Description

  The present invention relates to a bathroom air conditioner with a mist function.

  2. Description of the Related Art Conventionally, there is known a bathroom air conditioner with a mist function having a mist function for spraying mist in a bathroom in order to enjoy a mist sauna bath together with a dry heating function for blowing only warm air into the bathroom. This type of bathroom air conditioner with a mist function includes a circulation fan for circulating the air in the bathroom, a heat exchanger for the bathroom for heating the air, and a mist spraying section for spraying hot water in the bathroom in a mist form. The humidification heating unit which has and the ventilation unit for ventilating the inside of a bathroom after using a bathroom are provided.

Also, the dressing room adjacent to the bathroom needs to be ventilated to prevent condensation, mold, etc. due to moisture from the bathroom, but a ventilation unit for the dressing room should be provided separately from the bathroom ventilation unit. However, the construction of the air conditioner becomes complicated, and it takes a lot of work to construct, and the cost of the entire equipment increases. For this reason, the ventilation unit of the bathroom and the bathroom communicate with each other through the bathroom communication passage, and the ventilation unit and the suction port of the dressing room communicate with each other through the communication passage for the dressing room. A bathroom air conditioner with a mist function that can ventilate a plurality of undressing rooms has been proposed (for example, FIG. 6 of Patent Document 1).
JP 2005-204713 A

  By the way, in the bathroom air conditioner with the mist function as described above, if the bathroom is ventilated during the humidifying and heating operation in which the mist is sprayed in the bathroom, the sprayed mist is discharged to the outside and the humidifying heating is performed. In general, during humidification heating operation, the bathroom communication path is closed with the opening and closing means provided in the bathroom communication path that connects the bathroom and the ventilation unit, so that mist is not discharged to the outside. Yes.

  On the other hand, in recent air conditioners, it is becoming mainstream that the ventilation fan is always ventilated and the house is ventilated for 24 hours. In order to maintain a good indoor environment, not only ventilation is performed, It is required to secure a certain amount of ventilation airflow. Accordingly, if not only the bathroom communication path but also the dressing room communication path is closed by the opening and closing means during the humidifying and heating operation, the total ventilation air flow is reduced, and it is not preferable to stop the ventilation of both rooms at the same time. For this reason, even during the humidifying and heating operation, the dressing room communication passage that communicates the normal dressing room and the ventilation unit is opened to ventilate the dressing room.

  However, if the dressing room is ventilated by continuous ventilation, cold air is drawn into the dressing room due to ventilation and the temperature of the dressing room decreases, so that the bather comes out to the dressing room after the humidification heating operation is finished in winter. When bathing, there is a problem that the bather tends to feel cold because of the temperature difference between the bathroom and the dressing room. In addition, when the dressing room is ventilated, when the humidifying and heating operation is finished and the bather comes out of the dressing room, the mist in the bathroom tends to flow into the dressing room. Since the ventilation air volume is kept constant in the constant ventilation operation, it is difficult to discharge the mist that has flowed into the dressing room at a stretch, so that there is a problem that the dressing room tends to get wet. In this case, it is conceivable to increase the number of rotations of the ventilation fan by manual operation after the humidifying and heating operation is completed. However, since cold air is sucked into the dressing room and the temperature is lowered, the feeling of cold air is enhanced. Further, the switching operation of the ventilation operation by the manual operation is complicated, and if the operation of the ventilation fan by the manual operation is forgotten, there is a possibility that disadvantages such as condensation in the dressing room and generation of mold cannot be avoided.

  The present invention has been made in view of the problems as described above. In a bathroom air conditioner with a mist function including a ventilation unit having a common ventilation fan for ventilating a bathroom and a dressing room, the common ventilation fan is constantly ventilated. Even if it is done, not only can it reduce the feeling of cool air when the bather comes out of the dressing room after the humidification heating operation is completed, but it can also sufficiently ventilate the bathroom and the dressing room, and also ensure a constant ventilation air volume An object of the present invention is to provide a bathroom air conditioner with a mist function.

