Description

  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, it is possible to jet out cool water mist with water atomization for the purpose of lowering the temperature in the bathroom at an early stage and moderately, and also for providing a comfortable cool down after the mist sauna for bathers. The structure provided with the mist nozzle 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.

  Here, assuming that the conventional technology is applied to the cool down after the mist sauna, in order to give a cool feeling to the bather after the mist sauna accurately, the large-diameter cool water mist that can be seen by the bather. It is considered preferable to eject a large amount of gas. This is because the body temperature of the bather after the mist sauna is very high, and the bather after the mist sauna wants to obtain a rapid and strong cool stimulus. If it is a bather of such a situation, there is no sense of incongruity even if it takes a large amount of the above-mentioned large-diameter cool water mist. Can't get.

  On the other hand, rather than after the mist sauna, the bather is usually bathed in the bathtub, and the bather is sitting on the rim of the bathtub because he is not comfortable The present inventors have found that it is difficult to apply the above-described conventional technique in a situation where the user feels cool, in other words, in a situation where he / she wants to take a comfortable bath such as an open-air bath.

  The knowledge of the present inventors will be described more specifically as follows. That is, if a bather who wants to have a comfortable bath like an open-air bath is given a cool feeling by heat exchange as in the conventional technique, a large amount of large-diameter cool water mist is bathed. This gives a sense of incongruity or discomfort due to a soaked feeling or a too cool feeling.

  To elaborate the sense of incongruity and discomfort due to the soaking sensation, it is not possible to spout a large amount of visible large water mist for bathers who want to bathe in an open-air bath-like environment. Not only is the visual sensation not as good as an outdoor bath in the rain, but also the face and hair get wet and it is very uncomfortable and can never give a good sensation .

  The details of discomfort and discomfort due to too strong a cool feeling are as follows. After the mist sauna as in the prior art, the moisture in the bather's body surface is vaporized because the relative humidity in the bathroom reaches 100% and condensation occurs in the bathroom. Never do. Therefore, since it is an environment that cannot take heat of vaporization from the body, it is necessary to give a cool feeling by exchanging heat with water, so that a large amount of cool water mist is ejected and the bather is wet with cold water It is preferable to make it. On the other hand, when trying to realize a bathing environment such as an open-air bath, it is necessary to make the relative humidity relatively low unlike after a mist sauna, so the water adhering to the body surface of the bather tends to vaporize. Is in the situation. Introducing a technology that gives a cool feeling by heat exchange by spraying a large amount of large-diameter cool water mist to positively wet the bather, as after the mist sauna. In addition, when this cool water mist vaporizes, it takes heat away from the body, which gives a strong cool feeling stimulus that is far from the comfort of an open-air bath.

  Furthermore, a large amount of 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 new problem of spoiling one of the benefits of an open-air bath.

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

  The bathroom air-conditioning apparatus according to the present invention is a bathroom air-conditioning apparatus that controls the air-conditioning of a bathroom space, and includes a cool water mist spraying means that sprays cool water mist into the bathroom space, and air in the bathroom space is sucked into the bathroom space. Circulating air blowing means that blows and forms a circulating air flow in the bathroom space, ventilation means that sucks the air in the bathroom space and sends it out of the bathroom space, and forms a ventilation air flow in the bathroom space, cool water mist ejecting means, circulation Control means for controlling the air blowing means and the ventilation means, respectively, and the control means has a cool feeling operation mode in which a bather on the bathtub side can experience a cool feeling. In the cool feeling operation mode, the bathroom space Based on at least one of the temperature and humidity in the interior, the quantity characteristics for the amount of cool water mist ejected, the circulating airflow in the circulating airflow, and the ventilation airflow in the ventilating airflow are changed, and the bather It is configured to change the heat of vaporization to take al.

  The purpose of the present invention is to make the inside of the bathroom a pleasant and cool feeling environment so that bathing can be performed in a closed space inside the bathroom, like a very comfortable outdoor bath. It was difficult to create an atmosphere like an open-air bath because the temperature inside the bathroom was high, and it did not feel comfortable, unlike the outdoor wind. Therefore, the present inventors create a refreshing cold wind by mixing cool water mist in the blowing air in order to create a comfortable outdoor bath-like atmosphere even in a closed bathroom. At the same time, the cool water mist adhering to the body is further vaporized by the wind, and the heat is taken away at that time. In addition to lowering the temperature of the wind in this way, it is a structure that creates the optimal cool feeling using the heat of vaporization, so it makes the air blowing that makes the noise louder, or makes the water mist with a large particle size visible Since there is no need to squirt or cool water mist, it is possible to create a cool sensation environment with a good atmosphere close to an extremely comfortable open-air bath, rather than a rainy outdoor bath. Furthermore, it is possible to avoid an unpleasant sensation that the human body has become soaked or to greatly reduce the temperature of hot water in the bathtub.

  However, in order to create a very comfortable cooling environment within the pleasant sensation as described above, it is premised on that the mist and air are blown out to remove the heat of vaporization. Even if there is no problem when you are in a band, if there is no temperature or humidity condition in that band, you will feel a sense of discomfort or dissatisfaction with the fact that you can spray water on your body, and give a strong cool feeling The present inventors have found that since the heat of vaporization is used, it becomes a painful cool feeling or, on the contrary, it makes me feel a strong lack of cool feeling. Therefore, a cool feeling operation mode control for creating a cool feeling environment maintaining a more suitable atmosphere for practical use was studied.

  In detail, the temperature and humidity are naturally stable regardless of the bathing time and bathing conditions, but the bathroom is a closed and closed space. It changes to an extreme state that cannot be compared. Specifically, if it is outdoors, it is stable in winter when the temperature is low and humidity is low, and if it is summer, the temperature is high and humidity is slightly high. However, in a narrow bathroom, for example, immediately after bathing, there is no significant difference from the environmental conditions outside the bathroom, but after the bathing time has elapsed, the temperature and humidity rise as the hot water evaporates. Further, such a change in state is extremely different from a state where the bath is gently immersed in a bathtub, and a case where hot water is sprinkled in a situation such as using a shower, and the temperature and humidity are extremely different. In addition, the state that changes and recovers to the original state depends greatly on the environment outside the bathroom.In winter, the temperature and humidity rise is not extreme, Recovery to the state is quick because the outside air temperature and humidity are low. On the other hand, in summer, it rises extremely and recovers slowly.

  As understood from these things, if the cool water mist is blown or blown in the cool feeling operation mode control, if it is in a certain temperature range or humidity range, the atmosphere is good and the cool feeling is comfortable and it looks like an outdoor bath You can feel the atmosphere. However, in a situation where the temperature and humidity are low, in addition to a strong cool feeling by bathing in water, the wind temperature itself is low, so the cool feeling is further strengthened, and the heat of vaporization is also strong, giving a cool feeling that makes you feel painful. It will be. In addition, psychologically, in winter situations where the temperature and humidity are low, a cool feeling that is stronger than in the summer is not required. On the other hand, in situations where the temperature and humidity are high, bathers are psychologically demanding a strong cool feeling, and in addition to the situation where the temperature of the wind itself is high, the cool water mist is also warmed to the ambient temperature. It was difficult to lower the temperature of the water, and it was difficult for heat of vaporization to occur due to the high humidity, which resulted in a strong lack of cool feeling.

  There was also a problem from the viewpoint of the atmosphere, not the actual experience. Specifically, an exhilarating atmosphere in which the cool water mist cannot be seen at low temperatures may not give the feeling that it is cold, but on the other hand, the cool water mist can be seen a little in high temperatures It seemed preferable to give a cool and pleasant sensation in a foggy atmosphere, and from this point of view, the feeling of lack of coolness was given at high temperatures.

  Since the present invention changes the control law based on at least one of temperature and humidity in the bathroom space, it is always in the best form even in a bathroom environment that changes variously. It is possible to provide a bath-like atmosphere and an outdoor bath-like comfort as much as possible. Specifically, based on at least one of the temperature and humidity in the bathroom space, the amount characteristic for each of the squirting amount of the cool water mist, the circulating airflow in the circulating airflow, and the ventilation airflow in the ventilation airflow is changed from the bather. Since the control is performed so as to change the heat of vaporization, the atmosphere and comfort like an open-air bath can be provided regardless of the temperature band and humidity band in the bathroom space.

  The bathroom air conditioner according to claim 2 of the present application is configured to weaken the heat of vaporization taken from the bather when the temperature in the bathroom space is low. When the temperature in the bathroom space is low, the cool water mist is not warmed to the atmosphere temperature in the bathroom, and the temperature of the wind itself is low. Therefore, if you take the same vaporization heat from the bather as the vaporization heat that presupposes an average temperature range from this state, it feels too cold for the bather, so the vaporization heat taken away from the bather By weakening, the coolness control is optimal for such an environment, and the bather can enjoy the atmosphere and comfort of an open-air bath.

  When the temperature in the bathroom space is low, the bathroom air-conditioning apparatus according to claim 3 of the present application suppresses the amount of cool water mist to be ejected and gives a cool feeling mainly from at least one of the circulating air flow and the ventilation air flow to evaporate heat from the bather. It is configured to suppress the amount of deprivation. When the temperature in the bathroom space is low, the cool water mist is not warmed to the atmosphere temperature in the bathroom, and the temperature of the wind itself is low. In a situation where a lot of cool water mist is contained in this, not only does the wind temperature itself become too low to give an excessive cool feeling, but it also feels extremely cold due to excessive heat loss. Therefore, by controlling the amount of cool water mist ejected and giving a cool feeling mainly by the air flow, it becomes the optimal cool feeling control for such an environment, and the bather has the same atmosphere and comfort as an open-air bath. It is something that can be done. Moreover, since it can suppress feeling that the mist is seen or injected by suppressing the ejection amount of the cool water mist, the atmosphere can be further refreshed.

