DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a first example of the system bus of the present invention.
1 shows an embodiment of the present invention. Note that the same parts as those in FIG. 8 are described with the same numbers. FIG. 1 shows only a main part of the system bus of the present invention, and omits a water heater and a water supply source. In the figure, reference numeral 1 denotes a bathroom, in which a bathtub 2 is provided. 21 heats water supplied from a water supply pipe 22 with a gas burner or the like to produce steam,
It is a steamer for flowing this steam through the pipe 23 or the pipe 24. The pipe 23 is connected to a steam spout (hereinafter referred to as a steam spout) 25 provided inside the bathroom 1, and the pipe 24 passes through a heat exchanger 27 of a ventilation dryer 26 provided at the ceiling of the bathroom 1 and Drain pipe 28.

The operation of the steamer 21 and the ventilation dryer 26 is controlled by the controller 29.

When used as a steam bath, steam is blown into the interior of the bathroom 1 through a steam outlet 25 by passing steam through a pipe 23. Thus, the entire interior of the bathroom 1 is filled with steam to form a steam bath.

At this time, the louver 14 provided on the wall or the door (not shown) of the bathroom 1 and the duct 30 of the ventilation dryer 26 are closed, so that the interior of the bathroom 1 is closed, so to speak. Spills have been prevented.

When used as a bathroom dryer, the steam of the steamer 21 passes through the pipe 24 and passes through the heat exchanger 27 of the ventilation dryer 26. At this time, the blower 31 operates to circulate the air inside the bathroom 1 through the heat exchanger 27, heat the air inside the bathroom 1 with the heat of steam, and allow some air to flow through the duct 30 to perform ventilation. . Then, the steam that has passed through the heat exchanger 27 and returned to the water is
Released from outside.

As described above, by switching and using steam generated from one steamer, it is possible to realize both functions of a steam bath and a ventilation dryer. From another point of view, the efficiency of use of the steamer 21 is improved.

FIG. 2 shows an embodiment of the second invention. FIG.
The same parts as those described above are denoted by the same reference numerals.

Here, the steam supplied from the steamer 21 through the pipe 32 is branched into the pipe 23 and the pipe 24 and switched by the switching valve 33. The controller 34 is used as a steam bath or as a dryer. In response to the selection signal from the operation switch 35, a signal is sent to the switching valve 33 to switch the supply destination of the steam and to control the operation of the steamer 21 and the ventilation dryer 26.

The operation switch 35 is actually installed inside the bathroom 1 and enables these controls from inside the bathroom 1.

When the use of the steam bath is selected by the operation switch 35, steam is supplied to the pipe 23 by the switching valve 33, and the steam is discharged from the steam outlet 25 into the interior of the bathroom 1. Therefore, the entire interior of the bathroom 1 is filled with steam to form a steam bath.

At this time, as in FIG. 1, the ducts 30 of the louver 14 and the ventilation dryer 26 are closed to keep the interior of the bathroom 1 in a closed state, and the outflow of steam to the outside is prevented.

When the ventilation mode is selected by the operation switch 35 after using the steam sauna, the operation of the steamer 21 is stopped, and at the same time the blower 31 of the ventilation dryer 26 is operated, so that the interior of the bathroom 1 is filled. The water vapor is discharged from the duct 30 to the outside.

When used as a bathroom dryer, the switching valve 33 is switched by the signal of the operation switch 35. Thereby, the steam supplied from the steamer 21 passes through the pipe 24 and passes through the heat exchanger 27 of the ventilation dryer 26. At this time, since the blower 31 operates to circulate the air inside the bathroom 1 through the heat exchanger 27, the air inside the bathroom 1 is heated and a part of the air is ventilated through the duct 30. The water vapor that has returned to the water after passing through the heat exchanger 27 is discharged from the drain pipe 28 to the outside.

According to the present embodiment, since the switching valve 33 is provided separately from the steamer 21 and the steam passage is switched by the operation of the controller 34 and the operation switch 35, the steamer 21 simply generates steam. It just needs to have a function. Therefore, for example, in addition to the instantaneous steamer by gas combustion, the steamer 2 is used in a conventional steam boiler or the like.
It can be used instead of 1.