The present invention includes a circulation fan for circulating the air in the bathroom, a heat exchanger for the bathroom for heating the air, and a humidification heating unit having a mist spraying section for spraying hot water in the bathroom in a mist form,
In the casing communicated with the bathroom and the dressing room by the bathroom communication path and the dressing room communication path, respectively, air is sucked from the bathroom and the dressing room through the bathroom communication path and the dressing room communication path, A ventilation unit having a common ventilation fan for exhausting to the outside;
A bathroom air conditioner with a mist function, comprising control means for controlling the operation of the humidifying and heating unit and the ventilation unit,
The common ventilation fan is always operated for ventilation,
A first opening / closing means for adjusting the opening degree of the bathroom communicating path is provided in the bathroom communicating path, and a second opening means for adjusting the opening degree of the changing room communicating path is provided in the undressing room communicating path. Opening and closing means are provided,
When the humidifying heating operation for spraying hot and cold water in a mist form in the bathroom is started, the control means decreases the opening degree of the communication passage for the bathroom by the first opening / closing means, and when the humidifying heating operation is completed, The first opening / closing means and the second opening / closing means increase the opening degree of the bathroom communication passage by the first opening / closing means and decrease the opening degree of the communication passage for the dressing room by the second opening / closing means. It is a bathroom air conditioner with a mist function that controls the opening and closing means.
According to the bathroom air conditioner with a mist function, when the humidifying and heating operation is started, the opening degree of the bathroom communication path is reduced by the first opening / closing means. This prevents the mist in the bathroom from being discharged to the outside. When the humidifying and heating operation ends, the opening degree of the bathroom communication path is increased by the first opening / closing means, and the opening degree of the dressing room communication path is decreased by the second opening / closing means. As a result, the ventilation air volume in the bathroom is increased and the ventilation air volume in the dressing room is reduced, so that even if the common ventilation fan is constantly ventilated, the mist in the bathroom is less likely to flow into the dressing room and the moisture in the dressing room In addition, the intake of cool air into the dressing room due to ventilation can be suppressed, and the bather's feeling of cool air can be reduced. And since the increase and decrease of the ventilation air volume in the bathroom and dressing room are automatically performed by the control means when the humidification heating operation is completed, troublesome ventilation operation by manual operation becomes unnecessary, and the dressing room of the dressing room due to forgetting ventilation operation is not necessary. An increase in moisture can be prevented. Furthermore, since the common ventilation fan is always operated for ventilation, it is possible to ensure ventilation from the dressing room during the humidifying heating operation and from the bathroom after the humidifying heating operation is completed. Thereby, a constant ventilation air volume can be ensured without increasing the rotation speed of the ventilation fan.

  The control means may control the second opening / closing means such that the second opening / closing means increases the opening degree of the communication passage for the dressing room after a predetermined time has elapsed from the end of the humidifying / heating operation. According to the bathroom air conditioner with the mist function, ventilation of the dressing room is stopped while the bather is in the dressing room after the humidifying heating operation is completed, and then the dressing room is ventilated after the bather leaves the dressing room. Therefore, the feeling of cool air when the bather uses the dressing room can be reduced and the dressing room can be sufficiently ventilated after use.

The dressing room further includes a human sensing means.
When the person sensing means does not sense a person in the undressing room, the control means increases the opening degree of the communication path for the undressing room by the second opening / closing means, and the person sensing means has a person in the undressing room. When the second opening / closing means is sensed, the second opening / closing means may be controlled by the second opening / closing means so as to reduce the opening of the communication passage for the dressing room. According to the bathroom air conditioner with the mist function, ventilation when the bather is using the dressing room can be suppressed depending on the presence or absence of the human sensing means. When some of the persons come out to the dressing room in the middle of the heating operation, it is possible to reduce the intake of cold air into the dressing room without ending the humidifying heating operation. Further, the ventilation of the dressing room can be controlled without setting the timer, and the feeling of cool air when the bather enters the dressing room before the humidifying heating operation can be reduced.