  The bathroom air conditioner according to claim 4 of the present application is configured to suppress the amount of the cool water mist ejected and increase at least one of the circulating air volume and the ventilation air volume when the temperature in the bathroom space is low and the humidity is high. . When the temperature in the bathroom space is low, the cool water mist is not warmed to the atmosphere temperature in the bathroom, and the temperature of the wind itself is low. In a situation where a lot of cool water mist is contained in this, not only does the wind temperature itself become too low to give an excessive cool feeling, but it also feels extremely cold due to excessive heat loss. On the other hand, the state where the humidity in the bathroom space is high is such that when the temperature is high as in the bathroom, it feels muddy and hot, so it tends to feel less cool than the low humidity state. On the other hand, when still injecting cool water mist in a high humidity state, in the environment of the present invention in which the humidity increases in an environment where the bather is not wet because the particle size of the cool water mist is small and the injection amount is small. In addition to giving a sultry heat, the feeling of exhilaration is lost and the atmosphere is destroyed, and further, it becomes difficult to take away the heat of vaporization due to an increase in humidity. If the temperature in the bathroom rises in this state, it becomes impossible to give a cool feeling due to the heat of vaporization, resulting in an unpleasant environment. Therefore, by suppressing the amount of cool water mist ejected, it is possible to maintain an environment where the increase in humidity is suppressed and heat of vaporization can be taken away, and a refreshing environment is maintained. By doing this, the cool feeling is strengthened. By doing so, it is possible to control the cool feeling optimal for such an environment, and the bather can enjoy the atmosphere and comfort of an open-air bath without change.

  When the humidity in the bathroom space is high, the bathroom air conditioner according to claim 5 of the present application increases the degree of cool feeling given to the bather by means other than taking the heat of vaporization in addition to taking the heat of vaporization from the bather. It is configured to let you. When the humidity in the bathroom space is high, it is in a state where it feels hot and humid when the temperature of the bathroom is high. Also, even when the bathroom temperature is not so high, it is difficult to give the bather a cool feeling that the bather feels comfortable by only the heat of vaporization when the humidity in the bathroom space is high. . Therefore, in the aspect according to this claim, in addition to taking away the heat of vaporization from the bather, the degree of coolness given to the bather is increased by means other than taking away the heat of vaporization such as positive heat exchange, so that the bather Since it is configured to give a cool feeling that is comfortable, the bather can enjoy the atmosphere and comfort of an open-air bath without change.

  The bathroom air conditioner according to claim 6 of the present application is configured to increase the degree of cool feeling given to the bather by increasing the ventilation air volume when the humidity in the bathroom space is high. When the humidity in the bathroom space is high, it is in a state where it feels hot and humid when the temperature of the bathroom is high. Also, even when the bathroom temperature is not so high, it is difficult to give the bather a cool feeling that the bather feels comfortable by only the heat of vaporization when the humidity in the bathroom space is high. . Therefore, in the aspect according to the present claim, in addition to imparting a cool feeling by depriving the heat of vaporization, a cool feeling by applying a wind to the bather can be given by increasing the ventilation air volume. Furthermore, since the humidity in the bathroom space can be lowered by increasing the ventilation air volume, it becomes possible to increase the heat of vaporization taken away from the bather, so that the bather has the same atmosphere as an open-air bath. You can enjoy the comfort.

  The bathroom air conditioner according to claim 7 of the present application is configured to increase the degree of cool feeling given to the bather by increasing the circulating air volume when the humidity in the bathroom space is high. When the humidity in the bathroom space is high, it is in a state where it feels hot and humid when the temperature of the bathroom is high. Also, even when the bathroom temperature is not so high, it is difficult to give the bather a cool feeling that the bather feels comfortable by only the heat of vaporization when the humidity in the bathroom space is high. . Therefore, in the aspect according to the present claim, in addition to imparting a cool sensation by depriving the heat of vaporization, a cool sensation by directly applying a wind to the bather can be given by increasing the circulation air volume. In this way, the circulating wind is a push-in wind, so it can directly hit the bather's body and give a stronger cool feeling, so the bather can enjoy the atmosphere and comfort like an open-air bath without changing. it can.

  The bathroom air conditioner according to claim 8 of the present application is configured to increase the degree of cool feeling given to the bather by increasing the amount of cool water mist ejected when the humidity in the bathroom space is high. When the humidity in the bathroom space is high, it is in a state where it feels hot and humid when the temperature of the bathroom is high. Also, even when the bathroom temperature is not so high, it is difficult to give the bather a cool feeling that the bather feels comfortable by only the heat of vaporization when the humidity in the bathroom space is high. . Therefore, in the aspect according to this claim, in addition to imparting a cool feeling by depriving the heat of vaporization, a large amount of the cool water mist can be attached to the bather to increase the amount of the cool water mist so that a cool feeling can be given by heat exchange. Since it is configured in this way, the bather can enjoy the atmosphere and comfort of an open-air bath without changing.

  The bathroom air conditioner according to claim 9 of the present application is configured to increase the amount of cool water mist ejected and increase at least one of the circulating air volume and the ventilation air volume when the temperature in the bathroom space is high. When the temperature in the bathroom space is high, it is considered that the demand for a bather to get a cool feeling becomes stronger. On the other hand, when the temperature in the bathroom space is high, if the amount of the cool water mist and the amount of air flow are the same as the amount of air jets based on the ideal temperature range, the bather will not be deprived of sufficient heat of vaporization. The same cool feeling cannot be felt physically and it cannot be felt comfortably. Therefore, by increasing the amount of cool water mist ejected, a lot of cool water mist adheres to the bather, and increasing the air volume effectively increases the heat of vaporization deprived from the bather. You can enjoy a pleasant atmosphere and comfort.

  The bathroom air conditioner according to claim 10 of the present application is configured to increase the ventilation air volume when the temperature in the bathroom space is high. When the temperature in the bathroom space is high, it is effective to lower the temperature in the bathroom space in order to effectively give the bather a cool feeling. Therefore, in the aspect according to this claim, by increasing the ventilation air volume, the hot air in the bathroom space is discharged, and the temperature in the bathroom space is lowered by sucking relatively cool outside air outside the bathroom space. Can do. By lowering the temperature in the bathroom space, it is possible to give a refreshing feeling to the bather, and as a result, the temperature rise of the cool water mist can also be suppressed, giving the bather a comfortable cooling feeling from these two viewpoints. It is possible to enjoy the atmosphere and comfort of an open-air bath.

  When the temperature and humidity in the bathroom space are high, the bathroom air conditioner according to claim 11 of the present application increases the amount of cool water mist ejected and the amount of circulating air, and directs the cool water mist and circulating air flow directly toward the bather. It spouts out to hit. When the temperature in the bathroom space is high, it is considered that the demand for a bather to get a cool feeling becomes stronger. On the other hand, when the temperature in the bathroom space is high, if the amount of the cool water mist and the amount of air flow are the same as the amount of air jets based on the ideal temperature range, the bather will not be deprived of sufficient heat of vaporization. The same cool feeling cannot be felt physically and it cannot be felt comfortably. Furthermore, when the humidity in the bathroom space is high, it may be extremely difficult to give a cool feeling only by taking the heat of vaporization from the bather. Therefore, in the aspect according to this claim, in addition to imparting a cool feeling by depriving the heat of vaporization, a large amount of the cool water mist is directly attached to the bather to increase the cool water mist and give a cool feeling by heat exchange. In addition to being configured so as to be able to provide a cool feeling by directly applying a wind to the bather by increasing the circulating air volume. Since it is configured to give a cool feeling to the bather from these two viewpoints, the cool feeling and the circulating airflow directly touched by the cool water mist was directly hit, while sacrificing the good outdoor bath atmosphere. You can feel a cool feeling.

  The bathroom air conditioner according to claim 12 of the present invention has a plurality of regions corresponding to the temperature and humidity in the bathroom space, and in each of the plurality of regions, the amount of cool water mist ejected, the amount of circulating air in the circulating airflow, and the amount of ventilation airflow A control map in which the ventilation air volume is predetermined is provided, and the control means, based on the control map, emits cool water mist in one area corresponding to the temperature and humidity in the bathroom space, the circulating air volume in the circulating air flow, and the ventilation The ventilation air volume in the airflow is specified, and the cool water mist ejecting means, the circulating air blowing means, and the ventilation means are controlled based on the identification result.

  In this aspect, in each of the plurality of areas corresponding to the temperature and humidity in the bathroom space, based on a control map in which the ejection amount of the cool water mist, the circulation air volume in the circulation airflow, and the ventilation airflow in the ventilation airflow are determined in advance. Since the control means performs the air conditioning control, it becomes easy to change the quantity characteristics for the cool water mist ejection means, the circulation air blowing means, and the ventilation means according to the temperature and humidity in the bathroom space. More specifically, when the temperature and humidity in the bathroom space can be acquired, an area on the control map corresponding to the temperature and humidity can be specified. Since each area on the control map has a corresponding amount of cool water mist ejected, circulating air flow, and ventilation air flow, if the area is specified, each of the cool water mist ejecting means, circulating air blowing means, and ventilating means You can decide how to control. Therefore, in addition to the region where the temperature and humidity bands in the bathroom space are ideal, even if there is a temperature and humidity in the bathroom space, the control can provide a comfortable and cool feeling as much as possible. Is possible.

