[0005] [Patent Document 1] JP 2020-118427 A Summary of the Invention [Problem to be solved by the invention]

[0006] In recent years, there has been a demand for more effective steam baths, even in the case of steam baths in bathrooms. However, if the structure of the steam supplier becomes complicated in order to provide an effective steam bath, this leads to an increase in manufacturing costs.

[0007] The present invention has been made in consideration of the above-mentioned conventional situation, and has as its object to provide a water steam supply device that can realize a more effective steam bath in the bathroom while reducing manufacturing costs. [Means for solving the problem]

[0008] The water vapor supply device of the present invention is connected to a water vapor generating device that generates water vapor and supplies the water vapor to a bathroom, A housing disposed in the bathroom; a water vapor flow path provided in the housing, connected to the water vapor generator, through which the water vapor flows; a nozzle provided in the housing, connected to the water vapor flow path, and capable of injecting the water vapor; a storage chamber provided in the housing and positioned above the nozzle, in which a medium having a functional component is placed; a guide passage provided in the housing and configured to guide at least a portion of the water vapor sprayed from the nozzle to the storage chamber; a supply port formed in the housing, opening toward the top of the housing, and connecting the bathroom and the storage room; The medium is placed in the storage chamber through the supply port; The functional ingredient is supplied to the bathroom from the supply port together with the water vapor in the storage chamber.

[0009] In the steam supplying device of the present invention, steam generated by the steam generator flows through the steam flow path and is sprayed from the nozzle. A guide flow path and a storage chamber are formed in the housing. A medium having a functional component is placed in the storage chamber. The storage chamber is connected to the bathroom by a supply port.

[0010] In this steam supplying device, at least a part of the steam sprayed from the nozzle is guided to the storage chamber by the guide flow path. As a result, the steam that reaches the storage chamber is supplied to the bathroom from the supply port. At this time, the functional ingredient is supplied to the bathroom from the supply port together with the steam in the storage chamber.

[0011] However, since water vapor is a gas, the water vapor supplied from the supply port to the bathroom rises within the bathroom. In this regard, since the supply port opens toward the top of the housing, this water vapor supplier can supply not only water vapor but also functional ingredients together with the water vapor from the supply port into the bathroom. As a result, this water vapor supplier allows the bather to enjoy the effects of the functional ingredients while taking a steam bath using water vapor.

[0012] In addition, in this water vapor supplying device, the functional component is supplied to the bathroom from the supply port together with the water vapor, so there is no need for a dedicated nozzle or other device for supplying the functional component to the bathroom. Furthermore, since the medium having the functional component can be placed in the storage chamber through the supply port, there is no need for a dedicated opening for placing the medium having the functional component in the storage chamber. In addition, in this water vapor supplying device, the medium having the functional component can be easily replaced or replenished through the supply port according to the functional component desired by the bather. As a result, this water vapor supplying device can supply the functional component to the bathroom in addition to water vapor, while suppressing the complexity of the configuration.

[0013] Therefore, the steam supplier of the present invention can provide a more effective steam bath in the bathroom while reducing manufacturing costs.

[0014] In the present invention, examples of functional ingredients include, for example, fragrance ingredients with a relaxing effect, amino acid-based ingredients with a skin maintenance effect, hyaluronic acid-based ingredients, etc. Also, examples of the medium having a functional ingredient (hereinafter, appropriately referred to as "medium") include sponges and ceramic balls impregnated with the functional ingredients as described above.

[0015] The medium is preferably housed in a cartridge, which allows for easier replacement or refilling of the medium and also effectively prevents the medium from leaking or falling into the guide channel.

[0016] The housing may be formed with a communication port that intersects with the supply port and communicates with the bathroom, and supplies the water vapor sprayed from the nozzle to the bathroom without passing through the storage chamber. The amount of water vapor supplied from the communication port to the bathroom is preferably greater than the amount of water vapor supplied from the supply port to the bathroom.

[0017] In this case, steam is supplied to the bathroom from the communication port in addition to the supply port, so that steam can be suitably supplied to the bathroom. At this time, the steam supplied to the bathroom from the communication port does not contain functional components. In addition, the amount of steam supplied to the bathroom from the communication port is greater than the amount of steam supplied to the bathroom from the supply port, so that this steam supplying device can prevent the functional components from being excessively supplied to the bathroom. Furthermore, since the communication port is connected to the bathroom while crossing the supply port, the steam supplied to the bathroom from the communication port is less likely to be distributed above the bathroom than the steam supplied to the bathroom from the supply port. Therefore, the amount of steam supplied to the bathroom from the communication port is greater than the amount of steam supplied to the bathroom from the supply port, so that steam can be efficiently supplied to the entire bathroom. Effect of the Invention

[0018] According to the steam supplier of the present invention, it is possible to realize a more effective steam bath in a bathroom while realizing a reduction in manufacturing costs. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, first and second embodiments of the present invention will be described with reference to the drawings.

[0021] Example 1 As shown in Fig. 1, the bathroom system of Example 1 includes a bathroom H, a remote control 2, a water supply tool 4, a bath heating device 3, a connection flow path 5, a pump 7, a hot water heating device 9, a water supply flow path 11, an on-off valve 13, a steam generator 15, a bypass flow path 17, a switching unit 19, and a control device 23. The water supply tool 4 is an example of a "steam supply tool" in the present invention. This bathroom system is used in a house not shown. Note that, for ease of explanation, the bathroom system and the water supply tool 4 are illustrated in a schematic manner in Figs. 1 to 10.

[0022] In this embodiment, the up-down direction and the front-back direction of the bathroom H are defined by the solid arrows shown in Fig. 1. The up-down direction and the front-back direction are perpendicular to each other. In Fig. 2 and subsequent figures, the up-down direction and the front-back direction of the bathroom H are defined in accordance with Fig. 1.

[0023] As shown in Fig. 1, a bathroom H is formed in a house. A bathtub 1 is provided in the bathroom H. The bathtub 1 is formed in a substantially rectangular box shape with an open top, and is capable of storing water inside.

