The mist supply device 4 includes a mist generation section 22 that generates mist, and a mist supply section 24 that supplies the mist generated by the mist generation section 22 into the bathtub body 12. The mist supply device 4 is attached to the wall W.

The mist generating section 22 generates mist from water. The water may be heated and temperature-controlled water, or may be unheated water, such as water supplied from a water supply such as a tap. The mist generation unit 22 may generate temperature-controlled mist by heating mist generated from water. The mist generating section 22 is arranged above the short side portion 12e on the short side of the bathtub body 12.

The mist generation unit 22 includes a water storage unit 26 that stores water therein to generate mist, a water supply channel 29 that supplies water from a water supply source to the water storage unit 26, and a drainage pipe that drains water from the water storage unit 26 to a drain pipe. 30, an ultrasonic transducer 32 provided at the bottom inside the water storage section 26, a water temperature measuring device 34 which is a water temperature detection means provided inside the water storage section 26, and a water temperature measuring device 34 provided at the outside of the water storage section 26. The ultrasonic transducer 32 includes an indoor temperature measuring device 36 as an air temperature detection means, an oscillator 38 that oscillates a predetermined electricity to the ultrasonic transducer 32, and a control section 40 that controls the ultrasonic transducer 32.

The water storage portion 26 is formed into a rectangular parallelepiped shape. A water supply channel 29 and a drainage channel 30 are connected to a lower side wall of the water storage section 26 . A mist supply section 24 is connected to a side wall near the center of the water storage section 26 . The water supply channel 29 is provided with a water supply channel opening/closing valve 27 that opens and closes the water supply channel 29 . The drain channel 30 is provided with a drain channel opening/closing valve 31 that opens and closes the drain channel 30.

The ultrasonic vibrator 32 irradiates (oscillates) the water in the water storage section 26 with ultrasonic waves, vibrates the water on the liquid surface in the water storage section 26, turns the water from the liquid surface into fine particles, and forms predetermined particles. It is possible to generate mist (fog) of diameter. The ultrasonic vibrator 32 is electrically connected to an oscillator 38, and by adjusting the ultrasonic oscillation output, frequency, etc. of the ultrasonic vibrator 32, the particle size of the generated mist can be changed. . The main particle size (for example, the particle size of half or more) of the mist supplied from the mist supply unit 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 even more preferably 4.1 μm or more. The mist generating section 22, the mist supplying section 24, etc. are configured so that the thickness is 10 μm or less.

A plurality of ultrasonic transducers 32 are provided within the water storage section 26 .

The control section 40 is electrically connected to the water temperature measuring device 34, and the control section 40 can recognize the temperature of the water in the water storage section 26 measured by the water temperature measuring device 34.

The indoor temperature measuring device 36 detects the temperature of the air in the indoor space 5 where the bathtub body 12 is placed. The control unit 40 is electrically connected to the indoor temperature measuring device 36, and the control unit 40 can recognize the temperature of the air in the indoor space 5 measured by the indoor temperature measuring device 36. Note that before the mist supply starts (before the mist generation unit 22 is driven), the temperature of the air in the indoor space 5 and the temperature of the air in the retention space 20 are approximately equal or relatively close to each other. Therefore, the control unit 40 can estimate the temperature of the air in the indoor space 5 measured by the indoor temperature measuring device 36 as the temperature of the air in the retention space 20 .

The mist supply section 24 supplies the mist generated by the mist generation section 22 into the bathtub body 12, which is a retention section that forms a retention space 20 that is open at the top toward the room where the water supply equipment system 1 is used. supply The mist supply section 24 forms a flow path extending from the mist generation section 22 to the upper part of one end of the retention space 20, as shown by the cross section of the flow path shown in FIG. The opening of the mist supply section 24 is formed into a horizontally long rectangle along the short side portion 12e of the bathtub body 12 when viewed from the front (from the retention space 20 side). The mist supply section 24 is arranged above the water overflow section 12c in the bathtub body 12. In this embodiment, the overflow portion 12c is the overflow surface 12b of the bathtub body 12. As a modification, the overflow portion 12c may be an overflow port provided within the bathtub body 12. Further, the mist supply section 24 is arranged above the short side portion 12e on the short side of the bathtub body 12.

The mist supply section 24 includes a mist supply channel 24a that extends horizontally from the mist generation section 22 to the upper part of one end of the retention space 20, and a mist supply port section 24b that is connected to the downstream end of the mist supply channel 24a and opens downward. Equipped with. The mist supply channel 24a and the mist supply port 24b form a duct-like channel. The mist supply port 24b is located above the retention space 20 inside the bathtub body 12 from the short side portion 12e.