  In the bathroom air conditioner according to claim 13 of the present application, the control means controls the air outside the bathroom to be taken into the bathroom space, and the bathroom temperature after a predetermined time after taking the air outside the bathroom and At least one of the humidity in the bathroom is estimated, and the cool water mist spraying means, the circulating air blowing means, and the ventilation means are controlled based on the estimation result. In the present invention, based on the state of at least one of temperature and humidity in the bathroom space, the amount characteristic for each of the amount of cool water mist ejected, the circulating air volume in the circulating airflow, and the ventilation airflow in the ventilation airflow is changed and taken away from the bather. Since the heat of vaporization is changed, control for converging the temperature and humidity in the bathroom space to the target values is not performed. Therefore, by estimating at least one of the temperature in the bathroom and the humidity in the bathroom after a predetermined time after taking in the air outside the bathroom, it is possible to determine how much the amount of chilled water mist, the circulating airflow in the circulating airflow, and the ventilation airflow in the ventilation airflow. It is possible to quickly determine whether to control, and based on the estimation result, it is possible to quickly and accurately control the cool water mist spraying means, the circulating air blowing means, and the ventilation means.

  In the bathroom air conditioner according to claim 14 of the present application, the control means performs ventilation by the ventilation means, measures at least one of a change in temperature and humidity in the bathroom space, and air outside the bathroom based on the measurement result. At least one of the temperature and humidity in the bathroom space after a predetermined time after the intake is estimated, and the cool water mist spraying means, the circulating air blowing means, and the ventilation means are controlled based on the estimation result. According to this aspect, at least one of the change in temperature and humidity in the bathroom space is measured, and at least one of the temperature and humidity in the bathroom space after a predetermined time after taking in the air outside the bathroom based on the measurement result. Since the estimation is performed, it is possible to estimate at least one of the temperature and the humidity in the bathroom space after a predetermined time by providing the measuring means only in the bathroom space. Therefore, the cool water mist ejecting means, the circulating air blowing means, and the ventilation means can be controlled with a simpler configuration.

  In the bathroom air conditioner according to claim 15 of the present application, the control means measures at least one of the temperature difference and the humidity difference inside and outside the bathroom space, and based on the measurement result, the bathroom after a predetermined time after taking in the air outside the bathroom. At least one of temperature and humidity in the space is estimated, and based on the estimation result, the cool water mist ejecting means, the circulating air blowing means, and the ventilation means are controlled. According to this aspect, since at least one of the temperature difference and the humidity difference inside and outside the bathroom space is measured, at least one of the temperature difference and the humidity difference inside and outside the bathroom space can be accurately obtained. Therefore, it is possible to control the cool water mist ejecting means, the circulating air blowing means, and the ventilation means more accurately.

  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.

  Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same constituent elements in the drawings will be denoted by the same reference numerals as much as possible, and redundant description will be omitted.

  The aspect which uses the bathroom air conditioner which concerns on embodiment of this invention is demonstrated referring FIG. FIG. 1 is a diagram for explaining an example in which a bathroom air conditioner body 10 constituting a bathroom air conditioner is attached to a bathroom unit BR.

  The bathroom unit BR is used when a bathroom is provided in an apartment house or a detached house, and is configured by assembling constituent members such as a wall, a floor, a ceiling, and a bathtub. The bathroom unit BR includes a floor member 20, wall members 21, 22 and 23, and a ceiling member 24. The wall members 21, 22, and 23 are attached upright around the floor member 20. The wall member 21 and the wall member 23 are provided at positions facing each other. The wall member 22 is provided adjacent to the wall member 21 and the wall member 23. Although not clearly shown in FIG. 1, a wall member is provided at a position facing the wall member 22, and the wall member is adjacent to the wall member 21 and the wall member 23. A ceiling member 24 is provided so as to face the floor member 20.

  The wall member 22 is provided with a counter portion 221 and a storage shelf 223. A shower faucet 222 is attached to the counter portion 221. The wall member 23 is provided with a door 231 for entering and exiting the bathroom unit BR. Although not clearly shown in FIG. 1, the door 231 is provided with a louver.

  The floor member 20 is provided with a bathtub BT. The bathtub BT has a bowl-like shape that forms a rectangular parallelepiped, and three walls among the four walls constituting the bathtub BT are arranged along the wall members 21 and 22 and a wall member that is not clearly shown in FIG. . Accordingly, one wall of the bathtub BT is erected in the vicinity of the substantially center of the floor member 20.

  The ceiling member 24 includes a flat ceiling portion 241 and a dome-shaped ceiling portion 242. The ceiling portion 241 is disposed substantially directly above the bathtub BT, and the ceiling portion 242 is disposed substantially directly above the floor member 20 where the bathtub BT is not provided. The bathroom air conditioner main body 10 is attached to the ceiling portion 241. The mist and wind blown from the bathroom air conditioner main body 10 are configured to be sent out to an intended part in the bathroom unit BR by a louver (not explicitly shown in FIG. 1).

  Subsequently, air conditioning control that can be realized by the bathroom air conditioner according to the present embodiment will be described. The bathroom air conditioner which is this embodiment is an apparatus which controls the air conditioning of the bathroom space in bathroom unit BR, Comprising: It is comprised so that cool feeling operation mode control (it is also called outdoor bath mode control, hereafter is the same) is possible. ing.

  Cool feeling driving mode control is a mode that allows a bather to experience a cool feeling. More specifically, a cool water mist is attached to the bather, and heat corresponding to the heat of vaporization of the cool water mist is applied. It is a mode that you can take away from the bather and experience a cool feeling. More specifically, the cool feeling operation mode control is a mode that provides a comfortable bathing environment such as an open-air bath to the bather, and is a mode in which the bather on the bathtub BT side can experience a cool feeling. In other words, in the bathroom space BR which is a closed space, like the outdoor outdoor bath, when the wind blows, the heat is taken away from the body by the heat of vaporization and a comfortable cool feeling is obtained. In this mode, you can get a sense.

  In addition, as fine cool water mist, about 3 to 5 microns is clearly not visible, but on the other hand, it is good enough to take away heat by vaporization heat, and up to 20 microns is the maximum range that can be compromised. I believe. In order to generate the best mist of about 3 to 5 microns, the ultrasonic method is optimal including various factors such as noise.

  FIG. 2 is a diagram for explaining cool feeling operation mode control. In FIG. 2, a bench BT1 is formed at one end of the rim of the bathtub BT, and a bench BT2 is formed inside the bathtub BT. Further, a bench counter 224 is provided on the wall surface opposite to the bathroom unit BR described in FIG. 1, and a mirror 225 is provided on the wall surface on which the bench counter 224 is provided. Further, a louver 232 is provided on a door (not explicitly shown in FIG. 2, but the door 231 in FIG. 1) below the washing unit side of the bathroom unit BR.

  A bathroom air conditioner body 10 is disposed above the bathtub BT. The bathroom air conditioner body 10 includes a circulation fan CF and a ventilation fan VF. The circulation fan CF sucks air in the bathroom unit BR and blows it into the bathroom unit BR, thereby forming a circulation air flow CC in the bathroom unit BR. The ventilation fan VF sucks the air in the bathroom unit BR and sends it out of the bathroom unit BR to form a ventilation air flow VC in the bathroom unit BR.

  Hot water is filled in the bathtub BT, and the bather H is taking a bath in the bathtub BT. When the bather H selects the cool sensation driving mode control, the cool water mist CM is ejected toward the washing area. In the case of FIG. 2, the circulation fan CF is also rotating, and a circulation airflow CC is formed. The circulating air flow CC is jetted toward the washroom floor, flows to the bathtub side along the washroom floor, and is then sucked into the bathroom air conditioner body 10. Therefore, the circulating airflow CC is constituted by a downward circulating airflow from the bathroom air conditioner body 10 toward the washing floor and a rising circulating airflow that circulates from the washing floor to the bathtub side and then circulates above the bathtub BT. .

  In the case of FIG. 2, the ventilation fan VF is also rotating, and the ventilation airflow VC is formed. The ventilation air flow VC flows from the louver 232 toward the inside air suction port (not explicitly shown in FIG. 2) of the bathroom air conditioner body 10, and is formed in parallel with the rising circulation air flow of the circulation air flow CC.

  The cool water mist CM is ejected toward the washing area, and is conveyed to the floor of the washing area by the descending circulating airflow of the circulating airflow CC. Thereafter, the descending circulating airflow is conveyed to the tub side of the cool water mist CM and then rises and is sucked into the bathroom air conditioner body 10. In addition, the ventilation air flow VC is sucked into the bathroom air conditioner main body 10 in parallel with the ascending circulation air flow carrying the cool water mist CM.

  Therefore, the cool water mist CM is conveyed by the airflow which goes to the upper part of the bathtub BT via the wash floor and contacts the bather H. The bather H does not take the cool water mist CM from above, but comes into contact with the cool water mist CM in a state of breeze blowing from the side or the bottom, so that it feels cool like a comfortable open-air bath. be able to.

  The mode illustrated in FIG. 2 is preferable as the cool feeling operation mode that can give a feeling like a comfortable outdoor bath, but the mode illustrated in FIG. 3 is also preferable when the bather H wants to obtain a stronger cool feeling.

  In the case of FIG. 3, when the bather H selects cool feeling driving mode control, the cool water mist CM is jetted toward the bathtub BT side. In the case of FIG. 3, the circulation fan CF is also rotating, and a circulation airflow CC is formed. Circulating airflow CC is jetted toward the bathtub BT side, circulates in the bathtub BT, and is then sucked into the bathroom air conditioner body 10.