[0024] As shown in FIG. 2, the water supply device 4 includes a housing 25, first to fourth internal flow paths 26a to 26d, first to third check valves 27a to 27c, a nozzle 28, a storage chamber 29, a guide flow path 30, and a supply port 39.

[0025] The housing 25 is composed of a housing body 25a and a cover 25b. The housing body 25a and the cover 25b are made of metal. The housing body 25a is fixed to the bathtub 1. As a result, the housing 25, and therefore the water supply device 4, are placed in the bathroom H. The housing body 25a and the cover 25b may be made of resin. Also, one of the housing body 25a and the cover 25b may be made of metal, and the other of the housing body 25a and the cover 25b may be made of resin.

[0026] The housing main body 25a has a first front wall 251, a first rear wall 252, and a first peripheral wall 253. The first front wall 251 is formed in a disk shape and is located at the front of the housing main body 25a. The first rear wall 252 is formed in a disk shape and is located at the rear of the housing main body 25a. The first peripheral wall 253 is formed in a cylindrical shape. The first peripheral wall 253 is located between the first front wall 251 and the first rear wall 252 in the front-rear direction, and is connected to the first front wall 251 and the first rear wall 252.

[0027] Further, a first connection port 31 and a second connection port 32 are formed in the first front wall 251. The first connection port 31 and the second connection port 32 each penetrate the first front wall 251 in the front-rear direction. As a result, the first connection port 31 and the second connection port 32 each communicate with the inside of the housing main body 25a and the outside of the housing main body 25a.

[0028] The first rear wall 252 is formed with the third to fifth connection ports 33-35 as well as the first to third protrusions 36-38. The third to fifth connection ports 33-35 each penetrate the first rear wall 252 in the front-rear direction. As a result, the third connection port 33 communicates with the inside of the housing main body 25a and the first chamber 41. The fourth connection port 34 communicates with the inside of the housing main body 25a and the second chamber 42. The fifth connection port 35 communicates with the inside of the housing main body 25a and the third chamber 43. The first to third chambers 41-43 will be described later.

[0029] The first to third protrusions 36-38 protrude rearward from the first rear wall 252 at predetermined intervals in the up-down direction. Of the first to third protrusions 36-38, the third protrusion 38 is located at the topmost position. The first protrusion 36 and the second protrusion 37 protrude rearward by the same length. On the other hand, the third protrusion 38 protrudes rearward by a length shorter than the first and second protrusions 36, 37.

[0030] The cover 25b has a second rear wall 254 and a second peripheral wall 255. The second rear wall 254 is formed in a disk shape and is located at the rear end of the cover 25b. The second peripheral wall 255 is connected to the outer periphery of the second rear wall 254 and extends cylindrically forward from the second rear wall 254. The second rear wall 254 and the second peripheral wall 255 form the cover 25b into a bottomed tubular shape. The cover 25b is attached to the housing main body 25a from the rear. As a result, the cover 25b is located behind the housing main body 25a.

[0031] The storage chamber 29 is formed between the first rear wall 252 and the third protruding portion 38 of the housing body 25a and the second rear wall 254 of the cover 25b by attaching the cover 25b to the housing body 25a. A sponge 40 is disposed in the storage chamber 29. The sponge 40 is an example of a "medium having a functional component" in the present invention. The sponge 40 is impregnated with essential oil containing a fragrance component having a relaxing effect, so-called aroma oil. This fragrance component having a relaxing effect corresponds to the "functional component" in the present invention.

[0032] Furthermore, by attaching the cover 25b to the housing main body 25a, a first chamber 41 is formed between the first rear wall 252 and the first protruding portion 36, and the second rear wall 254 and the second peripheral wall 255. Further, a second chamber 42 is formed between the first rear wall 252, the first protruding portion 36 and the second protruding portion 37, and the second rear wall 254. And a third chamber 43 is formed between the first rear wall 252, the second protruding portion 37 and the third protruding portion 38, and the second rear wall 254.

[0033] The first chamber 41, the second chamber 42, the third chamber 43, and the storage chamber 29 are arranged in this order from bottom to top within the housing 25. That is, within the housing 25, the storage chamber 29 is located above the third chamber 43, i.e., it is located at the topmost position among the first chamber 41, the second chamber 42, the third chamber 43, and the storage chamber 29. Furthermore, the first chamber 41 and the second chamber 42 are partitioned by the first protruding portion 36, and the second chamber 42 and the third chamber 43 are partitioned by the second protruding portion 37. Furthermore, the third chamber 43 and the storage chamber 29 are partitioned by the third protruding portion 38.

[0034] The guide flow passage 30 is formed by penetrating a part of the third protruding portion 38 in the vertical direction. As a result, the guide flow passage 30 communicates with the third chamber 43 and the storage chamber 29. In addition, a mesh member 300 is provided in the guide flow passage 30. The mesh member 300 prevents the sponge 40 in the storage chamber 29 from falling into the third chamber 43 while communicating between the third chamber 43 and the storage chamber 29.

[0035] The supply port 39 is formed in the second peripheral wall 255 of the cover 25b. More specifically, the supply port 39 is formed in a position on the second peripheral wall 255 that will be the upper part of the storage chamber 29 when the cover 25b is attached to the housing body 25a. The supply port 39 penetrates the second peripheral wall 255 in the vertical direction and communicates with the storage chamber 29 from above. In this way, the supply port 39 opens toward the top of the housing 25, and communicates between the bathtub 1, and therefore the bathroom H, and the storage chamber 29.

[0036] Here, the supply port 39 is formed to be slightly larger than the sponge 40. This makes it possible to place the sponge 40 in the storage chamber 29 or to remove the sponge 40 from the storage chamber 29 through the supply port 39. Note that the shape of the supply port 39 can be designed as appropriate as long as the sponge 40 can be put in and taken out of the storage chamber 29 through the supply port 39.