The mist generation unit 22 and the mist supply unit 24 generate mist, control the temperature of the mist, and facilitate the retention of this mist in the retention space 20. The mist generation unit 22 and the mist supply unit 24 are operated at a temperature between the temperature of the mist supplied from the mist supply unit 24 to the retention space 20 and the temperature of the indoor space 5 in which the water supply equipment system 1 is used before the start of mist supply. The difference is set to 0° C. or more, and the mist supplied from the mist supply unit 24 is configured to be retained in the retention space 20 of the bathtub body 12. In addition, the mist generating section 22 and the mist supplying section 24 of the mist supplying device 4 are supplied with a force that causes the rising airflow generated by the temperature difference between the mist temperature and the temperature of the indoor space 5 to cause the mist to rise. The structure is configured to generate a temperature difference that does not exceed the weight of the mist depending on the particle size of the mist. By setting the temperature of water in the mist generating section 22 or the frequency of the ultrasonic vibrator 32 in advance according to the assumed temperature range of the air in the indoor space 5, it is possible to measure the temperature of the room without using the indoor temperature measuring device 36. Such mist supply may be achieved regardless of the measurement result of the device 36). Moreover, such mist supply may be achieved by adjusting the settings at the time of mist supply. The mist generation unit 22 and the mist supply unit 24 are configured such that the temperature difference is preferably 100°C or less, more preferably 60°C or less, and still more preferably 45°C or less. The mist generation section 22 and the mist supply section 24 control the temperature of the mist and the particle size of the mist, and facilitate the retention of this mist in the retention space 20 . Note that even if the temperature of the mist supplied by the mist generation section 22 and the mist supply section 24 is the same as the temperature of the indoor space 5 or lower than the temperature of the indoor space 5, the rising air flow is strong enough to overcome its own weight. This can be made difficult to occur by changing the temperature of the mist, and the mist can be retained in the retention space 20.

Furthermore, the mist generation unit 22 and the mist supply unit 24 have a supply amount per volume in a range of, for example, 0.03 mL/min·L to 1.5 mL/min·L. The mist generation unit 22 and the mist supply unit 24 can supply mist at a supply rate of 11 mL/min per unit time, for example, to the 330 L retention space of the bathtub body 12. Further, for example, the mist generation section 22 and the mist supply section 24 can supply mist at a supply amount per unit time of 6 mL/min to a retention space with a volume of 4.32 L such as other plumbing equipment. The amount of mist supplied is controlled by the number of ultrasonic transducers 32, the output, the direction in which ultrasonic waves are irradiated, the water level in the mist generating section 22, the shape of the channels in the mist generating section 22 and the mist supplying section 24, etc. can.

Note that the mist generation section 22 may include a heater (not shown) inside the water storage section 26 in order to generate temperature-controlled mist. This heater is electrically connected to the control unit 40, and has a function of heating the water in the water storage unit 26, for example, and a function of controlling the temperature of the water 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 60° C. or higher, which is higher than room temperature. Further, for example, the control unit 40 can control the temperature of water that has been once heated to 60° C. or higher using a heater, so that the temperature is then increased or decreased so that a predetermined temperature difference, which will be described later, is 0° C. or higher. . The mist generating section 22 can be configured without such a heater. For example, the mist generation unit 22 may omit such a heater and generate mist from water that is heated to 60° C. or higher in a water heater and then supplied to the mist generation unit 22. By heating water to 60° C. or higher, the proliferation of at least some bacteria (for example, Legionella) can be suppressed. The mist generating section 22 can generate mist even if the heater is omitted.

The control unit 40 includes a CPU, a memory, etc., and controls connected devices to generate mist based on a predetermined control program recorded in the memory or the like. The control section 40 is electrically connected to an oscillator 38, a water temperature measuring device 34, an indoor temperature measuring device 36, an operating section 28, a blower 48, and the like. The control unit 40 is further electrically connected to a water supply channel opening/closing valve 27 provided in the water supply channel 29 and a drainage channel opening/closing valve 31 provided in the drainage channel, and can control these.

Returning again to this embodiment, the oscillator 38 and cooling device 42 of the mist generating section 22 will be explained in more detail with reference to FIGS. 3 to 14.
A plurality of oscillators 38 are provided within the cooling device 42 . The oscillators 38 are arranged in a row parallel to the wall W along the cooling channel 50 (for example, see FIG. 8). The oscillators 38 are arranged in one row of four in series above the cooling channel 50, and further arranged in one row of four in series below the cooling channel 50, for a total of eight oscillators 38. It is being As shown in FIG. 11, the oscillator bodies 44 of the oscillator 38 are each independently connected to a power source 60 that supplies electricity. The power source 60 is an electricity supply source such as an outlet or a storage battery. Note that the oscillator main body 44 of the oscillator 38 may be electrically connected to the oscillator main body 44 of another oscillator 38.