  In the case of FIG. 3, the ventilation fan VF is also rotating, and a ventilation air flow VC is formed. The ventilation air flow VC flows from the louver 232 toward the inside air suction port (not explicitly shown in FIG. 2) of the bathroom air conditioner body 10.

  The cool water mist CM is ejected toward the bathtub BT and is conveyed to the bathtub BT by the circulating air current CC. Therefore, the bather H who is bathing in the bathtub BT can be sprayed directly, and a stronger cool feeling stimulus can be given to the bather H.

  Note that details of the jetting direction and amount of the cool water mist CM, and the forms of formation of the circulating airflow CC and the ventilation airflow VC will be described later.

  Subsequently, the bathroom air conditioner body 10 constituting the bathroom air conditioner MS will be described with reference to FIG. FIG. 8 is a diagram schematically showing the internal configuration of the bathroom air conditioner body 10.

  The bathroom air conditioner main body 10 includes an air passage portion 101 and a cover portion 102. The air passage portion 101 is connected to the first air passage portion 101a, the second air passage portion 101b, and the third air passage portion 101c. The first air passage portion 101a, the second air passage portion 101b, and the third air passage portion 101c are connected to form an angle of 90 degrees with each other. Therefore, the direction of the air sucked from the first air passage portion 101a and the direction of the air blown out from the third air passage portion 101c form an angle of 180 degrees. The air passage portion 101 has a fourth air passage portion 101d provided in parallel with the first air passage portion 101a. Further, the fifth air passage portion 101e is connected to the fourth air passage portion 101d, and the fourth air passage portion 101d and the fifth air passage portion 101e form an angle of 90 degrees with each other.

  A circulation fan CF is provided in the vicinity of the portion where the first air passage portion 101a and the second air passage portion 101b are connected. Circulation fan CF 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. 4).

  A ventilation fan VF is provided in the vicinity of the portion where the fourth air passage portion 101d and the fifth air passage portion 101e are connected. The ventilation fan VF is driven by a ventilation fan drive motor 55 that rotates based on an instruction signal from the CPU 40 of the bathroom air conditioner MS (see FIG. 4).

  Heating heaters 60, 61, and 62 are attached to the terminal portion of the third air passage portion 101c. The energization state of the heaters 60, 61, 62 is controlled by the switches 601, 611, 621 that open and close based on an instruction signal from the CPU 40 of the bathroom air conditioner MS (see FIG. 4).

  The cover portion 102 is attached so as to cover the air passage portion 101. The cover portion 102 covers the air passage portion 101 and is attached in a state where a predetermined gap G is secured between the flat ceiling portion 241 (see FIG. 1) of the ceiling member 24 of the bathroom unit BR. Therefore, when the circulation fan CF and the ventilation fan VF attached to the air passage portion 101 rotate, air is sucked from the gap G between the cover portion 102 and the ceiling portion 241. Accordingly, the gap G functions as an inside air suction port that is a suction port for air sucked by the ventilation fan CF and as an inside air suction port that is a suction port for air sucked by the circulation fan VF.

  An opening 102a is formed in a portion of the cover portion 102 corresponding to the third air passage portion 101c. A movable louver 501 is provided in the opening 102a. A mist nozzle 72 is provided in the vicinity of the movable louver 501. The mist nozzle 72 is attached to the washing area side with respect to the movable louver 501. Accordingly, the cool water mist CM ejected from the mist nozzle 72 is ejected from above the circulating airflow CC formed by the circulation fan CF and ejected from the movable louver 501. Therefore, the cool water mist CM is conveyed toward the washing floor by the circulating airflow CC.

  Subsequently, a case where the bathroom air conditioner main body 10 is installed in the bathroom unit BR and controlled in the open-air bath mode will be described with reference to FIGS. 9 and 10. The example shown in FIG. 9 relates to the cool feeling operation mode control described with reference to FIG. The example shown in FIG. 10 relates to the cool feeling operation mode control described with reference to FIG.

  In the example shown in FIG. 9, while circulating the cool water mist CM from the mist nozzle 72, the ventilation fan CF is rotated and the circulation airflow CC is formed. Since the movable louver 501 provided in the opening 102a, which is the outlet of the circulating airflow CC, is directed toward the washing area, the circulating airflow CC (downward circulating airflow CCd) is ejected toward the washing area. On the other hand, the mist nozzle 72 is provided on the washing area side with respect to the opening 102a, and cool water mist CM is jetted downward from the mist nozzle 72. Accordingly, the cool water mist CM is jetted into the circulating airflow CC (downward circulating airflow CCd), and the circulating airflow CC (downward circulating airflow CCd) is directed toward the floor of the washing place while carrying the coolwater mist CM.

  The circulating airflow CC (downward circulating airflow CCd) that has conveyed the cool water mist CM changes direction along the floor surface of the washroom and heads toward the bathtub BT. The circulating airflow CC toward the bathtub BT side rises so as to graze the upper end of the bathtub BT toward the gap G as the inside air suction port. This circulating airflow CC (ascending circulating airflow CCu) contacts the bather H to supply the cool water mist CM and take away the heat of vaporization from the bather H. Accordingly, the bather H does not take the cool water mist CM from above, but comes into contact with the cool water mist CM on the circulating airflow CC (upward circulating airflow CCu) that blows from the side or below. You can experience the comfort in an atmosphere close to an open-air bath.

  In the example shown in FIG. 9, the ventilation fan VF is also rotating. Since the louver 232 as an outside air suction port, which is an intake port for air sucked from outside the bathroom space in accordance with the rotation of the ventilation fan VF, is provided on the lower side of the washing place, the ventilation formed by the rotation of the ventilation fan VF. The air flow VC goes from the louver 232 to the gap G. Since the gap G of the bathroom air conditioner body 10 is provided above the bathtub BT and the louver 232 is provided below the washing area, the ventilation air flow VC from the louver 232 toward the gap G is parallel to the ascending circulation air flow CCu. Formed. Therefore, since the ventilation air flow VC also hits the bather H from the side or the lower side together with the ascending circulation air flow CCu, the heat of vaporization can be more effectively removed from the bather H.

  The example shown in FIG. 10 is an example in the case of giving a stronger cool feeling stimulus to the bather H than the example shown in FIG. In the example shown in FIG. 10, since the movable louver 501 provided in the opening 102a that is the outlet of the circulating airflow CC is directed toward the bathtub BT, the circulating airflow CC is ejected toward the bathtub BT. Yes. Further, a cool water mist CM is ejected downward from the mist nozzle 72. Therefore, the circulating airflow CC is directly blown to the bather H, and the cool water mist CM is also blown directly to the bather H because the floating distance is shortened.

  Subsequently, cool feeling operation mode control using the bathroom air conditioner MS will be described. Cool feeling operation mode control is based on the temperature and humidity conditions in the bathroom space, and the amount characteristics of each of the amount of mist of the cool water mist, the amount of circulating air in the circulating airflow, and the amount of ventilation airflow in the ventilation airflow , And the distribution value of the ventilation air volume) to change the heat of vaporization taken from the bather. More specifically, it has a plurality of areas corresponding to the temperature and humidity in the bathroom space, and in each of the plurality of areas, the ejection amount of the cool water mist, the circulation air volume in the circulation airflow, and the ventilation air volume in the ventilation airflow are predetermined. Control flow map, and based on the control map, specify the amount of cool water mist in one area corresponding to the temperature and humidity in the bathroom space, the circulation air flow in the circulation air flow, and the ventilation air flow in the ventilation air flow, Based on the specific result, the mist ejecting means, the circulating air blowing means, and the ventilation means are respectively controlled. An example of the control map is shown in FIG.

  The control map shown in FIG. 11 has a temperature axis on the horizontal axis and a humidity axis on the vertical axis, and has six regions (L1, L2, M1, M2, H1, and H2). The six regions are formed by dividing three zones (low temperature zone, medium temperature zone, high temperature zone) in the temperature axis direction and two zones (low humidity zone, high humidity zone) in the humidity axis direction. In the case of the present embodiment, the temperature and humidity inside and outside the bathroom are measured, and thus the applicable region is specified by the average value of the temperature and humidity inside and outside the bathroom.

  The region L1 is a low temperature / low humidity region. The region L1 assumes a normal bathing state in winter. In the region L1, the amount of cool water mist ejected is 0, the circulating air volume is small, and the ventilation air volume is 0. In addition, the direction of the circulation wind is the direction of the washing area. The reason why the amount of spray of the cool water mist is set to 0 is that it can be assumed that a cool feeling can be given without spraying the cool water mist because of the low temperature. The reason why the ventilation airflow is set to 0 is that no increase in humidity is expected because no cool water mist is ejected. The reason why the circulation air volume is small is that it is assumed that it is sufficient to give a little cool feeling because of the low temperature.

  The region L2 is a low temperature / high humidity region. The region L2 assumes that a long bath or shower is taken for a long time in winter. In the region L2, the amount of cool water mist ejected is 0, the circulating air volume is medium, and the ventilation air volume is 0. In addition, the direction of the circulation wind is the direction of the washing area. The reason why the amount of spray of the cool water mist is set to 0 is that it can be assumed that a cool feeling can be given without spraying the cool water mist because of the low temperature. The reason why the ventilation airflow is set to 0 is that no increase in humidity is expected because no cool water mist is ejected. The reason why the circulation air volume is set to be medium is that it is assumed that it is necessary to give a cool feeling stronger than the region L1 because of the low temperature but the high humidity.

