  The present invention relates to a bathroom air conditioner that controls the air conditioning of a bathroom space.

Conventionally, what is described in following patent document 1 is proposed as an example of such a bathroom air conditioner. Patent Document 1 listed below describes a mist cooling device that ejects cool water mist in order to provide a comfortable bathing environment when bathing in the summer. Specifically, as shown in paragraph No. 23, after using a mist sauna, simply relying on heat dissipation does not cause the temperature in the bathroom to drop quickly, and in particular, in the summer, the bather is uncomfortable. In some cases, the temperature of the bathroom can be lowered early and moderately, and a cool water mist with fine water can be sprayed for the purpose of providing the bather with a comfortable cool-down after the mist sauna. A configuration in which a mist nozzle is provided is disclosed.
JP-A-8-164183

  In the conventional technology described above, for the purpose of quickly reducing the temperature in the bathroom after the mist sauna and providing a comfortable cool-down for the bather, by blowing cool water from the mist nozzle in the bathroom, A technique for lowering the temperature in the bathroom is disclosed. In other words, by supplying cool water with a temperature lower than the body temperature to the bather and touching the bather's body with the cool water, heat is exchanged between the body surface of the bather and the cool water, thereby making the bather feel cool. Is disclosed.

  In order to give a cool sensation to the bather, the cool water mist is ejected to give a cool feeling as in the prior art, and the cool water mist exchanges heat with the body surface to take heat away. It is an effective means. However, in order to give a cool feeling by heat exchange, it is necessary to secure a necessary amount of water at a temperature lower than the body temperature that can exchange heat, so it is necessary to increase the particle size of the cool water mist, There was a need to increase the amount of ejection.

  Therefore, if it is cool down after the mist sauna as in the prior art, the body temperature of the bather after the mist sauna is very high, and there is also a situation where you want to get a quick and strong cool stimulus Therefore, in order to give a cool feeling to the bather, even if a large amount of water mist with a large particle size that can be seen by the bather is ejected, the bather after the mist sauna does not give a sense of incongruity. It can be said that it is impossible to give a good cool feeling unless a large flow rate is ejected with such a particle size.

  However, instead of after the mist sauna, the bather is simply bathed in the tub and feels like he wants to cool his head just because he can't climb, or he feels a little cool by sitting on the rim of the tub In other words, in a situation where you want to have a comfortable bathing like an open-air bath, this kind of control by heat exchange not only makes you feel uncomfortable, but the degree of coolness is too strong and uncomfortable. I found a problem. Specifically, for bathers who want to take a bath in an open-air bath-like environment, spraying a large amount of visible-sized cool water mist into the open-air bath is a rainy weather. Not only was the visual sensation not good, but the face and hair got wet, and I felt very uncomfortable and never gave a good sensation.

  In addition, after the mist sauna as in the prior art, the relative humidity in the bathroom has reached 100% and condensation has occurred in the bathroom, so moisture adhering to the body surface of the bather However, if you want to get a bathing environment like an open-air bath, unlike after a mist sauna, it will not cause any problems. Since the relative humidity is relatively low, introducing a technology that gives a cool feeling through heat exchange by injecting a large amount of cool water mist with a large particle size into this environment will add to the cool feeling due to heat exchange. The present inventors have found a phenomenon in which a strong cooling sensation is given, which is far from the comfort of an open-air bath, because this cool water mist vaporizes heat from the body.

  Furthermore, a large amount of large-sized cool water mist ejected for heat exchange enters the bathtub and lowers the temperature of the hot water, so that it can be immersed in hot water for a long time. There was also a problem that one of the good points of the open-air bath was spoiled.

  Therefore, an object of the present invention is to provide a bathroom air conditioner that is provided in a bathroom space that is a closed space and can provide a comfortable bathing environment such as an open-air bath to bathers. .

  The bathroom air conditioner according to the present invention is a bathroom air conditioner that controls the air conditioning of a bathroom space, and includes a mist ejecting means that ejects cool water mist to a bathtub area in which a bathtub is disposed, and an airflow adjustment that adjusts an airflow in the bathtub area. And a control means for controlling each of the mist ejection means and the airflow adjustment means, and the control means has a cool feeling operation mode that allows the bather on the bathtub side to experience a cool feeling. The mist ejecting means and the air flow adjustment so that the heat generated by the bath can be taken away from the bather on the bathtub side during the period of the cool sensation operation mode by generating the air current while ejecting the cool water mist to the bathtub area. Control means.