The oscillator 38 includes an oscillator body 44 and a heat sink 46 connected to the oscillator body 44 to release heat from the oscillator body 44. The oscillator main body 44 is formed as a plate-shaped member. An electric circuit for realizing the function of the oscillator 38 is arranged on the oscillator body 44. The oscillator main body 44 has an electric circuit configuration that can oscillate electricity at a high frequency voltage such as 2.4 MHz. The oscillator main body 44 is electrically connected to the control section 40. Oscillator body 44 may generate heat in the electrical circuit. A portion of the oscillator body 44 is exposed to a cooling device internal space 51 (see FIG. 8) in the cooling device 42 that is different from the cooling channel 50. The cooling device internal space 51 within the cooling device 42 is separated from the indoor space 5 which becomes hot and humid in the bathroom 3. The cooling device internal space 51 is formed so that high temperature and humid air from the indoor space 5 does not easily flow into the cooling device internal space 51, thereby suppressing failure of the oscillator main body 44, which is an electrical component. The oscillator main body 44 is connected to a heat sink 46 using a metal with relatively low thermal resistance, a ceramic member with relatively high thermal conductivity, or the like. In the oscillator main body 44, a metal or the like having relatively low thermal resistance extends particularly from the connecting portion of the heat sink 46 to the substrate on which the electric circuit is arranged. Note that in the oscillator main body 44, the heat sink 46 and a substrate on which an electric circuit is arranged may be directly connected.

As shown in FIG. 11, the oscillator 38 is a combination of each of the plurality of ultrasonic transducers 32 and one oscillator 38 (a single ultrasonic transducer 32 and a single oscillator 38). oscillator 38). One set of one ultrasonic transducer 32 and one oscillator 38 is formed to use a high frequency output of 50 W or less, for example. The set of combinations of the oscillator main body 44 and the ultrasonic transducers 32 can be configured freely; for example, one oscillator main body 44 and a plurality of ultrasonic transducers 32 form one set; Each may be independently connected to the power source 60.

The oscillator 38 and the ultrasonic transducer 32 are connected by a high frequency cable 33 that can transmit electricity at a high frequency such as 2.4 MHz. The high frequency cable 33 has a length that maintains sufficient electricity transmission performance to transmit electricity at a high frequency such as 2.4 MHz. In general, the shorter the high-frequency cable 33 is formed, the more efficiently electricity can be transmitted. Therefore, the length from each ultrasonic transducer 32 to each oscillator 38 via the high-frequency cable 33 is restricted to a relatively short length, and since the ultrasonic transducer 32 is placed inside the bathroom 3, the oscillator 38 It is also preferable that the bathroom 3 be placed in the bathroom 3 in order to improve maintainability, workability, etc. Furthermore, the cooling device 42 of the mist generating section 22 is formed of an integral structure (in this embodiment, an integral box shape) that is structurally connected to the water storage section 26, the mist supply section 24, etc. in the bathroom 3. There is.

The heat sink 46 is arranged within the cooling channel 50 so as to have a portion exposed to the cooling channel 50. The heat sink 46 includes a plurality of heat sinks 46a made of metal such as aluminum. A heat sink 46 a of the heat sink 46 is arranged so as to be exposed to the cooling channel 50 . The heat radiation plate 46a of the heat sink 46 extends parallel to the flow direction G of the cooling channel 50 (see FIGS. 7 and 10), and a plurality of heat radiation plates 46a are arranged vertically and substantially parallel to each other. A base 46b (see FIGS. 8 and 5) of a heat sink 46a of the heat sink 46 is connected to the oscillator body 44.

The plurality of heat sinks 46 are arranged in a first region R1 in the cooling channel 50 (see FIG. 8 ) and a second region R2 shifted from the first region R1 in the cooling flow path 50. The first region R1 and the second region R2 are mainly located in different regions, but may partially overlap. For example, the first region R1 is a part of the upper region on the upper side of the cooling passage 50, and the second region R2 is a part of the lower part of the lower part of the cooling passage 50. Four heat sinks 46 are arranged in series within the first region R1 of the cooling channel 50 along the inner wall 50a (see FIGS. 8 and 10). Moreover, four heat sinks 46 are arranged in series along the inner wall 50a of the cooling channel 50 within the second region R2 of the cooling channel 50. Further, as shown in FIG. 8, when looking from the upstream side (or intermediate portion) to the downstream side of the cooling channel 50, there are one heat sink 46 in each of the first region R1 and the second region R2. They are arranged vertically in parallel. Note that the heat sinks 46 (oscillators 38) do not necessarily have to be arranged vertically in parallel; for example, the heat sinks 46 in the upper stage are closer to the wall, the heat sinks 46 in the lower stage are closer to the indoor side, etc. They may be shifted from each other. Further, the upper and lower stages may be shifted from each other such that the upper heat sink 46 is closer to the upstream side of the cooling channel 50 and the lower heat sink 46 is closer to the downstream side of the cooling channel 50. Further, the heat sinks 46 (oscillators 38) do not need to be arranged in two rows, an upper row and a lower row, but may be arranged in three rows, an upper row, a middle row, and a lower row. Further, the heat sinks 46 do not need to be arranged evenly, and can be freely arranged such as four on the upper stage, three on the lower stage, and one in the middle region on the downstream side thereof.

The mist generating section 22 further includes a cooling device 42 that cools the oscillator 38. The cooling device 42 includes a blower 48 that generates a flow of air to a heat sink 46 , a cooling channel 50 that extends from an intake port 52 to an exhaust port 54 and passes the air flow generated by the blower 48 , and a cooling channel 50 that generates an air flow from the exhaust port 54 to an exhaust port 54 . A circulation suppressing means 56 is formed so that the flow of air is difficult to return to the intake port 52.