  The region M1 is a medium temperature / low humidity region. The region M1 assumes a state where bathing is not performed for a long time in the season of the standard temperature range. In the area M1, the amount of cool water mist ejected is small, the circulating air volume is small, and the ventilation air volume is medium. Moreover, the direction of the circulating wind is the washing area, and the direction of the cool water mist is the washing area. The reason why the amount of eruption of the cool water mist is made small is that it is necessary to give a cool feeling by the cool water mist because it is not low temperature. The reason why the circulating air volume is small is that the amount of jet of the cool water mist is small, so from the viewpoint of circulating the cool water mist, a large amount of jet is not necessary, and the ventilation air volume is secured, so only the circulating air volume is vaporized. This is because it is not necessary to take away heat. The reason why the ventilation air volume is medium is that the rise of humidity can be expected to some extent because the cool water mist is ejected, and it is necessary to give the cool feeling stimulus by taking the heat of vaporization from the bather.

  The region M2 is a medium temperature / high humidity region. The region M2 is assumed to be in a relatively long bathing season in the standard temperature range season. In the region M2, the amount of the cool water mist ejected is medium, the amount of circulating air is medium, and the amount of ventilation air is large. Moreover, the direction of the circulating wind is the washing area, and the direction of the cool water mist is the washing area. The reason why the amount of eruption of the cool water mist is set to be medium is that it is necessary to give a relatively strong cool feeling by the cool water mist. The reason why the circulating air volume is set to the medium is that the amount of air blown out from the cool water mist requires a corresponding air volume from the viewpoint of circulating the cool water mist. The reason why the ventilation air volume is increased is that the rise of humidity can be expected to some extent because the cool water mist is blown out, and it is necessary to give the cool feeling stimulus by taking the heat of vaporization from the bather.

  The region H1 is a high temperature / low humidity region. The region H1 assumes a state where bathing is not so long in summer. In the region H1, the amount of cool water mist ejected is medium, the circulating air volume is medium, and the ventilation air volume is large. Moreover, the direction of the circulating wind is the washing area, and the direction of the cool water mist is the washing area. The reason why the amount of eruption of the cool water mist is set to be medium is that it is necessary to give a relatively strong cool feeling by the cool water mist. The reason why the circulating air volume is set to the medium is that the amount of air blown out from the cool water mist requires a corresponding air volume from the viewpoint of circulating the cool water mist. The reason why the ventilation air volume is increased is that the rise of humidity can be expected to some extent because the cool water mist is blown out, and it is necessary to give the cool feeling stimulus by taking the heat of vaporization from the bather.

  The region H2 is a high temperature / high humidity region. The region H2 assumes a state where bathing is long in the summer. In the region H2, the amount of cool water mist ejected is large, the circulating air volume is large, and the ventilation air volume is large. Moreover, the jet direction of the circulating wind is the bathtub direction, and the jet direction of the cool water mist is also the bathtub direction. The reason why the amount of eruption of the cool water mist is increased is that it is necessary to give the cool feeling very strongly by the cool water mist. The reason why the circulating air volume is increased is that the amount of squirting of the cool water mist is large, so that a corresponding air volume is necessary from the viewpoint of circulating the cool water mist, and it is necessary to apply the wind to the bather with the maximum air volume. Because there is. The reason why the ventilation air volume is increased is that it is necessary to apply the wind to the bather with the maximum air volume because it is high humidity and the cool water mist is blown out to suppress the increase in humidity as much as possible.

  Next, cool feeling operation mode control (open-air bath mode control) using the control map shown in FIG. 11 will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG. 12 is a flowchart illustrating a control process executed by the CPU 40 described with reference to FIG.

  It is determined whether the control start flag F is set (whether the value is 1) (step S01). If the control start flag F is set (if cool feeling operation mode control is started), the process proceeds to step S18 described later. If the control start flag F is not set (if the cool feeling operation mode control is not started), the process proceeds to step S02.

  An operation for starting the outdoor bath mode (cool feeling operation mode) is performed, and it is determined whether or not the outdoor bath mode is “ON” (step S02). If the outdoor bath mode is not “ON”, the process returns. If the outdoor bath mode is “ON”, the process proceeds to step S03.

  The temperature and humidity inside and outside the bathroom are measured, and the measured values are acquired (step S03). Specifically, the measurement values measured by the bathroom temperature sensor 44, the bathroom temperature sensor 45, the bathroom humidity sensor 46, and the bathroom humidity sensor 47 (see FIG. 4 above) are obtained, and the temperature inside and outside the bathroom is measured. Get a measurement of humidity. Subsequently, the process proceeds to step S04.

  Based on the measured value acquired in step S03, it is determined whether the bathroom temperature is in the low temperature zone (step S04). The low temperature zone is a temperature zone corresponding to the region L1 and the region L2 in FIG. If the temperature in the bathroom is not in the low temperature zone, the process proceeds to step S08 described later. If the temperature in the bathroom is in the low temperature zone, the process proceeds to step S05.

  Based on the measurement value acquired in step S03, it is determined whether the humidity in the bathroom is equal to or higher than a predetermined value and is in the high humidity band (step S05). The high humidity band is a humidity band corresponding to the region L2, the region M2, and the region H2 in FIG. If not in the high humidity band, the process proceeds to step S07 described later. If it is in the high humidity band, the process proceeds to step S06.

  As a result of the determination in step S05, if the humidity in the bathroom is in the high humidity band, the set amount corresponding to the region L2 in the control map shown in FIG. Is controlled (step S06). Then, it progresses to the process of step S17.

  As a result of the determination in step S05, if the humidity in the bathroom is in the low humidity band, the set amount corresponding to the region L1 in the control map shown in FIG. Is controlled (step S07). Then, it progresses to the process of step S17.

  As a result of the determination in step S04, when the temperature in the bathroom is not in the low temperature range, the stable state in the bathroom when the ventilation fan VF (see FIG. 2 etc.) is rotated for ventilation from the temperature difference inside and outside the bathroom. Is estimated (step S08). Subsequently, the process proceeds to step S09.

  Based on the humidity difference between the inside and outside of the bathroom, the humidity in the bathroom when the ventilation fan VF (see FIG. 2 etc.) is rotated for ventilation is estimated (step S09). Then, it progresses to the process of step S10.

  As a result of the estimation in step S09, it is determined whether the humidity at the stable time in the bathroom when the ventilation fan VF (see FIG. 2 and the like) is ventilated enters the high humidity band (step S10). The high humidity band is a humidity band corresponding to the region L2, the region M2, and the region H2 in FIG. If not in the high humidity band, the process proceeds to step S14 described later. If it is in the high humidity band, the process proceeds to step S11.

  As a result of the estimation in step S08, it is determined whether the humidity at the stable time in the bathroom when the ventilation fan VF (see FIG. 2 and the like) is ventilated enters the high temperature zone (step S11). The high temperature zone is a temperature zone corresponding to the region H1 and the region H2 in FIG. If the temperature in the bathroom is not in the high temperature zone, the process proceeds to step S13 described later. If the temperature in the bathroom is in the high temperature zone, the process proceeds to step S12.

  If the humidity in the bathroom is not in the high temperature range as a result of the determination in step S11, the amount of cool water mist ejected, the amount of circulating air flow, and the ventilation air flow are set at the set values corresponding to the region M2 in the control map shown in FIG. Is controlled (step S12). Then, it progresses to the process of step S17.

  If the result of determination in step S11 is that the humidity in the bathroom is in the high temperature range, the amount of cool water mist ejected, the amount of circulating air flow, and the ventilation air flow are set at the set values corresponding to the region H2 in the control map shown in FIG. Is controlled (step S13). Then, it progresses to the process of step S17.

  As a result of the determination in step S08, it is determined whether the humidity at the stable time in the bathroom when the ventilation fan VF (see FIG. 2 and the like) is ventilated enters the high temperature range (step S14). If the bathroom temperature is not in the high temperature zone, the process proceeds to step S16 described later. If the temperature in the bathroom is in the high temperature zone, the process proceeds to step S15.

  As a result of the determination in step S14, if the humidity in the bathroom is in the high temperature band, the set amount corresponding to the region H1 in the control map shown in FIG. Is controlled (step S15). Then, it progresses to the process of step S17.

  As a result of the determination in step S14, if the humidity in the bathroom does not fall within the high temperature range, the amount of cool water mist ejected, the amount of circulating air flow, and the ventilation air flow are set at the set values corresponding to the region M1 in the control map shown in FIG. Is controlled (step S16). Then, it progresses to the process of step S17.

  When the above-described control processing of step S06, step S07, step S12, step S13, step S15, and step S16 is executed, a control start flag F is set (step S17).

  If the control start flag F is set in step S01, it is determined whether an instruction to end the outdoor bath mode control is input (step S18). When the termination instruction for the open-air bath mode control is not input, the process proceeds to step S21 described later. If an instruction to end the outdoor bath mode control is input, the process proceeds to step S19.

  As a result of the determination in step S18, if an instruction to end the open-air bath mode control is input, the end control is performed, the spray of cool water mist is stopped, the circulation fan CF is stopped, and the ventilation fan VF is stopped (step S19). ). Subsequently, the process proceeds to step S20. When the control process of step S19 is executed, the control start flag F is returned to 0 (step S20).

  If the result of determination in step S18 is that an instruction to end open-air bath mode control has not been input, it is determined whether 5 minutes have elapsed since the start of open-air bath mode control (step S21). If 5 minutes have elapsed since the start of the open-air bath mode control, the process proceeds to step S25 described later. If 5 minutes have not elapsed since the start of the open-air bath mode control, the process proceeds to step S22. In addition, the process after this step S21 is performed in the case of the open-air bath mode control with cool down (refer FIG. 5).

