[0003] Patent Literature

[0004] Patent Document 1: Japanese Patent Application Publication No. 2008-18130 Summary of the invention

[0005] However, in the bath sauna device shown in Patent Document 1, if a plurality of ultrasonic vibrators for generating mist are provided to increase the amount of mist generated, the heat generated by the oscillator for electrically oscillating the ultrasonic vibrator increases, causing the oscillator to malfunction.

[0006] In addition, in a water supply system that can supply both liquid water and mist, the user may think that the supply of liquid water and the supply of mist are related as water supply. Therefore, when the oscillator malfunctions and a problem occurs in the supply of mist, the user may feel uneasy about whether there is a problem with the supply of liquid water. Therefore, in a water supply system that can supply both liquid water and mist, a new problem arises: how to solve the problem of oscillator malfunction.

[0007] Therefore, the present invention is made to solve the problems of the above-mentioned prior art. The technical problem to be solved is to provide a water supply equipment system, which can suppress malfunction of the oscillator even when multiple ultrasonic vibrators are set to increase the water mist to be generated, and can suppress malfunction of the water supply equipment system that can supply both liquid water and mist.

[0008] In order to solve the above-mentioned problems, one embodiment of the present invention is a water supply equipment system that can supply both liquid water and mist, and is characterized in that it comprises: a water supply device that supplies liquid water; a water receiving part that receives water supplied from the water supply device; and a water mist supply device that supplies mist, comprising a water mist generating part that generates water mist and a water mist supply part that supplies the water mist generated by the water mist generating part, wherein the water mist generating part comprises: a water storage part that stores water for generating water mist; a plurality of ultrasonic vibrators that irradiate ultrasonic waves to water in the water storage part to generate water mist; and a plurality of oscillators, wherein one oscillator is connected to each of the plurality of ultrasonic vibrators in a group manner.

[0009] In one embodiment of the present invention thus constituted, the water mist generating unit comprises: a plurality of ultrasonic vibrators; and a plurality of the oscillators, one oscillator being connected to each of the plurality of ultrasonic vibrators in a group. Thus, in a water supply equipment system that can supply both liquid water and mist, even when a plurality of ultrasonic vibrators are provided to increase the amount of water mist to be generated, heat generation of each oscillator can be suppressed and malfunction of the oscillator can be suppressed, and malfunction of the water supply equipment system that can supply both liquid water and mist can be suppressed.

[0010] In one embodiment of the present invention, it is preferred that the water mist supply unit supplies the water mist generated by the water mist generating unit into a staying portion that forms a staying space that is open upward toward a room in which the water supply equipment system is used, and the water mist generating unit and the water mist supply unit are constructed so that the water mist supplied from the water mist supply unit stays in the staying space.

[0011] In one embodiment of the present invention constructed in this way, in order to make the water mist stay in a retention portion that forms a retention space open upward toward the room where the water supply equipment system is used, even when a plurality of ultrasonic vibrators are provided to increase the generated water mist, the heat generation of each oscillator can be suppressed and malfunction of the oscillator can be further suppressed, thereby further suppressing malfunction of the water supply equipment system that can supply both liquid water and mist.

[0012] In one embodiment of the present invention, preferably, the mist generating unit further includes a cooling device for cooling the oscillator.

[0013] In one embodiment of the present invention thus configured, the mist generating unit further includes a cooling device for cooling the oscillator. This allows the oscillator to dissipate heat more effectively, suppresses heat generation of the oscillator, and further suppresses malfunction of the oscillator.

[0014] In one embodiment of the present invention, the oscillator preferably comprises: an oscillator body; and a heat sink connected to the oscillator body in a manner to dissipate heat from the oscillator body, and the cooling device comprises a blower that forms an air flow reaching the heat sink.

[0015] In one embodiment of the present invention thus constructed, since the oscillator includes a heat sink, the oscillator body can be easily cooled, and since the cooling device includes a blower that sends air to the heat sink, the heat dissipation of the oscillator body can be further promoted. Thus, the oscillator is cooled more effectively, the heat generation of the oscillator is suppressed, and the malfunction of the oscillator can be further suppressed.

[0016] In one embodiment of the present invention, preferably, the cooling device further includes a cooling flow path extending from an air intake port to an air exhaust port and allowing the air flow generated by the blower to pass therethrough, and the radiator is configured to have a portion exposed to the cooling flow path.

[0017] In one embodiment of the present invention thus constructed, the heat sink is configured to have a portion exposed to a cooling flow path through which an air flow generated by a blower passes. Thus, the heat sink can be effectively cooled by the air flow, and the heat dissipation of the oscillator body by the heat sink can be further promoted. Thus, the heat dissipation of the oscillator is more effectively performed, the heat generation of the oscillator is suppressed, and the malfunction of the oscillator can be further suppressed.

[0018] In one embodiment of the present invention, preferably, when viewed from the upstream side of the cooling flow path, the plurality of heat sinks are arranged to be divided into at least a first region in the cooling flow path and a second region offset from the first region in the cooling flow path.

[0019] In one embodiment of the present invention thus constituted, when viewed from the upstream side of the cooling flow path, the plurality of heat sinks are arranged to be divided into at least a first region in the cooling flow path and a second region in the cooling flow path that is offset from the first region. Thus, compared with a case where the plurality of heat sinks are arranged in series in only one region when viewed from the upstream side of the cooling flow path, it is possible to suppress the temperature rise of the air reaching the heat sink disposed on the downstream side of the cooling flow path among the plurality of heat sinks, cool the plurality of heat sinks by an air flow with a small air volume, suppress the heat generation of the oscillator, and further suppress the malfunction of the oscillator.

[0020] In one embodiment of the present invention, it is preferred that the water supply equipment system can supply both liquid water and mist water into the bathroom.

[0021] In one embodiment of the present invention thus constructed, the water supply equipment system can supply both liquid water and mist water mist into the bathroom. Thus, in the bathroom system that can supply both liquid water and mist water mist into the bathroom, even when a plurality of ultrasonic vibrators are provided to increase the amount of water mist to be generated, the heat generation of each oscillator can be suppressed and malfunction of the oscillator can be suppressed, and malfunction of the bathroom system that can supply both liquid water and mist water mist can be further suppressed.

[0022] In one embodiment of the present invention, it is preferred that at least a portion of the cooling flow path of the cooling device is formed in the bathroom, the air intake port of the cooling flow path is formed in a manner opening toward the outside of the bathroom, and the air exhaust port of the cooling flow path is also formed in a manner opening toward the outside of the bathroom.

[0023] In one embodiment of the present invention thus constituted, even when at least a portion of the cooling flow path of the cooling device is formed in the bathroom, the air intake port of the cooling flow path is formed in a manner that opens toward the outside of the bathroom, and the air exhaust port of the cooling flow path is formed in a manner that opens toward the outside of the bathroom. Thus, it is possible to prevent the high-temperature and humid air in the bathroom from flowing into the cooling flow path from the air intake port, and it is possible to prevent the high-temperature and humid air from being supplied to the oscillator in the cooling flow path, causing the oscillator to short-circuit or the oscillator to have insufficient heat dissipation, and to prevent the oscillator from malfunctioning. In addition, since at least a portion of the cooling flow path of the cooling device is formed in the bathroom, the cooling flow path of the water supply equipment system can be relatively easily configured from the bathroom, compared with the case where the cooling flow path is completely configured outside the bathroom, and the construction of the water supply equipment system can be further simplified. Therefore, according to one embodiment of the present invention, the water supply equipment system can be constructed more simply from the bathroom, and it is also possible to prevent the oscillator from malfunctioning due to the high-temperature and humid air in the bathroom.

[0024] In one embodiment of the present invention, preferably, the cooling device further includes a circulation suppressing unit configured to prevent the air flow exhausted from the exhaust port from returning to the intake port.

[0025] In one embodiment of the present invention thus constructed, the cooling device further includes a circulation suppression unit, which is formed so that the air flow discharged from the exhaust port is difficult to return to the air intake port. Thus, it is possible to make it difficult for the air heated by the waste heat of the oscillator to circulate from the exhaust port to the air intake port, which can suppress poor heat dissipation of the oscillator and further suppress poor operation of the oscillator.

[0026] In one embodiment of the present invention, it is preferable that the circulation suppression means includes an air direction control unit that suppresses the formation of an air flow that flows linearly from the exhaust port toward the intake port.

[0027] In one embodiment of the present invention thus constructed, the circulation suppression unit includes a wind direction control unit that suppresses the formation of an air flow that flows linearly from the exhaust port toward the air intake port. This makes it more difficult for the air heated by the waste heat of the oscillator to circulate from the exhaust port to the air intake port, and can further suppress poor heat dissipation of the oscillator and poor operation of the oscillator.

[0028] In one embodiment of the present invention, it is preferable that the wind direction control unit is formed by a wall portion protruding outward from the outside of the bathroom at the air inlet or the air outlet.

[0029] In one embodiment of the present invention thus constituted, the wind direction control unit is formed by a wall portion protruding outward from the outside of the bathroom at the air inlet or the air outlet. Thus, with a relatively simple structure, it is possible to make it difficult for air to circulate from the air outlet to the air inlet.

[0030] In one embodiment of the present invention, it is preferable that the wall portion of the wind direction control portion is formed of a tube wall portion formed by cutting out a part of a tube wall.

[0031] In one embodiment of the present invention thus constructed, the wall portion of the wind direction control portion is formed by a tube wall portion, and the tube wall portion is formed by cutting a portion of the tube wall. Thus, with a relatively simple structure, the wall portion can be formed by a tube, which can make it difficult for air to circulate from the exhaust port to the intake port.

[0032] According to the water supply system of the present invention, it is possible to suppress malfunction of the water supply system which can supply both liquid water and mist water. BRIEF DESCRIPTION OF THE DRAWINGS

From the following description, it is obvious that more improvements or other embodiments can be made to those skilled in the art. Thus, the following description should be interpreted as merely illustrative and is provided for the purpose of showing the best form for performing the present invention to those skilled in the art. Without departing from the purpose of the present invention, the details of its structure and / or function can be substantially changed.

[0060] Below, refer to Figure 1 and Figure 2 A water supply equipment system according to a first embodiment of the present invention will be described.

[0061] Figure 1 is a perspective view of a water supply system according to a first embodiment of the present invention. Figure 2 It is a cross-sectional view for explaining the structure of the water supply equipment system according to the first embodiment of the present invention.

[0062] The water supply equipment system 1 is a water supply equipment system that can supply both liquid water and mist water. The water supply equipment system 1 is installed in the bathroom 3. The water supply equipment system 1 is a bathroom system that can supply both liquid water and mist water into the bathroom 3.