  According to the present invention, the airflow in the bathtub side space is adjusted while ejecting the cool water mist to the bathtub area, so that by applying the wind together with supplying the cool water mist to the bather taking a bath in the bathtub area, Heat can be quickly taken away from the bather's body by heat of vaporization, and the heat is taken away from the body by the heat of vaporization when the wind blows in an enclosed outdoor bathroom. You can get the same sensation as you get a comfortable cool feeling. In addition, because it is configured to give a cool feeling using the heat of vaporization, it is not necessary to spout visible water mist with a large particle size, and it is not necessary to spout a lot of it, so it is not necessary to spout a lot of it. You can create a cool atmosphere with a good atmosphere close to an extremely comfortable open-air bath, feel an unpleasant sensation of getting wet, or greatly reduce the temperature of hot water in the bathtub Can also solve the problem. Furthermore, if you continue to squirt cool water mist in a closed space such as a bathroom, it is not an open space, so it accumulates and the humidity gradually increases. While the cool feeling effect is reduced, it becomes a situation of giving an unpleasant feeling that it feels muggy as the humidity increases. However, in the present invention, the bathroom air conditioner is controlled so that the heat of vaporization is generated during the period of the cool feeling operation mode, so that the bather is continuously open and comfortable like an open-air bath. It can continue to give a cool feeling.

  In the bathroom air conditioner according to claim 2, the control means controls the ejection of the cool water mist by the mist ejection means so that the relative humidity in the bathtub area does not reach 100% during the execution of the cool feeling operation mode. It is. According to this aspect, while the cool water mist is ejected from the mist ejecting means, the relative humidity in the bathroom, which is a closed space, is controlled so as not to reach 100%, so it is surely vaporized from the body surface of the bather. The heat can be taken away and a pleasant cool feeling can be continuously given. Furthermore, since it is possible to suppress the feeling of sultry heat accompanying an increase in humidity, it is possible to continuously provide an exhilarating cool feeling environment like an outdoor outdoor bath.

  Further, in the bathroom air conditioner according to claim 3, the control means causes the air flow adjusting means to blow air to the bathtub area in accordance with the cool water mist jetting by the mist jetting means during execution of the cool feeling operation mode. The means and the airflow adjusting means are controlled. According to this preferable aspect, it is necessary to supply cool water mist to the bather immersed in the bathtub in order to provide comfort like an open-air bath. In order to supply cool water mist to bathers against this ascending current, measures such as increasing the particle size are necessary. However, doing so would also create an environment like an open-air bath in the rain, so in the present invention, it is configured to blow air toward the bathtub area in accordance with the eruption of cool water mist. It is what you are doing. In this way, the cool water mist is reliably supplied to the bather taking a bath in the bathtub without enlarging the particle size of the mist so that a cool feeling can be given by the heat of vaporization. Furthermore, since the heat of vaporization can be promoted by the airflow generated by blowing air, it is possible to give the bather a comfortable cool feeling as if they are receiving a breeze in an outdoor outdoor bath.

  Further, in the bathroom air conditioner according to claim 4, the air flow adjusting means includes a blower that sends air into the bathroom space, and a louver that adjusts the direction of the air sent from the blower, and the control means is a cool feeling driving In the mode, the louver is controlled to be directed to the bathtub region. According to this aspect, since the direction of the air sent out from the blower by the louver is directed to the bathtub area, in addition to being able to accurately supply cool water mist and airflow to the bathtub area to the bather, the bather quickly Heat can be taken away by heat of vaporization. Therefore, it is possible to easily and surely give the bather a comfortable cool feeling as if they are receiving a breeze in an outdoor outdoor bath.

