(Embodiment 1)
FIG. 1 is a diagram showing an overall configuration of a mist sauna apparatus according to the present embodiment.

  The figure is a partial cross-sectional view of the mist sauna device as viewed from the side with the mist sauna device attached to the ceiling of a sauna space such as a bathroom, and the lower part of the figure is a sauna space such as a bathroom.

  A circulation fan 3 is provided in one space obtained by dividing the inside of the casing 2 attached to the ceiling 1 by a partition plate 2a, and the air in the lower sauna space is circulated as indicated by an arrow A by driving the circulation fan 3. A heating means 5 such as a heater and a mist nozzle 6 are provided in the circulation air passage 4 for this purpose.

  The mist nozzle 6 is connected to a hot water pipe 9 and a cold water pipe 10 via a hot water valve 7 and a cold water valve 8, respectively. The hot water pipe 9 is connected to an external water heater (not shown) or the like, and the cold water pipe 10 is connected to a water supply pipe (not shown).

  A ventilation fan 11 is provided in the other space in the casing 2 divided into two by the partition plate 2a. By driving the ventilation fan 11, an exhaust flow as shown by arrow B is generated, and the sauna room Air is exhausted to the outside through an exhaust duct (not shown).

  The control device 12 is attached to the inside of the casing 2 or an external cold place.

  The suction temperature sensor 13 is placed near the entrance of the circulation air passage 4 for the purpose of controlling the driving of the heating means 5 and is connected to the control device 12.

  FIG. 2 is a block diagram showing the configuration of the electrical system.

  The control device 12 is configured around a CPU 14 such as a microcomputer.

  As an input of the CPU 14, a suction temperature sensor 13 and a setting operation unit 15 are connected.

  In a general sauna apparatus of this type, the setting operation unit 15 includes a switch for selecting an operation mode to be described later, a timer time limit setting switch for timer operation, an operation start / stop switch, and the like.

  Further, a cleaning switch 16 is connected as an input of the CPU 14, and this description will be described later.

  Relays 17, 18, 19, 20, and 21 are connected as outputs of the CPU 14, and the control device 12 is configured by these relays.

  The circulation fans 3, the heating means 5, the ventilation fan 11, the hot water valve 7, and the cold water valve 8 described in FIG. 1 are connected to the relays 17 to 21, respectively.

  Next, a general operation mode of this type of sauna apparatus will be described with reference to FIGS. 1 and 2 and FIG.

  FIG. 3 is a diagram showing the operation mode and the operation of the electrical components, where a circle indicates that the components are driven (actuated).

  The heating operation is an operation for bringing the bathroom to a warm temperature in winter, and the circulation fan 3 and the heating means 5 are driven to circulate while heating the air in the bathroom so that the temperature in the bathroom is adjusted to an appropriate temperature. .

  In the drying operation, in addition to the heating operation, the ventilation fan 11 is driven to heat the clothes suspended in the bathroom, and the moisture evaporated from the clothes is discharged outdoors to dry the clothes.

  The cool breeze operation is mainly used in the summer, and drives the circulation fan 3 and the ventilation fan 11 to generate a wind flow in the bathroom to give the bather a cool breeze.

  The ventilation operation is used throughout the seasons, and only the ventilation fan 11 is driven to discharge the air in the bathroom. New air is supplied from a gallery on the bathroom door.

  The sauna operation is an operation for making the inside of the bathroom into a sauna space controlled to a humidity and temperature suitable for sweating. When the hot water valve 7 is driven, hot water mist is jetted from the mist nozzle 6, The air is humidified, and the circulation fan 3 and the heating means 5 are driven to circulate the air in the bathroom while heating, thereby maintaining the humidity and temperature in the bathroom in an appropriate state.

  Next, the operation of the present embodiment will be described with reference to FIGS.

  FIG. 4 is a flowchart for explaining the operation of the control device of the present embodiment.

  In S (step) 1, the control device 12 checks whether or not the cleaning switch 16 is pressed, and subsequently checks whether or not the heating operation is finished in S2. The determination of the end of the heating operation is the end of the timer period in the case of the timer operation or the case where the user operates the switch for stopping the heating. This corresponds to the end of bathing.

  Next, in S3, it is checked whether or not the sauna operation is completed according to the same determination criteria as S2.

  If any of the above S1 to S3 is YES, then in S4, the hot water valve 7 is driven intermittently. As a result, a mist of hot water is jetted from the mist nozzle 6, and this mist collides with the wall surface of the bathroom to wash away the detergent and dirt adhering to the wall surface. Since the hot water valve 7 is intermittently driven (for example, intermittently every 2 seconds), the strength of the mist collision is increased and the cleaning effect is enhanced.