[0064] The water supply device 2 includes at least one of a bathtub water supply device 6 for supplying water to a bathtub body 12, a wash area side faucet device 8 for supplying water to the floor side of a wash area body 18 of a bathroom, or a shower faucet device 10 for supplying water from a shower head. Furthermore, the water supply device 2 may also include multiple or all of the bathtub water supply device 6, the wash area side faucet device 8, and the shower faucet device 10. In addition, as long as it is a water supply device for supplying liquid water to the bathroom 3, the water supply device 2 may also be a water supply device of other types. Regardless of the temperature, water also includes water having a temperature higher than the external air temperature (normal temperature) and heated water (so-called hot water). That is, the water supply device 2 also includes a water supply device for supplying hot water.

[0065] The bathtub water supply device 6 is provided in the bathtub body 12. The bathtub water supply device 6 includes a supply device 14 for supplying water, and water from a cold water supply pipe 16 connected to a water supply source such as a tap and / or a hot water supply pipe 17 for supplying hot water from a hot water supply machine is supplied to the bathtub body 12 through the supply device 14 receiving a command from the control unit. Therefore, the bathtub water supply device 6 is configured to supply water to the bathtub body 12 in the bathroom at any time. The supply device 14 can be provided in the bathroom 3, for example, it can also be provided in the water mist supply device 4.

[0066] The washing area side faucet device 8 is installed on a wall portion of a table or the like on the washing area main body 18 side of the bathroom 3. The washing area side faucet device 8 includes a supply device 14 for supplying water, and supplies water from a cold water supply pipe 16 connected to a water supply source such as a tap and / or a hot water supply pipe 17 that supplies hot water from a hot water supply machine to the washing area main body 18 through the supply device 14 that receives a command from the control unit. Therefore, the washing area side faucet device 8 is configured to supply water to the washing area main body 18 in the bathroom at any time.

[0067] The shower faucet device 10 is provided on a wall portion of the bathroom 3. The shower faucet device 10 includes a supply device 14 for supplying water, and supplies water from a cold water supply pipe 16 connected to a water supply source such as a tap and / or a hot water supply pipe 17 that supplies hot water from a hot water supply machine to a washing area body 18 through the supply device 14 that receives a command from a control unit. Therefore, the shower faucet device 10 is configured to supply water to the bathtub body 12 or the washing area body 18 in the bathroom at any time.

[0068] The bathtub body 12 is a bathtub (bathtub) and can store water in the retention space 20 inside. The bathtub body 12 constitutes a water receiving portion for receiving water supplied from the bathtub water supply device 6 or the shower faucet device 10. The bathtub body 12 is also a retention portion for retaining water mist. The bathtub body 12 forms a retention space 20 that is open upward toward the indoor space 5 in the bathroom 3. When viewed from above, the bathtub body 12 is formed in a rectangular shape, and a long side portion 12d is formed on the long side of the rectangle, and a short side portion 12e is formed on the short side. The short side portion 12e is shorter in width than the long side portion 12d.

[0069] The retention space 20 is a space formed in a substantially rectangular parallelepiped shape inside the bath body 12. Figure 2 As shown, when user A takes a bath, water B at 34°C to 45°C is stored in the lower part of the stay space 20, and user A can take a bath while sitting. Figure 2In the state where water mist stays above the water B in the staying space 20 (a state where a staying layer C of water mist is formed). The staying space 20 is formed to the upper end portion 12a of the bathtub body 12, and the top surface side is opened. In a state where a cover such as covering the top surface of the staying space 20 is omitted, as described later, the water mist stays in the staying space 20 of the bathtub body 12. In addition, the staying space 20 may not store water B but allow the water mist to stay. The shape of the bathtub body 12 is not limited to a box shape as in the embodiment, as long as the shape of the staying space can be formed. For example, when viewed from above, the bathtub body 12 may also be formed in a circular or elliptical shape, with a basin-shaped staying space formed inside. The bottom surface of the bathtub body 12 may also be formed obliquely so that the user can take a posture close to a lying bathing posture or a sitting posture, and a step portion may be formed on the bottom surface or not formed. The top edge portion of the wall portion of the bathtub body 12 may also be formed to change in height, rather than being formed horizontally at a constant height. For example, when viewed from the side, the long side of the wall of the bath body 12 may extend obliquely upward or downward, or may extend in a partially downwardly concave bow shape, or may be substantially at a right angle.

[0070] The washing area body 18 forms a retention space 120 on the washing area body side that is open to the indoor space 5 in the bathroom 3. The washing area body 18 is formed by the washing area floor, the wall surface of the bathroom, the outer wall of the bathtub body, the door of the bathroom, etc., and water can flow in the inner retention space 120. The washing area body 18 constitutes a water receiving part that receives water supplied from the washing area side faucet device 8 or the shower faucet device 10. With such a structure, the washing area body 18 allows the water mist to stay in the retention space 120.

[0071] The mist supply device 4 includes a mist generating unit 22 for generating mist and a mist supply unit 24 for supplying the mist generated by the mist generating unit 22 into the bathtub body 12. The mist supply device 4 is attached to the wall W.

[0072] The mist generating unit 22 generates mist from water. The water may be heated water whose water temperature is controlled, or may be unheated water, for example, water supplied from a water supply source such as a water pipe. The mist generating unit 22 may generate mist whose temperature is controlled by heating the mist generated from water. The mist generating unit 22 is disposed above the short side portion 12e of the short side of the bathtub body 12.

[0073] The water mist generating section 22 comprises: a water storage section 26 for storing water for generating water mist; a water supply passage 29 for supplying water from a water supply source to the water storage section 26; a drainage passage 30 for discharging water from the water storage section 26 to a drainage pipe; an ultrasonic vibrator 32 arranged at the bottom of the inner side of the water storage section 26; a water temperature detecting unit, i.e., a water temperature measuring device 34, arranged on the inner side of the water storage section 26; an air temperature detecting unit, i.e., an indoor temperature measuring device 36, arranged on the outer side of the water storage section 26; an oscillator 38 for causing the ultrasonic vibrator 32 to generate a specified electrical oscillation; and a control section 40 for controlling the ultrasonic vibrator 32.

[0074] The water storage section 26 is formed in a rectangular parallelepiped shape. A water supply passage 29 and a drainage passage 30 are connected to the side wall at the lower part of the water storage section 26. A water mist supply section 24 is connected to the side wall near the center of the water storage section 26. A water supply passage opening and closing valve 27 for opening and closing the water supply passage 29 is provided on the water supply passage 29. A drainage passage opening and closing valve 31 for opening and closing the drainage passage 30 is provided on the drainage passage 30.

[0075] The ultrasonic vibrator 32 irradiates (oscillates) ultrasonic waves to the water in the water storage section 26, thereby vibrating the water on the liquid surface in the water storage section 26, and the water is made into particles from the liquid surface, thereby generating water mist (fog) of a predetermined particle size. The ultrasonic vibrator 32 is electrically connected to the oscillator 38, and the particle size of the generated water mist can be changed by adjusting the oscillation output and frequency of the ultrasonic wave of the ultrasonic vibrator 32. The water mist generating section 22 and the water mist supplying section 24 are configured such that the main particle size (for example, more than half of the particle size) of the water mist supplied from the water mist supplying section 24 is 3.1 μm or more and 40 μm or less, more preferably 3.6 μm or more and 20 μm or less, and further preferably 4.1 μm or more and 10 μm or less.

[0076] A plurality of ultrasonic vibrators 32 are provided in the water storage portion 26. The plurality of ultrasonic vibrators 32 are arranged in a row parallel to the wall W in the water storage portion 26. For example, Figure 2 and Fig.11 As shown, eight ultrasonic vibrators 32 are arranged in one row parallel to the wall W. The ultrasonic vibrators 32 may be arranged in a plurality of rows parallel to the wall W. In addition, the ultrasonic vibrators 32 may be arranged in the water storage portion 26 in other ways than in rows.

[0077] The water temperature measuring device 34 detects the water temperature in the water storage portion 26. The control unit 40 is electrically connected to the water temperature measuring device 34, and the control unit 40 can recognize the water temperature in the water storage portion 26 measured by the water temperature measuring device 34.

[0078] The indoor temperature measuring device 36 detects the air temperature of the indoor space 5 in which the bathtub body 12 is disposed. The control unit 40 is electrically connected to the indoor temperature measuring device 36, and the control unit 40 can recognize the air temperature of the indoor space 5 measured by the indoor temperature measuring device 36. In addition, in the state before the water mist supply starts (before the water mist generating unit 22 is driven), since it is assumed that the air temperature of the indoor space 5 and the air temperature in the staying space 20 are substantially equal to or relatively close to each other, the control unit 40 can infer the air temperature of the indoor space 5 measured by the indoor temperature measuring device 36 as the air temperature in the staying space 20.

[0079] The mist supply unit 24 supplies the mist generated by the mist generating unit 22 to the retention unit, that is, the bath body 12, which forms a retention space 20 that is open upward toward the room where the water supply equipment system 1 is used. Figure 2 As shown in the flow path cross section, the water mist supply part 24 forms a flow path extending from the water mist generating part 22 to the upper part of one end of the retention space 20. When viewed from the front (from the retention space 20 side), the opening of the water mist supply part 24 is formed in a horizontally long rectangular shape along the short side portion 12e of the bathtub body 12. The water mist supply part 24 is arranged at a position closer to the top than the overflow part 12c of the water in the bathtub body 12. In the present embodiment, the overflow part 12c is the overflow surface 12b of the bathtub body 12. As a modified example, the overflow part 12c can also be an overflow port provided in the bathtub body 12. In addition, the water mist supply part 24 is arranged above the short side portion 12e of the short side of the bathtub body 12.

[0080] The mist supply unit 24 includes a mist supply passage 24a extending laterally from the mist generating unit 22 to the upper portion of one end of the retention space 20, and a mist supply port 24b connected to the downstream end of the mist supply passage 24a and opening downward. The mist supply passage 24a and the mist supply port 24b form a pipe-shaped passage. The mist supply port 24b is located above the retention space 20 closer to the inner side of the bathtub body 12 than the short side portion 12e.