  Further, in the bathroom air conditioner according to claim 5, the control means controls the mist ejection means so that the amount of ejection of the cool water mist fluctuates in order to suppress an increase in humidity due to the ejection of the cool water mist during the cool feeling operation mode. Is to control. According to this aspect, for example, intermittent ejection is performed so that the ejection amount of the cool water mist fluctuates, or the ejection amount is increased or decreased. It becomes possible to suppress across. In addition, since the amount of squirting of the cool water mist is ejected, the cool water mist supplied to the bather will also vary, so that the heat deprived from the bather by the heat of vaporization is also a variable situation. Become. As a result, it is possible to provide a comfortable cool feeling to the bather for a long time without blowing out a lot of cool water mist, and the effect of decreasing the heat of vaporization due to the increase in humidity in the bathroom and the heat of steam. Can also be eliminated. Furthermore, it is possible to produce many practically excellent effects such as giving a feeling of discomfort of wetting the human body and reducing the temperature of hot water in the bathtub. If the point mentioned above is demonstrated concretely, if a cool feeling stimulus will be given continuously and stably, a bather will become accustomed to the cool feeling stimulus, and it will be in the situation which is not satisfied unless it is a strong cool feeling stimulus. In particular, in the situation where the majority of the body is soaked in hot water, even if the cool water mist is ejected and the heat of vaporization is taken away, the bather is so cold because it is soaked in hot water. There was a tendency to strongly demand a lack of coolness stimulation due to lack of feeling. Therefore, in order to continue to provide a satisfying cool feeling stimulus, it is necessary to increase the particle size of the cool water mist or to eject a large amount of cool water mist. It will cause challenges. However, according to the present invention, it is possible to achieve an excellent characteristic effect in the present technology that it is possible to continue to give a comfortable cool feeling to the bather without causing such a problem.

  Further, in the bathroom air conditioner according to claim 6, the control means is configured to intermittently eject the cool water mist so that the amount of the cool water mist is varied, and the frequency of the cool water mist in the intermittent spray is the start of the cool feeling operation mode. The mist ejecting means is controlled so that the time region after the time region is less than the time region close to. According to this aspect, since it can be said that the time region near the start of the cool sensation driving mode is a time when a request to cool is generated in the bather, it is possible to match the request by increasing the frequency of spraying the cool water mist. it can. Also, it can be said that the humidity rise in the bathroom does not occur so much in the time zone after the spray of the cool water mist, so even if the cool water mist is jetted frequently, the effect of the heat of vaporization decreases as the humidity rises. There is no problem that it will end up, and it is also unlikely that it will create sultry heat. Therefore, it can be said that it is desirable to perform control according to the request of the bather. On the other hand, in the subsequent time domain, the request to obtain a strong cool feeling is thought to have been reduced due to the previous cool feeling stimulus, while the humidity in the bathroom has also increased due to the cool water mist ejection. It can be said. Therefore, it can be said that it is a suitable response from the viewpoint that reducing the frequency of ejection in order to suppress an increase in humidity continues to provide a cool feeling suitable for bathers. As is clear from the above, it is possible to perform the cool feeling control optimal for the bather's request and situation.

  Further, in the bathroom air conditioner according to claim 7, the mist ejecting means generates cool water mist by ultrasonic vibration. According to this aspect, since the cool water mist is generated by ultrasonic vibration, the particle size of the cool water mist can be further reduced, and it is possible to provide a refreshing outdoor bath sensation that is not a situation like rain, and in the bathroom. It is possible to make the particle size easy to promote vaporization by suppressing the increase in humidity of the bath, so that the heat of vaporization can be taken away from the body surface of the bather reliably and quickly without feeling uncomfortable feeling of getting wet. It is possible to provide a comfortable cool feeling environment as if it is in an open-air bath.

  The bathroom air conditioner according to claim 8 further comprises operation accepting means for accepting an operation instruction for the bathroom air conditioner and outputting an operation instruction signal to the control means. The operation accepting means is an instruction to start the cool feeling operation mode. In response to the start instruction receiving unit being operated, an operation instruction signal for instructing the control means to start the cool feeling driving mode is output to the control means, and the control means depends on the cool feeling driving mode. Control is started. According to this aspect, since the control means starts the control in the cool feeling operation mode in response to the operation of the start instruction receiving unit, the cool feeling can be experienced according to the bather's intention.

  In the bathroom air conditioner according to claim 9, the start instruction receiving unit does not receive the start instruction of the cool feeling operation mode when the predetermined condition is satisfied. According to this aspect, for example, when the bathroom temperature is low or when it is not preferable to perform the control in the cool feeling operation mode, such as immediately after bathing, the start of the cool feeling operation mode is limited so as not to give the bather an uncomfortable feeling. It becomes possible to.

  According to the present invention, there is provided a bathroom air conditioner that can provide a comfortable and comfortable cooling environment to a bathing bather as if they are in a bathroom in a closed space, as if they were in an outdoor outdoor bath. It is in.

