  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
Embodiment 1 of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is used about the same part as a prior art example, and detailed description is abbreviate | omitted.

  First, a schematic configuration of the bathroom sauna apparatus in the present invention will be described.

  FIG. 1 is a simple exploded view showing a schematic configuration of a bathroom sauna apparatus according to an embodiment of the present invention. As shown in FIG. 1, the bathroom sauna apparatus 1 includes an exterior body 2 and a front panel 3 that form an outer shell, a sauna module 4 that sucks air in the bathroom, heats and humidifies it, and then blows it back into the bathroom, and a plate heat exchanger 5. The ventilation unit 8 is provided on one surface of the exterior body 2 and connected to the opening 7 communicating with the air passage, and the control device 9 controls these components. Each specific configuration will be described below.

  As shown in FIG. 2, the front panel 3 that forms the bathroom side surface of the exterior body 2 is a suction port 103 for sucking air in the bathroom, and for blowing out the heated and humidified air to the outside of the bathroom sauna device 1. An air outlet 102 is provided. Moreover, the filter 10 is provided in the sauna module 4 side of the suction inlet 103, and it has the structure which prevents the penetration | invasion of a fine dust and dust when circulating the air in a bathroom. Further, a louver 11 is provided at the blowout port 102 for changing the blowing direction of the heated and humidified air, and the louver 11 is freely operated by a louver driving motor 12 connected to the control device 9. The blowing direction can be varied in any direction.

  As shown in FIG. 3, in the sauna module 4, an air passage 104 that connects the suction port 103 and the air outlet 102 of the front panel 3 is provided, and a control provided on the air inlet 103 side of the air passage 104. The cross flow fan 107 as a blowing means connected to the motor 13 whose rotation number can be freely changed by the device 9 rotates to blow air into the sauna module 4. A coil 14 which is a heat exchanger for air heating as a heating means is provided on the upstream side of the cross flow fan 107, and hot water is supplied to the coil 14 from the heat supply unit 6 to pass through the coil 14 and the bathroom. The air flowing in from the air is heated, and it becomes possible to blow high-temperature air. A humidifying unit 15 is provided on the downstream side of the cross flow fan 107 in the air blowing path 104. Hot water (for example, 40 to 80 ° C.) is supplied from the heat supply unit 6 to the ejection nozzle 105 serving as a humidifying means provided in the humidification unit 15, and the supplied hot water is sprayed as fine water droplets from the ejection nozzle 105. In the present embodiment, the air passage 104 is configured so that the air blowing direction is substantially vertically downward, and the spray nozzle 105 is installed so that the spray direction of the hot water sprayed from the spray nozzle 105 is substantially vertically downward. Yes. Here, “substantially vertically downward” means within 45 ° with respect to the vertical direction. According to this installation direction, since the direction of movement of the sprayed water droplets does not change greatly, the fine water droplets sprayed from the ejection nozzle 105 do not come close to each other, and the air passage 104 is moved to recontact each water droplet. Therefore, it can be blown out while maintaining the fine shape. At this time, the sprayed water droplet crushing means 16 is provided in front of the spraying direction, and the sprayed water droplet is changed into a finer shape using the sprayed water droplet crushing means 16. Here, with respect to fine water droplets (for example, a water droplet diameter of 100 μm or less), the water droplets that are carried along with the air to be blown to the outlet 102 to humidify the interior of the bathroom and could not be crushed into fine water droplets, go to the drainage section 112 Head. Among the fine water droplets carried with the blown air, water droplets having a relatively large water droplet diameter (for example, water droplet diameters of 10 to 100 μm) are collected by the eliminator 17 provided on the air outlet 102 side of the humidifying unit 15 and are drained. Head to.