[0081] The mist generating unit 22 and the mist supplying unit 24 control the temperature of the mist while generating the mist so that the mist easily stays in the staying space 20. The mist generating unit 22 and the mist supplying unit 24 are configured so that the temperature difference between the temperature of the mist supplied from the mist supplying unit 24 to the staying space 20 and the temperature of the indoor space 5 used by the water supply equipment system 1 before the start of the mist supply becomes 0°C or more, and the mist supplied from the mist supplying unit 24 stays in the staying space 20 of the bathtub body 12. In addition, the mist generating unit 22 and the mist supplying unit 24 of the mist supplying device 4 are configured so that the rising airflow formed by the temperature difference between the temperature of the mist and the temperature of the indoor space 5 forms a temperature difference in such a way that the force of the mist rising does not exceed the weight of the mist corresponding to the particle size of the mist supplied from the mist supplying unit 24. It is also possible to achieve such water mist supply without using the indoor temperature measuring device 36 (not relying on the measurement result of the indoor temperature measuring device 36) by presetting the water temperature in the water mist generating unit 22 or the frequency of the ultrasonic vibrator 32 according to the air temperature range of the indoor space 5 to be assumed. In addition, it is also possible to achieve such water mist supply by adjusting the setting when supplying water mist. The water mist generating unit 22 and the water mist supplying unit 24 are configured so that the temperature difference is preferably 100°C or less, more preferably 60°C or less, and further preferably 45°C or less. The water mist generating unit 22 and the water mist supplying unit 24 control the temperature of the water mist and the particle size of the water mist so that the water mist is easy to stay in the staying space 20. Moreover, even when the temperature of the water mist supplied by the water mist generating unit 22 and the water mist supplying unit 24 is the same as the temperature of the indoor space 5 or lower than the temperature of the indoor space 5, it is difficult to form an upward airflow that exceeds the weight of the water mist by the temperature of the water mist, and the water mist can be kept in the staying space 20.

[0082] In addition, the water mist generating unit 22 and the water mist supplying unit 24 set the supply amount per unit volume to be, for example, within the range of 0.03 mL / min·L to 1.5 mL / min·L. The water mist generating unit 22 and the water mist supplying unit 24 can, for example, supply water mist at a supply amount of 11 mL / min per unit time to a residence space of a volume of 330 L of the bathtub body 12. In addition, for example, the water mist generating unit 22 and the water mist supplying unit 24 can supply water mist at a supply amount of 6 mL / min per unit time to a residence space of a volume of 4.32 L of other water-using equipment, etc. The supply amount of water mist can be controlled by the number and output of the ultrasonic vibrators 32, the irradiation direction of the ultrasonic wave, the water level in the water mist generating unit 22, or the flow path shape in the water mist generating unit 22 or the water mist supplying unit 24, etc.

[0083] Furthermore, in order to generate water mist with controlled temperature, the water mist generating unit 22 may further include a heater (not shown) inside the water storage unit 26. The heater is electrically connected to the control unit 40, and has, for example, a function of heating the water in the water storage unit 26, and also has a function of controlling the water temperature in the water storage unit 26. For example, the heater can heat water at a supply water temperature (for example, room temperature of about 20°C) to a temperature of 60°C or higher than room temperature. In addition, for example, once the water is heated to 60°C or higher by the heater, the control unit 40 can perform temperature control to increase or decrease in such a manner that the temperature difference described later becomes 0°C or higher. The water mist generating unit 22 may be configured to omit such a heater. For example, the water mist generating unit 22 may omit such a heater, and heat the water to 60°C or higher in the hot water supply unit, and on this basis, generate water mist from the water supplied to the water mist generating unit 22. By heating the water to 60°C or higher, the reproduction of at least some bacteria (for example, Legionella) can be suppressed. The water mist generating unit 22 can generate water mist even if the heater is omitted.

[0084] The control unit 40 has a built-in CPU and memory, etc., and controls the connected devices in a manner of executing the generation of water mist according to a predetermined control program stored in the memory, etc. The control unit 40 is electrically connected to the oscillator 38, the water temperature measuring device 34, the indoor temperature measuring device 36, the operation unit 28, the air blower 48, etc. The control unit 40 is also electrically connected to the water supply passage opening and closing valve 27 provided on the water supply passage 29 and the drainage passage opening and closing valve 31 provided on the drainage passage, and can control these.

[0085] Returning to this embodiment, by Figures 3 to 14 The oscillator 38 and the cooling device 42 of the water mist generating unit 22 will be described in more detail.

[0086] A plurality of oscillators 38 are provided in the cooling device 42. The oscillators 38 are arranged along the cooling flow path 50 (see, for example, Figure 8 ) are arranged in a row parallel to the wall W. The oscillators 38 are arranged in a row of four in series on the upper side of the cooling flow path 50, and are arranged in a row of four in series on the lower side of the cooling flow path 50, with a total of eight oscillators being provided. Fig.11 As shown, the oscillator bodies 44 of the oscillators 38 are independently connected to power supplies 60. The power supply 60 is a power supply source such as a socket, a battery, etc. In addition, the oscillator bodies 44 of the oscillators 38 can also be electrically connected to the oscillator bodies 44 of other oscillators 38.

[0087] The oscillator 38 includes: an oscillator body 44; and a heat sink 46 connected to the oscillator body 44 in a manner to dissipate heat from the oscillator body 44. The oscillator body 44 is formed as a plate-shaped component. A circuit for realizing the function of the oscillator 38 is arranged on the oscillator body 44. The oscillator body 44 has a circuit structure that can oscillate electricity of a high-frequency voltage such as 2.4 MHz. The oscillator body 44 is electrically connected to the control unit 40. The oscillator body 44 sometimes generates heat in the circuit. A portion of the oscillator body 44 is in a cooling device internal space 51 (see FIG. 5 ) in a cooling device 42 that is different from the cooling flow path 50. Figure 8 ) is exposed. The cooling device internal space 51 in the cooling device 42 is divided from the high-temperature and high-humidity indoor space 5 in the bathroom 3. Since the cooling device internal space 51 is formed so that the high-temperature and high-humidity air of the indoor space 5 is difficult to flow into, it is possible to suppress the malfunction of the electrical component, namely the oscillator body 44. The oscillator body 44 is connected to the heat sink 46 by a metal with relatively low thermal resistance or a ceramic component with relatively high thermal conductivity. In the oscillator body 44, in particular, a metal with relatively low thermal resistance extends from the connection part of the heat sink 46 to the substrate on which the circuit is configured. In addition, in the oscillator body 44, the heat sink 46 and the substrate on which the circuit is configured can also be directly connected.

[0088] like Fig.11 As shown, the oscillator 38 is as follows, and one oscillator 38 is connected to each ultrasonic vibrator 32 among the plurality of ultrasonic vibrators 32 in a group manner (a group of a single ultrasonic vibrator 32 and a single oscillator 38). One group of one ultrasonic vibrator 32 and one oscillator 38 is formed, for example, to use a high-frequency output of 50 W or less. The configuration of the combination of the oscillator body 44 and the ultrasonic vibrator 32 can be freely configured, for example, one oscillator body 44 and a plurality of ultrasonic vibrators 32 can be formed into one group, and each group can be independently connected to the power supply 60.

[0089] The oscillator 38 and the ultrasonic vibrator 32 are connected by a high-frequency cable 33 that can transmit high-frequency electricity such as 2.4 MHz. The length of the high-frequency cable 33 is a length that maintains sufficient electrical transmission performance for transmitting high-frequency electricity such as 2.4 MHz. Generally speaking, the shorter the length of the high-frequency cable 33, the more efficiently it can transmit electricity. Therefore, the length from each ultrasonic vibrator 32 to each oscillator 38 via the high-frequency cable 33 is restricted to a shorter length. The ultrasonic vibrator 32 is arranged in the bathroom 3, so in order to improve maintainability and construction, etc., it is preferred that the oscillator 38 is also arranged in the bathroom 3. In addition, in the bathroom 3, the cooling device 42 of the water mist generating part 22 is formed by a structurally connected integral structure (in the present embodiment, it is an integral box shape) with the water storage part 26 and the water mist supply part 24.

[0090] The heat sink 46 is arranged in the cooling flow path 50 so as to have a portion exposed to the cooling flow path 50. The heat sink 46 includes a plurality of heat sinks 46a formed of a metal such as aluminum. The heat sinks 46a of the heat sink 46 are arranged so as to be exposed to the cooling flow path 50. The heat sinks 46a of the heat sink 46 are arranged with respect to the flow direction G in the cooling flow path 50 (refer to Figure 7 and Fig.10 ) and a plurality of heat sinks 46a are arranged in parallel up and down. The root 46b (refer to Figure 8 and Figure 5 ) is connected to the oscillator body 44.

[0091] When viewing the downstream side from the upstream side of the cooling flow path 50 or viewing the downstream side from the middle portion of the cooling flow path 50, the plurality of heat sinks 46 are arranged to be distributed in at least a first region R1 (see FIG. 1 ) in the cooling flow path 50. Figure 8 ) and a second region R2 offset from the first region R1 in the cooling flow path 50. Although the first region R1 and the second region R2 are mainly located in different regions, they may overlap in part. For example, the first region R1 is a part of the upper region on the upper side of the cooling flow path 50, and the second region R2 is a part of the lower region on the lower side of the cooling flow path 50. In the first region R1 of the cooling flow path 50, the radiator 46 is disposed along the inner wall 50a (see Figure 8 and Fig.10 ) are arranged in series. In addition, in the second region R2 of the cooling flow path 50, four heat sinks 46 are arranged in series along the inner wall 50a of the cooling flow path 50. In addition, as Figure 8 As shown, when the downstream side is viewed from the upstream side (or the middle part) of the cooling flow path 50, one radiator 46 is arranged in parallel up and down in each of the first region R1 and the second region R2. In addition, the radiators 46 (oscillators 38) do not necessarily need to be arranged in parallel up and down, for example, the radiator 46 of the upper section is close to the wall side and the radiator 46 of the lower section is close to the indoor side, etc., and can also be staggered in the wall side direction. In addition, the radiator 46 of the upper section is close to the upstream side of the cooling flow path 50 and the radiator 46 of the lower section is close to the downstream side of the cooling flow path 50, and the upper section and the lower section can also be staggered. In addition, the radiator 46 (oscillator 38) is not necessarily in two rows of the upper section and the lower section, but can also be in three rows of the upper section, the middle section, and the lower section. In addition, the radiators 46 are not necessarily evenly distributed, but can be freely arranged by disposing 4 in the upper section, 3 in the lower section, and 1 in the middle section area on the downstream side of these, etc.

[0092] The mist generating unit 22 further includes a cooling device 42 for cooling the oscillator 38. The cooling device 42 includes: a blower 48 for forming an air flow to reach the radiator 46; a cooling flow path 50 extending from the air intake port 52 to the exhaust port 54 and allowing the air flow generated by the blower 48 to pass through; and a circulation suppression unit 56 formed so that the air flow discharged from the exhaust port 54 is difficult to return to the air intake port 52.