  As a result of the determination in step S21, if 5 minutes have not elapsed since the start of the open-air bath mode control, the movable louver 501 is swung from the bathtub to the washing place (step S22). When the control is performed in the region H2 shown in FIG. 11, the movable louver 501 is fixed toward the bathtub. Subsequently, the process proceeds to step S23.

  The cool water mist is continuously ejected (step S23). The circulation fan CF and the ventilation fan VF are continuously rotated in accordance with the ejection of the cool water mist (step S24).

  As a result of the determination in step S21, if 5 minutes have elapsed since the start of the open-air bath mode control, the movable louver 501 is fixed toward the washing area (step S22). Subsequently, the process proceeds to step S26.

  The cool water mist intermittently ejects fluctuations (step S26). The circulation fan CF and the ventilation fan VF are rotated in accordance with the fluctuation of the cool water mist (step S27).

  Next, an example of controlling the rotation speed of the circulation fan CF and the ventilation fan VF will be described with reference to FIGS. 13 and 14. FIG. 13 is a diagram showing the rotation correction amount of the ventilation fan VF, and FIG. 14 is a diagram showing the rotation correction amount of the circulation fan CF.

  As shown in FIGS. 13 and 14, from the start of the outdoor bath mode control (t1) to 5 minutes later (t2), the rotation correction amount is set to 2, and the rotation speeds of the ventilation fan VF and the circulation fan CF are operated normally. 2 times the number of rotations. Thereby, a strong wind can be applied to the bather and a strong cool feeling stimulus can be given.

  Five minutes after the start of the open-air bath board control (t2), the rotation correction amount is set to 1, and the rotation speeds of the ventilation fan VF and the circulation fan CF are returned to the normal operation. Further, after a few minutes have passed (t3), the rotational speed of the ventilation fan VF is gradually increased so that the rotational correction amount is about 1.5. On the other hand, the rotational speed of the circulation fan CF is gradually decreased so that the rotation correction amount is about 0.3. Thus, after time t4, the operation is performed with the ventilation fan VF as the main and the circulation fan CF as the subordinate.

  Next, the particle size control of the cool water mist will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG. 15 is a flowchart illustrating the control process executed by the CPU 40 described with reference to FIG.

  It is determined whether the cool water mist button 43bg (see FIGS. 4 and 5) of the bathroom operation remote controller 43 (see FIGS. 4 and 5) has been operated (step S31). If the cool water mist button 43bg is operated, the process of step S32 is performed, and if the cool water mist button 43bg is not operated, the process of step S33 is performed.

  If the result of determination in step S31 is that the cool water mist button 43bg has been operated, control is performed so that the particle size of the cool water mist is 30 μm (step S32).

  If the result of determination in step S31 is that the cool water mist button 43bg has not been operated, it is determined whether open-air bath mode control is being performed (step S33). If the outdoor bath mode control is not performed, the process is terminated, and if it is performed, the process of step S34 is performed.

  If the outdoor bath mode control is performed as a result of the determination in step S33, it is determined whether the region H2 (FIG. 11) is being controlled (step S34). If the area H2 is controlled, the process proceeds to step S38. If the area H2 is not controlled, the process proceeds to step S35.

  As a result of the determination in step S34, if the area H2 is not controlled, it is determined whether it is within 5 minutes from the start of the open-air bath mode control (step S35). If it is not within 5 minutes from the start of the open-air bath mode control, control is performed so that the particle size of the cool water mist becomes 3 μm (step S36). On the other hand, if it is within 5 minutes from the start of open-air bath mode control, it controls so that the particle size of a cool water mist may be set to 5 micrometers (step S36). If the region H2 is controlled as a result of the determination in step S34, control is performed so that the particle size of the cool water mist becomes 10 μm (step S38).

  Subsequently, an example in which a dehumidifier is provided in the bathroom air conditioner body will be described with reference to FIG. FIG. 16 is a view showing a bathroom air conditioner body 80 provided with a rotary dehumidification rotor R as a dehumidifier.

  The bathroom air conditioner body 80 includes an air passage portion 801 and a cover portion (not shown in the figure). The air passage portion 801 is connected to the first air passage portion 801a, the second air passage portion 801b, and the third air passage portion 801c. The first air passage portion 801a, the second air passage portion 801b, and the third air passage portion 801c are connected so as to form an angle of 90 degrees with each other. Therefore, the direction of the air sucked from the first air passage portion 801a and the direction of the air blown from the third air passage portion 801c form an angle of 180 degrees.

  Heating heaters 60, 61, and 62 are attached to the terminal portion of the third air passage portion 101c. The energization state of the heaters 60, 61, 62 is controlled by the switches 601, 611, 621 that open and close based on an instruction signal from the CPU 40 of the bathroom air conditioner MS (see FIG. 4).

  The air passage portion 801 includes a ventilation air passage 801d and a regeneration air passage 801e. The ventilation air passage 801d is provided in parallel with the second air passage portion 801b, and ends of each other are connected. A damper 802 is provided between the ventilation air passage 801d and the second air passage portion 801b. When the damper 802 is opened, air flows from the second air passage portion 801b. The ventilation air passage 801d is connected to an exhaust duct (not shown).

  The reproduction air passage 801e is provided in parallel with the first air passage portion 801a. The regeneration air passage 801e is configured to send air sucked from the bathroom space to an exhaust duct (not shown).

  A circulation fan CF is provided in the vicinity of the portion where the first air passage portion 101a and the second air passage portion 101b are connected. Circulation fan CF 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. 4).

  A regeneration fan RF is provided in the regeneration air path 801e. The regeneration fan RF is driven by a regeneration fan drive motor (not shown) that rotates based on an instruction signal from the CPU 40 of the bathroom air conditioner MS.

  A rotary dehumidification rotor R is provided in the vicinity of the end of the first air passage portion 801a and the regeneration air passage 801e on the bathroom space side. The rotary dehumidification rotor R is configured to rotate around an axis between the first air path portion 801a and the regenerative air path 801e. The rotary dehumidification rotor R is a moisture adsorbing means, also called a desiccant rotor, and is configured to absorb moisture in the passing air. If warm air is passed through the portion that has absorbed the moisture, the absorbed moisture is removed. And is configured to play.

  A regeneration heater 803 is provided closer to the bathroom space than the rotating dehumidification rotor R of the regeneration air passage 801e. The regeneration fan RF is provided closer to the exhaust duct than the rotary dehumidification rotor R.

  When dehumidifying the interior of the bathroom space, the damper 802 is closed and the circulation fan CF is rotated. When the circulation fan CF is thus rotated, the air in the bathroom space passes through the first air passage portion 801a, so that the air in the bathroom space passes through the rotary dehumidification rotor R. Accordingly, the air in the bathroom space is dehumidified by the rotary dehumidification rotor R, and is sent out from the second air passage portion 801b to the third air passage portion 801 and jetted into the bathroom space.

  The rotating dehumidifying rotor R rotates during the dehumidifying operation in the bathroom space. Further, the regeneration heater 803 is energized and the regeneration fan RF also rotates. Therefore, the rotary dehumidification rotor R is regenerated by removing moisture in the regeneration air passage 801e, and can continue dehumidification of the air in the bathroom space passing through the first air passage portion 801a.

  In the bathroom air-conditioning apparatus MS according to the present embodiment described above, the circulating air flow CC and the ventilation air flow VC are generated while ejecting the cool water mist CM to the bathroom unit BR. Therefore, the cool water mist is given to the bather H taking a bath on the bathtub BT side. By applying the wind in conjunction with supplying CM, heat can be quickly taken away from the body surface of the bather H with heat of vaporization. Therefore, in the bathroom unit BR which is a closed space, like the outdoor outdoor bath, when the wind blows, the heat is taken away from the body by the heat of vaporization and a comfortable cool feeling is obtained. Obtainable. In addition, since it is configured to give a cool feeling by using the heat of vaporization, it is not necessary to eject a visible cool water mist CM having a large particle size, and it is not necessary to eject a large amount of cool water mist CM. It does not feel like a bath, but can create a cool atmosphere with a good atmosphere close to an extremely comfortable open-air bath. Furthermore, it is possible to avoid an unpleasant sensation that the human body has become soaked, or to greatly reduce the temperature of hot water in the bathtub BT.

  In addition, if you continue to blow out the cool water mist CM in a closed space such as a bathroom, it is not an open space, so it accumulates and the humidity gradually increases, making it difficult for water to evaporate and reducing the cool feeling effect due to heat of vaporization. In addition, in the environment of the present embodiment in which the humidity is increased in an environment where the bather H is not wet because the particle size of the cool water mist CM is small and the injection amount is small, the heat of steam is increased as the humidity increases. The situation gives a feeling of discomfort. As described above, the situation in which the bather H feels comfortable varies depending on the change in humidity, but the situation in which the bather H feels comfortable also varies depending on the change in temperature in the bathroom unit BR. On the other hand, in this embodiment, based on the state of at least one of the temperature and humidity in the bathroom unit BR, the amount with respect to each of the ejection amount of the cool water mist CM, the circulation air amount in the circulation air flow CC, and the ventilation air amount in the ventilation air flow VC. Since the heat of vaporization taken away from the bather H is changed by changing the characteristics, it is possible to avoid unpleasant situations such as sultry or chilly by taking away the heat of vaporization that the bather H feels comfortable. it can. Also, instead of controlling each amount by a simple control law, depending on the temperature and humidity of the bathroom unit BR, cool water mist ejection means (pump drive motor 54, mist pump 541, main valve 56, mist valve 57), Change the quantity characteristics (spout amount, circulating air volume, and ventilation air volume distribution value) for the circulating air blowing means (circulating fan drive motor 53, circulation fan CF) and ventilation means (ventilation fan drive motor 55, ventilation fan VF). Therefore, appropriate control according to the means that can be used is possible, and a comfortable bathing environment can be provided for the bather H.