The bathroom air conditioner which is this embodiment is comprised so that zone air-conditioning control (henceforth escape mode) and cool feeling driving mode (henceforth outdoor bath mode) control are possible.

  The escape mode is a control for constructing a perspiration zone that encourages the bather to perspire in a preset wash area and constructing a cool sensation zone that allows the bather to experience a refreshing feeling in the remaining area of the bathroom unit BR. . As a result, the bath unit BR is configured so that the bather can move between the sweat zone and the cool sensation zone, enabling the bather to cycle bathing that allows the bather to experience the perception of sweat and cool sensation alternately. Yes.

  The open-air bath mode is a mode that allows the bather to experience a cool feeling. More specifically, a fine cool water mist is attached to the bather, and the heat corresponding to the vaporization heat of the cool water mist is bathed. It is a mode that can be taken away from the person and feel a cool feeling. It should be noted that the cool water mist is not limited to the concept of spraying water or cold water as long as it is lower than the bather's body temperature and can feel a cool feeling after adhering to the bather. It is a mist having a temperature higher than the body temperature of the bather when it is ejected from the main body 10, and it is only required that the bather feels cool when cooled by being attached to the bather.

  As shown in FIG. 11, the main valve 80, the 1st water storage part 81, the mist heater 63a, the 2nd water storage part 83, and the drain valve 59 are connected in order from the upstream connected to the water supply. The first water reservoir 81 is provided with a float switch 82. When the water level in the first water storage unit 81 falls below a predetermined value, the float switch 82 is closed and the main valve 80 is opened. In response to the opening of the main valve 80, water is supplied to the first water reservoir 81. When the water level exceeds a predetermined water level, the float switch 82 is opened and the main valve 80 is closed.

  The water stored in the first water storage unit 81 is heated by the mist heater 63 a and supplied to the second water storage unit 83. An ultrasonic transducer 64 is provided on the bottom surface of the second water reservoir 83. The ultrasonic vibrator 64 vibrates in accordance with the instruction signal output from the CPU 40, and gives a fine vibration to the water stored in the second water reservoir 83 to generate mist.

  Subsequently, an example of incorporation into the bathroom air conditioner main body 10 using the piping shown in FIG. 11 is shown in FIG. FIG. 12 is a diagram schematically showing the internal configuration of the bathroom air conditioner body 10b. A bathroom air conditioner main body 10 b shown in FIG. 12 includes an air passage portion 105 and a cover portion 106. The air passage portion 105 includes a first air passage portion 105a, a second air passage portion 105b, a third air passage portion 105c, a fourth air passage portion 105d, and a fifth air passage portion 105e.

  The first air passage portion 105a, the second air passage portion 105b, and the third air passage portion 105c are connected to form an angle of 90 degrees with each other. Accordingly, the direction of the air sucked from the first air passage portion 105a and the direction of the air blown out from the third air passage portion 105c form an angle of 180 degrees.

  A circulation fan 531 is provided in the vicinity of the portion where the first air passage portion 105a and the second air passage portion 105b are connected. Circulation fan 531 is driven by circulation fan drive motor 53 that rotates based on an instruction signal from CPU 40 of bathroom air conditioner MS (see FIG. 3).

  A fourth air passage portion 105d is connected to a portion where the second air passage portion 105b and the third air passage portion 105c are connected. A circulation / ventilation switching damper 551a is provided in the fourth air passage portion 105d. The circulation / ventilation switching damper 551a is driven by a damper drive motor (not shown) that rotates based on an instruction signal from the CPU 40 of the bathroom air conditioner MS.

  Heating heaters 60, 61, and 62 are attached to the third air passage portion 105c. The energization state of the heaters 60, 61, and 62 is controlled by the switches 601, 611, and 621 that open and close based on an instruction signal from the CPU 40 of the bathroom air conditioner MS.

  A fifth air passage portion 105e is connected downstream of the heaters 60, 61, 62 of the third air passage portion 105c. A second water reservoir 83 (see FIG. 11) is connected to the fifth air passage portion 105e. When the circulation fan 531 is rotated to generate an air flow in the third air passage portion 105c, fine mist generated in the second water storage portion 83 is drawn into the third air passage portion 105c through the fifth air passage portion 105e. Mist is ejected from an opening 106a of a cover portion 106, which will be described later.