[0093] The blower 48 is formed to send the air flowing in from the air inlet 52 to the exhaust port 54. The blower 48 forms an air flow in a direction parallel to the extension direction of the cooling flow path 50. The blower 48 includes: blades (not shown) for sending out air; and an electric drive unit (not shown) for rotating the blades. The blower 48 is formed by, for example, a fan that generates wind. The blower 48 is driven by receiving a command from the control unit 40. The blower 48 forcibly sends air to the radiator 46, thereby improving the cooling capacity compared to natural air cooling. Although the cooling device 42 in the present embodiment adopts a forced air cooling method using the blower 48, a natural air cooling method in which the blower 48 is omitted can also be adopted, or a water cooling method in which water is used to dissipate heat from the radiator 46 can also be adopted. In addition, although the blower 48 is arranged on the upstream side of the cooling flow path 50, it can also be arranged on the downstream side. In addition, although the blower 48 is provided to generate an air flow toward the heat sink 46 in the cooling flow path 50 , it may also be provided to generate an air flow toward the oscillator body 44 .

[0094] At least a portion of the cooling flow path 50 of the cooling device 42 is formed in the bathroom 3. The cooling flow path 50 forms an air flow path in the bathroom 3 that is separated from the indoor space 5. The cooling flow path 50 forms a pipe-like flow path from the air intake port 52 to the air exhaust port 54. Since the cooling flow path 50 is formed so that high-temperature and humid air generated from the bathtub in the indoor space 5 is difficult to flow into, it is possible to suppress a decrease in the cooling efficiency in the cooling flow path 50. The cooling flow path 50 is formed in a space in which two radiators 46 can be arranged in parallel vertically. Figure 8As shown in the figure, for example, the cooling flow path 50 forms a flow path cross section of a square shape, and one longitudinal side of the cooling flow path 50 in the vertical direction is formed to be approximately half of the height of the heat sink 46, and one lateral side in the left-right direction is formed to be approximately one-half of the width of the heat sink 46. Therefore, in the area where the heat sink 46 is arranged in the cooling flow path 50, the heat sink 46 is arranged to occupy more than half of the area in the cooling flow path 50, and the cooling efficiency of the heat sink 46 is improved. Since the cooling flow path 50 is also divided from the internal space 51 of the cooling device, it is possible to suppress the air flow flowing through the cooling flow path 50 from being disturbed by the unevenness of the circuit elements of the oscillator body 44, and thus it is possible to suppress the cooling efficiency from being reduced due to the pressure loss of the air flow. That is, since the heat sink 46 is mainly arranged in the cooling flow path 50, the unevenness of the circuit elements of the oscillator body 44 is not formed inside, and thus it is possible to suppress the cooling efficiency from being reduced due to the pressure loss of the air flow, and the cooling efficiency is improved. Furthermore, the oscillator body 44 may be configured such that the circuit elements of the oscillator body 44 are arranged in the cooling flow path 50 .

[0095] The air inlet 52 of the cooling flow path 50 is formed to open to the outside of the bathroom 3, and the air outlet 54 of the cooling flow path 50 is also formed to open to the outside of the bathroom 3. The air inlet 52 forms a circular opening and extends from the outside to the inside of the bathroom 3. The air outlet 54 forms a circular opening and extends from the inside to the outside of the bathroom 3.

[0096] like Figure 4 As shown in FIG. 1 , the circulation suppression unit 56 includes a wind direction control unit 62 that suppresses the formation of a straight air flow from the exhaust port 54 toward the intake port 52. The wind direction control unit 62 is formed by a wall protruding from the outside 3a of the bathroom 3 at the intake port 52 or the exhaust port 54.

[0097] The wind direction control unit 62 is formed as a tube wall portion, which is formed by cutting a portion of the tube wall of the tube protruding outward from the outside 3a of the bathroom 3 at the air inlet 52 and / or the air outlet 54. The tube also includes tubes other than circular tubes. The wind direction control unit 62 is formed by an arc-shaped wall portion at the air inlet 52 and / or the air outlet 54. In this way, the wind direction control unit 62 can also be arranged only at either the air inlet 52 or the air outlet 54.

[0098] When the air intake port 52 is observed from the front, the wind direction control portion 62 is formed in a C-shape by cutting the arc portion of the entire circumference of the circular tube in an angle range equivalent to 90 degrees, and an opening portion 62a is formed that opens in the direction toward the outside 3a. The opening portion 62a of the wind direction control portion 62 opens at the air intake port 52 toward the opposite side of the exhaust port 54. In addition, the opening portion 62a of the wind direction control portion 62 opens at the exhaust port 54 toward the opposite side of the air intake port 52. The wind direction control portion 62 is configured to suppress the formation of an air flow that flows in a straight line from the exhaust port 54 toward the air intake port 52. In addition, the wind direction control portion 62 can suppress the formation of an air flow that flows out from the exhaust port 54 to the air intake port 52 at the exhaust port 54, and can suppress the formation of an air flow that flows in from the exhaust port 54 to the air intake port 52 at the air intake port 52. The wind direction control portion 62 can also be a flat wall. In addition, the wind direction control unit 62 can also be formed by a partition-shaped wall or protrusion arranged at the position of the exhaust port 54 and / or the air inlet 52. In addition, the opening portion 62a does not necessarily need to be opened toward the opposite side of the air inlet 52 or the exhaust port 54, but it is sufficient to be opened in a direction in which it is difficult for an air flow to flow from the exhaust port 54 to the air inlet 52. In addition, the circulation suppression unit 56 can also be formed by a partition-shaped wall or protrusion arranged at a position on a straight line connecting the air inlet 52 and the exhaust port 54, so as to suppress the formation of an air flow that flows in a straight line from the exhaust port 54 to the air inlet 52. In addition, the wind direction control unit 62 can also be formed so that the direction in which the exhaust port 54 and / or the air inlet 52 is opened is different from the direction from the exhaust port 54 to the air inlet 52, so as to suppress the formation of an air flow that flows in a straight line from the exhaust port 54 to the air inlet 52. For example, the wind direction control unit 62 may be formed by an L-shaped pipe extending outward from the outside of the bathroom 3, the exhaust port 54 may be opened toward the opposite side of the air inlet 52, and the air inlet 52 may be opened toward the opposite side of the exhaust port 54. That is, the wind direction control unit 62 may not be formed in a manner that cuts a portion of the pipe wall. In addition, the exhaust port 54 and / or the air inlet 52 may be formed in a manner that is inclined relative to the wall W so that the direction of the opening of the exhaust port 54 and / or the air inlet 52 is different from the direction from the exhaust port 54 to the air inlet 52. As long as the direction of the opening of the wind direction control unit 62 is different, it is not necessary to form a wall portion that protrudes outward from the outside 3a.

[0099] Furthermore, as a modified example, the wind direction control unit 62 may be formed so that the air flowing out from the exhaust port 54 toward the air inlet 52 side is difficult to flow toward the air inlet 52. For example, the wind direction control unit 62 may be formed so that the air flowing out from the exhaust port 54 in a direction inclined to the straight line connecting the exhaust port 54 and the air inlet 52 is suppressed and flows toward the air inlet 52 by detouring the straight line.

[0100] When a bathroom 3 is provided in a building, it is generally known that the bathroom 3 where air containing high-temperature and high-humidity air may be generated is provided inside a room formed by the structural outer wall 9 of the building (including the structural wall inside the building). In this case, in order to ensure space for other rooms or to effectively arrange the bathroom 3, the gap D (see FIG. 1 ) between the structural outer wall 9 of the building and the bathroom 3 is generally 1 / 4 of the gap D. Fig.12 ) is a relatively narrow gap of about several centimeters. As such, when the gap D between the outer wall 9 and the bathroom 3 is small, the space for air flow is limited, and the air is easily flowing from the exhaust port 54 to the air intake port 52. Therefore, suppressing the formation of a straight air flow from the exhaust port 54 toward the air intake port 52 by the wind direction control unit 62 is particularly effective in suppressing the recirculation of the heated air.

[0101] like Fig.13 As shown in FIG. 1 , as a modified example, when the air inlet 52 is viewed from the front, the wind direction control portion 62 may be formed in a C-shape by cutting a circular arc portion of the entire circumference of the circular tube corresponding to an angle range of 180 degrees, and an opening portion 62a is formed that opens in the direction toward the outer surface 3a. Fig.14 As shown in FIG. 1 , as another modification, when the air inlet 52 is viewed from the front, the wind direction control portion 62 may be formed in a C-shape by cutting an arc portion of an angle range equivalent to 270 degrees in the entire circumference of the circular tube, and an opening portion 62a is formed that opens in the direction toward the outside 3a. In this way, the wind direction control portion 62 may be formed by an arc portion of any angle range, and the size, length, etc. may be changed.

[0102] Furthermore, as another modified example, the cooling flow path 50 of the cooling device 42 may be formed in a manner extending in the longitudinal direction so that the air intake port 52 and the air exhaust port 54 of the cooling flow path 50 of the cooling device 42 are arranged in the longitudinal direction. In this case, for example, the air intake port 52 is arranged at the lower part, and the air exhaust port 54 is arranged at a position closer to the upper part than the air intake port 52. If arranged in this way, the heated air discharged from the air exhaust port 54 is easy to form an upward airflow, so it is possible to suppress the discharged air from the air exhaust port 54 from flowing into the air intake port 52. Such a structure of the cooling device 42 functions as a circulation suppression unit, which is formed so that the air flow discharged from the air exhaust port 54 is difficult to return to the air intake port 52. In addition, such a structure of the cooling device 42 also functions as a wind direction control unit, which suppresses the formation of an air flow that flows in a straight line from the air exhaust port 54 to the air intake port 52. A wind direction control unit 62 formed by a wall portion may be further arranged in such a longitudinal configuration.

[0103] Next, through Figure 2 , Figures 15 to 20The water mist supply operation of the water supply equipment system 1 according to the first embodiment of the present invention described above will be described. Figures 15 to 20 In the embodiment, the water mist supply device 4 and the water mist generating unit 22 are installed on the upper part of the bathtub body 12 in a manner that is substantially integrated with the bathtub body 12 of the water supply equipment system 1. Figures 15 to 20 The basic structure of the water supply equipment system 1 shown is Figure 1 and Figure 2 The basic structure of the water supply equipment system 1 shown in FIG. Figures 15 to 20 Also marked with Figure 1 and Figure 2 The same symbols as in the above are used for explanation.