  The above hot water mist injection is continued for a predetermined time (for example, 3 minutes) (S5), and in the next S6, the hot water valve 7 is closed and the cold water valve 8 is driven. As a result, a mist of cold water is jetted from the mist nozzle 6, and the mist collides with the wall surface to cool the wall surface. The wall surface cleaning also proceeds during the injection of the cold water mist. The injection of the cold water mist is continued for a predetermined time (for example, 3 minutes) (S7), and in the next S8, the cold water valve 8 is closed to drive the circulation fan 3, and then the ventilation fan 11 is driven in S9.

  As a result, an air flow is generated in the bathroom, and the air in the bathroom humidified by evaporating moisture on the wall surface is discharged to the outside, and drying in the bathroom proceeds.

  This operation continues for a predetermined time (for example, 20 minutes) (S10), the circulation fan 3 is stopped at the next S11, and it is checked whether the operation of the ventilation fan 11 is continued at the next S12.

  Whether or not to continue the operation of the ventilation fan 11 is determined by whether or not the user has switched on the ventilation for 24 hours. If the ventilation is set for 24 hours, the operation is continued as it is. The ventilation fan 11 stops and the series of operations ends.

  The operation of the control device 12 described above is implemented in the form of a CPU program in which the RAM, ROM, counter, etc. in the CPU 14 work together.

  As described above, the mist sauna device of the present embodiment is configured to inject hot water mist by the mist injection means (mist nozzle 6) after the heating operation or sauna operation, and then inject cold water mist. It cleans the bathroom walls contaminated by bathing and sauna use to keep the bathroom clean. In addition, since the wall surface is rapidly cooled by the injection of cold water, it is possible to prevent the occurrence of mold on the tile joints.

  In addition, since the ventilation fan is continuously operated, the inside of the bathroom can be dried, and it is effective in preventing the occurrence of mold.

  Further, since the circulation fan is driven for a predetermined time in addition to the ventilation fan, the air in the bathroom is agitated and drying is performed efficiently.

  In addition, since an operation switch (cleaning switch 16) that can be operated by the user is provided so that the user can clean the bathroom at any time, it is contaminated by normal bathing (for example, spring and autumn) without heating or sauna operation. The bathroom can be cleaned.

  In addition, since the mist injection is performed intermittently, the cleaning effect of the wall surface is improved, the time is shortened, and water is saved.

  In the description of the overall configuration in FIG. 1, the description has been made with the configuration having the circulation fan and the ventilation fan. However, the mist sauna device is configured by using only the circulation fan to configure the exhaust air path with the exhaust damper. In this case, the explanation of the driving of the ventilation fan in FIG. 4 is the damper driving for exhaust.

  In the description of the operation of FIG. 4, the circulation fan and the ventilation fan are driven (S8, S9) after the chilled water valve is stopped, but this may be performed simultaneously with the driving of the chilled water valve (S6). .

  Further, in S6 in FIG. 4, the cold water valve continuously injects cold water mist, but it may be intermittently injected as in S4.

  Further, in S2 and S3 in FIG. 4, the process proceeds to S4 based on the end of the timer time period or the user's switch operation, but the person in the bathroom as shown in FIG. 2 is detected. If a human sensor is provided and no person is detected in the bathroom during heating operation or sauna operation, the bathroom washing operation in steps S4 and after may be performed.

(Embodiment 2)
In the present embodiment, the bathroom cleaning operation described in the first embodiment is performed by a shower nozzle (shower injection means) provided separately from the mist nozzle held by the mist sauna device. Since this is the same as FIG. 1, only the portion related to the shower nozzle will be described.

  5, the shower nozzle 22 has a structure in which hot water is supplied from the hot water pipe 9 through the hot water valve 23 and cold water is supplied from the cold water pipe 10 through the cold water valve 24.

  FIG. 6 is an enlarged view showing the configuration of the shower nozzle 22.

  Fig. (A) is a side sectional view, and Fig. (B) is a plan view of Fig. (A) as viewed from below.

  In FIG. 1 (a), hot water or cold water is supplied from above and is jetted from a number of holes 22a in the jet direction 22b.

  A large number of holes 22a are provided on the circumference of the outer edge as shown in FIG. (B). Therefore, from the large number of holes 22a, a range of the solid angle θ1 to the solid angle θ2 in FIG. The doughnut-shaped injection is performed when the horizontal cross section is seen from above.

  According to such an injection nozzle, the size of the mist sprayed from the mist nozzle of the sauna device is 1 millimeter or less, whereas the size of the spray water droplet can be set to several millimeters, and Because the momentum can be increased, the wall cleaning effect is great.

  In addition, water can be saved without spraying in the downward direction that does not contribute to the cleaning effect.

  As described above, the sauna apparatus of the present invention can keep the sauna room clean and dry with a simple configuration. Moreover, since generation | occurrence | production of mold | fungi can be prevented for this reason, it can apply not only to the sauna apparatus for residence but to the sauna apparatus for other uses, such as business use.