The blower 48 is configured to send air flowing in from the intake port 52 toward the exhaust port 54 . The blower 48 generates an air flow in a direction parallel to the direction in which the cooling channel 50 extends. The blower 48 includes blades (not shown) that send out air and an electric drive unit (not shown) that rotates the blades. The blower 48 is formed, for example, by a fan that generates wind. The blower 48 is driven in response to a command from the control unit 40. The blower 48 forcibly sends air toward the heat sink 46, further improving the cooling capacity compared to natural air cooling. Although the cooling device 42 in this embodiment employs a forced air cooling method using a blower 48, it may also employ a natural air cooling method omitting the blower 48, or may use water to remove heat from the heat sink 46. A water cooling method may also be adopted in which the water is removed. Further, although the blower 48 is arranged on the upstream side of the cooling channel 50, it may be arranged on the downstream side. Further, although the blower 48 is provided so as to cause a flow of air toward the heat sink 46 in the cooling channel 50, it may be provided so as to cause a flow of air toward the oscillator body 44.

At least a portion of the cooling channel 50 of the cooling device 42 is formed within the bathroom 3. The cooling flow path 50 forms an air flow path within the bathroom 3 that is separated from the indoor space 5 . The cooling channel 50 forms a duct-like channel from the intake port 52 to the exhaust port 54 . The cooling channel 50 is formed so that high temperature and humid air generated from a bathtub or the like in the indoor space 5 is difficult to flow into the cooling channel 50, thereby suppressing a decrease in cooling efficiency in the cooling channel 50. The cooling flow path 50 forms a space in which two heat sinks 46 can be arranged vertically in parallel. As shown in FIG. 8, for example, the cooling channel 50 forms a rectangular channel cross section, and one vertical side of the cooling channel 50 has a height of about two heat sinks 46. One horizontal side in the left-right direction is formed to have a width approximately equal to one heat sink 46. Therefore, in the region in the cooling channel 50 where the heat sink 46 is arranged, the heat sink 46 is arranged so as to occupy the majority of the region in the cooling channel 50, and the cooling efficiency of the heat sink 46 is improved. Since the cooling channel 50 is also partitioned from the cooling device internal space 51, the flow of air flowing within the cooling channel 50 is disturbed by irregularities such as elements of the electric circuit of the oscillator main body 44, and pressure loss in the flow occurs. Therefore, it is possible to suppress a decrease in cooling efficiency. That is, the heat sink 46 is mainly disposed within the cooling flow path 50, and by preventing unevenness such as the elements of the electric circuit of the oscillator body 44 from forming inside, the cooling efficiency is improved due to the pressure loss of the flow. The cooling efficiency is improved. Note that the oscillator body 44 may be provided such that the elements of the electric circuit of the oscillator body 44 are disposed within the cooling channel 50.

The intake port 52 of the cooling channel 50 is formed to open toward the outside of the bathroom 3, and the exhaust port 54 of the cooling channel 50 is also formed to open toward the outside of the bathroom 3. The intake port 52 forms a circular opening and extends from the outside to the inside of the bathroom 3. The exhaust port 54 forms a circular opening and extends from the inside to the outside of the bathroom 3.

As shown in FIG. 4 and the like, the circulation suppressing means 56 includes a wind direction control section 62 that suppresses the formation of a flow of air flowing linearly from the exhaust port 54 toward the intake port 52. The wind direction control unit 62 is formed by a wall portion that projects outward from the outer surface 3 a of the bathroom 3 at the intake port 52 or the exhaust port 54 .
The wind direction control unit 62 is formed as a pipe wall section formed by cutting out a part of the pipe wall of a pipe that protrudes outward from the outer surface 3a of the bathroom 3 at the intake port 52 and/or the exhaust port 54. . Pipes include pipes other than circular pipes. The wind direction control section 62 is formed by an arcuate wall section at the intake port 52 and/or the exhaust port 54 . In this way, the wind direction control section 62 may be disposed only at either the intake port 52 or the exhaust port 54.