[0104] like Figure 2 As shown, in the standby state before the operation of the water supply equipment system 1 starts, water of about 38°C is stored in the lower half of the retention space 20 of the bathtub body 12. The air temperature of the indoor space 5 in the bathroom 3 is substantially equal to the air temperature in the retention space 20. The water supply passage opening and closing valve 27 and the drainage passage opening and closing valve 31 are closed. The interior of the water storage part 26 is in a waterless state. The ultrasonic vibrator 32 is in a stopped state.

[0105] The user operates the operation unit 28 to start the water mist supply control of the water mist supply device 4. Before the supply of water mist starts, the indoor temperature measuring device 36 measures the air temperature of the indoor space 5, and the control unit 40 recognizes the air temperature of the indoor space 5. The control unit 40 opens the water supply path opening and closing valve 27 while adjusting the supply device 14, and supplies water of appropriate temperature from the water supply path 29 to the water storage part 26. The drainage path opening and closing valve 31 is maintained in a closed state. When a predetermined amount of water is stored in the water storage part 26, the water supply path opening and closing valve 27 is closed.

[0106] The control unit 40 adjusts the temperature of the water in the water storage unit 26 so that the temperature difference between the temperature of the water mist supplied from the water mist supply unit 24 to the staying space 20 and the temperature in the bathroom 3 where the water mist supply device 4 is used before the start of the supply of the water mist becomes 0° C. or more. Next, the control unit 40 operates the ultrasonic vibrator 32 to generate water mist in the water storage unit 26.

[0107] Furthermore, as a modified example, after water is supplied to the water storage section 26, the control section 40 may operate the heater to heat the water from the temperature of the supplied water to 60°C or higher. After the water is heated to 60°C or higher, the control section 40 adjusts the temperature of the water in the water storage section 26 by starting and stopping the heater so that the temperature difference between the temperature of the water mist supplied from the water mist supply section 24 to the staying space 20 and the temperature in the bathroom 3 where the water mist supply device 4 is used before the supply of the water mist starts to be 0°C or higher. Next, the control section 40 operates the oscillator 38, thereby operating the ultrasonic vibrator 32 to generate water mist in the water storage section 26.

[0108] Returning to this embodiment, Fig.15 The middle shows the state immediately after the water mist supply unit 24 starts supplying the water mist into the retention space 20 .

[0109] The water mist generated in the water storage part 26 is supplied from the water mist supply part 24 to the retention space 20 in the bathtub body 12. The water mist naturally overflows from the water mist supply part 24, and as shown by the arrow F1, the water mist is supplied to the retention space 20 while freely falling due to its own weight. In this way, the water mist is suppressed from moving in other directions in addition to the downward movement speed. Therefore, it is difficult for the water mist to move in the retention space 20, such as stirring, diffusion, and rising.

[0110] Fig.16 In the figure, the status is shown after about 10 seconds from the start of water mist supply.

[0111] The water mist continues to be supplied from the water mist supply unit 24 to the retention space 20. The supplied water mist begins to stay above the water surface of the water B and in the lower part of the retention space 20. Since the temperature difference between the temperature of the water mist supplied from the water mist supply unit 24 to the retention space 20 and the temperature of the indoor space 5 where the water mist supply device 4 is used before the start of the water mist supply is 0°C or more, it is difficult to form an upward airflow that exceeds its own weight by the temperature of the water mist. Therefore, the water mist stays in the lower part of the retention space 20.

[0112] Fig.17 In the figure, the state is shown after about 30 seconds from the start of water mist supply.

[0113] The water mist supplying part 24 continues to supply water mist to the staying space 20. The water mist supplied to the staying space 20 gradually increases, and the water mist gradually stays in a higher part in the staying space 20.

[0114] Fig.18 , shows the state after about 1 minute has passed since the start of water mist supply.

[0115] The water mist supplying part 24 continues to supply water mist to the staying space 20. The water mist supplied to the staying space 20 gradually increases, and the water mist stays at a higher part in the staying space 20.

[0116] Fig.19 , shows the state after about 1 minute and 30 seconds from the start of water mist supply.

[0117] The water mist supplying part 24 continues to supply water mist to the staying space 20. The water mist supplied to the staying space 20 further increases, and the water mist stays in the staying space 20 near the top (the upper end 12a of the bathtub body 12).

[0118] Fig. 20 , shows the state after about 2 minutes have passed since the start of water mist supply.

[0119] The mist supply unit 24 continues to supply mist to the retention space 20. The mist supplied to the retention space 20 stays in the portion close to the top (the upper end 12a of the bathtub body 12) in the retention space 20. The mist stays mainly in the retention space 20 in an area above the water surface of the water B and below the top of the retention space 20. A portion of the mist falls on the water B and is absorbed, or becomes water droplets and adheres to the wall surface of the bathtub body 12, or flows out over the upper end 12a of the bathtub body 12. In this way, although a portion of the mist disappears or spreads, the mist mainly stays in the retention space 20. That is, although the mist flows slowly in the retention space 20, it does not spread from the retention space 20, and forms a stable retention layer C. Above the water surface of the water B, the retention layer C is formed by the presence of mist of a certain density or more in a unit space. The retention layer is recognized as a white cloud. The retention layer is formed so that the density of the mist is higher on the lower side and lower on the upper side. Due to the existence of the retention layer, the water mist appears to be filled to the top of the retention space 20 .

[0120] The upper side of the retained water mist is retained at a retention boundary surface 66 (see Figure 2 , Fig. 20 ), formed at a position lower than the height position of the overflow surface 12b of the bathtub body 12 plus the height corresponding to the depth of the bathtub body 12. The retention boundary surface 66 represents the boundary area between the retention layer C and the air layer J, the retention layer C being a layer where the concentration of water mist in the air is above a certain concentration, and the air layer J being a layer where the concentration of water mist in the air is less than a certain concentration. Since the water mist on the retention boundary surface 66 is retained while moving to a certain extent, it is confined to an area with a certain height in the vertical direction and is also confined to an area extending in the horizontal direction. In addition, the overflow surface 12b of the bathtub body 12 is the lowest part on the side wall of the bathtub body 12, that is, the part that first overflows when water is stored to the upper limit of the bathtub body 12.

[0121] In addition, the retention boundary surface 66 on the upper side of the retained water mist is formed at a position higher than the height position of the overflow surface 12b of the bathtub body 12. Moreover, the retention boundary surface 66 on the upper side of the retained water mist is formed at a position lower than the height position obtained by adding a value between 100 mm and 200 mm to the height of the overflow surface 12b of the bathtub body 12. When the retention boundary surface 66 is located at a position higher than the height of the overflow surface 12b of the bathtub body 12, the user can obtain a water mist bathing effect that exceeds that of a bathtub, that is, can obtain a hot water bathing effect to a higher height than that of a bathtub. While the water mist generating unit 22 is driven (used), the water mist is supplied into the bathtub body 12 and the water mist continues to remain.

[0122] The mist generating unit 22 and the mist supplying unit 24 are configured to define the temperature difference between the mist temperature and the room temperature, the mist particle size, the mist supply amount, etc. so that the height position of the staying boundary surface 66 is the predetermined height position as described above.

[0123] Next, through Figure 2 , Figures 15 to 20 Next, the operations of the mist generating unit 22 and the cooling device 42 of the water supply system 1 according to the first embodiment of the present invention described above will be described.

[0124] like Figure 2 As shown, in the standby state before the water supply system 1 starts operating, the ultrasonic vibrator 32 of the mist generating unit 22 is in a stopped state, and the oscillator body 44 of the oscillator 38 of the mist generating unit 22 is in a stopped state.

[0125] When the user operates the operation unit 28 to start the water mist supply control of the water mist supply device 4, the control unit 40 operates the eight oscillators 38 respectively. The eight oscillators 38 transmit high-frequency electricity to the ultrasonic vibrators 32 forming a group through the high-frequency cables 33. Therefore, the eight ultrasonic vibrators 32 operate independently almost simultaneously, and a relatively large amount of water mist is generated in the water storage unit 26.

[0126] Since the oscillator body 44 of the oscillator 38 transmits high frequency electricity for operating the ultrasonic vibrator 32 , heat is generated. The heat generated in the oscillator body 44 is easily transferred to the heat sink 46 a of the heat sink 46 .

[0127] At about the same time as the eight oscillators 38 are operated, the control unit 40 starts driving the blower 48. Fig.10 As shown, by the blower 48, an air flow as indicated by arrow H3 is formed from the air intake port 52 through the cooling flow path 50 to the exhaust port 54. Figure 7) flows between the heat sinks 46a, transferring heat from the heat sinks 46a to the air. Thus, the air flowing along the heat sinks 46a is gradually heated, and the heat sinks 46a of the radiator 46 and the oscillator body 44 are cooled.

[0128] like Figure 4 As shown, the air reaching the air inlet 52 from the outside of the bathroom 3 flows into the air inlet 52 through the opening 62a on the opposite side of the exhaust port 54 as shown by the arrow H1, or flows into the air inlet 52 from a direction different from the exhaust port 54 as shown by the arrow H2. Fig.12 As shown, the air introduced into the air inlet 52 is the external air 11 in the space between the outside 3a of the bathroom 3 and the outer wall 9 of the building. The external air 11 is distinguished from the high-temperature and humid air in the indoor space 5. In addition, the outer wall 9 can be omitted and the air inlet 52 directly introduces the atmosphere outside the building. Then, as shown by arrow H3 (refer to Fig.10 ), by means of the blower 48, air flows from the air intake port 52 through the cooling flow path 50 to the air exhaust port 54.

[0129] Since the air flows between the heat sinks 46a arranged substantially in parallel, the cooling efficiency can be reduced due to the pressure loss of the air flow, and the heat can be dissipated from the heat sink 46a more efficiently. Figure 8 ) and the second region R2, so that the air flows through the flow paths in the radiators 46 arranged in parallel respectively. Compared with the case of flowing through the flow paths in the radiators 46 arranged in one row, the cooling performance of the radiator can be suppressed from being reduced due to the air heated by the radiator on the upstream side flowing through the radiator 46 on the downstream side, and the radiator 46 can be cooled efficiently.

[0130] One oscillator 38 generates heat for transmitting high-frequency electricity to one ultrasonic vibrator 32. The heat generated by one oscillator 38 is suppressed to a lower heat than when power is supplied to a plurality of ultrasonic vibrators 32. The heat generated by such one oscillator 38 can be dissipated by one heat sink 46, and the heat generation of the oscillator 38 can be suppressed, thereby suppressing malfunction of the oscillator 38.