  The cover portion 106 is attached so as to cover the air passage portion 105. The cover portion 106 covers the air passage portion 105 and is attached in a state where a predetermined gap is secured between the flat ceiling portion 241 (see FIG. 1) of the ceiling member 24 of the bathroom unit BR. Accordingly, when the circulation fan 531 attached to the air passage portion 105 rotates, air is sucked from the gap between the cover portion 106 and the ceiling portion 241.

  An opening 105a is formed in a portion of the cover portion 106 corresponding to the third air passage portion 105c. The opening 105a is provided with two first movable louvers 501 and one second movable louver 511. The pair of first movable louvers 501 are attached immediately below the heaters 61 and 62. The second movable louver 511 is attached directly below the heater 60.

  Subsequently, the case where the bathroom air conditioner body 10 is installed in the bathroom unit BR and controlled in the open-air bath mode will be described with reference to FIGS. 13 and 14. In the example shown in FIG. 13, fine cool water mist is ejected from the mist nozzle 72 toward the bather H, and while the circulation fan 531 is stopped, the ventilation fan 551 is rotated to suck air from the louver 231a. It is a form. Thus, vaporization of the cool water mist adhering to the bather H is promoted by the air flow accompanying ventilation. Thus, a pleasant cool feeling is provided to the bather H, which corresponds to FIG. In this way, the air in the bathroom is exhausted by ventilation along with the ejection of the cool water mist, so that the accumulation of mist is suppressed, the increase in humidity is alleviated and heat is continuously taken away by the heat of vaporization. It is something that can be done. In addition, as is common to all the examples, as a fine cool water mist, a thing of about 5 microns is invisible, and on the other hand, it is good enough to take away heat by the heat of vaporization, and 20 microns. Is the maximum range that can be compromised. In order to generate the best mist of about 5 microns, the ultrasonic method is optimal including various factors such as noise.

  The example shown in FIG. 14 shows a modification, and the circulation fan 531 is rotated in addition to the ventilation fan 551. In this case, by rotating the ventilation fan 551, the heat corresponding to the heat of vaporization is taken from the bather H by the air flow accompanying ventilation as in FIG. 13, but in addition to this, the circulation fan 531 is rotating.

  The air flow created by rotating the circulation fan 531 is one of the purposes of taking the heat of vaporization from the bather H, but the main purpose is the hot water stretched around the bathtub BT. As a result, the upward airflow is generated in the upper space of the bathtub BT. By this updraft, the fine cool water mist made to maintain the atmosphere of the open-air bath can be prevented from falling by the updraft and will not reach the bather H, or it will take a lot of time to reach, In order to prevent the cool water mist from becoming hot or vaporizing, an air flow is created so that the cool water mist is reliably and quickly conveyed to the bather H. Therefore, it is not necessary to increase the amount of air blown, and if it is increased, not only noise but also a strong wind rather than a breeze will break down the atmosphere of a pleasant open-air bath sensation, and the heat of vaporization will be promoted too much Because it becomes.

  The first movable louver 501 and the second movable louver 511 are moved in accordance with the rotation of the circulation fan 531 so that the wind hitting the bather H is intermittent. Thus, the heat taken away from the bather H by the heat of vaporization is intermittently devised so as not to get used to the cool feeling stimulation. It is an image that reproduces the breeze that blows in the outdoor outdoor bath.

  Subsequently, cool feeling mode control using the bathroom air conditioner MS will be described. 15 and 16 are timing charts for explaining cool feeling mode control.

  In the first example shown in FIG. 15, when the control of the outdoor bath mode (cool feeling operation mode) is started, the circulation fan 531 is rotated at an extremely low speed to generate an airflow that looks like a breeze and the first movable louver. The air flow supplied to the bather is controlled to be intermittent by swinging the 501 and the second movable louver 511. Although the airflow is extremely low here, the rotation of the circulation fan 531 may be increased so that strong vaporization heat is generated only at the beginning of the outdoor bath mode. Moreover, fine cool water mist is ejected from the mist nozzle 72. By controlling in this way, the bather H is hit with a cool water mist riding in a cool breeze, and the bather H can experience a refreshing cool feeling.