The eliminator 17 is made of a coarse mesh material, and does not require a large-scale structure such as a meandering air passage using the conventional ventilation guide plate 113, and the pressure loss can be made relatively small. Moisture directed toward the drainage part 112 passes through the drainage pipe 18 connected to the drainage part 112 and is drained outside the apparatus. The drainage part 112 is provided at the lowermost part of the humidification part 15 and has a slope on the bottom surface so that the drainage pipe connection part becomes the lowermost end so that excess water does not stay in the humidification part. At this time, the larger the angle of the drainage gradient on the bottom surface, the better. However, it is desirable to ensure that the excess water in the humidifying section is drained by ensuring a gradient of 5 ° or more. Similarly, the drain pipe 18 connected to the outside of the apparatus can be installed with an equivalent gradient of 5 ° or more to prevent the excess water from staying in the apparatus. Further, the drainage part 112 is provided with a float switch 19, and when the water level rise of the drainage part 112 is detected and the predetermined water level is exceeded, the control device 9 stops the water supply to the ejection nozzle 105 to humidify.

The humidifying hot water circulation circuit 22 is connected to the plate heat exchanger 5 to heat the plate heat exchanger 5. As shown in FIG. 7, the plate heat exchanger 5 is configured by alternately arranging two paths, a high temperature side path 30 and a low temperature side path 31, which are blocked by the heat transfer wall 29. The low temperature side liquid is heated by exchanging heat through the heat transfer wall 29 by circulating the humidified water used for humidification to the low temperature side path 31 in the opposite direction. The circulating hot water that has exited the coil 14 and the plate heat exchanger 5 passes through the heating hot water circulation circuit 21 and the humidifying hot water circulation circuit 22 again, flows into the junction 24, and the circulating hot water that has joined the one path passes to the heat source. Then, it is heated again and the supply is repeated. The tap water supplied from the liquid supply means passes through the water supply path 23 and is connected to the low temperature side path 31 of the plate heat exchanger 5. The tap water exiting the plate heat exchanger 5 flows again into the ejection nozzle 105 through the water supply path 23.

(Embodiment 2)
Embodiment 2 of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is used about the same part as a prior art example, and detailed description is abbreviate | omitted.

  First, a schematic configuration of the bathroom sauna apparatus in the present invention will be described.

  FIG. 1 is a simple exploded view showing a schematic configuration of a bathroom sauna apparatus according to an embodiment of the present invention. As shown in FIG. 1, the bathroom sauna apparatus 1 includes an exterior body 2 and a front panel 3 that form an outer shell, a sauna module 4 that sucks air in the bathroom, heats and humidifies it, and then blows it back into the bathroom, and a plate heat exchanger 5. The ventilation unit 8 is provided on one surface of the exterior body 2 and connected to the opening 7 communicating with the air passage, and the control device 9 controls these components. Each specific configuration will be described below.

  As shown in FIG. 2, the front panel 3 that forms the bathroom side surface of the exterior body 2 is a suction port 103 for sucking air in the bathroom, and for blowing out the heated and humidified air to the outside of the bathroom sauna device 1. An air outlet 102 is provided. Moreover, the filter 10 is provided in the sauna module 4 side of the suction inlet 103, and it has the structure which prevents the penetration | invasion of a fine dust and dust when circulating the air in a bathroom. Further, a louver 11 is provided at the blowout port 102 for changing the blowing direction of the heated and humidified air, and the louver 11 is freely operated by a louver driving motor 12 connected to the control device 9. The blowing direction can be varied in any direction.