  Furthermore, the common ventilation fan may be operated at the same rotational speed during any of the regular ventilation operation, during the humidification heating operation, and after the humidification heating operation. According to the bathroom air conditioner with a mist function, a constant ventilation air volume is ensured by controlling the first opening and closing means and the second opening and closing means. There is no need to increase or decrease. For this reason, ventilation can be performed by simple control.

  According to the present invention, in a bathroom air conditioner with a mist function including a ventilation unit having a common ventilation fan for ventilating a bathroom and a dressing room, even if the common ventilation fan is always ventilated for 24 hours ventilation, humidification is performed. Mist function that not only reduces the feeling of cool air when the bather comes out of the dressing room after the heating operation is completed, but also can sufficiently ventilate the bathroom and the dressing room, and also ensure a constant ventilation air volume. An attached bathroom air conditioner can be provided.

Embodiments of the present invention will be described below with reference to the drawings.

The apparatus 1 includes a humidifying and heating unit 2 and a ventilation unit 3, and can humidify and heat the bathroom BR by the humidifying and heating unit 2 and ventilate the bathroom BR, the dressing room DR, and the toilet TR by the ventilation unit 3. I am doing so. Although the toilet TR can be ventilated independently by another air conditioner, the ventilation when the ventilation of the bathroom BR or the dressing room DR is stopped is also performed by ventilating the toilet TR with the ventilation unit 3. The decrease in the air volume can be compensated by the control of only one device 1.

  As shown in FIG. 2, the humidifying and heating unit 2 includes a circulation fan 5 and a bathroom in which hot water from the heat source unit 6 is circulated in a casing 4 having a suction port and a blowout port (not shown) communicating with the bathroom BR. The heat exchanger 7 is housed. Further, the humidifying and heating unit 2 is provided with a nozzle N that sprays hot water in a mist state adjacent to the lower portion of the casing 4. The humidifying and heating unit 2 heats the air by the bathroom heat exchanger 7 while circulating the air in the bathroom BR by the operation of the circulation fan 5 to heat the bathroom BR and mists the hot water from the nozzle N. It is comprised so that humidification heating operation may be performed by spraying in a shape. The hot water for mist may be sprayed directly into the bathroom BR from a nozzle N connected to a mist heat exchanger (not shown) which is a liquid-liquid heat exchanger, or a heat exchanger for mist. The nozzle N connected to the pipe is disposed in the upper part of the bathroom heat exchanger 7, and hot water is diffused from the nozzle N to the bathroom heat exchanger 7 to generate mist, which is transported air formed by a circulation fan. The mist may be sprayed into the bathroom BR by being conveyed by the A variable louver 8 driven by a stepping motor 8 a is provided at the outlet of the casing 4 so that the direction of air blown from the humidifying and heating unit 2 can be changed by the variable louver 8. Further, in the hot water circulation path 9 between the heat source device 6 and the bathroom heat exchanger 7, a thermal valve 10 for intermittently supplying hot water to the bathroom heat exchanger 7 is interposed. The motor 5a, the stepping motor 8a, and the thermal valve 10 of the circulation fan 5 are controlled by a controller 11 that is a control means including a microcomputer.

  The ventilation unit 3 includes a casing 12 adjacent to the casing 4 of the humidifying and heating unit 2 and a common ventilation fan 13 housed in the casing 12 and driven by a motor 13a (controlled by the controller 11). . The casing 12 includes a bathroom inlet 14 that communicates with the bathroom BR via the casing 4 of the humidifying and heating unit 2, and a dressing room and toilet inlets 15 and 16 that communicate with the dressing room DR and the toilet TR, respectively. And an exhaust port 17 communicating with the outside through the duct 17a. The common ventilation fan 13 is operated to suck air from the air inlets 14, 15, and 16 for the bathroom, the dressing room, and the toilet, and exhaust the air through the exhaust port 17. Ducts 18 and 19 communicating with the dressing room DR and the toilet TR are connected to the inlets 15 and 16 for the dressing room and the toilet through pipe joints 20 and 21 attached to the outer surface of the casing 12, respectively. ing. With the above configuration, the communication passage Pb for the bathroom that connects the bathroom BR and the ventilation unit 3 by the suction port of the casing 4 and the suction port 14 for the bathroom, the suction port of the dressing room DR, the duct 18, the pipe joint 20, and the dressing room The undressing room communication path Pd that communicates the undressing room DR and the ventilation unit 3 with the intake port 15, and the toilet TR and the ventilation unit 3 with the suction port, the duct 19, the pipe joint 21, and the toilet intake port 16 of the toilet TR A toilet communication passage Pt is formed.