FIG. 3 shows a further improvement of the configuration shown in FIG. 1 and 2, the steam that has passed through the heat exchanger 27 of the ventilation dryer 26 returns to water and is discharged from the water pipe 28 to the outside. However, in such a configuration, if the drying load condition varies depending on the size and temperature of the interior of the bathroom 1, the interior of the water distribution pipe 28 may not always return to water. In such a case, it is dangerous to release the water vapor to the outside as it is, so it is necessary to discharge the water vapor to an outdoor drainage channel.

In the configuration shown in FIG. 3, the structure which returns to the water through the heat exchanger 27 is returned to the interior of the bathroom 1, and is provided in the drain (not shown) of the bathroom 1 without providing a separate drain outside. Can be drained directly. In this case, as described above, the condenser 36 is provided in the drainage pipe 28 in order to prevent the remaining water vapor from being released into the interior of the bathroom 1 and lowering the drying efficiency. The water vapor is reliably returned to the water, and this water flows into the piping 23 through which the water vapor passes when used as a steam bath. Therefore,
During the ventilation drying, the steam is discharged from the steam outlet 25 into the bathroom 1 as cooling water.

FIG. 4 shows an embodiment of the third invention. The pipe 37 through which the steam of the steamer 21 passes passes through the heat exchanger 27 of the ventilation dryer 38 and leads from the pipe 39 to the steam outlet 25. The controller 40 outputs a drive signal to the steamer 21 and the ventilation dryer 38 according to a signal from the changeover switch 41. The changeover switch 41 is normally installed and operated inside the bathroom 1 or in a dressing room (not shown).

In the present embodiment, there is no need to provide two steam pipes from the steamer 21 as shown in FIG. 1 and, unlike FIGS. 2 and 3, there is no need for the switching valve 33. These functions are performed by the controller 40 instead.

The operation of the controller 40 will be described with reference to the flowchart shown in FIG. 5 and the ventilation dryer 38 with the configuration shown in FIG. In the figure, I is a routine when the steam bus is used. Similarly, II is a routine indicating a ventilation mode, III is a drying mode, and IV is a routine indicating a stop mode.

Now, when the steam bath is selected by the changeover switch 41, the routine I is selected, and the operation of the steamer 21 is started. However, since the blower 31 of the ventilation dryer 38 does not operate, the steam passes through the heat exchanger 27. The gas is jetted from the steam jet port 25 into the bathroom 1 through the pipe 39. At this time, the controller 40 closes the duct 30 by rotating the damper 42 shown in FIG. 6 in the direction a so that the water vapor inside the bathroom 1 is not discharged outside through the duct 30.
Further, the gallery 14 of the bathroom 1 is also closed. During the operation of the steam bath, the steam generation amount of the steamer 21 is controlled such that the temperature inside the bathroom 1 is maintained at a predetermined temperature. Further, a timer function may be added to automatically stop when the vehicle is driven for a predetermined period of time, or to notify that a certain period of time has passed.

When the ventilation mode is selected by the changeover switch 41, the flow goes through the routine II of FIG. 5, the steamer 21 does not operate, the blower 31 operates, and the damper 42 is switched to the side b shown in FIG. Is sucked through the suction port 43 and discharged outside through the duct 30. At this time, by opening the gallery 14, fresh air is sucked into the interior of the bathroom 1 and ventilated.

When the bathroom is to be ventilated and dried, the changeover switch 41 selects the routine III shown in FIG. Thereby, the steamer 21 and the blower 31 are operated, and the damper 42 is switched to the side a shown in FIG.

The steam flows into the heat exchanger 27 from the pipe 37, where the heat is absorbed by the air inside the bathroom 1 sucked from the suction port 43 by the blower 31. The water is drained from the outlet 25 into the bathroom 1.

The air inside the bathroom 1 is heated by the heat exchanger 27 and returns from the outlet 44 to the bathroom. The damper 42 opens the duct 30 at regular intervals to ventilate with fresh air.
By repeating the above operation cycle, the temperature inside the bathroom 1 is raised, and the air inside the bathroom 1 is ventilated and dried. At this time, room temperature control is performed so that the temperature of the bathroom 1 is maintained at a predetermined temperature, similarly to the case of the routine I in the steam bath mode. Timer control may also be added.