The airflow direction control unit 62 is formed in a C-shape in which an arc portion corresponding to an angle range of 90 degrees is cut out from the entire circumference of the circular pipe when viewed from the front of the intake port 52, etc., and is an opening that opens in a direction along the outer surface 3a. A portion 62a is formed. The opening 62a of the wind direction control section 62 opens toward the side opposite to the exhaust port 54 at the intake port 52. Further, the opening 62a of the wind direction control section 62 opens toward the opposite side of the air intake port 52 at the exhaust port 54. The wind direction control unit 62 is provided so as to suppress the formation of a linear flow of air from the exhaust port 54 toward the intake port 52 . Further, the wind direction control unit 62 can suppress the flow of air flowing out from the exhaust port 54 toward the intake port 52 at the exhaust port 54 , and prevent the flow of air from flowing out from the exhaust port 54 toward the intake port 52 at the intake port 52 . It is possible to suppress the flow of incoming air from occurring. The wind direction control section 62 may be a flat wall. Further, the wind direction control section 62 may be formed by a partition-like wall or a protrusion provided at the position of the exhaust port 54 and/or the intake port 52. Further, the opening 62a does not necessarily have to open toward the opposite side from the intake port 52 and the exhaust port 54, but may be opened in a direction that makes it difficult to form a flow from the exhaust port 54 toward the intake port 52. Bye. Further, the circulation suppressing means 56 is provided at a position on a straight line connecting the intake port 52 and the exhaust port 54 so as to suppress the formation of a flow of air flowing linearly from the exhaust port 54 toward the intake port 52. It may also be formed by a partition-like wall or a protrusion. The wind direction control unit 62 also controls the opening direction of the exhaust port 54 and/or the intake port 52 so as to suppress the formation of a flow of air flowing linearly from the exhaust port 54 toward the intake port 52. It may be formed in a direction different from the direction from 54 to the intake port 52. For example, the wind direction control unit 62 may be formed by an L-shaped pipe extending outward from the outer surface of the bathroom 3, and the exhaust port 54 may open toward the opposite side from the intake port 52, and the air intake port 52 may open toward the opposite side from the intake port 52. It may be opened toward the side opposite to 54. That is, the wind direction control section 62 does not need to be formed by cutting out a part of the tube wall of the tube. Further, the exhaust port 54 and/or the intake port 52 are arranged with respect to the wall W so that the opening direction of the exhaust port 54 and/or the intake port 52 is different from the direction from the exhaust port 54 toward the intake port 52. It may also be formed obliquely. The wind direction control section 62 does not need to have a wall projecting outward from the outer surface 3a as long as the opening directions are different.
In addition, as a modification, the wind direction control unit 62 may be formed so that the air flowing out from the exhaust port 54 toward the intake port 52 becomes difficult to flow toward the intake port 52. For example, the wind direction is set so that air flowing out from the exhaust port 54 in a diagonal direction with respect to a straight line connecting the exhaust port 54 and the intake port 52 is suppressed from flowing toward the intake port 52 by bypassing the straight line. A control section 62 may also be formed.

When a bathroom 3 is provided in a building, hot and humid air is generated inside the room formed by the structural outer wall 9 of the building (including the internal structural wall of the building). It is well known that a possible bathroom 3 is provided. In such a case, in order to secure space for other rooms or to efficiently arrange the bathroom 3, the gap D between the structural outer wall 9 of the building and the bathroom 3 (Fig. 12 ) is often a relatively narrow gap of several centimeters. If the gap D between the outer wall 9 and the bathroom 3 is relatively small in this way, the space for air to flow is limited, creating an environment in which air tends to flow from the exhaust port 54 toward the intake port 52. Suppressing the formation of a linear flow of air from the exhaust port 54 toward the intake port 52 by the control unit 62 is particularly effective for suppressing recirculation of warm air.

As shown in FIG. 13, as a modified example, the wind direction control unit 62 is formed in a C-shape in which an arc portion corresponding to an angular range of 180 degrees is cut out from the entire circumference of the circular pipe when viewed from the front of the intake port 52, etc. An opening 62a may be formed which opens in the direction along the outer surface 3a.
As shown in FIG. 14, as a further modified example, the wind direction control unit 62 has a C-shape in which an arc portion corresponding to an angular range of 270 degrees is cut out from the entire circumference of the circular pipe when viewed from the front of the intake port 52, etc. An opening 62a that opens in the direction along the outer surface 3a may be formed. In this way, the wind direction control section 62 can be formed by a circular arc portion having an arbitrary angle range, and the size, length, etc. can be changed.

In addition, as a further modification, the cooling channel 50 of the cooling device 42 is formed to extend in the vertical direction so that the intake port 52 and the exhaust port 54 of the cooling channel 50 of the cooling device 42 are arranged in the vertical direction. You can leave it there. At this time, for example, the intake port 52 is arranged at the bottom, and the exhaust port 54 is arranged above the intake port 52. If arranged in this way, the warmed air discharged from the intake port 52 will easily form an upward air current, so that the discharged air can be suppressed from flowing from the exhaust port 54 to the intake port 52. The configuration of the cooling device 42 functions as a circulation suppressing means formed so that the flow of air exhausted from the exhaust port 54 is difficult to return to the intake port 52. The configuration also functions as a wind direction control unit that suppresses the formation of a straight air flow from the exhaust port 54 toward the intake port 52. In addition to this vertical arrangement, a wind direction control section 62 formed by a wall section may be arranged.

Next, the mist supplying operation of the water supply equipment system 1 according to the first embodiment of the present invention described above will be described with reference to FIGS. 2, 15 to 20.
In FIGS. 15 to 20, the mist supply device 4 and the mist generation section 22 are incorporated in the upper part of the bathtub body 12 of the water supply equipment system 1 so as to appear almost integral with the bathtub body 12. The basic structure of the water supply equipment system 1 shown in FIGS. 15 to 20 is almost the same as the basic structure of the water supply equipment system 1 shown in FIGS. The description will be given using the same reference numerals as in FIG. 2 and the like.