  As shown in FIG. 3, in the sauna module 4, an air passage 104 that connects the suction port 103 and the air outlet 102 of the front panel 3 is provided, and a control provided on the air inlet 103 side of the air passage 104. The cross flow fan 107 as a blowing means connected to the motor 13 whose rotation number can be freely changed by the device 9 rotates to blow air into the sauna module 4. A coil 14 which is a heat exchanger for air heating as a heating means is provided on the upstream side of the cross flow fan 107, and hot water is supplied to the coil 14 from the heat supply unit 6 to pass through the coil 14 and the bathroom. The air flowing in from the air is heated, and it becomes possible to blow high-temperature air. A humidifying unit 15 is provided on the downstream side of the cross flow fan 107 in the air blowing path 104. Hot water (for example, 40 to 80 ° C.) is supplied from the heat supply unit 6 to the ejection nozzle 105 serving as a humidifying means provided in the humidification unit 15, and the supplied hot water is sprayed as fine water droplets from the ejection nozzle 105. In the present embodiment, the air passage 104 is configured so that the air blowing direction is substantially vertically downward, and the spray nozzle 105 is installed so that the spray direction of the hot water sprayed from the spray nozzle 105 is substantially vertically upward. Yes. Here, “substantially vertically below” and “above” mean that the angle is within 45 ° with respect to the vertical direction. The water droplets ejected from the ejection nozzle 105 are separated into smaller water droplets by obtaining larger energy. When the installation direction in which the air passing through the air blowing path 104 and the water droplet sprayed from the ejection nozzle 105 are opposed to each other as in the present embodiment is taken, the energy of the water droplet is increased by increasing the relative speed of the air and the water droplet, It becomes possible to separate into finer water droplets. In addition, by making air and water droplets face each other, the heat exchange rate is increased, and the surface area of the water droplets is increased because the water droplets are crushed into fine water droplets. Therefore, the water droplets are easily evaporated, and the amount of humidification is easily increased. At this time, the sprayed water droplet crushing means 16 is provided in front of the spraying direction, and the sprayed water droplet is changed into a finer shape using the sprayed water droplet crushing means 16. Here, with respect to fine water droplets (for example, a water droplet diameter of 100 μm or less), the water droplets that are carried along with the air to be blown to the outlet 102 to humidify the interior of the bathroom and could not be crushed into fine water droplets, go to the drainage section 112 Head. Among the fine water droplets carried with the blown air, water droplets having a relatively large water droplet diameter (for example, water droplet diameters of 10 to 100 μm) are collected by the eliminator 17 provided on the air outlet 102 side of the humidifying unit 15 and are drained. Head to. Fine water droplets (water droplet diameter of 10 μm or less) that have passed through the eliminator 17 are supplied to the bathroom through the air outlet 102 together with the air heated by the coil 14, and heat and humidify the interior of the bathroom. The eliminator 17 is made of a coarse mesh material, and does not require a large-scale structure such as a meandering air passage using the conventional ventilation guide plate 113, and the pressure loss can be made relatively small. Moisture directed toward the drainage part 112 passes through the drainage pipe 18 connected to the drainage part 112 and is drained outside the apparatus. The drainage part 112 is provided at the lowermost part of the humidification part 15 and has a slope on the bottom surface so that the drainage pipe connection part becomes the lowermost end so that excess water does not stay in the humidification part. At this time, the larger the angle of the drainage gradient on the bottom surface, the better. However, it is desirable to ensure that the excess water in the humidifying section is drained by ensuring a gradient of 5 ° or more. Similarly, the drain pipe 18 connected to the outside of the apparatus can be installed with an equivalent gradient of 5 ° or more to prevent the excess water from staying in the apparatus. Further, the drainage part 112 is provided with a float switch 19, and when the water level rise of the drainage part 112 is detected and the predetermined water level is exceeded, the control device 9 stops the water supply to the ejection nozzle 105 to humidify. Water leakage from the part 15 is prevented.

The humidifying hot water circulation circuit 22 is connected to the plate heat exchanger 5 to heat the plate heat exchanger 5. As shown in FIG. 7, the plate heat exchanger 5 is configured by alternately arranging two paths, a high temperature side path 30 and a low temperature side path 31, which are blocked by the heat transfer wall 29. The low temperature side liquid is heated by exchanging heat through the heat transfer wall 29 by circulating the humidified water used for humidification to the low temperature side path 31 in the opposite direction. The circulating hot water that has exited the coil 14 and the plate heat exchanger 5 passes through the heating hot water circulation circuit 21 and the humidifying hot water circulation circuit 22 again, flows into the junction 24, and the circulating hot water that has joined the one path passes to the heat source. Then, it is heated again and the supply is repeated. The tap water supplied from the liquid supply means passes through the water supply path 23 and is connected to the low temperature side path 31 of the plate heat exchanger 5. The tap water exiting the plate heat exchanger 5 flows again into the ejection nozzle 105 through the water supply path 23. The tap water in the water supply path 23 that has become hot due to heat exchange is sprayed from the ejection nozzle 105 to form fine hot water droplets, and is blown into the bathroom together with the heated bathroom air.