[0131] like Figure 4As shown, the air reaching the exhaust port 54 flows out in a direction away from the intake port 52 after passing through the opening 62a on the opposite side of the intake port 52 as shown by arrow H4, or flows out in a direction different from the intake port 52 (the front direction of the exhaust port 54) as shown by arrow H5. Thus, the wind direction control unit 62 suppresses the formation of an air flow that flows in a straight line from the exhaust port 54 toward the intake port 52, so that the air flow discharged from the exhaust port 54 is difficult to return to the intake port 52. Therefore, it is possible to suppress the air heated by the waste heat of the oscillator 38 from being recirculated from the exhaust port 54 to the intake port 52, thereby preventing the oscillator 38 from being poorly dissipated.

[0132] Next, the effects related to the structure of this embodiment are described. In the first embodiment of the present invention configured as above, the water mist generating unit 22 includes: a plurality of ultrasonic vibrators 32; and a plurality of oscillators 38, and one oscillator 38 is connected to each of the plurality of ultrasonic vibrators 32 in a group. Thus, in the water supply equipment system 1 that can supply both liquid water and mist, even when a plurality of ultrasonic vibrators 32 are provided to increase the amount of mist to be generated, the heat generation of the oscillator 38 can be suppressed and malfunction of the oscillator 38 can be suppressed, and malfunction of the water supply equipment system 1 that can supply both liquid water and mist can be suppressed.

[0133] Furthermore, in the water supply system 1 that can supply both liquid water and mist, the user may think that the supply of liquid water and the supply of mist are related as water supply. Therefore, when the oscillator 38 malfunctions and a problem occurs in the supply of mist, the user may feel uneasy as to whether there is a problem with the supply of liquid water as well.

[0134] Therefore, in one embodiment of the present invention constructed in this way, by suppressing malfunction of the oscillator 38, it is possible to suppress problems in the supply of mist water vapor and give the user a sense of uneasiness as to whether there is a problem in the supply of liquid water, thereby improving the reliability of the water supply equipment system 1 that can supply both liquid water and mist water vapor.

[0135] In addition, in the water supply equipment system 1, even when a plurality of ultrasonic vibrators 32 are provided in order to increase the amount of water mist to be generated, the heat generation of each oscillator 38 can be suppressed, so that the radiator connected to each oscillator 38 can be further miniaturized, the cooling flow path 50 and the cooling device 42 can be further miniaturized, and the water mist supply device 4 formed integrally with the cooling device 42 can be further miniaturized.

[0136] In the first embodiment of the present invention thus constructed, in order to allow the water mist to remain in a retention portion that forms a retention space 20 that is open upward toward the room in which the water supply equipment system 1 is used, even when a plurality of ultrasonic vibrators 32 are provided to increase the generated water mist, the heat generation of each oscillator 38 is suppressed, thereby further suppressing malfunction of the oscillator 38, and further suppressing malfunction of the water supply equipment system 1 that can supply both liquid water and mist-like water mist.

[0137] In one embodiment of the present invention thus configured, the mist generating unit 22 preferably further includes a cooling device 42 for cooling the oscillator 38. This can more effectively dissipate heat from the oscillator 38, suppress heat generation of the oscillator 38, and further suppress malfunction of the oscillator 38.

[0138] In the first embodiment of the present invention thus configured, since the oscillator 38 includes the heat sink 46, it is possible to easily dissipate heat from the oscillator body 44, and since the cooling device 42 includes the air blower 48 that sends air to the heat sink 46, it is possible to further promote heat dissipation from the oscillator body 44. Thus, the oscillator 38 is more effectively dissipated, the heat generation of the oscillator 38 is suppressed, and malfunction of the oscillator 38 can be further suppressed.

[0139] In the first embodiment of the present invention thus configured, the heat sink 46 is arranged to have a portion exposed to the cooling flow path 50, and the cooling flow path 50 allows the air flow generated by the blower 48 to pass through. Thus, the heat sink 46 can be effectively cooled by the air flow, and the heat dissipation of the oscillator body 44 by the heat sink 46 can be further promoted. Thus, the heat dissipation of the oscillator 38 is more effectively performed, the heat generation of the oscillator 38 is suppressed, and the malfunction of the oscillator 38 can be further suppressed.

[0140] In the first embodiment of the present invention thus configured, when viewed from the upstream side of the cooling flow path 50, the plurality of radiators 46 are arranged to be divided into at least a first region R1 in the cooling flow path 50 and a second region R2 that is offset from the first region R1 in the cooling flow path 50. Thus, compared with a case where the plurality of radiators 46 are arranged in series in only one region when viewed from the upstream side of the cooling flow path 50, it is possible to suppress the increase in the temperature of the air reaching the radiator 46 disposed on the downstream side of the cooling flow path 50 among the plurality of radiators 46, and the plurality of radiators 46 can be cooled by an air flow with a small air volume, thereby suppressing the heat generation of the oscillator 38 and further suppressing malfunction of the oscillator 38.

[0141] In the first embodiment of the present invention thus constituted, the water supply equipment system 1 is a bathroom system that can supply both liquid water and mist water into the bathroom 3. Thus, in the bathroom system that can supply both liquid water and mist water into the bathroom 3, even when a plurality of ultrasonic vibrators 32 are provided to increase the amount of water mist to be generated, malfunction of the oscillator 38 can be suppressed by suppressing the heat generation of each oscillator 38, and malfunction of the bathroom system that can supply both liquid water and mist water can be further suppressed.

[0142] In the first embodiment of the present invention thus constituted, even when at least a portion of the cooling flow path 50 of the cooling device 42 is formed in the bathroom 3, the air inlet 52 of the cooling flow path 50 is formed so as to open to the outside of the bathroom 3, and the air outlet 54 of the cooling flow path 50 is also formed so as to open to the outside of the bathroom 3. Thus, it is possible to prevent the high-temperature and humid air in the bathroom 3 from flowing into the cooling flow path 50 from the air inlet 52, and it is possible to prevent the high-temperature and humid air from being supplied to the oscillator 38 in the cooling flow path 50, which may cause the oscillator 38 to short-circuit or the oscillator 38 to be insufficiently radiated, and it is possible to prevent the oscillator 38 from malfunctioning. In addition, since at least a portion of the cooling flow path 50 of the cooling device 42 is formed in the bathroom 3, the cooling flow path 50 of the water supply equipment system 1 can be relatively easily arranged from the bathroom 3, compared with the case where the cooling flow path 50 is completely arranged outside the bathroom 3, and the construction of the water supply equipment system 1 can be further simplified. Therefore, according to one embodiment of the present invention, the water supply system 1 can be constructed more easily from inside the bathroom 3 , and malfunction of the oscillator 38 caused by the high-temperature and humid air in the bathroom 3 can be suppressed.

[0143] In the first embodiment of the present invention thus configured, the cooling device 42 further includes a circulation suppressing unit 56 formed so that the air flow exhausted from the exhaust port 54 is difficult to return to the air intake port 52. Thus, it is possible to suppress the air heated by the waste heat of the oscillator 38 from circulating from the exhaust port 54 to the air intake port 52, thereby suppressing poor heat dissipation of the oscillator 38 and further suppressing malfunction of the oscillator 38.

[0144] In the first embodiment of the present invention thus configured, the circulation suppression unit 56 includes a wind direction control unit 62 that suppresses the formation of an air flow that flows linearly from the exhaust port 54 toward the air intake port 52. This makes it more difficult for the air heated by the waste heat of the oscillator 38 to circulate from the exhaust port 54 to the air intake port 52, and poor heat dissipation of the oscillator 38 can be further suppressed, and poor operation of the oscillator 38 can be further suppressed.

[0145] In the first embodiment of the present invention thus configured, wind direction control unit 62 is formed by a wall portion protruding outward from the outside of bathroom 3 at air inlet 52 or air outlet 54. Thus, air can be prevented from circulating from air outlet 54 to air inlet 52 with a relatively simple structure.

[0146] In the first embodiment of the present invention thus constructed, the wall portion of the wind direction control unit 62 is formed by a tube wall portion, and the tube wall portion is formed by cutting a portion of the tube wall. Thus, by a relatively simple structure, the wall portion can be formed by a tube, and it is possible to make it difficult for air to circulate from the exhaust port to the intake port.

[0147] Next, through Fig.21 A water supply system according to a second embodiment of the present invention will be described. The second embodiment is an example in which the water supply system according to the present invention is applied to a wash area floor of a bathroom. Fig.21 This is a perspective view showing an example in which the water supply equipment system according to the second embodiment of the present invention is applied to a wash area floor.

[0148] Since the basic structure of the water supply equipment system involved in the second embodiment is similar to the water supply equipment system involved in the first embodiment described above, only the parts of the second embodiment of the present invention that are different from the first embodiment are described, and the same reference symbols are marked in the drawings for the same parts or the drawings are omitted and the description is omitted. Regarding the actions and effects of the water supply equipment system involved in the second embodiment of the present invention, since they are the same as the actions and effects of the water supply equipment system involved in the first embodiment, the description is omitted.

[0149] like Fig.21 As shown, a water supply equipment system 101 according to a second embodiment of the present invention is provided in a bathroom 3. The water supply equipment system 101 is a bathroom system that can supply both liquid water and mist water into the bathroom 3. The water supply equipment system 101 comprises: a water supply device 2 that is a water-using device for supplying liquid water; and a mist water supply device 104 that supplies mist water. The water supply equipment system 101 can also be applied to the floor of a washing area in a place other than a bathroom.

[0150] The washing area body 18 forms a retention space 120 on the washing area body side that is open to the indoor space 5 in the bathroom 3. The washing area body 18 is formed by the washing area floor, the wall surface of the bathroom, the outer wall of the bathtub body, the door of the bathroom, etc., and water can flow in the retention space 120 on the inside. The washing area body 18 constitutes a water receiving part that receives water supplied from the washing area side faucet device 8 or the shower faucet device 10. With such a structure, the washing area body 18 allows the water mist to stay in the retention space 120. For example, the washing area body 18 can function as a water receiving part that stores or receives water or water mist inside.

[0151] The mist supply device 104 includes: a mist generating unit 122 for generating mist; and a mist supply unit 24 for supplying the mist generated by the mist generating unit 122 into the washing area body 18. The mist supply device 104 is installed on the wall W on the washing area side. The mist generating unit 122 of the mist supply device 104 of the second embodiment is installed on the wall W on the washing area side. Although this point is different from the mist generating unit 22 of the mist supply device 4 of the first embodiment, the internal structure of the mist supply device 104 of the second embodiment is the same as that of the mist supply device 4 of the first embodiment, so the same parts are referred to the first embodiment and the description is omitted.