[0037] In addition, a first communication port 44 is formed in the second peripheral wall 255 of the cover 25b. The first communication port 44 is formed at a position in the second peripheral wall 255 that is the lower part of the first chamber 41 when the cover 25b is attached to the housing body 25a, that is, at a position opposite the supply port 39 in the circumferential direction of the second peripheral wall 255. The first communication port 44 penetrates the second peripheral wall 255 in the vertical direction and communicates with the first chamber 41 from below. In this way, the first communication port 44 communicates between the bathtub 1 and the first chamber 41 while opening toward the bottom of the housing 25.

[0038] Further, the second communication port 45 and the third communication port 46 are formed in the second rear wall 254 of the cover 25b. The third communication port 46 is an example of a "communication port" in the present invention. The second communication port 45 and the third communication port 46 each penetrate the second rear wall 254 in the front-rear direction. The second communication port 45 and the third communication port 46 are partitioned by the second protruding portion 37. In other words, the second communication port 45 and the third communication port 46 are formed by partitioning a single opening penetrating the second rear wall 254 in the front-rear direction by the second protruding portion 37.

[0039] The second communication port 45 communicates with the second chamber 42 from the rear. The third communication port 46 communicates with the third chamber 43 from the rear. Thus, the second communication port 45 and the third communication port 46 communicate with the bathroom H while being perpendicular to the supply port 39 and the first communication port 44, respectively. In other words, the second communication port 45 communicates with the bathtub 1 and the second chamber 42 in the front-rear direction, and the third communication port 46 communicates with the bathtub 1 and the third chamber 43 in the front-rear direction. Note that the second communication port 45 and the third communication port 46 are not limited to a configuration in which they communicate with the bathroom H while being perpendicular to the supply port 39 and the first communication port 44, but may communicate with the bathroom H while intersecting the supply port 39 and the first communication port 44.

[0040] The first to fourth internal flow paths 26a to 26d are provided in the housing body 25a. One end of the first internal flow path 26a extends into the first connection port 31, and the other end extends into the third connection port 33. As a result, the first internal flow path 26a communicates with the first chamber 41 through the third connection port 33.

[0041] One end of the second internal flow path 26b extends into the second connection port 32, and the other end is connected to one end of the third internal flow path 26c and one end of the fourth internal flow path 26d. The other end of the third internal flow path 26c extends into the fourth connection port 34. As a result, the third internal flow path 26c communicates with the second chamber 42 through the fourth connection port 34. The other end of the fourth internal flow path 26d extends into the fifth connection port 35.

[0042] The first internal flow passage 26a allows water to flow through the inside. The second internal flow passage 26b allows water and water vapor to flow through the inside. The third internal flow passage 26c allows water to flow through the inside. The fourth internal flow passage 26d allows water vapor to flow through the inside. The water includes hot water, which is high temperature water.

[0043] The first check valve 27a is provided in the first internal flow path 26a. The first check valve 27a allows water to flow in the first internal flow path 26a toward the first chamber 41 and thus toward the bathtub 1, while preventing water from flowing from the first chamber 41 side. The second check valve 27b is provided in the third internal flow path 26c. The second check valve 27b allows water to flow from the second chamber 42 side in the third internal flow path 26c, while preventing water from flowing toward the second chamber 42 side. The third check valve 27c is provided in the fourth internal flow path 26d. The third check valve 27c allows water vapor to flow toward the nozzle 28 in the fourth internal flow path 26d, while preventing water from flowing from the third chamber 43 side through the nozzle 28.

[0044] The nozzle 28 is disposed in the third chamber 43. As described above, the storage chamber 29 is located above the third chamber 43 in the housing 25, and therefore the storage chamber 29 is located above the nozzle 28. The nozzle 28 is connected to the other end of the fourth internal flow path 26d through the fifth connection port 35. In this way, the fourth internal flow path 26d and the nozzle 28 are connected.

[0045] The nozzle 28 has a first injection hole 28a and a second injection hole 28b. The nozzle 28 is capable of injecting the water vapor that has flowed through the fourth internal flow passage 26d from the first injection hole 28a and the second injection hole 28b.

[0046] The first injection hole 28a is formed at the rear end of the nozzle 28. The first injection hole 28a faces the inside of the bathtub 1 from the front through the third communication port 46. The second injection hole 28b is formed in the outer peripheral surface of the nozzle 28 at a position forward of the first injection hole 28a. The second injection hole 28b opens upward relative to the outer peripheral surface of the nozzle 28. As a result, the second injection hole 28b faces the guide passage 30 from below while communicating with the third chamber 43.

[0047] As shown in Fig. 1, the remote control 2 is installed in the bathroom H. The remote control 2 can be operated by the bather 10 to select and execute a steam bath operation, a combined operation, a water filling operation, and a reheating operation. Details of the steam bath operation will be described later.

[0048] Bath heating device 3 is installed outside bathroom H. Bath heating device 3 has inlet 3a for letting water flow into the inside and outlet 3b for letting water flow out from the inside. Bath heating device 3 is capable of heating water by heat exchange with heat generated when fuel gas is burned inside.

[0049] The connection flow path 5 is composed of pipes 5a to 5e. One end of the pipe 5a is connected to the first flow path switching valve 19a outside the bathroom H. The pipe 5a extends from the first flow path switching valve 19a toward the bathroom H. As shown in FIG. 2, the other end of the pipe 5a is connected to the second internal flow path 26b through the second connection port 32 of the water supply device 4. As shown in FIG. 1, one end of the pipe 5b is connected to the other ends of the pipes 5c and 12. The other end of the pipe 5b is connected to the first flow path switching valve 19a. One end of the pipe 5c is connected to the inlet 3a of the bath heating device 3. The other end of the pipe 5c is connected to one end of the pipe 5b and the other end of the pipe 12.