  When a predetermined time (about 3 minutes) elapses after the start of cool sensation mode control, the request for a strong cool sensation is settled. Accordingly, the swing of the first movable louver 501 and the second movable louver 511 is also stopped. Here, the louver is supposed to swing all the way from the beginning, but it can be said that it is desirable to concentrate on the bather for the first minute and swing for the second half. Since the humidity in the bathroom unit BR has also increased when a predetermined time has elapsed after the start of cool sensation mode control, the rotation of the ventilation fan 551 is synchronized with the subsequent generation of cool water mist to generate airflow. The circulation fan 531 is switched to the ventilation fan 551. The purpose of this is to think that it is past the time zone in which a strong cool feeling stimulus is desired, and to suppress an increase in humidity in the bathroom unit BR. Therefore, the ventilation fan 551 functions as an airflow generation unit and a humidity increase suppression unit. The cool water mist is blown out and the ventilation fan 551 is rotated intermittently (1-minute injection, 1-minute stop cycle) to suppress the rise in humidity in the bathroom unit and to avoid getting used to the cool sensation caused by the heat of vaporization. Is given to bather H. Further, when the ventilation fan 551 is rotated, the humidity is reduced, so that it is possible to suppress the cloudy state in which the interior of the bathroom unit BR is filled with smoke due to the increase in humidity, and a refreshing feeling can be maintained. In this embodiment, the generation of the airflow by the ventilation fan 551 and the ejection of the cool water mist are synchronized, but the cool water mist is ejected and touches the body of the bather to vaporize it with the airflow. Because it is the purpose, it is not necessary to synchronize completely, and it is possible to shift the rotation of the ventilation fan so that it is slightly slower, or the start may be the same, but the end of the ventilation fan may be slightly delayed Needless to say.

  In the first example shown in FIG. 15, in the first time region close to the start of the open-air bath mode, the frequency of cool water mist is increased, and the circulation fan 511 is rotated to send out cool air, so that the bather H is refreshed. Gives a cool feeling. Thereafter, in the second time region, the rotation of the circulation fan 511 is stopped, and the supply of cool air to the bather H by the circulation fan 511 is stopped. Further, in the second time region, the cool water mist is ejected intermittently. Since the cool water mist is continuously ejected in the first time region near the start of the open-air bath mode, and the cool water mist is intermittently ejected in the subsequent second time region, the amount of the cool water mist ejected per unit time Is decreasing. However, in the second time region, since the air flow is generated by rotating the ventilation fan 551 in accordance with the ejection timing of the cool water mist, the bather H can feel a comfortable cool feeling.

  In the first example described above, in the second time region, the cool water mist is intermittently ejected and the ventilation fan 511 is intermittently rotated. However, the rise in humidity in the bathroom unit BR is suppressed, and a comfortable cool feeling is given to the bather H. The method of experiencing is not limited to this. For example, increasing the number of rotations of the ventilation fan 511 to generate fluctuations in the air volume is an example. Further, the circulation fan 511 may be intermittently rotated in the first time region. Control may be made such that the rotation of the circulation fan 511 is kept constant, the first movable louver 501 and the second movable louver 511 are swung, and the bather H in a certain place feels fluctuations in the airflow.

  In the second example shown in FIG. 16, when the control of the open-air bath mode (cool feeling operation mode) is started, the ventilation fan 551 is rotated from the beginning in addition to the rotation of the circulation fan 531. Part. The latter point is the same. By controlling in this way, the generation of airflow can be created by both the circulation fan 531 and the ventilation fan 551, so that a strong cool feeling stimulus can be created or the noise can be reduced by reducing the rotation of one fan. An effect can be obtained. Furthermore, the rotation of the ventilation fan 551 can suppress an increase in humidity accompanying the ejection of the cool water mist from the beginning, and the bather H can experience a refreshing cool feeling.

  When a predetermined time elapses after the cool feeling mode control starts, the rotation of the circulation fan 531 is stopped, and the first movable louver 501 and the second movable louver 511 are also stopped accordingly. In the subsequent ejection of the cool water mist, the rotation of the ventilation fan 551 is synchronized to suppress an increase in humidity in the bathroom unit BR. Therefore, the ventilation fan 551 functions as a humidity rise suppression means. The ejection of the cool water mist and the rotation of the ventilation fan 551 are continued intermittently to suppress an increase in humidity in the bathroom unit, and to give the bather H a cool feeling due to the heat of vaporization.

  In addition to the control pattern described above, it is also preferable to perform the following control pattern. One preferable aspect is an aspect in which the humidity in the bathroom is controlled to be in the vicinity of a predetermined value (for example, about 60%) based on the measurement value by the bathroom humidity sensor 48 installed in the bathroom unit BR. Another preferable aspect is an aspect in which the ventilation amount by the ventilation fan 551 is controlled so as to increase when the outside air humidity is high. This is because the heat taken away from the bather H by the heat of vaporization is increased to give a stronger cool feeling.