The amount of heating and humidification can be changed by adjusting. The thermal valve 25 is a type of valve that opens and closes the valve by increasing the temperature of the valve support connected to the valve body by supplying electric power and expanding and deforming the valve support. Further, an electromagnetic valve 26 is provided on the upstream side of the plate heat exchanger 5 on the water supply path 23, and the supply amount of the humidified water can be changed by controlling the opening and closing of the water supply. The electromagnetic valve 26 is a valve that opens and closes a valve that uses electromagnetic force by an electric signal.

When a certain amount of time has elapsed and the temperature and humidity in the bathroom reach a predetermined value, the number of revolutions of the motor 13 is changed, and the amount of heating and humidification is changed. After that, when a certain amount of time passes and the temperature and humidity in the bathroom exceed a predetermined value, the rotation speed of the motor 13 is changed to adjust the temperature and humidity in the bathroom, and the heating hot water circulation circuit 21 and the humidification hot water circulation are changed. The temperature and humidity in the bathroom are controlled by repeatedly opening and closing the thermal valve 25 provided in the circuit 22 and the electromagnetic valve 26 provided in the water supply path 23. When the sauna operation is stopped, the operation of the motor 13 in the sauna module 4 is stopped, and the thermal valve 25 provided in the heating hot water circulation circuit 21 and the humidifying hot water circulation circuit 22 and the electromagnetic valve 26 provided in the water supply path 23 are provided. close.

  First, a schematic configuration of the bathroom sauna apparatus in the present invention will be described.

  FIG. 1 is a simple exploded view showing a schematic configuration of a bathroom sauna apparatus according to an embodiment of the present invention. As shown in FIG. 1, the bathroom sauna apparatus 1 includes an exterior body 2 and a front panel 3 that form an outer shell, a sauna module 4 that sucks air in the bathroom, heats and humidifies it, and then blows it back into the bathroom, and a plate heat exchanger 5. The ventilation unit 8 is provided on one surface of the exterior body 2 and connected to the opening 7 communicating with the air passage, and the control device 9 controls these components. Each specific configuration will be described below.

  As shown in FIG. 2, the front panel 3 that forms the bathroom side surface of the exterior body 2 is a suction port 103 for sucking air in the bathroom, and for blowing out the heated and humidified air to the outside of the bathroom sauna device 1. An air outlet 102 is provided. Moreover, the filter 10 is provided in the sauna module 4 side of the suction inlet 103, and it has the structure which prevents the penetration | invasion of a fine dust and dust when circulating the air in a bathroom. Further, a louver 11 is provided at the blowout port 102 for changing the blowing direction of the heated and humidified air, and the louver 11 is freely operated by a louver driving motor 12 connected to the control device 9. The blowing direction can be varied in any direction.

  As shown in FIG. 3, in the sauna module 4, an air passage 104 that connects the suction port 103 and the air outlet 102 of the front panel 3 is provided, and a control provided on the air inlet 103 side of the air passage 104. The cross flow fan 107 as a blowing means connected to the motor 13 whose rotation number can be freely changed by the device 9 rotates to blow air into the sauna module 4. A coil 14 which is a heat exchanger for air heating as a heating means is provided on the upstream side of the cross flow fan 107, and hot water is supplied to the coil 14 from the heat supply unit 6 to pass through the coil 14 and the bathroom. The air flowing in from the air is heated, and it becomes possible to blow high-temperature air. A humidifying unit 15 is provided on the downstream side of the cross flow fan 107 in the air blowing path 104. Hot water (for example, 40 to 80 ° C.) is supplied from the heat supply unit 6 to the ejection nozzle 105 serving as a humidifying means provided in the humidification unit 15, and the supplied hot water is sprayed as fine water droplets from the ejection nozzle 105. In the present embodiment, the air passage 104 is configured so that the air blowing direction is substantially vertically upward, and the spray nozzle 105 is installed so that the spray direction of the hot water sprayed from the spray nozzle 105 is substantially vertically upward. Yes. Here, “substantially vertically upward” means within 45 ° with respect to the vertical direction. According to this installation direction, since the direction of movement of the sprayed water droplets does not change significantly, the fine water droplets sprayed from the ejection nozzle 105 do not come close to each other and move through the air passage 104 to recontact each water droplet. Since it can carry to the blower outlet 102, it becomes possible to blow out, maintaining a fine shape. In addition, since the large-diameter water droplets drop by gravity substantially downward in the vertical direction against the air blowing direction in the air passage 104 and head toward the drainage portion 112, only a certain amount of water droplets can be ejected from the air outlet 102. . At this time, the sprayed water droplet crushing means 16 is provided in front of the spraying direction, and the sprayed water droplet is changed into a finer shape using the sprayed water droplet crushing means 16. Here, with respect to fine water droplets (for example, a water droplet diameter of 100 μm or less), the water droplets that are carried along with the air to be blown to the outlet 102 to humidify the interior of the bathroom and could not be crushed into fine water droplets, go to the drainage section 112 Head. Among the fine water droplets carried with the blown air, water droplets having a relatively large water droplet diameter (for example, water droplet diameters of 10 to 100 μm) are collected by the eliminator 17 provided on the air outlet 102 side of the humidifying unit 15 and are drained.