As shown in FIG. 2, in a standby state before the water supply system 1 starts operating, water at about 38° C. is stored in the lower half of the retention space 20 of the bathtub body 12. The temperature of the air in the indoor space 5 in the bathroom 3 and the temperature of the air in the retention space 20 are approximately the same. The water supply channel opening/closing valve 27 and the drainage channel opening/closing valve 31 are closed. There is no water in the water storage section 26. The ultrasonic transducer 32 is in a stopped state.

The user operates the operation unit 28 to start mist supply control of the mist supply device 4. Before starting the supply of mist, the indoor temperature measuring device 36 measures the temperature of the air in the indoor space 5, and the control unit 40 recognizes the temperature of the air in the indoor space 5. The control unit 40 adjusts the supply device 14 and opens the water supply channel opening/closing valve 27 to supply water at an appropriate temperature from the water supply channel 29 into the water storage section 26 . The drain opening/closing valve 31 remains closed. When a predetermined amount of water is stored in the water storage section 26, the water supply channel opening/closing valve 27 is closed.

The control unit 40 determines that the temperature difference between the temperature of the mist supplied from the mist supply unit 24 to the retention space 20 and the temperature in the bathroom 3 where the mist supply device 4 is used before the start of mist supply is 0°C or more. The temperature of the water in the water storage section 26 is adjusted so that the temperature of the water is increased. Next, the control section 40 operates the ultrasonic vibrator 32 to generate mist within the water storage section 26 .
As a modification, after supplying water into the water storage section 26, the control section 40 may operate a heater to heat the water from the temperature of the supplied water to 60° C. or higher. The control unit 40 controls the temperature of the mist supplied from the mist supply unit 24 to the retention space 20 after the water is heated to 60° C. or higher, and the temperature of the mist in the bathroom 3 where the mist supply device 4 is used before starting the mist supply. The temperature of the water in the water storage section 26 is adjusted by starting and stopping the heater so that the temperature difference between the water storage section and the water storage section 26 is 0.degree. C. or more. Next, the control unit 40 operates the ultrasonic vibrator 32 by operating the oscillator 38 to generate mist within the water storage unit 26 .

Returning to the present embodiment again, FIG. 15 shows a state immediately after the mist supply unit 24 starts supplying the mist into the retention space 20.
The mist generated within the water storage section 26 is supplied from the mist supply section 24 to the retention space 20 within the bathtub body 12. The mist naturally overflows from the mist supply section 24 and is supplied into the retention space 20 while falling freely due to its own weight, as shown by arrow F1. In this way, the mist is suppressed from having a moving speed in any direction other than the downward moving speed. Therefore, it is difficult for the mist to move, such as stirring, spreading, and rising, within the retention space 20.

FIG. 16 shows the state approximately 10 seconds after the start of mist supply.
The supply of mist from the mist supply unit 24 to the retention space 20 is continued. The supplied mist has started staying above the water surface of water B and in a low part within the retention space 20. The temperature difference between the temperature of the mist supplied from the mist supply unit 24 to the retention space 20 and the temperature of the indoor space 5 in which the mist supply device 4 is used before starting the mist supply is 0°C or more. Because of this, the temperature of the mist makes it difficult for the mist to generate an upward current that is strong enough to overcome its own weight. Therefore, the mist stays in a relatively low portion within the retention space 20.

FIG. 17 shows the state approximately 30 seconds after the start of mist supply.
The supply of mist from the mist supply unit 24 to the retention space 20 is continued. The mist supplied into the retention space 20 gradually increases, and the mist is gradually retained up to a higher part of the retention space 20.

In FIG. 18, the state is shown approximately one minute after the start of mist supply.
The supply of mist from the mist supply unit 24 to the retention space 20 is continued. The mist supplied into the retention space 20 gradually increases, and the mist is being retained up to a higher part of the retention space 20.

FIG. 19 shows the state after approximately 1 minute and 30 seconds have elapsed since the start of mist supply.
The supply of mist from the mist supply unit 24 to the retention space 20 is continued. The mist supplied into the retention space 20 further increases, and the mist is retained up to a portion of the retention space 20 close to the top (the upper end 12a of the bathtub body 12).

In FIG. 20, the state is shown approximately 2 minutes after the start of mist supply.
The supply of mist from the mist supply unit 24 to the retention space 20 is continued. The mist supplied into the retention space 20 is retained up to a portion of the retention space 20 close to the top (the upper end 12a of the bathtub body 12). The mist mainly stays in a region above the water surface of the water B and below the top of the staying space 20 . Some of the mist falls into the water B and is absorbed, or is attached to the wall surface of the bathtub body 12 as water droplets, or flows out beyond the edge of the upper end 12a of the bathtub body 12. Although some of the mist disappears or diffuses in this way, the main mist remains in the retention space 20. That is, although the mist flows slowly within the retention space 20, it does not diffuse from the retention space 20 and forms a stable retention layer C. The retention layer C is formed above the water surface of the water B by the presence of mist having a density of a certain level or higher in a unit space. The stagnant layer is recognized as a white cloud. The retention layer is formed such that the density of the mist is relatively high on the lower side and the density of the mist is relatively low on the upper side. Due to the presence of the retention layer, it appears that the retention space 20 is filled to the top with mist.