  In the present embodiment, the purpose of the present invention is to make the bathroom unit BR a comfortable and cool environment so that the user can take a bath in a closed space in the bathroom unit BR as if it were a very comfortable outdoor bath. However, simply sending the air into the bathroom unit BR does not create a wind that feels comfortable unlike the outdoor wind because the temperature inside the bathroom unit BR is high. It was difficult to produce. Therefore, in order to create a comfortable outdoor bath-like atmosphere even in the bathroom unit BR, which is a closed space, a refreshing cold wind is created by mixing cool water mist CM in the blowing air, The cool water mist CM adhering to the body is further vaporized by the wind, and in order to take away heat at that time, it is devised so that a pleasant cool feeling similar to the outdoors can be given. In addition to lowering the temperature of the wind in this way, it is a structure that creates the optimal cool feeling using the heat of vaporization, so it makes the air blowing that makes the noise louder, or makes the water mist with a large particle size visible Since there is no need to blow out commercials or a large amount of cool water mist commercials, it is possible to create a cool atmosphere with a good atmosphere close to an extremely comfortable outdoor bath rather than a feeling like a rain outdoor bath. Furthermore, it is possible to avoid an unpleasant sensation that the human body has become soaked, or to greatly reduce the temperature of hot water in the bathtub BT.

  However, in order to create an extremely comfortable cool feeling environment within the pleasant sensation as described above, it is premised on that the cool water mist CM and the wind are blown to take away the heat of vaporization. Even if there is no problem when in the band or humidity band, if there is no temperature or humidity condition in the band, you will feel a sense of discomfort or dissatisfaction with being able to spray water on your body. It has been found that the use of heat of vaporization that strongly imparts a feeling of painful cooling, and conversely, it makes me feel a lack of strong cooling. Therefore, a cool feeling operation mode control for creating a cool feeling environment maintaining a more suitable atmosphere for practical use was studied.

  In detail, although the temperature and humidity are naturally stable regardless of the bathing time and bathing condition, the bathroom unit BR is a closed closed space, so the temperature and humidity conditions in the bathroom unit BR Turns into an extreme state that is not comparable to the outdoors. Specifically, if it is outdoors, it is stable in winter when the temperature is low and humidity is low, and if it is summer, the temperature is high and humidity is slightly high. However, in a narrow bathroom unit BR, for example, if it is immediately after bathing, there is not much difference from the environmental condition outside the bathroom unit BR. However, after the bathing time has elapsed, the temperature and humidity rise with the evaporation of hot water. Further, such a change in state is extremely different from a state where the bath is gently immersed in a bathtub, and a case where hot water is sprinkled in a situation such as using a shower, and the temperature and humidity are extremely different. In addition, the state of changing and recovering to the original state is greatly influenced by the environment outside the bathroom unit BR. In winter, the temperature and humidity increase is not extreme. Recovery to the state is quick because the outside temperature and humidity are low. On the other hand, in summer, it rises extremely and recovers slowly.

  As understood from these things, if the cool water mist CM is blown or blown in the cool feeling operation mode control, if it is in a certain temperature range or humidity range, the atmosphere is good and the cool feeling of the outdoor bath is comfortable. You can feel the atmosphere. However, in a situation where the temperature and humidity are low, in addition to a strong cool feeling by bathing in water, the wind temperature itself is low, so the cool feeling is further strengthened, and the heat of vaporization is also strong, giving a cool feeling that makes you feel painful. In particular. In addition, psychologically, in winter situations where the temperature and humidity are low, it does not require a cool feeling that is stronger than in summer, so there is a difference from the psychological requirements of such bathers H and it could not be said to be a favorable situation. . On the other hand, in a situation where the temperature and humidity are high, the bather H is psychologically seeking a strong cool feeling, and in addition to the situation where the temperature of the wind itself is high, the cool water mist CM is also warmed to the ambient temperature. For this reason, it is difficult to lower the temperature of the wind, and it is difficult to generate heat of vaporization due to high humidity.

  There was also a problem from the viewpoint of the atmosphere, not the actual experience. Specifically, an exhilarating atmosphere in which the cool water mist CM cannot be seen at low temperatures may not give the cold feeling, but conversely, the cool water mist CM can be seen a little in high temperatures. The feeling seemed to be cool and comfortable in a foggy atmosphere, and from this point of view, the feeling of lack of coolness was also given at high temperatures .

  Since this embodiment changes a control law based on the state of at least one of temperature and humidity in bathroom unit BR, even if it is the environment in bathroom unit BR which changes variously to bather H, it is always It is possible to provide the best possible atmosphere such as an open-air bath and the comfort of an open-air bath as much as possible. Specifically, based on the state of at least one of the temperature and humidity in the bathroom unit BR, the quantity characteristics for each of the amount of cool water mist CM ejected, the circulating air volume in the circulating air flow CC, and the ventilation air volume in the ventilation air flow VC are changed. Because it controls to change the heat of vaporization taken away from the bather H, it gives the atmosphere and comfort like an open-air bath whatever the temperature band and humidity band in the bathroom unit BR be able to.

  In this embodiment, when the temperature in bathroom unit BR is low, it is comprised so that the vaporization heat taken from bather H may be weakened. When the temperature in the bathroom unit BR is low, the cool water mist CM is not warmed to the atmosphere temperature in the bathroom unit BR, and the temperature of the wind itself is low, so that a sufficient cool feeling can be obtained. Therefore, if the same heat of vaporization is taken from the bather H as a premise of a temperature range having a more average state from this state, the bather H feels it is too cold for the bather H. By weakening the heat of vaporization, the coolness control is optimal for such an environment, and the bather H can enjoy the atmosphere and comfort of an open-air bath.

  In the present embodiment, when the temperature in the bathroom unit BR is low, the amount of spray of the cool water mist CM is suppressed, and at least one of the circulating air flow CC and the ventilation air flow VC is mainly used to give a cool feeling to the vaporizer H to evaporate heat. It is configured to suppress the amount taken. When the temperature in the bathroom unit BR is low, the cool water mist CM is not warmed to the atmosphere temperature in the bathroom unit BR, and the temperature of the wind itself is low, so that a sufficient cool feeling can be obtained. In a situation where a lot of cool water mist CM is included in this, not only does the wind temperature itself become too low to give an excessive cool feeling, but also the heat of vaporization is taken away and it feels quite cold. Therefore, by controlling the amount of spray of the cool water mist CM and giving a cool feeling mainly by the air flow, it becomes the optimal cool feeling control for such an environment, and the bather H has the same atmosphere and comfort as an open-air bath. It can be tasted. Moreover, since it can suppress feeling that mist can be seen or injected by suppressing the ejection amount of the cool water mist CM, it can be further refreshed in terms of atmosphere.

  In the present embodiment, when the temperature in the bathroom unit BR is low and the humidity is high, the amount of spray of the cool water mist CM is suppressed and at least one of the circulation air amount CC and the ventilation air amount VC is increased. When the temperature in the bathroom unit BR is low, the cool water mist CM is not warmed to the atmosphere temperature in the bathroom unit BR, and the temperature of the wind itself is low, so that a sufficient cool feeling can be obtained. In a situation where a lot of cool water mist CM is included in this, not only does the wind temperature itself become too low to give an excessive cool feeling, but also the heat of vaporization is taken away and it feels quite cold. On the other hand, the state in which the humidity in the bathroom unit BR is high is such that when the temperature is high as in the bathroom, it feels hot and humid, and therefore there is a tendency to feel a lack of coolness in a low humidity state. On the other hand, when still injecting the cool water mist CM in a high humidity state, in addition to giving a sultry heat, the refreshing feeling is lost and the atmosphere is destroyed, and further, it becomes difficult to take away the heat of vaporization due to the increase in humidity. If the temperature in the bathroom rises in this state, it becomes impossible to give a cool feeling due to the heat of vaporization, resulting in an unpleasant environment. Therefore, by suppressing the amount of the mist CM that cools the water, it is possible to keep the environment where it is possible to take away the heat of vaporization by suppressing the increase in humidity, and maintain an exhilarating environment. By increasing it, the cool feeling is strengthened. By doing in this way, it becomes cool control optimal for such an environment, and the bather H can enjoy the atmosphere and comfort like an open-air bath without changing.

  In the present embodiment, when the humidity in the bathroom unit BR is high, in addition to taking the heat of vaporization from the bather H, the degree of cool feeling given to the bather H by means other than taking the heat of vaporization is increased. It is configured. When the humidity in the bathroom unit BR is high, it becomes a state in which it feels hot and humid in a situation where the temperature in the bathroom unit BR is high. Further, even when the bathroom temperature is not so high, it is difficult to provide a cool feeling that the bather feels comfortable from the bather H only by the heat of vaporization when the humidity in the bathroom unit BR is high. It is. Therefore, in addition to taking heat of vaporization from bather H, bather H feels comfortable by increasing the degree of cool feeling given to bather H by means other than taking heat of vaporization such as positive heat exchange. Since it is configured to give a degree of coolness, the bather H can enjoy the atmosphere and comfort of an open-air bath without change.