  Yet another preferred mode is a mode in which when the outside air temperature is low, control is performed so as to suppress the generation of air flow by reducing the amount of cool water mist ejected or suppressing the rotation of the circulation fan 551. This is because, when the outside air temperature is low, even if the heat taken away from the bather H is reduced, the bather H can experience a cool feeling.

  Yet another preferred mode is a mode in which the temperature and humidity in the bathroom unit BR are controlled to be always constant regardless of the state of the outside air. When the control is performed in this manner, a suitable cool feeling can be given to the bather H regardless of the seasonal variation.

It is possible to promote the evaporation of moisture from the body surface. Therefore, the bather H is deprived of heat corresponding to the heat of vaporization of water and can feel cool. Since the heat of vaporization is utilized, the amount of cool water mist touched by the bather H can be reduced, and the wind applied to the bather H can be set to a level that can promote the vaporization of water. Therefore, the bather H can feel a refreshing cool feeling, and the influence on the bathing environment can be reduced as much as possible.

  Moreover, in this embodiment, it is also preferable that CPU40 and the memory | storage part 41 control the ejection of the cool water mist by a mist ejection means so that the relative humidity in a bathtub area may not exceed 100% in an open-air bath mode (FIG. 15 and FIG. 15).

According to this control, since air is blown toward the bathtub region in accordance with the ejection of the cool water mist, the particle size of the cool water mist is generated even when hot water is applied to the bathtub BT and an upward airflow is generated. The water mist can reach the bather H who is bathing in the bathtub BT without increasing the size.

  Further, in the present embodiment, the airflow adjusting means includes a circulation fan 531 (blower unit) that sends out air into the bathroom space, and a first movable louver 501 and a second movable louver that adjust the direction of the air sent out from the circulation fan 531. 511, and the CPU 40 and the storage unit 41 control the first movable louver 501 and the second movable louver 511 to be directed to the bathtub area in the open-air bath mode. According to this control, since the direction of the air sent out from the circulation fan 531 by the first movable louver 501 and the second movable louver 511 is directed to the bathtub area, the wind direction can be accurately adjusted to the bathtub area, and the wind Can accurately feed the cool water mist into the bathtub area.

  Moreover, in this embodiment, CPU40 and the memory | storage part 41 are controlling the mist ejection means so that the ejection of a cool water mist may become intermittent ejection in the outdoor bath mode (refer description concerning FIG.15 and FIG.16). According to this control, since the cool water mist is intermittently ejected, an increase in humidity in the bathroom space can be suppressed. Moreover, since the cool water mist is ejected intermittently, the cool water mist that hits the bather H is also intermittent, and the bather H is intermittently deprived of heat corresponding to the heat of vaporization. Accordingly, the body temperature of the bather H is not lowered more than necessary, and the bather H can be given a moderate cool feeling.

  Moreover, in this embodiment, it is also preferable that CPU40 and the memory | storage part 41 control a mist ejection means so that the ejection frequency of the cool water mist in intermittent ejection may decrease with the passage of time from the start of the open-air bath mode ( (See description according to FIGS. 15 and 16). According to this preferred embodiment, the temperature of the cool water mist can be increased at the start of the outdoor bath mode, and the frequency of the cool water mist can be decreased with the passage of time. In a scene in which the frequency of squirting is increased and the degree of seeking a cool feeling is reduced thereafter, control according to the request of the bather H, such as decreasing the squirting frequency of the cool water mist, is possible.

  Moreover, in this embodiment, it is also preferable that a mist ejecting means produces | generates a cool water mist by ultrasonic vibration (refer description concerning FIG.11 and FIG.12). According to this preferable aspect, since the cool water mist is generated by ultrasonic vibration, the particle size of the cool water mist can be further reduced, and vaporization of the cool water mist can be promoted.

  Moreover, in this embodiment, the bathroom operation remote control 43 (operation reception means) which receives the operation instruction with respect to the bathroom air conditioner MS and outputs an operation instruction signal to the control means is provided. The outdoor bath mode button 43cf (start instruction receiving unit) that receives the start instruction of the outdoor bath mode is received, and the CPU 40 and the storage unit 41 start the open-air bath mode with respect to the operation of the outdoor bath mode button 43cf.