[0050] One end of the pipe 5d is connected to the outlet 3b of the bath heating device 3. The other end of the pipe 5d is connected to the second flow path switching valve 19b. One end of the pipe 5e is connected to the second flow path switching valve 19b. The pipe 5e extends from the second flow path switching valve 19b toward the bathroom H. As shown in FIG. 2, the other end of the pipe 5e is connected to the first internal flow path 26a through the first connection port 31 of the water supply device 4. Thus, as shown in FIG. 1, the connection flow path 5 connects the bathtub 1 and the bath heating device 3.

[0051] The pump 7 is provided in the pipe 5c. Thus, the pump 7 is provided in the connecting flow passage 5. The pump 7 can circulate water through the connecting flow passage 5 by operating.

[0052] The hot water heating device 9 is installed outside the bathroom H. The hot water heating device 9 is separate from the bath heating device 3 described above. The hot water heating device 9 has an inlet 9a through which water flows into the inside, and an outlet 9b through which water flows out from the inside. Like the bath heating device 3, the hot water heating device 9 can also heat water by exchanging heat with the heat generated when fuel gas is burned inside.

[0053] The water supply flow path 11 is composed of pipes 11a and 11b. One end of pipe 11a is connected to a water supply source W. The other end of pipe 11a is connected to an inlet 9a of a hot water heater 9. One end of pipe 11b is connected to a kitchen (not shown) or the like in the house. The other end of pipe 11a is connected to an outlet 9b of the hot water heater 9. In this way, the hot water heater 9 is provided in the water supply flow path 11.

[0054] Moreover, one end of pipe 12 is connected to pipe 11b. As a result, the connection flow path 5 and the water supply flow path 11 are connected by pipe 12. In other words, pipe 12 functions as a communication flow path that connects the connection flow path 5 and the water supply flow path 11.

[0055] The on-off valve 13 is provided in the piping 12. The on-off valve 13 opens the piping 12 when in an open state. As a result, the on-off valve 13 allows water to flow from the water supply flow path 11 to the connecting flow path 5 through the piping 12. On the other hand, the on-off valve 13 closes the piping 12 when in a closed state. As a result, the on-off valve 13 prohibits water from flowing from the water supply flow path 11 to the connecting flow path 5 through the piping 12. Although not shown in the figure, the piping 12 is provided with a check valve that prevents water from flowing from the connecting flow path 5 to the water supply flow path 11.

[0056] The steam generator 15 employs a known configuration. Although detailed illustration is omitted, the steam generator 15 is capable of generating steam by heating water that has been introduced into the inside. The steam generator 15 has an inlet 15a for introducing water into the inside, and an outlet 15b for discharging the generated steam.

[0057] The bypass flow passage 17 is composed of a pipe 17a and a pipe 17b. One end of the pipe 17a is connected to the second flow passage switching valve 19b. The other end of the pipe 17a is connected to the inlet 15a of the steam generator 15. One end of the pipe 17b is connected to the outlet 15b of the steam generator 15. The other end of the pipe 17b is connected to the first flow passage switching valve 19a. Thus, the bypass flow passage 17 is connected to the connection flow passage 5 through the pipe 17b and the first flow passage switching valve 19a. The bypass flow passage 17 is also connected to the connection flow passage 5 through the pipe 17a and the second flow passage switching valve 19b. In other words, the bypass flow passage 17 branches off from the connection flow passage 5, connects to the steam generator 15, and merges with the connection flow passage 5 again.

[0058] The switching unit 19 is composed of the above-mentioned first flow path switching valve 19a and second flow path switching valve 19b. The first flow path switching valve 19a can switch among a case where the pipes 5a and 5b communicate with each other while the pipes 5a, 5b and 17b are not connected to each other, a case where the pipes 5a and 17b communicate with each other while the pipes 5a, 17b and 5b are not connected to each other, and a case where the pipes 5a, 5b and 17b are not connected to each other.

[0059] The second flow path switching valve 19b is switchable between a case in which pipes 5d and 5e are connected to each other while pipes 5d, 5e are not connected to pipe 17a, a case in which pipes 5d and 17a are connected to each other while pipes 5d, 17a are not connected to pipe 5e, a case in which pipes 5d, 5e, and 17a are connected to each other, and a case in which pipes 5d, 5e, and 17a are not connected to each other.

[0060] The control device 23 is provided outside the bathroom H. Although detailed illustration is omitted, the control device 23 is composed of semiconductors such as a CPU, RAM, and ROM. The control device 23 is connected to the remote control 2 so as to be able to communicate with it. The control device 23 is also connected to the bath heating device 3, the pump 7, the hot water heating device 9, the on-off valve 13, the steam generator 15, and the switching unit 19 so as to be able to electrically connect to each of them.

[0061] In the bathroom system configured as above, the control device 23 controls the operation of the bath heating device 3, the steam generator 15, the pump 7, etc. while supplying electricity to the bath heating device 3, the steam generator 15, etc. In this way, the control device 23 executes the steam bath operation, combined operation, water filling operation, and reheating operation selected by the bather 10 via the remote control 2. The details are explained below.

[0062] <Steam bath operation> To perform the steam bath operation, the control device 23 activates the steam generator 15 and opens the on-off valve 13, as shown in Fig. 3. The control device 23 also stops the hot water heater 9, the bath heater 3, and the pump 7.

[0063] Furthermore, the control device 23 controls the first flow path switching valve 19a to connect the pipes 5a and 17b, while disconnecting the pipes 5a, 17b from the pipe 5b. As a result, in the water supply tool 4, the fourth internal flow path 26d is connected to the steam generator 15 through the second internal flow path 26b, the pipe 5a, the first flow path switching valve 19a, and the pipe 17b (see FIGS. 3 and 4).

[0064] As shown in FIG. 3, the controller 23 controls the second flow path switching valve 19b to connect the pipe 5d to the pipe 17a and to disconnect the pipes 5d, 17a from the pipe 5e.

[0065] As a result, in water supply flow path 11, water supplied from water supply source W flows from pipe 11b through pipe 12 to connection flow path 5 without being heated by hot water heater 9. The water that has reached connection flow path 5 then flows through pipe 5c, bath heater 3, pipe 5d, and pipe 17a, in that order, to steam generator 15.