  In the present embodiment, when the humidity in the bathroom unit BR is high, the degree of cool feeling given to the bather H is increased by increasing the ventilation air volume. When the humidity in the bathroom unit BR is high, it becomes a state in which it feels hot and humid in a situation where the temperature in the bathroom unit BR is high. In addition, even when the temperature in the bathroom unit BR is not so high, when the humidity in the bathroom unit BR is high, the bather H feels cool enough to feel comfortable only by the heat of vaporization. It is difficult to give. Therefore, in addition to imparting a cool feeling by taking away the heat of vaporization, the cool air feeling can be given by applying wind to the bather H by increasing the ventilation air volume. Furthermore, since the humidity in the bathroom unit BR can be reduced by increasing the ventilation air volume, it becomes possible to increase the heat of vaporization taken from the bather H, so that the bather H remains like an open-air bath. You can enjoy a pleasant atmosphere and comfort.

  In the present embodiment, when the humidity in the bathroom unit BR is high, the degree of coolness given to the bather H is increased by increasing the circulating air volume. When the humidity in the bathroom unit BR is high, it becomes a state in which it feels hot and humid in a situation where the temperature in the bathroom unit BR is high. In addition, even when the temperature in the bathroom unit BR is not so high, when the humidity in the bathroom unit BR is high, the bather H feels cool enough to feel comfortable only by the heat of vaporization. It is difficult to give. Therefore, in addition to imparting a cool feeling by taking away the heat of vaporization, the cool air feeling can be given by directly applying a wind to the bather H by increasing the circulation air volume. In this way, since the circulating air flow CC is a wind that pushes in, it directly hits the body of the bather H and can give a stronger cool feeling, so the bather H has the same atmosphere and comfort as an open-air bath. You can taste it.

  In this embodiment, when the humidity in the bathroom unit BR is high, the amount of cool feeling given to the bather H is increased by increasing the amount of spray of the cool water mist CM. When the humidity in the bathroom unit BR is high, it becomes a state in which it feels hot and humid in a situation where the temperature in the bathroom unit BR is high. Further, even when the temperature in the bathroom unit BR is not so high, when the humidity in the bathroom unit BR is high, the bather H gives a cool feeling that the bather feels comfortable only by the heat of vaporization. It is difficult. Therefore, in addition to imparting a cool feeling by taking away the heat of vaporization, it is configured so that a large amount of the cool water mist CM can be attached to the bather H and a cool feeling by heat exchange can be given to the bather H by increasing the ejection amount of the cool water mist CM. Therefore, the bather H can enjoy the atmosphere and comfort of an open-air bath.

  In the present embodiment, when the temperature in the bathroom unit BR is high, the ejection amount of the cool water mist CM is increased, and at least one of the circulation air volume and the ventilation air volume is increased. When the temperature in the bathroom unit BR is high, it is considered that the demand for the bather H to obtain a cool feeling becomes strong. On the other hand, when the temperature in the bathroom unit BR is high, if the amount of squirting of the cool water mist CM and the amount of air are the same as the amount of blasting assuming an ideal temperature range, the heat of vaporization for the bather H is taken away Without being able to feel the same cool feeling, you cannot feel comfortable. Therefore, by increasing the amount of spray of the cool water mist CM, a large amount of cool water mist adheres to the bather H, and by increasing the air volume, the heat of vaporization taken away from the bather H is effectively increased. You can enjoy the atmosphere and comfort of an open-air bath.

  In this embodiment, when the temperature in bathroom unit BR is high, it is comprised so that ventilation volume may be increased. If the temperature in the bathroom unit BR is high, it is effective to lower the temperature in the bathroom unit BR if the bather H is to be effectively cooled. Therefore, by increasing the ventilation air volume, high-temperature air in the bathroom unit BR can be discharged, and the temperature in the bathroom unit BR can be lowered by sucking relatively cool outside air outside the bathroom unit BR. By lowering the temperature in the bathroom unit BR, it is possible to give a refreshing feeling to the bather H, and as a result, it is also possible to suppress the rise in temperature of the cool water mist CM, so the bather H is comfortable from these two viewpoints. The bather H can enjoy the atmosphere and comfort of an open-air bath.

  In the present embodiment, when the temperature and humidity in the bathroom unit BR are high, the amount of spray of the cool water mist CM is increased and the circulating air volume is increased, and the cool water mist CM and the circulating air current CC are directly applied to the bather H. To erupt. When the temperature in the bathroom unit BR is high, it is considered that the demand for the bather H to obtain a cool feeling becomes strong. On the other hand, when the temperature in the bathroom unit BR is high, if the amount of squirting of the cool water mist CM and the amount of air are the same as the amount of blasting assuming an ideal temperature range, the heat of vaporization for the bather H is deprived. Without being able to feel the same cool feeling, you cannot feel comfortable. Furthermore, when the humidity in the bathroom unit BR is also high, it may be extremely difficult to give a cool feeling only by taking the heat of vaporization from the bather H. Therefore, in addition to imparting a cool sensation by depriving the heat of vaporization, it is configured so that a large amount of the cool water mist is directly attached to the bather H to increase the cool water mist CM, thereby providing a cool feeling by heat exchange. At the same time, the cooling air volume can be increased by increasing the circulating air volume so as to give a cool feeling to the bather H by direct air flow. From these two viewpoints, the bather H is designed to give a cool feeling, so the cool feeling and the circulating airflow directly touched by the cool water mist are directly hit, while sacrificing the good outdoor bath atmosphere. You can feel a cool feeling.

  In this embodiment, it has a plurality of areas corresponding to the temperature and humidity in the bathroom unit BR, and in each of the plurality of areas, the ejection amount of the cool water mist CM, the circulation air volume in the circulation air flow CC, and the ventilation air volume in the ventilation air flow VC Is provided with a predetermined control map, and the control means (CPU 40) circulates in the circulating airflow CC in the amount of jet of the cool water mist CM in one region corresponding to the temperature and humidity in the bathroom unit BR based on the control map. The air volume and the ventilation air volume in the ventilation air flow VC are identified, and based on the identification result, the cool water mist ejection means (pump drive motor 54, mist pump 541, main valve 56, mist valve 57), circulation air blow means (circulation fan drive) Motor 53, circulation fan CF) and ventilation means (ventilation fan drive motor 55, ventilation fan VF) Each control (see FIG. 11).

  In this aspect, in each of a plurality of areas corresponding to the temperature and humidity in the bathroom unit BR, the amount of the blast of the cool water mist CM, the amount of circulating air in the circulating airflow CC, and the amount of ventilation airflow in the ventilation airflow VC are determined in advance. Since the control means performs air-conditioning control based on the map, the cool water mist injection means (pump drive motor 54, mist pump 541, main valve 56, mist valve 57), circulating air blow according to the temperature and humidity in the bathroom unit BR It becomes easy to change the quantity characteristic for each of the means (circulation fan drive motor 53, circulation fan CF) and the ventilation means (ventilation fan drive motor 55, ventilation fan VF). Further, since the control map is determined in advance, air conditioning control that matches the characteristics of the bathroom unit BR is possible. Therefore, since the heat of vaporization taken from the bather is changed based on at least one of the temperature and humidity in the bathroom unit BR, the heat of vaporization that the bather H feels comfortable can be muggy and chilly. Such an unpleasant situation can be avoided.

  In the present embodiment, the control means (CPU 40) controls the air outside the bathroom to be taken into the bathroom unit BR, and the temperature inside the bathroom after a predetermined time after taking the air outside the bathroom unit BR and Estimate at least one of the humidity in the bathroom, and based on the estimation result, cool water mist ejection means (pump drive motor 54, mist pump 541, main valve 56, mist valve 57), circulation air blowing means (circulation fan drive motor 53, Circulating fan CF) and ventilation means (ventilation fan drive motor 55, ventilation fan VF) are controlled.

Therefore, since the heat of vaporization taken from the bather H is changed, the temperature and humidity in the bathroom unit BR are not controlled to converge to the target values. Therefore, by estimating at least one of the temperature in the bathroom and the humidity in the bathroom after a predetermined time after taking in the air outside the bathroom unit BR, the amount of the cool water mist CM ejected, the amount of circulation air in the circulation air flow CC, and the amount of ventilation air flow VC It is possible to quickly determine how to control the ventilation air volume, and based on the estimation result, cool water mist ejection means (pump drive motor 54, mist pump 541, main valve 56, mist valve 57), The circulation air blowing means (circulation fan drive motor 53, circulation fan CF) and the ventilation means (ventilation fan drive motor 55, ventilation fan VF) can be quickly and accurately controlled.

  In the present embodiment, the control means (CPU 40) performs ventilation by the ventilation means (ventilation fan drive motor 55, ventilation fan VF), measures at least one of temperature and humidity changes in the bathroom unit BR, and measures the measurement. Based on the result, at least one of the temperature and the humidity in the bathroom space after a predetermined time after taking in the air outside the bathroom unit BR is estimated, and based on the estimation result, the cool water mist ejecting means (pump drive motor 54, mist pump) 541, main valve 56, mist valve 57), circulation air blowing means (circulation fan drive motor 53, circulation fan CF), and ventilation means (ventilation fan drive motor 55, ventilation fan VF), respectively. According to this aspect, ventilation is performed to measure at least one of a change in temperature and humidity in the bathroom unit BR, and the inside of the bathroom space after a predetermined time after taking in the air outside the bathroom unit BR based on the measurement result. Since at least one of temperature and humidity is estimated, it is possible to estimate at least one of the temperature and humidity in the bathroom space after a predetermined time by providing the measuring means only in the bathroom unit BR. Accordingly, the cool water mist ejection means (pump drive motor 54, mist pump 541, main valve 56, mist valve 57), circulation air blowing means (circulation fan drive motor 53, circulation fan CF), and ventilation means (with a simpler configuration) The ventilation fan drive motor 55 and the ventilation fan VF) can be controlled.