Here, if the temperature inside the bathroom 1 rises to some extent, the load on the heat exchanger 27 will decrease.
There is a possibility that a part of the steam will enter the return pipe 39 without completely returning to the water. Therefore, since steam is jetted from the steam jet port 25, the drying efficiency is reduced. In the embodiment shown in FIG. 3, a condenser 36 is provided to prevent this. In this embodiment, a valve 45 and an inlet temperature sensor 46 are provided in the steam inlet pipe 37 shown in FIG. A temperature sensor 47 is provided, and the difference between the inlet temperature and the outlet temperature is detected in the steam amount control routine of FIG. 5, and when the difference decreases, it is determined that steam has entered the return pipe 39, and the valve 45 is throttled. Reduce the inflow of steam. This arrangement allows for drainage with complete water without the need for a condenser. In addition to the above-described configuration using the valve 45, the same effect can be obtained by a configuration in which the steam generation amount of the steamer 21 is directly controlled.

The ventilation dryer 38 may have a structure in which two fans for circulation and ventilation are provided in addition to the structure shown in FIG.

As described above, by adopting the configurations shown in FIGS. 4, 5 and 6, the related equipment and piping in the bathroom are greatly simplified.

FIG. 7 is an embodiment for explaining the fourth invention. In the figure, the switching valve 33 branches into a passage leading to the steam jet port 25 through the steam piping 23 by the switching valve 33 and a passage leading to the reheating adapter 49 as hot water heating means through the reheating piping 48. The drive of the switching valve 33 and the steamer 21 is controlled by the controller 50, and the passage of the steam is switched by the operation unit 51 provided inside the bathroom 1.

From the reheating adapter 49, steam is jetted toward the inside of the bathtub 2. Accordingly, the water inside the bathtub 2 is heated and agitated by the heat of the steam. In addition to the configuration in which the reheating adapter 49 is configured to directly blow out steam into the bathtub 1, a heat exchanger may be configured to allow steam to pass therethrough so as to exchange heat with surrounding water for heating. In this case, a configuration may be adopted in which the water vapor cooled by the heat exchange is released into the interior of the bathroom 1.

The case where the steamer 21 is used as a heat source for various devices inside the bathroom 1 has been described above. However, since the steamer 21 is configured to heat water to be steam,
Depending on the water quality, the steamer's capacity and the durability of the steam piping may differ significantly. Then the water supply pipe 22 of the steamer 21
These disadvantages have been eliminated by providing a water softener and a pure water purifier.

[0048]

As described above, according to the system bus of the present invention, the following various effects can be obtained. (1) Piping for steam ejection and piping for ventilation dryer from steamer, and using steamer heat source of steamer to fill bathroom with steam by first configuration that controls steamer and ventilation dryer by controller. It can also be used for drying the bathroom in addition to drying. Therefore, one heat source device is used for both humidification and drying, so that the use efficiency of the steamer is improved and the number of heat source devices installed outdoors is reduced, resulting in a small space. Furthermore, since the heat source of the ventilation dryer is steam, high-temperature warm air can be obtained, and the drying time can be reduced. (2) A three-way switching valve is provided to switch the steam coming out of the steamer between the passage used for the steam bath and the passage leading to the ventilation dryer. By providing a configuration in which an operation switch for operating the valve is provided, the switching operation between the steam bath and the ventilation dryer can be performed with a single touch using the operation switch, thereby simplifying the operation. (3) Further, as shown in FIG. 4, the heat pipe of the ventilation dryer is connected in the middle of the steam passage from the steamer to the steam ejector, and the steam pipe is formed as a single pipe in series. Simplification improves workability, and further reduces heat loss, thereby saving energy. (4) Also, by using a configuration in which one of the three-way switching valves connected to the steam pipe is connected to a steam blower and the other is connected to hot water heating means for heating hot water in the bathtub, the steam is used to follow the hot water in the bathtub. Heating is also possible, and a single steamer can be used as a water heater.