[0066] Then, the water is heated in the water vapor generator 15 to become water vapor. This water vapor flows from the outlet 15b through the pipe 17b and then through the pipe 5a. As a result, as shown in Fig. 4, the water vapor reaches the second internal flow path 26b to the fourth internal flow path 26d of the water supply tool 4. In this way, while flowing through the fourth internal flow path 26d, the water vapor is sprayed from the first injection hole 28a and the second injection hole 28b of the nozzle 28, as shown by the dashed arrow in Fig. 4.

[0067] Here, water vapor is injected from second injection hole 28b toward third chamber 43. Then, a part of the water vapor in third chamber 43 flows through guide flow path 30 and reaches storage chamber 29. At this time, the water vapor that has flowed through guide flow path 30 passes through the inside of sponge 40 and reaches storage chamber 29. Then, the water vapor in storage chamber 29 is supplied into bathtub 1 from supply port 39.

[0068] As described above, sponge 40 is impregnated with essential oil. Therefore, in water supply device 4, water vapor that has flowed through guide flow path 30 passes through the inside of sponge 40 and is supplied from supply port 39 into bathtub 1, so that the relaxing aroma components contained in the essential oil, i.e., functional components, are supplied from supply port 39 into bathtub 1 together with water vapor. In other words, the water vapor supplied from supply port 39 into bathtub 1 contains the functional components.

[0069] On the other hand, the water vapor injected from first injection hole 28a is supplied into bathtub 1 from third communication port 46 without passing through third chamber 43, guide passage 30, storage chamber 29, and supply port 39. Furthermore, of the water vapor injected from second injection hole 28b into third chamber 43, the water vapor that does not flow through guide passage 30 is also supplied into bathtub 1 from third communication port 46. That is, in water supply device 4, the water vapor supplied into bathtub 1 from third communication port 46 does not contain any functional component.

[0070] Here, in this water supply device 4, the nozzle 28 is arranged in the third chamber 43 with the first spray hole 28a facing the inside of the bathtub 1 via the third spray hole 46, and the sizes of the first and second spray holes 28a, 28b, the guide passage 30, the supply hole 39 and the third spray hole 46 are each designed so that the amount of water vapor supplied into the bathtub 1 from the third spray hole 46 is greater than the amount of water vapor supplied into the bathtub 1 from the supply hole 39.

[0071] As shown in Fig. 3, when the steam bath is in operation, the bathtub 1 is covered from above with the cover 1a. Therefore, the water vapor supplied into the bathtub 1 from the supply port 39 and the third communication port 46 fills the bathtub 1. Then, the bather 10 can take a steam bath by entering the bathtub 1 filled with water vapor. The steam bath operation ends when the steam bath setting time set in the control device 23 has elapsed, or the bather 10 can end it at will through the remote control 2.

[0072] <Combined operation> To perform the combined operation, the control device 23 activates the hot water heater 9 and the steam generator 15 and opens the on-off valve 13, as shown in Fig. 5. The control device 23 also stops the bath heater 3 and the pump 7.

[0073] Furthermore, the controller 23 controls the first flow path switching valve 19a to communicate between the pipe 5a and the pipe 17b, and to disconnect the pipes 5a, 17b from the pipe 5b. The controller 23 also controls the second flow path switching valve 19b to communicate between the pipes 5d, 5e, and 17a.

[0074] As a result, in the water supply flow passage 11, the water supplied from the water supply source W is heated by the hot water supply heating device 9, and flows from the pipe 11b through the pipe 12 to the connecting flow passage 5. Then, the water that reaches the connecting flow passage 5 flows from the pipe 5c through the bath heating device 3 to the pipe 5d. Then, the water flowing through the pipe 5d flows through the pipe 17a and the pipe 5e. As a result, the water flowing through the pipe 17a is turned into steam in the steam generating device 15. This steam flows through the pipe 17b and the pipe 5a in this order, and reaches the second internal flow passage 26b and the fourth internal flow passage 26d of the water supply tool 4 as shown in FIG. 6. As a result, the steam is supplied into the bathtub 1 in the same manner as during the steam bath operation (see the dashed arrow in FIG. 6). As shown in FIG. 5, during the combined operation, the bathtub 1 is covered from above with the cover material 1a to fill the bathtub 1 with steam.

[0075] 5 and 6, the water flowing through the pipe 5e flows through the first internal flow path 26a of the water supply device 4 and reaches the first chamber 41. The water in the first chamber 41 is then supplied into the bathtub 1 from the first communication port 44. Here, since the water in the first chamber 41 is supplied from the first communication port 44 toward the bottom of the bathtub 1, it is difficult for the steam and water to mix in the bathtub 1.

[0076] Thus, in the combined operation, water flows from the connection flow path 5 to both the inside of the bathtub 1 and the bypass flow path 17, so that in the water supply device 4, not only does water vapor flow through the second internal flow path 26b and the fourth internal flow path 26d via the pipe 5a, but water heated by the hot water supply heater 9 flows through the first internal flow path 26a via the pipe 5e. As a result, in the combined operation, water vapor and water heated by the hot water supply heater 9 are simultaneously supplied from the water supply device 4 to the inside of the bathtub 1. Thus, by performing the combined operation, if the bather 10 desires to take a steam bath in a state where there is no water in the bathtub 1 (hereinafter referred to as a "full-body steam bath") and then a steam bath in a state where water heated to a degree that half of the bather 10 is immersed in is stored in the bathtub 1, the bather 10 can move from a full-body steam bath to a half-body steam bath without interrupting the supply of water vapor to the bathtub 1.

[0077] This combined operation can also be terminated at will by the bather 10 via the remote control 2, or it can be terminated automatically when the water in the bathtub 1 reaches the water filling level set for combined operation in the control device 23.

[0078] <Water filling operation> To execute the water filling operation, the control device 23 activates the hot water heater 9 and opens the on-off valve 13, as shown in Fig. 7. The control device 23 also stops the bath heater 3, the pump 7, and the steam generator 15.