[0152] The mist generating unit 122 is disposed above the washing area body 18. The mist supply unit 24 supplies the mist generated by the mist generating unit 122 to the staying portion, i.e., the washing area body 18, which forms a staying space 120 open upward toward the room where the water supply device system 1 is used. The mist supply unit 24 is disposed at a position higher than the floor surface in the washing area body 18.

[0153] The mist generating unit 122 and the mist supply unit 24 control the temperature of the mist while generating the mist so that the mist is easy to stay in the stay space 120. The mist generating unit 122 and the mist supply unit 24 are configured so that the temperature difference between the temperature of the mist supplied from the mist supply unit 24 to the stay space 120 and the temperature of the indoor space 5 used by the water supply equipment system 1 before the start of the mist supply becomes 0°C or more, and the mist supplied from the mist supply unit 24 stays in the stay space 120 of the washing area body 18. Furthermore, even when the temperature of the mist supplied by the mist generating unit 122 and the mist supply unit 24 is the same as the temperature of the indoor space 5 or lower than the temperature of the indoor space 5, it is difficult to form an upward airflow that exceeds the weight of the mist due to the temperature of the mist, and the mist can be kept in the stay space 120.

[0154] The mist generating unit 122 and the mist supplying unit 24 can supply a supply amount per unit volume within a range of, for example, 0.03 mL / min·L to 1.5 mL / min·L. The mist generating unit 122 and the mist supplying unit 24 can supply, for example, 17 mL / min of mist per unit time to the staying space 120 of the washing area body 18 having a volume of 500 L.

[0155] On the floor side of the washing area in the bathroom 3, the cooling device 42 of the mist generating unit 122 is formed by a box-shaped integrated structure that structurally connects the water storage unit 26 and the mist supply unit 24. The air intake port 52 of the cooling flow path 50 of the cooling device 42 is formed in a manner that opens toward the outside of the wall W of the bathroom 3, and the air exhaust port 54 of the cooling flow path 50 is also formed in a manner that opens toward the outside of the wall W of the bathroom 3.

[0156] Next, through Fig. 22 A water supply system according to a third embodiment of the present invention will be described. The third embodiment is an example in which the water supply system according to the present invention is applied to a shower room. Fig. 22 This is a perspective view showing an example in which the water supply equipment system according to the third embodiment of the present invention is applied to a shower room.

[0157] Since the basic structure of the water supply equipment system involved in the third embodiment is similar to the water supply equipment system involved in the first embodiment described above, only the parts of the third embodiment of the present invention that are different from the first embodiment are described, and the same reference symbols are marked in the drawings for the same parts or the drawings are omitted and the description is omitted. Regarding the actions and effects of the water supply equipment system involved in the third embodiment of the present invention, since they are the same as the actions and effects of the water supply equipment system involved in the first embodiment, the description is omitted.

[0158] like Fig. 22 As shown, the water supply equipment system 201 involved in the third embodiment of the present invention is set in a shower room 203 as a bathroom. Therefore, the water supply equipment system 201 is a bathroom system that can supply both liquid water and mist into the bathroom. When viewed from above, the shower room 203 is formed in a shape of a rectangular area with a side of about 0.8m to 2m plus a semicircular area, forming a relatively narrow indoor space. The water supply equipment system 201 includes: a water supply device 202 that is a water supply device for supplying liquid water; and a mist supply device 204 that supplies mist.

[0159] The water supply device 202 includes a shower faucet device 210 that supplies water from a shower head. As long as the water supply device 202 supplies liquid water into the shower room 203, other types of water supply devices may be used.

[0160] The shower faucet device 210 is provided at a wall portion of the shower room 203. The shower faucet device 210 includes a supply device 14 for supplying water, and supplies water from a cold water supply pipe 16 connected to a water supply source such as a water pipe and / or a hot water supply pipe 17 for supplying hot water from a hot water supply machine to the shower room 203 through the supply device 14 receiving a command from the control unit 40. Therefore, the shower faucet device 210 is configured to supply water to the shower room 203 at any time.

[0161] The water supply equipment system 201 further includes a shower stall body 212 that forms a retention space 220 for receiving water mist supplied from a water mist supply unit 24 of the water mist supply device 204 to be described later.

[0162] The shower room body 212 forms a retention space 220 which is open on the top and faces the indoor space 205 where the water supply equipment system 201 is used. The shower room body 212 is formed by the wall surface of the shower room, the door of the shower room, etc., and water can flow in the retention space 220 on the inside. Through such a structure, the shower room body 212 allows the water mist to stay in the retention space 220. Moreover, according to this embodiment, even if the boundary between the indoor space 205 of the shower room 203 and the retention space 220 is not clearly divided by the structure, it means that the retention space 220 can be defined. Considering the water mist supply capacity of the water mist supply device 4, the boundary between the indoor space 205 and the retention space 220 is set at different positions. Considering the water mist supply capacity of the water mist supply device 4, the retention space 220 can be arbitrarily set as a space that can store water mist. Such a retention space 220 is a retention space which is open on the top and faces the indoor space 205. Furthermore, the present invention is not limited to the present embodiment, and even if the boundary between the indoor space 205 and the stay space 220 is not clearly defined by a structure, the stay space 220 can be set based on the same purpose.

[0163] The shower body 212 is a wall surface of the shower room, etc., and water can flow in the retention space 220 inside. The shower body 212 constitutes a water receiving portion that receives water supplied from the shower faucet device 210. The shower body 212 is also a retention portion for retaining water mist. When viewed from above, the shower body 212 is formed in a rectangular shape and one side is formed in an arc shape. The retention space 220 is a space formed inside the shower body 212. When a user uses the shower room, the water mist retains on the lower side of the retention space 220, and the user can take a water mist bath in a seated state or a standing state.

[0164] The water mist supply device 204 is installed on the wall W of the shower room. Although the water mist generating unit 222 of the water mist supply device 204 of the third embodiment is installed on the wall W of the shower room, it is different from the water mist generating unit 22 of the water mist supply device 4 of the first embodiment in this respect, but since the internal structure of the water mist supply device 204 of the third embodiment is the same as that of the water mist supply device 4 of the first embodiment, the first embodiment is referred to for the same parts and the description is omitted.

[0165] The mist generating unit 222 is disposed above the floor of the shower body 212. The mist supplying unit 24 supplies the mist generated by the mist generating unit 222 into the shower body 212, which forms a staying space 220 open to the room where the water supply system 201 is used.

[0166] The mist generating unit 222 and the mist supply unit 24 control the temperature of the mist while generating the mist so that the mist is easy to stay in the stay space 220. The mist generating unit 222 and the mist supply unit 24 are configured so that the temperature difference between the temperature of the mist supplied from the mist supply unit 24 to the stay space 220 and the temperature of the indoor space 205 where the water supply equipment system 201 is used before the start of the mist supply becomes 0°C or more, and the mist supplied from the mist supply unit 24 stays in the stay space 220 of the shower room body 212. Furthermore, even when the temperature of the mist supplied by the mist generating unit 222 and the mist supply unit 24 is the same as the temperature of the indoor space 205 or lower than the temperature of the indoor space 205, it is difficult to form an upward airflow that exceeds the weight of the mist due to the temperature of the mist, and the mist can stay in the stay space 220.

[0167] In the shower room 203, the cooling device 42 of the water mist generating unit 222 is formed by a box-shaped integral structure that is structurally connected to the water storage unit 26 and the water mist supply unit 24. The air intake port 52 of the cooling flow path 50 of the cooling device 42 is formed in a manner that opens toward the outside of the wall W of the shower room 203, and the air exhaust port 54 of the cooling flow path 50 is also formed in a manner that opens toward the outside of the wall W of the shower room 203.

[0168] The water mist generating section 222 and the water mist supplying section 24 are configured so that the temperature difference between the water mist supplied from the water mist supplying section 24 to the staying space 220 and the temperature of the room where the water-using equipment is used before the start of the water mist supplying becomes greater than 0°C, and the water mist supplied from the water mist supplying section 24 stays in the staying space 220 below the shower room body 212. Fig. 22 , a retention layer C of water mist is illustrated as an example in which a retention boundary surface 66 is formed thereon.

[0169] According to such a structure, the heated water mist stays in the staying space 220 of the shower body 212. For example, the shower body 212 is heated by the heated water mist, and the floor of the shower or the staying space 220 can be heated. In addition, the user can also take a water mist bath in the staying space 220 by the heated water mist. In addition, since the heated water mist stays at a relatively high position, the user can take a water mist bath in the staying space 220 even when sitting on the chair 208 inside or standing. In addition, for example, by the heated water mist, the dirt attached to the shower body 212 can be easily cleaned or washed off with high cleaning performance while heating the shower body 212.

[0170] In the structural outer wall of the building 9 (ref. Fig.12 ) is provided inside the room formed by the outer wall 9, and a shower room 203 is provided inside, where air containing high-temperature and high-humidity moisture may be generated. As the relationship between the outer wall 9 and the shower room 203 and the circulation suppression unit 56 in this embodiment are the same as those in the first embodiment, the same parts are referred to in the first embodiment and the description is omitted.

[0171] Next, through Fig.23 A water supply system according to a fourth embodiment of the present invention will be described. The fourth embodiment is an example in which the water supply system according to the present invention is applied to a face washing apparatus. Fig.23 It is a perspective view showing a state where a water supply equipment system according to a fourth embodiment of the present invention is installed in a face washing apparatus.

[0172] Since the basic structure of the water supply equipment system involved in the fourth embodiment is similar to the water supply equipment system involved in the first embodiment described above, only the parts of the fourth embodiment of the present invention that are different from the first embodiment are described, and the same reference symbols are marked in the drawings for the same parts or the drawings are omitted and the description is omitted. Regarding the actions and effects of the water supply equipment system involved in the fourth embodiment of the present invention, since they are the same as the actions and effects of the water supply equipment system involved in the first embodiment, the description is omitted.

[0173] like Fig.23 As shown, a water supply system 301 according to a fourth embodiment of the present invention is installed on a table or the like in a washroom 303. The washroom 303 is a relatively narrow indoor space in which the water supply system 301 is installed. The water supply system 301 includes: a water supply device 302 which is a water supply device for supplying liquid water; and a water mist supply device 304 which supplies mist-like water.

[0174] The water supply device 302 includes a faucet device 308 for supplying water. As long as the faucet device 308 is a water supply device for supplying liquid water into the face washing device body 312, other types of water supply devices may be used.

[0175] The water supply equipment system 301 further includes a washbasin body 312 that forms a retention space 320 for receiving the water mist supplied from the water mist supply unit 24 of the water mist supply device 4, which will be described later.

