air in the bathroom 101. .

  When the position of the damper 40 is in the ventilation position shown in FIG. 8B, 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 motor 36 is rotationally driven with the damper 40 as a 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. 8C, both the circulation air passage 43a from the suction port 38 to the blowout port 41 and the ventilation air passage 43b from the suction port 38 to the exhaust port 42 in the fan portion 32 are provided. 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.

  Accordingly, when the 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. The 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 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 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 supply hot water is high, the hot water I is taken from the high temperature portion intake pipe 62a, and when the temperature of the supply hot water is low, the switch valve 62c takes the warm water I 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.

<Control system for bathroom air conditioner and mist generator>
FIG. 12 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. 12 includes a control unit 5A having a CPU (Central Processing Unit). The air conditioning remote controller 6 described above is connected to the control unit 5A of the bathroom air conditioner 3 via an electric 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 electric cable 6a. As described above, the temperature detection sensor 69 for detecting the temperature in the bathroom 101 attached to the suction port 38 is connected to the control unit 5A. A temperature detection signal S69 is output from the temperature detection sensor 69 to the control unit 5A.

  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. Control signals S36, S40c, S33, and S44 for controlling operations are supplied from the control unit 5A to the motor 36, the damper motor 40c, the heater unit 33, and the ion generator 44.

  A power supply unit 2B shown in FIG. 12 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 motor 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 each opened by applying a driving voltage of DC 24 [V]. With the drive voltage = 0 [V], each of the solenoid valves 2d, 2e, 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 an electric cable 7a. An operation signal S7a is output from the mist remote controller 7 to the control unit 2Bc via the electric cable 7a. The control unit 2Bc controls the operation of the electromagnetic valve driving unit 2Bb, and controls the direction of the nozzle 2m 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.

  Subsequently, an operation example of the bathroom unit 1 will be described. In this example, the operation example of the bathroom unit 1 will be described by dividing it into six: a bath mist mode, a ventilation standard mode, a bathroom drying mode, a heating mode, a cool air mode, and a clothes drying mode.

<Operation of bathing mist mode>
FIG. 13 is a flowchart showing an operation example of the bathing mist mode. 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 the bath mist is turned off or when a stop is instructed, the mist generating device 2 immediately shifts to drainage control and performs a draining process.

  With these as operating conditions, the bathing mist is turned on in step ST21 of the flowchart shown in FIG. Next, in step ST22, the heater unit 33 of the bathroom air conditioner 3 is energized, and the heater unit 33 is heated. Further, the motor 36 of the bathroom air conditioner 3 is energized and the fan 35 rotates. In this case, the damper 40 is fully closed, that is, the circulation position (see FIG. 8A).

  In this case, since the circulation air path 43a from the suction port 38 to the blower outlet 41 is formed in the fan part 32, the air sucked from the suction port 38 passes through the circulation air path 43a and is warmed by the heater part 33. The air is blown into the bathroom 101 from the air outlet 41 through the air outlet grill 46 of the front panel 26.

  Next, in step ST23, the nozzle unit 2C is controlled and rotated so that the nozzle 2m faces toward the bathtub 101b. This prevents mist from being applied to the person's head.

  Next, wastewater treatment is performed in step ST24. 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 ST25, 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 ST26.

  In step ST26, 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 don't feel 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 ST27, it is determined whether the bathing mist button 7b or 6b has been pressed to turn off the bathing mist or whether the operation stop button 7d has been pressed to instruct a stop. When bathing mist is turned off or stop is instructed, the process proceeds to step ST28. In step ST28, the operation of the bathroom air conditioner 3 is stopped. That is, energization to the heater unit 33 and the motor 36 of the bathroom air conditioner 3 is stopped.

  In step ST29, drainage control is executed to perform drainage processing. In this case, the solenoid valve 2d for hot water supply is closed and the solenoid valve 2f for drainage is opened in the solenoid valve unit 2A (see FIG. 3B). 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 connecting pipe 2b ′, the electromagnetic valve 2e, the pipe 2j and 2k can be discharged to the drain pan 101c through the electromagnetic valve 2f. (See FIGS. 1 and 3B).

