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 below describes a mist cooling device that uses a jet of cool water mist to provide a comfortable bathing environment when bathing in the summer. Specifically, as shown in paragraph No. 23, after using a mist sauna, simply relying on heat dissipation does not cause the temperature in the bathroom to drop quickly, and in particular, in the summer, the bather is uncomfortable. In some cases, the temperature of the bathroom can be lowered early and moderately, and a cool water mist with fine water can be sprayed for the purpose of providing the bather with a comfortable cool-down after the mist sauna. 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 allows heat exchange, so naturally the particle size of the cool water mist increases and It was also necessary to increase the amount of ejection.

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

  However, instead of after the mist sauna, the bather is simply bathed in the tub and feels like he wants to cool his head just because he can't climb, or he feels a little cool by sitting on the rim of the tub In other words, in a situation where you want to have a comfortable bathing like an open-air bath, this kind of control by heat exchange not only makes you feel uncomfortable, but the degree of coolness is too strong and uncomfortable. I found a problem. Specifically, for bathers who want to take a bath in an open-air bath-like environment, spraying a large amount of visible-sized cool water mist into the open-air bath is a rainy weather. I couldn't give a good feeling.

  In addition, after the mist sauna as in the prior art, the relative humidity in the bathroom has reached 100% and condensation has occurred in the bathroom, so moisture adhering to the body surface of the bather This is not a problem because it is an environment where it is not possible to evaporate and take heat away from the body by vaporization heat, but if you want a bathing environment like an open-air bath, unlike the mist sauna, relative humidity Since this is a relatively low environment, if a technology that gives a cool feeling by heat exchange by injecting a large amount of cool water mist with a large particle size into this environment is introduced in addition to the cool feeling by heat exchange, The present inventors have found a phenomenon in which a strong cooling sensation is given, which is far from the comfort of an open-air bath because the cool water mist vaporizes from the body surface when it is vaporized from the body surface.

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

  Therefore, in the present invention, in a bathroom space that is a closed space, the bather is provided with a comfortable bathing environment such as an open-air bath, and the bather is continuously bathed without increasing the amount of cool water mist. It aims at providing the bathroom air conditioner which can give a favorable cool feeling.

  A bathroom air conditioner according to the present invention is a bathroom air conditioner that controls the air conditioning of a bathroom space, and includes a mist ejection means that ejects a cool water mist into the bathroom space, an airflow adjustment means that regulates an airflow in the bathroom space, and a mist ejection And a control means for controlling the airflow adjusting means and the airflow adjusting means, respectively, and the control means has a cool feeling operation mode that allows the bather to experience a cool feeling. In the cool feeling operation mode, the cool water mist is placed in the bathroom space. Controls the mist spraying means and airflow adjustment means so that the heat generated by vaporization is removed from the bather during the period of the cool sensation operation mode and the amount of heat taken away by the heat of vaporization is changed by generating an airflow while blowing. To do.

  According to the present invention, since the airflow in the bathroom space is adjusted while the cool water mist is ejected, by applying the wind together with supplying the cool water mist to the bather in the bathroom space, The heat can be quickly taken away by the heat of vaporization, and it is in a bathroom that is a closed space. Like an outdoor outdoor bath, the heat is taken away from the body by the heat of vaporization when the wind blows. You can get the same feeling as you get.

  In addition, because it is configured to give a cool feeling using the heat of vaporization, it is not necessary to spout visible water mist with a large particle size, and it is not necessary to spout a lot of it, so it is not necessary to spout a lot of it. It is possible to create a cool atmosphere with a good atmosphere close to an extremely comfortable open-air bath, and to solve the problem that the hot water in the bath tub is cooled.

  Furthermore, if you continue to squirt cool water mist in a closed space such as a bathroom, the humidity will gradually increase because it is not an open space. In the present invention, the bathroom air conditioner is controlled so that the heat of vaporization is generated during the cool feeling operation mode. Therefore, it is possible to continuously give the bather a pleasant cool feeling like an open-air bath that is an open space.