[0079] Furthermore, the controller 23 controls the first flow path switching valve 19a to disconnect the pipes 5a, 5b, and 17b from one another. The controller 23 controls the second flow path switching valve 19b to connect the pipes 5d and 5e, but to disconnect the pipes 5d and 5e from the pipe 17a.

[0080] As a result, in the water supply flow passage 11, the water supplied from the water supply source W is heated by the hot water supply heating device 9. The water heated by the hot water supply heating device 9 flows through the pipe 12, reaches the connecting flow passage 5, and flows through the pipe 5c. The water flowing through the pipe 5c flows toward the bath heater 3, and from the bath heater 3, flows through the pipe 5d and then through the pipe 5e, and further flows through the first internal flow passage 26a of the water supply tool 4 and reaches the first chamber 41, as shown in FIG. The water in the first chamber 41 is then sequentially supplied from the first communication port 44 into the bathtub 1, whereby the water is stored in the bathtub 1.

[0081] This water filling operation is automatically terminated by the control device 23 when the water filling amount reaches a set amount set in the control device 23. The set amount of water filling can be set by the bather 10 at his / her discretion.

[0082] <Reheating operation> To perform the reheating operation, the control device 23 activates the bath heater 3 and the pump 7 as shown in Fig. 9. The control device 23 then stops the hot water heater 9 and the steam generator 15, and closes the on-off valve 13.

[0083] The controller 23 also controls the first flow path switching valve 19a to communicate between the pipes 5a and 5b, while disconnecting the pipes 5a, 5b from the pipe 17b. The controller 23 also controls the second flow path switching valve 19b to communicate between the pipes 5d and 5e, while disconnecting the pipes 5d, 5e from the pipe 17a.

[0084] As a result, as shown in Figures 9 and 10, the pump 7 operates to draw water stored in the bathtub 1 into the second chamber 42 through the second communication port 45 of the water supply device 4. The water drawn into the second chamber 42 then flows through the third internal flow path 26c, the second internal flow path 26b, the pipes 5a, 5b, and 5c in this order, and reaches the bath heating device 3. The water stored in the bathtub 1 is then heated by the bath heating device 3. The water heated by the bath heating device 3 then flows through the pipes 5d and 5e, and then flows through the first internal flow path 26a of the water supply device 4, and is resupplied into the bathtub 1 through the first chamber 41 and the first communication port 44.

[0085] Thus, during the reheating operation, water circulates between bathtub 1 and bath heating device 3 via connecting flow path 5, while water is heated by bath heating device 3 and resupplied to bathtub 1. The reheating operation ends when the reheating time set in control device 23 has elapsed, or bather 10 can end it at will via remote control 2.

[0086] In addition, when the water in the bathtub 1 is stored beyond the water supply device 4, such as during the filling operation and the reheating operation, the sponge 40 can be removed in advance from the storage chamber 29 through the supply port 39 of the water supply device 4.

[0087] In this way, in this bathroom system, functional ingredients are supplied into the bathtub 1 together with water vapor from the supply port 39 of the water supply device 4. Here, since water vapor is a gas, the water vapor supplied into the bathtub 1 from the supply port 39 rises inside the bathtub 1. In this respect, since the supply port 39 opens toward the top of the housing 25, in this water supply device 4, in addition to water vapor, functional ingredients are suitably supplied into the bathtub 1 from the supply port 39 together with the water vapor. As a result, with this water supply device 4, the bather 10 can effectively enjoy the effects of the functional ingredients while taking a steam bath with water vapor during steam bath operation or mixed operation. In other words, the bather 10 can effectively enjoy the relaxing effect of the aromatic ingredients in addition to the refreshing feeling obtained from the steam bath.

[0088] In addition, in this water supply tool 4, since the functional component is supplied from the supply port 39 into the bathtub 1 together with the steam, a dedicated nozzle or other device for supplying the functional component into the bathtub 1 is not required. Furthermore, since the sponge 40 impregnated with the essential oil can be placed in the storage chamber 29 through the supply port 39, the water supply tool 4 does not need to form a dedicated opening for placing the sponge 40 impregnated with the essential oil in the storage chamber 29. In addition, in this water supply tool 4, it is easy for the bather 10 to replace the sponge 40 impregnated with the essential oil according to the functional component desired by the bather 10, or to replenish the sponge 40 with the essential oil by dripping the essential oil from the supply port 39 onto the sponge 40. As a result, the water supply tool 4 can supply the functional component in addition to the steam to the bathtub 1, and thus the bathroom H, while suppressing the complexity of the configuration.

[0089] Therefore, according to the bathroom system of Example 1, it is possible to realize a more effective steam bath in bathroom H while also achieving low manufacturing costs.

[0090] In particular, in the water supply device 4, steam is supplied into the bathtub 1 not only from the supply port 39 but also from the third communication port 46. Here, the steam supplied into the bathtub 1 from the third communication port 46 does not contain functional components. In the water supply device 4, the amount of steam supplied into the bathtub 1 from the third communication port 46 is greater than the amount of steam supplied into the bathtub 1 from the supply port 39. Therefore, the water supply device 4 can prevent the functional components from being excessively supplied into the bathtub 1 while suitably supplying steam into the bathtub 1 through the supply port 39 and the third communication port 46. Furthermore, the steam supplied into the bathtub 1 from the third communication port 46 tends to rise inside the bathtub 1 and fill the bathtub 1 before it comes into contact with the lid body 1a. As a result, the amount of steam supplied into the bathtub 1 from the third communication port 46 is greater than the amount of steam supplied into the bathtub 1 from the supply port 39, so that the water supply device 4 can efficiently supply steam to the entire bathtub 1. Therefore, this water supply tool 4 can efficiently heat the inside of the bathtub 1 by using water vapor.

[0091] In addition to the steam bath operation, the bathroom system can also perform combined operation, water filling operation, and reheating operation, making it highly convenient. Water supply device 4 can not only supply steam and functional ingredients to bathtub 1, but also supply water to bathtub 1 and draw water from bathtub 1. As a result, in this bathroom system, there is no need to provide a water supply device other than water supply device 4 to bathtub 1 when performing combined operation, water filling operation, and reheating operation, making it possible to simplify the configuration accordingly.