  Then, in step ST210, it is determined whether or not a predetermined time necessary for the draining process, for example, t = 3 seconds has elapsed. When the predetermined time has elapsed, the process proceeds to step ST211. In step ST211, 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. 3C). At this time, the nozzle unit 2C is also controlled, and the direction of the nozzle 2m is returned to the original position. With this stop processing, a series of operations in the bathing mist mode is completed in step ST212.

  Step ST23 may not be provided. Further, the mist may be applied to the human body by directing the nozzle 2m toward the washing place 101e. Furthermore, an operation button (not shown) is provided on the air conditioning remote controller 6 or the mist remote controller 7 so that the direction of the nozzle 2m can be selected. You may do it.

<Operation of ventilation standard mode>
FIG. 14 is a flowchart illustrating an operation example of the ventilation standard mode. In this example, when the ventilation button 6g is pushed by the air-conditioning remote controller 6 and the ventilation standard is turned on, the ventilation standard mode is set, and the operation of this mode is started. For example, in step ST51 of the flowchart shown in FIG. 14, the operation is started when the ventilation standard is turned on.

  Next, in step ST52, the motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is fully opened, that is, the ventilation position (see FIG. 8B).

  In this case, since the ventilation air passage 43b from the suction port 38 to the exhaust port 42 is formed in the fan part 32, the air sucked from the suction port 38 passes through the ventilation air passage 43b and the exhaust port 42, and 1 is exhausted from the exhaust grill 8a to the outside through the exhaust duct 8 shown in FIG. 1 (ventilation operation). Thereby, steam and moisture in the bathroom 101 are exhausted.

  Next, in step ST53, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, the operation of the fan ventilation operation of the bathroom air conditioner 3 is stopped in step ST54, and thereafter, the series of operations in the ventilation standard mode ends in step ST55.

<Operation in bathroom drying mode>
FIG. 15 is a flowchart illustrating an operation example of the bathroom drying mode. In this example, when the ventilation button 6g is pressed by the air-conditioning remote controller 6 and the bathroom drying is turned on, the bathroom drying mode is set, and the operation in this mode is started. For example, in step ST81 of the flowchart shown in FIG. 15, the operation starts when the bathroom drying is turned on.

  Next, in step ST82, the motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is set to an intermediate position between the circulation position and the ventilation position, that is, the circulation ventilation position (see FIG. 8C).

  In this case, since both the circulation air path 43a from the suction port 38 to the blower outlet 41 and the ventilation air path 43b from the suction port 38 to the exhaust port 42 are formed in the fan part 32, the air sucked from the suction port 38 Is partly blown into the bathroom 101 through the circulation air passage 43a from the air outlet 41 through the air outlet grill 46 of the front panel 26, and the other is passed through the ventilation air passage 43b and the exhaust port 42, as shown in FIG. Exhaust air is exhausted from the exhaust grill 8a through the exhaust duct 8 shown (circulation ventilation operation). Thereby, steam and moisture in the bathroom 101 are exhausted while circulating the air in the bathroom 101.

  In step ST82, the ion generator 44 generates the aforementioned positive ions and negative ions. Thus, since positive ions and negative ions are released into the bathroom 101 in a state where the circulation ventilation operation is performed, generation of mold on the inner wall and floor surface of the bathroom 101 can be suppressed.

  Next, in step ST83, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST84, the circulation ventilation operation and the ion generation operation of the bathroom air conditioner 3 are stopped, and then, in step ST85, a series of operations in the bathroom drying mode ends.

<Operation in heating mode>
FIG. 16 is a flowchart illustrating an operation example of the heating mode. In this example, when the heating button 6f is pressed by the air conditioning remote controller 6 to turn on the heating, the heating mode is set, and the operation of this mode is started. For example, in step ST91 of the flowchart shown in FIG. 16, the operation is started by turning on the heating.

  Next, in step ST92, the heater unit 33 of the bathroom air conditioner 3 is energized, and the heater unit 33 is heated. Further, the motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is fully closed, that is, the circulation position (see FIG. 8A).