  In addition, since the amount of heat taken away from the body by the heat of vaporization is controlled, it can provide a comfortable cool feeling to the bather without blowing out a lot of cool water mist, and accompanying an increase in humidity in the bathroom This solves the problem of reducing the effect of heat of vaporization and sultry heat. Furthermore, it is possible to achieve a practically excellent effect that the temperature of the hot water in the bathtub is not lowered. Specifically, if the amount of heat taken away by the heat of vaporization is continuously changed without being changed, the user gets used to the cool feeling stimulus that occurs when the heat is taken away, and the situation is such that the user is not satisfied unless the stimulus is a stronger cool feeling stimulus. Therefore, in order to continue to provide a cool feeling stimulus that satisfies the bather, it is necessary to squirt a lot of cool water mist and increase the amount of heat taken away by the heat of vaporization. As a result, the heat of vaporization accompanying an increase in humidity In addition to causing problems such as lowering the effect of the heat and giving a sultry heat rather than a cool sensation, it also causes a problem of lowering the temperature of the hot water in the bathtub. Without inviting, it is possible to continue to give a pleasant cool feeling to the bather.

  In the bathroom air conditioner according to the present invention, it is also preferable that the mist ejecting means ejects mist to at least the bathtub area where the bathtub is disposed, and the airflow adjusting means adjusts the airflow in at least the bathtub area. According to this preferred embodiment, since air current is generated while mist is ejected at least in the bathtub area, it is possible to apply a wind to the bather who is bathing in the bathtub area as well as touch the mist. It is possible to promote the evaporation of moisture from the body surface of the bather inside.

  In the bathroom air conditioner according to the present invention, it is also preferable that the control means controls the air flow adjusting means so as to vary the air flow in the bathroom space in the cool feeling operation mode. According to this preferred embodiment, since the airflow in the bathroom space is changed, the airflow that hits the bather fluctuates, and the amount by which the bather is deprived of heat corresponding to the heat of vaporization also fluctuates. Therefore, for example, it is possible to perform control so that the body temperature of the bather is not lowered more than necessary, and an appropriate cool feeling can be continuously given to the bather.

  In the bathroom air conditioner according to the present invention, it is also preferable that the control means controls the airflow adjusting means so that the airflow in the bathroom space is intermittently generated. According to this preferred embodiment, since the airflow is generated intermittently, the airflow hitting the bather is intermittent, and the bather is intermittently deprived of heat corresponding to the heat of vaporization. Therefore, the body temperature of the bather is not lowered more than necessary, and a moderate cool feeling can be continuously given to the bather.

  Moreover, in the bathroom air conditioner according to the present invention, the airflow adjusting means includes a blower that sends air into the bathroom space, and a louver that adjusts the direction of the air sent from the blower, and the control means includes air from the louver. It is also preferable to perform control so as to vary the adjustment direction. According to this preferred aspect, the direction of the air sent out from the blower by the louver is changed, so that the wind direction can be accurately adjusted to the intended area for the bather to feel a cool feeling and the wind is intended. Mist can be sent accurately to the area.

  In the bathroom air conditioner according to the present invention, it is also preferable that the control means controls the mist ejection means so as to vary the amount of mist ejected into the bathroom space in the cool feeling operation mode. According to this preferred embodiment, since the amount of mist ejected into the bathroom space is varied, the amount of mist that strikes the bather varies, and the amount by which the bather is deprived of heat corresponding to the heat of vaporization also varies. Therefore, for example, it is possible to perform control so that the body temperature of the bather is not lowered more than necessary, and an appropriate cool feeling can be continuously given to the bather.

  In the bathroom air conditioner according to the present invention, the control means may control the mist ejection means and the airflow adjustment means so that the amount of heat taken from the bather is reduced as time elapses from the start of the cool feeling operation mode. preferable. According to this preferred embodiment, the amount of heat taken from the bather can be reduced as time passes after the start of the cool-feeling driving mode, so the coolness is strongly demanded when the bather seeks a cooler feeling, and then the coolness is demanded. In a scene where the degree is reduced, it is possible to perform control in accordance with the request of the bather such as weakening the cool feeling.

  According to the present invention, since a cool feeling is given to the bather by the heat of vaporization, it is possible to give a pleasant and comfortable cool feeling as if standing up in an open-air bath, and to a bathing environment such as a decrease in the temperature of the hot water in the bathtub, for example. Therefore, it is possible to provide a bathroom air conditioner that can reduce the influence of the as much as possible.

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 cool water mist ejected from the bathroom air conditioner main body 10 and the wind to be sent out 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 comprised so that zone air-conditioning control (henceforth escape mode) and cool feeling driving mode (henceforth outdoor bath mode) control are possible.

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

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

The first water reservoir 81 is provided with a float switch 82. When the water level in the first water storage unit 81 falls below a predetermined value, the float switch 82 is closed and the main valve 80 is opened. In response to the opening of the main valve 80, water is supplied to the first water reservoir 81. When the water level exceeds a predetermined water level, the float switch 82 is opened and the main valve 80 is closed.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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