[0176] The face washing device body 312 forms a retention space 320 which is open at the top toward the indoor space 305 in the face washing room 303. The face washing device body 312 can make water flow in the retention space 320 inside. The face washing device body 312 constitutes a water receiving part which receives water supplied from the faucet device 308. With such a structure, the face washing device body 312 allows the water mist to stay in the retention space 320. For example, the face washing device body 312 can function as a water receiving part which stores or receives water or water mist inside.

[0177] The water mist supply device 304 includes: a water mist generating unit 322 for generating water mist; and a water mist supply unit 24 for supplying the water mist generated by the water mist generating unit 322 to the inside of the washing device body 312. The water mist supply device 304 is installed on the table of the washing table. The water mist generating unit 322 of the water supply equipment system 301 of the fourth embodiment is installed above the table. Although this point is different from the water mist generating unit 22 of the water mist supply device 4 of the first embodiment, the internal structure of the water mist supply device 304 of the fourth embodiment is the same as that of the water mist supply device 4 of the first embodiment, so the first embodiment is referred to for the same parts and the description is omitted.

[0178] The mist generating unit 322 is disposed above the face washing device body 312. The mist supply unit 24 forms an opening at the upper portion of the face washing device body 312. The mist supply unit 24 supplies the mist generated by the mist generating unit 322 into the staying portion, i.e., the face washing device body 312, which forms a staying space 320 opened upward toward the room where the water supply equipment system 301 is used.

[0179] The mist generating unit 322 and the mist supply unit 24 control the temperature of the mist while generating the mist so that the mist easily stays in the staying space 320. The mist generating unit 322 and the mist supply unit 24 are configured so that the temperature difference between the temperature of the mist supplied from the mist supply unit 24 to the staying space 320 and the temperature of the indoor space 305 used by the water supply equipment system 301 before the mist supply starts is 0°C or more, and the mist supplied from the mist supply unit 24 stays in the staying space 320 of the face washing device body 312. Fig.23, a mist retention layer C is illustrated as one on which a retention boundary surface 66 is formed. Furthermore, even when the temperature of the mist supplied by the mist generating unit 322 and the mist supplying unit 24 is the same as or lower than the temperature of the indoor space 305, it is difficult to form an upward airflow exceeding its own weight due to the temperature of the mist, and the mist can be retained in the retention space 320.

[0180] The water mist generating unit 322 and the water mist supplying unit 24 set the supply amount per unit volume to be within the range of 0.03 mL / min·L to 1.5 mL / min·L, for example.

[0181] In the washroom 303, the cooling device 42 of the mist generating unit 322 is formed by a box-shaped integral structure to which the water storage unit 26 and the mist supply unit 24 are structurally connected. The air inlet 52 of the cooling flow path 50 of the cooling device 42 is formed in a manner that opens to the outside of the wall W outside the washroom 303, and the air outlet 54 of the cooling flow path 50 is also formed in a manner that opens to the outside of the wall W outside the washroom 303. In addition, since the washroom 303 is a space that is less likely to become hot and humid than a bathroom, the air inlet 52 and the air outlet 54 may also open in the washroom 303. At this time, in a state where the wall W is omitted, the air inlet 52 and the air outlet 54 may also open to the washroom 303.

[0182] According to the structure of the fourth embodiment thus constituted, the heated water mist stays in the retention space 320 of the face washing device body 312. For example, by allowing the heated water mist to stay in the retention space 320 of the face washing device body 312, the water mist contacts a part of the user's body such as the face, hands, or feet, thereby obtaining moisturizing, improved cleaning performance, a hot bath, a beauty effect, and the like. In addition, the user can also take a water mist bath to wash a part of the body in the retention space 320 by using the heated water mist. In addition, for example, by using the heated water mist, dirt attached to the retention space 320 in the face washing device body 312 can be easily washed or washed off with high cleaning performance while heating the face washing device body 312.

[0183] In the structural outer wall of the building 9 (ref. Fig.12 ) is provided inside the room formed by the face washing device body 312, and a face washing room 303 is provided inside where air containing moisture from the face washing device body 312 may be generated. As for the relationship between the outer wall 9 and the face washing room 303 and the circulation suppression unit 56 in this embodiment, since they are the same as those in the first embodiment, the same parts are referred to the first embodiment and the description is omitted. Furthermore, as a modified example, the wall of the face washing room 303 is formed by the outer wall 9, and the air inlet 52 and the air outlet 54 may also be opened to the outside of the outer wall 9.

[0184] Next, through Fig.24 A water supply system according to a fifth embodiment of the present invention will be described. The fifth embodiment is an example in which the water supply system according to the present invention is applied to a kitchen sink device. Fig.24 This is a perspective view showing a state where a water supply equipment system according to a fifth embodiment of the present invention is installed in a kitchen sink device.

[0185] Since the basic structure of the water supply equipment system involved in the fifth embodiment is similar to the water supply equipment system involved in the first embodiment described above, only the parts of the fifth embodiment of the present invention that are different from the first embodiment are described, and the same reference symbols are marked in the drawings for the same parts or the drawings are omitted and the description is omitted. Regarding the actions and effects of the water supply equipment system involved in the fifth embodiment of the present invention, since they are the same as the actions and effects of the water supply equipment system involved in the first embodiment, the description is omitted.

[0186] like Fig.24 As shown, a water supply system 401 according to a fifth embodiment of the present invention is installed on a table or the like in a kitchen 403. The kitchen 403 is a relatively narrow indoor space in which the water supply system 401 is installed. The water supply system 401 includes: a water supply device 402 which is a water supply device for supplying liquid water; and a water mist supply device 404 which supplies mist-like water.

[0187] The water supply device 402 includes a faucet device 408 for supplying water. As long as the faucet device 408 is a water supply device for supplying liquid water into the kitchen sink body 412, other types of water supply devices may be used.

[0188] The water supply system 401 further includes a kitchen sink body 412 that forms a retention space 420 for receiving water mist supplied from a water mist supply unit 24 of the water mist supply device 404 to be described later.

[0189] The kitchen sink body 412 forms a retention space 420 that is open upward toward the indoor space 405 in the kitchen 403. The kitchen sink body 412 allows water to flow in the retention space 420 inside. The kitchen sink body 412 constitutes a water receiving portion that receives water supplied from the faucet device 408. With such a structure, the kitchen sink body 412 allows water mist to remain in the retention space 420. For example, the kitchen sink body 412 can function as a water receiving portion that stores or receives water or water mist inside.

[0190] The water mist supply device 404 includes: a water mist generating unit 422 for generating water mist; and a water mist supply unit 24 for supplying the water mist generated by the water mist generating unit 322 to the kitchen sink body 412. The water mist supply device 404 is installed above the kitchen sink body 412. Although the water mist generating unit 422 of the water supply equipment system 401 of the fifth embodiment is installed above the kitchen sink body 412, it is different from the water mist generating unit 22 of the water mist supply device 4 of the first embodiment in this respect, the internal structure of the water mist supply device 404 of the fifth embodiment is the same as that of the water mist supply device 4 of the first embodiment, so the same parts are referred to the first embodiment and the description is omitted.

[0191] The mist generating unit 422 is disposed above the kitchen sink body 412. The mist supplying unit 24 forms an opening at the upper portion of the kitchen sink body 412. The mist supplying unit 24 supplies the mist generated by the mist generating unit 422 into the kitchen sink body 412, which is a retention portion and forms a retention space 420.

[0192] The mist generating unit 422 and the mist supply unit 24 control the temperature of the mist while generating the mist so that the mist easily stays in the stay space 420. The mist generating unit 422 and the mist supply unit 24 are configured so that the temperature difference between the temperature of the mist supplied from the mist supply unit 24 to the stay space 420 and the temperature of the indoor space 405 used by the water supply equipment system 401 before the start of the mist supply becomes 0°C or more, and the mist supplied from the mist supply unit 24 stays in the stay space 420 of the kitchen sink body 412. Fig.24 , a mist retention layer C is illustrated as one on which a retention boundary surface 66 is formed. Furthermore, even when the temperature of the mist supplied by the mist generating unit 422 and the mist supplying unit 24 is the same as or lower than the temperature of the indoor space 405, it is difficult to form an upward airflow that exceeds the weight of the mist due to the temperature of the mist, and the mist can be retained in the retention space 420.

[0193] The water mist generating unit 422 and the water mist supplying unit 24 set the supply amount per unit volume to be within the range of, for example, 0.03 mL / min·L to 1.5 mL / min·L.

[0194] In the kitchen 403, the cooling device 42 of the water mist generating unit 422 is formed by a box-shaped integral structure to which the water storage unit 26 and the water mist supply unit 24 are structurally connected. The air intake port 52 of the cooling flow path 50 of the cooling device 42 is formed in a manner that opens to the outside of the wall W outside the kitchen 403, and the air exhaust port 54 of the cooling flow path 50 is also formed in a manner that opens to the outside of the wall W outside the kitchen 403. In addition, since the kitchen 403 is a space that is less likely to become hot and humid than the bathroom, the air intake port 52 and the air exhaust port 54 may also open in the kitchen 403. At this time, in a state where the wall W is omitted, the air intake port 52 and the air exhaust port 54 may also open to the kitchen 403.

[0195] According to the structure of the fifth embodiment thus constituted, the heated water mist stays in the retention space 420 of the kitchen sink body 412. For example, by making the heated water mist stay in the retention space 420 of the kitchen sink body 412, the water mist contacts tableware, equipment to be cleaned, etc., thereby heating the object to be cleaned, and the attached dirt can be cleaned with a higher cleaning performance. In addition, by making the heated water mist contact the object to be cleaned, although the cleaning degree is not reached, the dirt can be easily dropped. In addition, by making the heated water mist stay in the retention space 420 of the kitchen sink body 412, the user in the kitchen sink body 412 can warm his fingers while working. In addition, for example, by heating the kitchen sink body 412, the dirt attached to the retention space 420 in the kitchen sink body 412 can be easily cleaned or washed off with a higher cleaning performance.

[0196] In the structural outer wall of the building 9 (ref. Fig.12 ) is provided inside the room formed by the kitchen sink body 412, and a kitchen 403 is provided inside which air containing moisture from the kitchen sink body 412 may be generated. As the relationship between the outer wall 9 and the kitchen 403 and the circulation suppression unit 56 in this embodiment are the same as those in the first embodiment, the same parts are referred to in the first embodiment and the description is omitted. In addition, as a modified example, the wall of the kitchen 403 is formed by the outer wall 9, and the air inlet 52 and the air outlet 54 may also be opened to the outside of the outer wall 9.