  In this case, since the circulation air path 43a from the suction port 38 to the blower outlet 41 is formed in the fan part 32, the air sucked from the suction port 38 passes through the circulation air path 43a and is warmed by the heater part 33. Then, the air is blown out from the air outlet 41 into the bathroom 101 through the air outlet grill 46 of the front panel 26 (circulation operation). Thereby, the inside of the bathroom 101 is warmed.

  Next, in step ST93, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, the operation of the bathroom air conditioner 3 is stopped in step ST94. That is, energization to the heater unit 33 and the motor 36 of the bathroom air conditioner 3 is stopped. Thereafter, in step ST95, a series of operations in the heating mode ends.

<Operation in cool breeze mode>
FIG. 17 is a flowchart illustrating an operation example of the cool breeze mode. In this example, when the cool air button 6e is pressed by the air conditioner remote controller 6 to turn on the cool air, the cool air mode is set and the operation of this mode is started. For example, in step ST111 of the flowchart shown in FIG. 17, the operation is started by turning on the cool breeze.

  Next, in step ST112, the motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is set to an intermediate position between the circulation position and the ventilation position, that is, the circulation ventilation position (see FIG. 8C).

  In this case, since both the circulation air path 43a from the suction port 38 to the blower outlet 41 and the ventilation air path 43b from the suction port 38 to the exhaust port 42 are formed in the fan part 32, the air sucked from the suction port 38 Is partly blown into the bathroom 101 through the circulation air passage 43a from the air outlet 41 through the air outlet grill 46 of the front panel 26, and the other is passed through the ventilation air passage 43b and the exhaust port 42, as shown in FIG. Exhaust air is exhausted from the exhaust grill 8a through the exhaust duct 8 shown (circulation ventilation operation). Thereby, steam and moisture in the bathroom 101 are exhausted while circulating the air in the bathroom 101.

  Next, in step ST113, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST114, the operation of the circulation ventilation operation of the bathroom air conditioner 3 is stopped, and then, in step ST115, the series of operations in the cool air mode ends.

<Operation in clothes drying mode>
FIG. 18 is a flowchart illustrating an operation example of the clothes drying mode. In this example, when the clothes drying button 6d is pressed by the air-conditioning remote controller 6 and the clothes drying is turned on, the clothes drying mode is set, and the operation of this mode is started. For example, in step ST131 of the flowchart shown in FIG. 18, the operation starts when the clothes drying is turned on.

  Next, in step ST132, the heater unit 33 of the bathroom air conditioner 3 is energized, and the heater unit 33 is heated. Further, the motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is set to an intermediate position between the circulation position and the ventilation position, that is, the circulation ventilation position (see FIG. 8C).

  In this case, in the fan part 32, both the circulation air path 43a from the suction port 38 to the blower outlet 41 and the ventilation air path 43b from the suction port 38 to the exhaust port 42 are formed. A part of the air sucked from the suction port 38 passes through the circulation air passage 43a, is heated by the heater 33, and blown out from the blower outlet 41 into the bathroom 101 through the blowout grill 46 of the front panel 26. Passes through the ventilation air passage 43b and the exhaust port 42, and is further exhausted from the exhaust grill 8a to the outside through the exhaust duct 8 shown in FIG. 1 (circulation ventilation operation). As a result, while the air in the bathroom 101 is circulated, the moisture in the bathroom 101 is exhausted, and the clothes are dried.

  Next, in step ST133, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST134, the operation of the circulation ventilation operation of the bathroom air conditioner 3 is stopped, and then, in step ST135, the series of operations in the clothes drying mode is completed.

The electric cables 7a and 80a are wired, for example, on the back side of the bathroom side surface. The electromagnetic valve unit 2A ″ and the power supply unit 2B are configured.

  FIG. 20 is a conceptual diagram showing another example of piping in the electromagnetic valve unit. A solenoid valve unit 2A ″ shown in FIG. 20 is suitable for the floor-standing mist generator 2 shown in FIG. 19 and has a housing 2A ′. In this example as well, one side of the housing 2A ′ is provided. Is opened, the arrangement of the electromagnetic valves 2d, 2e and 2f in the electromagnetic valve unit can be seen.

