Description

  The present invention relates to a mist sauna device that includes a mist nozzle and supplies hot water mist sprayed from the mist nozzle to a bathroom.

  Conventionally, as this type of mist sauna device, an electrolytic cell and a nozzle channel for supplying acidic water (hypochlorous acid water) generated in the electrolytic cell to the mist nozzle are provided, and the acidic water mist is supplied to the bathroom. In addition, there is known one that can obtain a bactericidal effect on the wall surface of a bathroom or the skin surface of a bather (see, for example, Patent Document 1). In this apparatus, hot water from a water heater is supplied to an electrolytic cell through a hot water supply passage, and warm water of acidic water is sprayed from a mist nozzle. A filter is interposed in the hot water supply path.

  In the electrolytic cell, acidic water and alkaline water are generated by electrolysis of water. Alkaline water has an alkaline cleaning effect to remove fats and proteins from waste skin products. Accordingly, it is possible to selectively supply ionized water of one of alkaline and acidic generated in the electrolytic cell to the mist nozzle to obtain a cleaning effect by spraying alkaline water and a sterilizing effect by spraying acidic water. It can also be considered.

By the way, it has been found that when hot water is supplied to the electrolytic cell as in the conventional example, organic halogen compounds such as trihalomethane are easily generated. This is because when the electrolysis is performed in a state where the water temperature is high, the reaction between organic substances in the tap water and chlorine is promoted. It is known that the higher the water temperature, the higher the generation rate of the organic halogen compound (see Non-Patent Document 1), and the electrolysis at a high water temperature further promotes the generation of the organic halogen compound.
Japanese Patent Laid-Open No. 11-316083 Kazuaki Ito, Takako Aizawa, Hiroaki Habutsu, Yasuki Managata (1984) Total organic halogen (TOX) generation ability of river water and its behavior in water purification process, Journal of Water Supply Association 53 (8), 14-21

  This invention makes it the subject to provide the mist sauna apparatus with the electrolytic vessel which enabled it to suppress generation | occurrence | production of organic halogen compounds, such as a trihalomethane, in view of the above point.

  In order to solve the above-described problems, the present invention provides a mist sauna device that includes a mist nozzle and supplies hot water mist sprayed from the mist nozzle to a bathroom. And having a nozzle water channel for supplying ionic water of one polarity to the mist nozzle, normal temperature water is supplied to the electrolytic cell via the water supply channel, and water flowing in the nozzle water channel is heated in the nozzle water channel. A water heating means for warm water is arranged.

  According to the present invention, the normal temperature water supplied through the water supply channel is electrolyzed in the electrolytic cell. Accordingly, generation of organic halogen compounds such as trihalomethane is suppressed as compared with the conventional example in which hot water is electrolyzed. Even if normal temperature water is supplied to the electrolyzer, the ionic water supplied from the electrolyzer to the mist nozzle via the nozzle water channel becomes warm water by heating with the water heating means. It becomes a sauna state and does not impair the original function of the mist sauna device.

  In the conventional example, since the filter is interposed in the hot water supply path, the temperature of the water flowing through the filter becomes high, and there is a possibility that harmful substances once adsorbed on the filter are re-released into the water. On the other hand, in the present invention, the channel on the upstream side of the electrolytic cell is a water supply channel for flowing normal temperature water. And by providing a filter in this water supply channel, it is possible to prevent harmful substances once adsorbed on the filter from being re-released due to the influence of high water temperature.

  Referring to FIG. 1, reference numeral 1 denotes a housing of a bathroom heater installed on the ceiling of the bathroom. A suction port 2 and a blowout port 3 with a variable louver 3a are provided on the lower surface of the housing 1 facing the bathroom. And the ventilation path 4 from the suction inlet 2 to the blower outlet 3 is defined in the housing 1, and the fan 5 and the heat radiator 6 are arrange | positioned in this ventilation path 4. FIG.

  A heat medium circulation path 8 connected to a separately installed heat source unit 7 is connected to the radiator 6. A heating medium valve 9 is interposed in the heating medium circulation path 8, and a heating medium (water, antifreeze liquid, etc.) heated by the heat source device 7 is opened to the radiator 6 by opening the heating medium valve 9. Circulated. Then, the air in the bathroom is sucked into the ventilation path 4 from the suction port 2 by the rotation of the fan 5, heated by the radiator 6, and blown into the bathroom from the blowout port 3 as warm air.

  A mist unit 10 is mounted on the upper surface of the housing 1. A mist nozzle 11 connected to the mist unit 10 by piping is disposed in a portion adjacent to the outlet 3 on the lower surface of the housing 1, and the hot water mist sprayed from the mist nozzle 11 rides on the warm air from the outlet 3. It is supplied to the bathroom.

  The mist unit 10 is provided with an electrolytic cell 12. The inside of the electrolytic cell 12 is partitioned into a first and second pair of electrode chambers 12b and 12c by a diaphragm 12a, and a DC voltage is applied between a pair of electrodes (not shown) disposed in the electrode chambers 12b and 12c. Thus, alkaline ionic water (alkaline water) is generated in the first electrode chamber 12b, and acidic ionic water (acid water) is generated in the second electrode chamber 12c.

  Room temperature water (tap water) is supplied to the electrolytic cell 12 through a water supply passage 13 provided with a water supply valve 14 and a filter 15 downstream thereof. Moreover, the nozzle water channel 16 connected to the mist nozzle 11 and the drainage channel 17 leading to the sewage pipe of the house are provided, and the bipolar chambers 12b and 12c of the electrolytic cell 12 are connected to the nozzle water channel 16 and the drainage channel 17 via the four-way valve 18. I try to connect. The four-way valve 18 connects the first electrode chamber 12b to the nozzle channel 16 and connects the second electrode chamber 12c to the drain channel 17, and connects the second electrode chamber 12c to the nozzle channel 16 and the second electrode chamber 12c. It is possible to switch between a second connection state in which the unipolar chamber 12 b is connected to the drainage channel 17 and a third connection state in which the first and second bipolar chambers 12 b and 12 c are connected to the nozzle water channel 16.