The retention boundary surface 66 (see FIGS. 2 and 20) on the upper side of the retained mist has a height equal to the height of the overflowing surface 12b of the bathtub body 12 plus a height corresponding to the depth of the bathtub body 12. It is formed below the position. The retention boundary surface 66 indicates the boundary area between the retention layer C where the concentration of mist in the air is above a certain level and the air layer J where the concentration of mist in the air is less than a certain level. Since the mist moves to some extent while staying, the retention boundary surface 66 is defined as a region that is slightly taller in the vertical direction, and is also defined as a region that spreads in the horizontal direction. The overflow surface 12b of the bathtub body 12 is the lowest part of the side wall of the bathtub body 12, that is, the part that first overflows when water accumulates up to the upper limit of the bathtub body 12.

Further, the retention boundary surface 66 on the upper side of the retained mist is formed above the height position of the overflowing surface 12b of the bathtub body 12. Furthermore, the retention boundary surface 66 on the upper side of the retained mist is formed below the height position of the overflow surface 12b of the bathtub body 12 plus a value between 100 mm and 200 mm. When the retention boundary surface 66 is at a position higher than the height of the overflowing surface 12b of the bathtub body 12, the user cannot obtain the mist bathing effect up to a position beyond the bathtub, that is, the hot bathing effect up to a height higher than the bathtub. can. While the mist generating section 22 is being driven (used), mist is supplied into the bathtub body 12 and the mist continues to stay there.
The mist generation unit 22 and the mist supply unit 24 are configured to maintain the temperature difference between the temperature of the mist and the indoor temperature so that the height position of the retention boundary surface 66 is at the predetermined height position as described above, and the mist particles. It is configured to specify the diameter, mist supply amount, etc.

Next, the operations of the mist generating section 22 and the cooling device 42 of the water supply equipment system 1 according to the first embodiment of the present invention described above will be explained with reference to FIGS. 2, 15 to 20.

As shown in FIG. 2, in a standby state before the start of operation of the water supply equipment system 1, the ultrasonic vibrator 32 of the mist generating section 22 is in a stopped state, and the oscillator main body 44 of the oscillator 38 of the mist generating section 22 is in a stopped state. It becomes.

When the user operates the operation unit 28 to start controlling the mist supply of the mist supply device 4, the control unit 40 operates the eight oscillators 38 individually. Each of the eight oscillators 38 transmits high-frequency electricity to a set of ultrasonic transducers 32 via a high-frequency cable 33. Therefore, the eight ultrasonic transducers 32 are operated independently and almost simultaneously, and a relatively large amount of mist is generated within the water storage section 26.

Each of the oscillator bodies 44 of the oscillator 38 generates heat because it transmits high-frequency electricity to operate the ultrasonic transducer 32. Heat generated in the oscillator main body 44 is easily transmitted to the heat sink 46a of the heat sink 46.

The control unit 40 starts driving the blower 48 almost simultaneously with operating the eight oscillators 38 . Therefore, as shown in FIG. 10, an air flow as shown by arrow H3 is formed by the blower 48 from the intake port 52 to the exhaust port 54 via the cooling channel 50. The air flow along the flow direction G (see FIG. 7) flows between the heat sinks 46a, transferring heat from the heat sinks 46a to the air. Therefore, the flow of air flowing along the heat sink 46a is gradually warmed, and the heat sink 46a of the heat sink 46 and the oscillator main body 44 are cooled.

As shown in FIG. 4, air from the outside of the bathroom 3 to the intake port 52 flows toward the intake port 52 through an opening 62a on the opposite side to the exhaust port 54, as shown by arrow H1, or , as shown by arrow H2, flows toward the intake port 52 from a direction different from that of the exhaust port 54. As shown in FIG. 12, the air introduced into the intake port 52 is outside air 11 in the space between the outer surface 3a of the bathroom 3 and the outer wall 9 of the building. This outside air 11 is distinguished from the hot and humid air within the indoor space 5. Note that the outer wall 9 may be omitted and the air intake port 52 may be provided to directly introduce the atmosphere from outside the building. Thereafter, the air flows from the intake port 52 to the exhaust port 54 via the cooling channel 50 by the blower 48, as shown by arrow H3 (see FIG. 10).

Since the air flows between the heat sinks 46a arranged substantially in parallel, it is possible to suppress a decrease in cooling efficiency due to the pressure loss of the flow, and it is possible to remove heat from the heat sinks 46a relatively efficiently. Further, since the plurality of heat sinks 46 are arranged at least separately into the first region R1 (see FIG. 8) and the second region R2, air passes through the flow paths in the heat sinks 46 arranged in parallel. As a result, compared to the case where air passes through the flow paths in the heat sinks 46 arranged in a row, the air already heated in the upstream heat sink passes through the downstream heat sink 46, reducing the cooling performance of the heat sink. Therefore, the heat sink 46 can be efficiently cooled.