A connecting portion 2b 'is attached to the height H3 from the surface.The relationship between the three heights is H3> H2> H1, that is, the three connecting portions 2a' to 2c 'are connected to the connecting portion 2a. ', The connecting portion 2b', and the connecting portion 2c 'are attached in this order from the highest position.

  In this example, an electromagnetic valve 2d for water supply or hot water supply is attached to the connection portion 2a 'inside the housing 2A' so that water or hot water from the hot water supply device 4 is supplied. A pipe 2i connected to the electromagnetic valve 2d is branched in a T shape. One of the pipes 2j ′ is provided with a solenoid valve 2e for a mist nozzle so as to supply water or hot water to the nozzle unit 2C.

In addition, in order to prevent water leakage from the blowing air path 18 side to the motor 15 side, the shaft 15a between the propeller fan 16 and the nozzle mounting portion 21 is provided with a shielding blade 22. The shielding blade 22 is, for example, a disk whose bottom surface has a wave shape, and rotates together with the propeller fan 16.

  The shielding blade 22 covers the base portion of the shaft 15a of the motor 15 protruding from the nozzle mounting portion 21, thereby repelling mist and the like diffused upward against the propeller fan 16 to prevent water leakage to the motor 15 side. Moreover, by making the lower surface of the shielding blade 22 into a wave shape, the mist is diffused to promote atomization.

  Further, the blowout air passage 18 and the blowout air passage 19 shown in FIG. 22 communicate with each other via a blowout air passage communication port 24 formed in the air passage forming wall portion 17. The blowout air passage connection port 24 is formed so as to penetrate the air passage forming wall portion 17 in the vicinity of the height equivalent to the attachment position of the propeller fan 16, and the mesh plate portion 24a is attached thereto. The net-like plate part 24a is formed of, for example, a fine wire mesh, and atomizes the mist passing through the blowout air passage connection port 24.

  In the main body case 14, the lower part of the blowing air passage 18 is opened to form the air outlet 18 a, and the lower part of each blowing air passage 19 is opened to form the air outlet 19 a. Thereby, it connects with the blowing wind path 19 from the blowing wind path 18 via the blowing wind path connection port 24, and the wind path which leads to the blower outlet 19a is formed.

  Further, the main body case 14 includes a front panel 26 'at the lower part. The front panel 26 'has a blowout grill 26a, communicates with the blowout port 18a and the blowout port 19a, and blows out the atomized mist. The main body case 14 includes a hook portion 14a for fixing the front panel 26 'and the front panel 26' is detachably attached (see FIG. 21).

  In this example, the mist generating device 2E may be provided with an auxiliary mist nozzle 27 at the outlet 19a, for example, so that mist can be blown out preliminarily at the operation start stage or the like. As the auxiliary mist nozzle 27, for example, one outlet 19a is provided with an auxiliary mist nozzle 27a having a small mist droplet diameter, and the other outlet 19a is provided with an auxiliary mist nozzle 27b having a coarse mist droplet diameter. And it is good also as a structure which blows off mist from which a water droplet diameter differs as needed. In the mist atomization method described above, a net-like one having a small diameter may be used instead of the propeller fan.

  23 is a configuration diagram illustrating a cross-sectional example of the mist generating device 2E illustrated in FIG. Each suction air passage 20 and the blowout air passage 18 shown in FIG. 23 are communicated with each other via a suction air passage communication port 23 formed in the air passage forming wall portion 17. The suction air passage communication port 23 is formed so as to penetrate the upper portion of the air passage forming wall portion 17 higher than the mounting position of the propeller fan 16. In this example, the lower part of each suction air path 20 is opened, and the suction inlet 20a is formed.

  Here, when air flows from the suction air passage 20 through the suction air passage communication port 23 to the blowout air passage 18, for example, the upper portion of the suction air passage 20 is configured with a curved surface so that turbulence does not occur. For this reason, for example, the four corners of the upper part of the main body case 14 may be configured with curved surfaces having large diameters. As a result, an air passage is formed from each suction port 20a through each suction air passage 20 to the blowout air passage 18 through the suction air passage communication port 23 to reach the air outlet 18a. The front panel 26 'includes a suction grille 26b that communicates with the suction port 20a and sucks air.