[0092] Example 2 The bathroom system of Example 2 is equipped with a water supply device 8 shown in Figure 11 instead of the water supply device 4. Water supply device 8 is also an example of the "water vapor supplier" of the present invention.

[0093] The water supply device 8 comprises a housing 65, a nozzle 68, a storage chamber 69, a guide passage 70, and a supply port 71, and, similar to the water supply device 4 in the bathroom system of Example 1, also comprises first to fourth internal passages 26a to 26d and first to third check valves 27a to 27c.

[0094] The housing 65 is composed of a housing main body 25a and a cover 25c. Like the cover 25b, the cover 25c is also made of metal. The cover 25c has a second rear wall 256 and a second peripheral wall 257. The second rear wall 256 is formed in a disk shape and is located at the rear end of the cover 25c. The second peripheral wall 257 is connected to the outer periphery of the second rear wall 256 and extends forward from the second rear wall 256 in a cylindrical shape. The second rear wall 256 and the second peripheral wall 257 form the cover 25c in a cylindrical shape with a bottom. The cover 25c is attached to the housing main body 25a from the rear. The cover 25c may be made of resin.

[0095] The storage chamber 69 is formed between the first rear wall 252 and the third protruding portion 38 of the housing body 25a and the second rear wall 256 of the cover 25c by attaching the cover 25c to the housing body 25a. A plurality of ceramic balls 60 are arranged in the storage chamber 69 in a state of being housed in a cartridge 61. Each ceramic ball 60 is also an example of the "medium having functional components" in the present invention. Similarly to the sponge 40 described above, each ceramic ball 60 is impregnated with essential oil containing aromatic components having a relaxing effect.

[0096] The cartridge 61 is made of resin and is formed in a generally rectangular box shape with an open top. A plurality of ventilation holes 61a are formed at the bottom end of the cartridge 61. Each ventilation hole 61a is formed smaller than the ceramic ball 60. The material and shape of the cartridge 61 can be designed as appropriate.

[0097] Moreover, by attaching the cover 25b to the housing body 25a, a first chamber 51 is formed between the first rear wall 252 and the first protruding portion 36 and the second rear wall 256 and the second peripheral wall 257. A second chamber 52 is formed between the first rear wall 252, the first protruding portion 36 and the second protruding portion 37 and the second rear wall 256. A third chamber 53 is formed between the first rear wall 252, the second protruding portion 37 and the third protruding portion 38 and the second rear wall 256. The first chamber 51 communicates with the third connection port 33, the second chamber 52 communicates with the fourth connection port 34, and the third chamber 53 communicates with the fifth connection port 35. In the water supply device 8, the storage chamber 69 is located at the top among the first chamber 51, the second chamber 52, the third chamber 53, and the storage chamber 69.

[0098] The guide flow passage 70 is formed by penetrating a part of the third protruding portion 38 in the vertical direction. As a result, the guide flow passage 70 communicates with the third chamber 53 and the storage chamber 69. Unlike the water supply device 4, the guide flow passage 70 in this water supply device 8 is not provided with a mesh member 300. In addition, the guide flow passage 70 is formed smaller than the cartridge 61. Therefore, in the water supply device 8, the cartridge 61 in the storage chamber 69 does not fall through the guide flow passage 70 into the third chamber 53. Since each ceramic ball 60 is stored in the cartridge 61, each ceramic ball 60 does not fall through the guide flow passage 70 into the third chamber 53. In addition, the guide flow passage 70 is formed smaller than the guide flow passage 30 in the water supply device 4.

[0099] The supply port 71 is formed in the second peripheral wall 257 of the cover 25c. More specifically, the supply port 71 is formed in a position on the second peripheral wall 257 that will be the upper part of the storage chamber 69 when the cover 25c is attached to the housing body 25a. The supply port 71 penetrates the second peripheral wall 257 in the vertical direction and communicates with the storage chamber 69 from above. In this way, the supply port 71 opens toward the top of the housing 25 and communicates between the bathtub 1 and the storage chamber 69.

[0100] Here, the supply port 71 is formed to be slightly larger than the cartridge 61. This makes it possible to place the cartridge 61 in the storage chamber 69 or to remove the cartridge 61 from the storage chamber 69 through the supply port 71. At this time, the ceramic balls 60 are housed inside the cartridge 61. In other words, by placing the cartridge 61 in the storage chamber 69, the ceramic balls 60 can also be placed in the storage chamber 69.

[0101] Further, a first communication port 47 is formed in the second peripheral wall 257 of the cover 25b. The first communication port 47 is formed at a position opposite the supply port 71 in the circumferential direction of the second peripheral wall 257. The first communication port 47 penetrates the second peripheral wall 255 in the up-down direction, and communicates with the first chamber 51 from below.

[0102] In addition, in the second rear wall 256 of the cover 25b, in addition to the second communication port 48, a third communication port 49 is formed. The third communication port 49 is also an example of a "communication port" in the present invention. The second communication port 48 and the third communication port 49 each penetrate the second rear wall 256 in the front-rear direction. The second communication port 48 and the third communication port 49 are partitioned by the second protruding portion 37.

[0103] The second communication port 48 communicates with the second chamber 52 from the rear, and the third communication port 49 communicates with the third chamber 53 from the rear. As a result, the second communication port 48 and the third communication port 49 communicate the bathtub 1 with the second chamber 42 and the third chamber 43 in the front-rear direction. Here, the third communication port 49 is formed smaller than the third communication port 46 in the water supply device 4.

[0104] The nozzle 68 is disposed in the third chamber 53. As a result, the storage chamber 69 is located above the nozzle 68 within the housing 25. The nozzle 68 is connected to the other end of the fourth internal flow path 26d through the fifth connection port 35. The nozzle 68 has an injection hole 68a, and is capable of injecting water vapor that has flowed through the fourth internal flow path 26d from the injection hole 68a.