One oscillator 38 generates heat for transmitting high-frequency electricity to one ultrasonic transducer 32. The amount of heat generated by one oscillator 38 is suppressed to a lower amount of heat than when electricity is supplied to a plurality of ultrasonic transducers 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.

It's suppressed. Therefore, it is possible to prevent air that has already been warmed by the waste heat of the oscillator 38 from being recirculated from the exhaust port 54 to the intake port 52, thereby preventing heat radiation failure of the oscillator 38 from occurring.

The water supply device system 401 includes a water supply device 402, which is a plumbing device that supplies liquid water, and a mist supply device 404, which supplies mist.

The water supply device 402 includes a faucet device 408 that supplies water. The faucet device 408 may be any other type of water supply device as long as it supplies liquid water into the kitchen sink body 412.

The water supply equipment system 401 further includes a kitchen sink body 412 that forms a retention space 420 that receives mist supplied from a mist supply section 24 of the mist supply device 404, which will be described later.

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 is configured to allow water to flow into a 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 main body 412 allows mist to be retained in the retention space 420. For example, the kitchen sink body 412 can function as a water receptacle for storing or receiving water or mist therein.

The mist supply device 404 includes a mist generation section 422 that generates mist, and a mist supply section 24 that supplies the mist generated by the mist generation section 322 into the kitchen sink main body 412. The mist supply device 404 is attached above the kitchen sink main body 412. The mist generation unit 422 of the water supply equipment system 401 of the fourth embodiment is different from the mist generation unit 22 of the mist supply device 4 of the first embodiment in that it is attached above the kitchen sink main body 412. The internal structure of the mist supply device 404 of the fourth embodiment is the same as that of the mist supply device 4 of the first embodiment, so the description of the similar parts will be omitted by referring to the first embodiment.

The mist generating section 422 is arranged above the kitchen sink main body 412. The mist supply section 24 forms an opening in the upper part of the kitchen sink main body 412.

The mist generation unit 422 and the mist supply unit 24 generate mist, control the temperature of the mist, and facilitate the retention of this mist in the retention space 420. The mist generation unit 422 and the mist supply unit 24 are operated at a temperature between the temperature of the mist supplied from the mist supply unit 24 to the retention space 420 and the temperature of the indoor space 405 in which the water supply equipment system 401 is used before the start of mist supply. The difference is set to 0° C. or more, and the mist supplied from the mist supply section 24 is configured to be retained in the retention space 420 of the kitchen sink main body 412. FIG. 24 illustrates a mist retention layer C that forms a retention boundary surface 66 on the upper surface. Note that even if the temperature of the mist supplied by the mist generation unit 422 and the mist supply unit 24 is the same as the temperature of the indoor space 405 or lower than the temperature of the indoor space 405, the upward airflow is strong enough to overcome its own weight. This can be made difficult to occur by changing the temperature of the mist, and the mist can be retained in the retention space 420.

Further, the mist generation unit 422 and the mist supply unit 24 have a supply amount per volume in a range of, for example, 0.03 mL/min·L to 1.5 mL/min·L.

The cooling device 42 of the mist generating section 422 is formed in the kitchen 403 by a box-shaped integral structure that is structurally connected to the water storage section 26, the mist supply section 24, and the like. The intake port 52 of the cooling channel 50 of the cooling device 42 is formed to open toward the outside of the wall W toward the outside of the kitchen 403, and the exhaust port 54 of the cooling channel 50 also opens toward the outside of the kitchen 403. It is formed to open toward the outside of the wall W. The interior of the kitchen 403 is a space that is less likely to become hot and humid than the bathroom, so the intake port 52 and the exhaust port 54 may be opened within the kitchen 403. At this time, the intake port 52 and the exhaust port 54 may be opened into the kitchen 403 with the wall W omitted.

According to the structure of the fifth embodiment configured in this way, the heated mist is retained in the retention space 420 of the kitchen sink main body 412. For example, by retaining heated mist in the retention space 420 of the kitchen sink body 412 and exposing tableware, equipment to be washed, etc. to the mist, the objects to be washed are warmed and the attached dirt is removed with relatively high cleaning performance. Can be washed with. In addition, by applying the heated mist to the object to be washed, dirt can be removed more easily, even if it is not completely cleaned. Further, the heated mist is retained in the retention space 420 of the kitchen sink body 412, so that the user can work while warming his/her hands and fingers inside the kitchen sink body 412. Further, for example, the heated mist can warm the kitchen sink main body 412 and make it easier to clean or remove dirt adhering to the retention space 420 in the kitchen sink main body 412 with relatively high cleaning performance.

A kitchen 403 is provided inside the room defined by the structural exterior wall 9 of the building (see FIG. 12), in which humid air from the kitchen sink body 412 can occur. The relationship between the outer wall 9 and the kitchen 403, the circulation suppressing means 56, and the like in this embodiment are also the same as in the first embodiment, so the description of the similar parts will be omitted by referring to the first embodiment. In addition, as a modification, the wall of the kitchen 403 may be formed by the outer wall 9, and the intake port 52 and the exhaust port 54 may be opened to the outside of the outer wall 9.