  A liquid heat exchanger 19 and a mist valve 20 on the downstream side thereof are interposed in the nozzle water passage 16, and the temperature of the portion of the nozzle water passage 16 between the liquid heat exchanger 19 and the mist valve 20 is further increased. There is provided a mist temperature sensor 21 for detecting. A heat medium circulation path 8 ′ branched from the heat medium circulation path 8 is connected to the liquid heat exchanger 19, and a mist heat medium valve 22 including a flow rate adjusting valve is connected to the heat medium circulation path 8 ′. It is installed. Thus, the heat medium heated by the heat source device 7 is supplied to the liquid heat exchanger 19 when the mist heat medium valve 22 is opened, and the water flowing through the nozzle water passage 16 is heated by the liquid heat exchanger 19. And is supplied to the mist nozzle 11 as hot water.

  The fan 5, the heating heat medium valve 9, the electrolytic cell 12, the water supply valve 14, the four-way valve 18, the mist valve 20, and the mist heat medium valve 22 are controlled by a controller 23 for a bathroom heater. The controller 23 is communicably connected to a controller for the heat source unit 7 and a remote controller for the bathroom heater. When the mist switch provided in the remote controller is turned on, mist operation control by the controller 23 is executed. In addition, as a mist operation mode by a remote controller, a combined mode in which alkaline water and acidic water are sprayed in order, an alkaline mode in which only alkaline water is sprayed, an acidic mode in which only acidic water is sprayed, and tap water are used as they are. The neutral mode to be sprayed can be selected.

  In the mist operation control, first, an operation command is sent to the heat source device 7 and the heating medium valve 9 and the mist heat medium valve 22 are opened so that the heat medium heated by the heat source device 7 is released from the radiator 6. And the liquid-liquid heat exchanger 19. When the preheating of the radiator 6 and the liquid heat exchanger 19 is completed, the fan 5 is activated and the water supply valve 14 and the mist valve 20 are opened. As a result, hot air blows out from the outlet 3 and hot water heated by the liquid heat exchanger 19 is supplied to the mist nozzle 11 so that the hot water mist sprayed from the mist nozzle 11 rides on the hot air into the bathroom. Supplied, the bathroom becomes hot and humid mist sauna. During the mist operation, temperature control is performed to adjust the flow rate of the heat medium supplied to the liquid heat exchanger 19 by the mist heat medium valve 22 so that the temperature detected by the mist temperature sensor 21 is maintained at the set temperature.

  Here, when the combined mode is selected as the mist operation mode, first, the four-way valve 18 is switched to the first connection state and the electrolytic cell 12 is energized. According to this, alkaline water generated in the first electrode chamber 12b of the electrolytic cell 12 is supplied to the nozzle water channel 16, and warm water mist of alkaline water is supplied to the bathroom to remove fat, protein, etc. from the skin waste products. A cleaning effect is obtained. Then, the four-way valve 18 is switched to the second connection state after a predetermined time has elapsed. According to this, the acidic water produced | generated in the 2nd electrode chamber 12c of the electrolytic cell 12 is supplied to the nozzle water channel 16, and the warm water mist of acidic water is supplied to a bathroom, and the disinfection effect of the skin surface is acquired.

  When the alkaline mode is selected, the four-way valve 18 is maintained in the first connection state, and when the acid mode is selected, the four-way valve 18 is maintained in the second connection state. When the neutral mode is selected, the four-way valve 18 is switched to the third connection state without energizing the electrolytic cell 12, and tap water is supplied to the nozzle channel 16 as it is. When ionic water having one polarity of alkaline and acidic generated in the electrolytic cell 12 is supplied to the nozzle water channel 16, the ionic water having the other polarity is drained to the drainage channel 17.

  By the way, it is also conceivable that hot water heated by a water heater or the like is supplied to the electrolytic cell 12 and the liquid heat exchanger 19 provided in the nozzle water channel 16 is omitted. However, in this case, electrolysis is performed in the electrolytic cell 12 at a high water temperature, the reaction between organic substances in tap water and chlorine is promoted, and organic halogen compounds such as trihalomethane are easily generated. On the other hand, in this embodiment, since normal temperature water is supplied to the electrolytic cell 12, generation | occurrence | production of organic halogen compounds, such as a trihalomethane, is suppressed.

  Further, when hot water is supplied to the electrolytic cell 12, the temperature of the water flowing in the filter interposed in the flow path on the upstream side of the electrolytic cell 12 becomes high, so that harmful substances once adsorbed on the filter may be released again. is there. On the other hand, in this embodiment, since the filter 15 is interposed in the water supply path 13 through which the normal temperature water on the upstream side of the electrolytic cell 12 flows, harmful substances once adsorbed on the filter 15 are re-released due to the influence of the high water temperature. Can be prevented.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the above embodiment, the water heating means for heating the water flowing through the nozzle water channel 16 is configured by the liquid-liquid heat exchanger 19, but the water heating means may be configured by an electric heater. In the above embodiment, alkaline water and acidic water generated in the electrolytic cell 12 can be selectively supplied to the nozzle water channel 16 using the four-way valve 18, but the four-way valve 18 is omitted and the electrolytic cell is provided. It is also possible to supply only one of the alkaline water and acidic water generated at 12 to the nozzle water channel 16.

  Furthermore, in the said embodiment, although the mist sauna apparatus is integrated in the bathroom heater, this invention is applicable similarly to the mist sauna apparatus provided separately from the bathroom heater.