[0105] Injection hole 68a is formed at the rear end of nozzle 68. Injection hole 68a faces second rear wall 256 of cover 25c from the front within third chamber 53. In other words, injection hole 68a does not face directly into bathtub 1 via third communication port 49. Other configurations of the bathroom system of Example 2, including other components of water supply device 8, are similar to those of the bathroom system of Example 1, and the same components are denoted by the same reference numerals and detailed description of the configurations will be omitted.

[0106] In this bathroom system, as in the bathroom system of the first embodiment, the steam bath operation, combined operation, water filling operation, and reheating operation selected by the bather 10 through remote control 2 are carried out.

[0107] During steam bath operation, as shown in Fig. 12, in the water supply device 8, steam that has flowed through the second and fourth internal flow paths 26b and 26d is sprayed from the spray hole 68a of the nozzle 68. At this time, as shown by the dashed arrow in Fig. 12, in the water supply device 8, steam is sprayed from the spray hole 68a into the third chamber 53.

[0108] As a result, a portion of the water vapor in third chamber 53 flows through guide flow path 70 and reaches storage chamber 69. At this time, the water vapor that has flowed through guide flow path 70 passes through each vent hole 61a of cartridge 61, passing between each ceramic ball 60, into cartridge 61, and then into storage chamber 69. The water vapor in storage chamber 69 is then supplied into bathtub 1 from supply port 71.

[0109] Here, each ceramic ball 60 is also impregnated with essential oil. Therefore, in the water supply device 8, the relaxing fragrance components contained in the essential oil, i.e., functional components, are supplied into the bathtub 1 from the supply port 71 together with the water steam.

[0110] Meanwhile, the water vapor in third chamber 53 that has not passed through guide passage 70 is supplied into bathtub 1 from third communication port 49. For this reason, the water vapor supplied into bathtub 1 from third communication port 49 does not contain the functional component.

[0111] Here, in the water supply tool 8 as well, the position of the nozzle 68 in the third chamber 53, as well as the sizes of the guide passage 70, each vent 61a, the supply port 71, and the third communication port 49 are each designed so that the amount of water vapor supplied from the third communication port 49 into the bathtub 1 is greater than the amount of water vapor supplied from the supply port 71 into the bathtub 1. In particular, in the water supply path 8, the guide passage 70 is formed smaller than the guide passage 30 in the water supply tool 4, so that the flow rate of water vapor flowing from the third chamber 53 to the guide passage 70 is smaller. In this respect as well, in the water supply tool 8, the amount of water vapor supplied from the third communication port 49 into the bathtub 1 is greater.

[0112] Also, although not shown in the figure, during combined operation, water vapor is supplied into the bathtub 1 from the supply port 71 and the third communication port 49, and water that has flowed through the first internal flow path 26a and reached the first chamber 51 is supplied into the bathtub 1 from the first communication port 47.

[0113] Thus, in this bathroom system, the functional ingredients are supplied into the bathtub 1 together with water vapor from the supply port 71 of the water supply device 8, so that the bather 10 can effectively enjoy the effects of the functional ingredients while taking a steam bath using water vapor during steam bath operation or mixed operation.

[0114] Moreover, in water supply device 8, each ceramic ball 60 is housed in a cartridge 61. And, cartridge 61 can be placed in housing chamber 69 through supply port 71 with each ceramic ball 60 housed therein. For this reason, in this bathroom system, it is easier to replace or replenish each ceramic ball 60. Also, by housing each ceramic ball 60 in cartridge 61, there is no need to provide mesh member 300 in water supply device 4 to prevent each ceramic ball 60 from falling into guide flow path 70 or third chamber 43. Other functions of the bathroom system of embodiment 2, including the function of water supply device 8 during filling operation and reheating operation, are the same as those of the bathroom system of embodiment 1.

[0115] In addition, when the water in the bathtub 1 is stored beyond the water supply device 8, such as during filling operation and reheating operation, the cartridge 61 together with each ceramic ball 60 in the water supply device 8 can be removed in advance from the storage chamber 69.

[0116] In the above, the present invention has been described based on Examples 1 and 2. However, the present invention is not limited to the above Examples 1 and 2, and it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.

[0117] For example, the bathroom system of the first embodiment is capable of performing a steam bath operation, a combined operation, a water filling operation, and a reheating operation, but is not limited to these, and may be capable of performing only the steam bath operation. The same is true for the bathroom system of the second embodiment.

[0118] Furthermore, in the bathroom system of Example 1, housing body 25a of water supply device 4 is fixed to bathtub 1. However, this is not limited to the above, and the configuration may be such that housing body 25a is fixed to a wall surface of bathroom H, thereby supplying water vapor from supply port 39 into bathroom H. The same is true for the bathroom system of Example 2.

[0119] Furthermore, in the bathroom system of Example 1, water supply tool 4 may be provided with a lid that can open and close supply port 39. This makes it possible to prevent water from flowing into storage chamber 29 from supply port 39 by closing supply port 39 when steam is not being supplied from supply port 39. The same applies to the bathroom system of Example 2.

[0120] Furthermore, in the bathroom system of Example 1, the amount of water vapor supplied into the bathtub 1 from the third communication port 46 of the water supply device 4 is greater than the amount of water vapor supplied into the bathtub 1 from the supply port 39. However, this is not limited to the above, and the amount of water vapor supplied into the bathtub 1 from the supply port 39 may be greater than the amount of water vapor supplied into the bathtub 1 from the third communication port 46. Also, the amount of water vapor supplied into the bathtub 1 from the third communication port 46 may be equal to the amount of water vapor supplied into the bathtub 1 from the supply port 39. The same is true for the bathroom system of Example 2.

[0121] In the bathroom system of the first embodiment, the sponge 40 may be impregnated with an amino acid-based component or a hyaluronic acid-based component that has a skin maintenance effect. The same applies to the bathroom system of the second embodiment.