The eliminator 17 is made of a coarse mesh material, and does not require a large-scale structure such as a meandering air passage using the conventional ventilation guide plate 113, and the pressure loss can be made relatively small. Moisture directed toward the drainage part 112 passes through the drainage pipe 18 connected to the drainage part 112 and is drained outside the apparatus. The drainage part 112 is provided at the lowermost part of the humidification part 15 and has a slope on the bottom surface so that the drainage pipe connection part becomes the lowermost end so that excess water does not stay in the humidification part. At this time, the larger the angle of the drainage gradient on the bottom surface, the better. However, it is desirable to ensure that the excess water in the humidifying section is drained by ensuring a gradient of 5 ° or more. Similarly, the drain pipe 18 connected to the outside of the apparatus can be installed with an equivalent gradient of 5 ° or more to prevent the excess water from staying in the apparatus. Further, the drainage part 112 is provided with a float switch 19, and when the water level rise of the drainage part 112 is detected and the predetermined water level is exceeded, the control device 9 stops the water supply to the ejection nozzle 105 to humidify. Water leakage from the part 15 is prevented.

The humidifying hot water circulation circuit 22 is connected to the plate heat exchanger 5 to heat the plate heat exchanger 5. As shown in FIG. 7, the plate heat exchanger 5 is configured by alternately arranging two paths, a high temperature side path 30 and a low temperature side path 31, which are blocked by the heat transfer wall 29. The low temperature side liquid is heated by exchanging heat through the heat transfer wall 29 by circulating the humidified water used for humidification to the low temperature side path 31 in the opposite direction. The circulating hot water that has exited the coil 14 and the plate heat exchanger 5 passes through the heating hot water circulation circuit 21 and the humidifying hot water circulation circuit 22 again, flows into the junction 24, and the circulating hot water that has joined the one path passes to the heat source. Then, it is heated again and the supply is repeated.

(Embodiment 4)
Embodiment 4 of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is used about the same part as a prior art example, and detailed description is abbreviate | omitted.

  First, a schematic configuration of the bathroom sauna apparatus in the present invention will be described.

  FIG. 1 is a simple exploded view showing a schematic configuration of a bathroom sauna apparatus according to an embodiment of the present invention. As shown in FIG. 1, the bathroom sauna apparatus 1 includes an exterior body 2 and a front panel 3 that form an outer shell, a sauna module 4 that sucks air in the bathroom, heats and humidifies it, and then blows it back into the bathroom, and a plate heat exchanger 5. The ventilation unit 8 is provided on one surface of the exterior body 2 and connected to the opening 7 communicating with the air passage, and the control device 9 controls these components. Each specific configuration will be described below.

  As shown in FIG. 2, the front panel 3 that forms the bathroom side surface of the exterior body 2 is a suction port 103 for sucking air in the bathroom, and for blowing out the heated and humidified air to the outside of the bathroom sauna device 1. An air outlet 102 is provided. Moreover, the filter 10 is provided in the sauna module 4 side of the suction inlet 103, and it has the structure which prevents the penetration | invasion of a fine dust and dust when circulating the air in a bathroom. Further, a louver 11 is provided at the blowout port 102 for changing the blowing direction of the heated and humidified air, and the louver 11 is freely operated by a louver driving motor 12 connected to the control device 9. The blowing direction can be varied in any direction.

  As shown in FIG. 3, in the sauna module 4, an air passage 104 that connects the suction port 103 and the air outlet 102 of the front panel 3 is provided, and a control provided on the air inlet 103 side of the air passage 104. The cross flow fan 107 as a blowing means connected to the motor 13 whose rotation number can be freely changed by the device 9 rotates to blow air into the sauna module 4. A coil 14 which is a heat exchanger for air heating as a heating means is provided on the upstream side of the cross flow fan 107, and hot water is supplied to the coil 14 from the heat supply unit 6 to pass through the coil 14 and the bathroom. The air flowing in from the air is heated, and it becomes possible to blow high-temperature air. A humidifying unit 15 is provided on the downstream side of the cross flow fan 107 in the air blowing path 104. Hot water (for example, 40 to 80 ° C.) is supplied from the heat supply unit 6 to the ejection nozzle 105 serving as a humidifying means provided in the humidification unit 15, and the supplied hot water is sprayed as fine water droplets from the ejection nozzle 105. In the present embodiment, the air flow path 104 is configured so that the air blowing direction is substantially vertically upward, and the spray nozzle 105 is installed so that the spray direction of the hot water sprayed from the spray nozzle 105 is substantially vertically downward. Yes. Here, “substantially vertically upward and downward” means that the angle is within 45 ° with respect to the vertical direction. The water droplets ejected from the ejection nozzle 105 are separated into smaller water droplets by obtaining larger energy. When the installation direction in which the air passing through the air blowing path 104 and the water droplet sprayed from the ejection nozzle 105 are opposed to each other as in the present embodiment is taken, the energy of the water droplet is increased by increasing the relative speed of the air and the water droplet, It becomes possible to separate into finer water droplets. In addition, by making air and water droplets face each other, the heat exchange rate is increased, and the surface area of the water droplets is increased because the water droplets are crushed into fine water droplets. Therefore, the water droplets are easily evaporated, and the amount of humidification is easily increased. In addition, since the large-diameter water droplets drop by gravity substantially downward in the vertical direction against the air blowing direction in the air passage 104 and head toward the drainage portion 112, only a certain amount of water droplets can be ejected from the air outlet 102. . At this time, the sprayed water droplet crushing means 16 is provided in front of the spraying direction, and the sprayed water droplet is changed into a finer shape using the sprayed water droplet crushing means 16. Here, with respect to fine water droplets (for example, a water droplet diameter of 100 μm or less), the water droplets that are carried along with the air to be blown to the outlet 102 to humidify the interior of the bathroom and could not be crushed into fine water droplets, go to the drainage section 112 Head. Among the fine water droplets carried with the blown air, water droplets having a relatively large water droplet diameter (for example, water droplet diameters of 10 to 100 μm) are collected by the eliminator 17 provided on the air outlet 102 side of the humidifying unit 15 and are drained. Head to. Fine water droplets (water droplet diameter of 10 μm or less) that have passed through the eliminator 17 are supplied to the bathroom through the air outlet 102 together with the air heated by the coil 14, and heat and humidify the interior of the bathroom. The eliminator 17 is made of a coarse mesh material, and does not require a large-scale structure such as a meandering air passage using the conventional ventilation guide plate 113, and the pressure loss can be made relatively small. Moisture directed toward the drainage part 112 passes through the drainage pipe 18 connected to the drainage part 112 and is drained outside the apparatus. The drainage part 112 is provided at the lowermost part of the humidification part 15 and has a slope on the bottom surface so that the drainage pipe connection part becomes the lowermost end so that excess water does not stay in the humidification part. At this time, the larger the angle of the drainage gradient on the bottom surface, the better. However, it is desirable to ensure that the excess water in the humidifying section is drained by ensuring a gradient of 5 ° or more. Similarly, the drain pipe 18 connected to the outside of the apparatus can be installed with an equivalent gradient of 5 ° or more to prevent the excess water from staying in the apparatus. Further, the drainage part 112 is provided with a float switch 19, and when the water level rise of the drainage part 112 is detected and the predetermined water level is exceeded, the control device 9 stops the water supply to the ejection nozzle 105 to humidify. Water leakage from the part 15 is prevented.