  In the present embodiment, the bathroom communication path Pb that connects the bathroom BR and the ventilation unit 3 is provided with a bathroom variable damper 22 as a first opening / closing means at the bathroom air inlet 14 at the downstream end thereof. The bathroom variable passage 22 allows the bathroom communication path Pb to be opened and closed and its opening degree adjustable. Also, in the communication passages Pd and Pt for the dressing room and the toilet, the variable dampers 23 and 24 for the dressing room and the toilet, which are second and third opening / closing means, are provided in the intake ports 15 and 16 at the downstream ends thereof. Are provided, and the variable dampers 23 and 24 allow the communication paths Pd and Pt to be freely opened and closed and adjusted in opening. These variable dampers 22, 23, 24 are driven by stepping motors 22a, 23a, 24a controlled by the controller 11. Thereby, the opening degree of each of the variable dampers 22, 23, 24 for the bathroom, the dressing room, and the toilet, that is, the opening degree of each communication path Pb, Pd, Pt for the bathroom, the dressing room, and the toilet. Is adjusted according to a command signal from the controller 11.

  The controller 11 receives a signal from the remote controller 25 installed in the bathroom BR and a remote controller 26 installed in the dressing room DR and a signal from the toilet switch 27. The remote controls 25 and 26 are provided with various switches such as a constant ventilation switch, a humidifying / heating switch, a drying switch, a bathroom ventilation switch, and a dressing room ventilation switch. The controller 11 is connected to the humidifying / heating unit 2 according to the operation of these switches. The operation with the ventilation unit 3 is controlled. For example, when the continuous ventilation switch is turned on, the common ventilation fan 13 is continuously operated at a predetermined rotational speed with the variable dampers 22, 23, 24 for bathroom, undressing room, and toilet opened to a predetermined opening. Ventilation operation is performed. When the humidifying / heating switch is turned on, the heat source unit 6 is activated, the thermal valve 10 is opened, hot water is supplied to the bathroom heat exchanger 7, and the circulation fan 5 is activated. When the hot water circulating in the bathroom heat exchanger 7 is heated to a predetermined temperature, the hot water is sprayed in a mist form from the nozzle N, and the humidification heating operation is performed. When the bathroom ventilation switch and the dressing room ventilation switch are turned on, the bathroom variable damper 22 and the dressing room variable damper 23 are opened at a predetermined opening and the common ventilation fan 13 is activated to ventilate the bathroom BR and the dressing room DR. Is called. When the toilet switch 27 is turned on, the illumination of the toilet TR is turned on. At the same time, the toilet variable damper 24 is opened at a predetermined opening and the common ventilation fan 13 is operated to ventilate the toilet TR.

  Next, control in the ventilation unit 3 when the humidification heating switch is turned on during the regular ventilation operation will be described. During the regular ventilation operation, the common ventilation fan 13 is operated by a control signal from the controller 11, and the opening degree of each variable damper 22, 23, 24 is adjusted so as to ensure a constant ventilation air volume, Ventilation of each room is performed via each communication path Pb, Pd, Pt.

  When the humidifying / heating switch is turned on during the normal ventilation operation and the humidifying / heating operation is started, as shown in the flowchart of FIG. 3, the stepping motor 22a is operated, and the bathroom communication path Pb is opened by the bathroom variable damper 22. Close (S1). Then, it is determined whether or not the ventilation air volume by the ventilation unit 3 is equal to or greater than the set value (S2). If the ventilation air volume is less than the set value, the stepping motors 23a and 24a are operated to change the variable damper 23 for the dressing room. And the toilet variable damper 24 increase the opening degree of the dressing room communication path Pd and the toilet communication path Pt (S3). Therefore, the reduction of the ventilation air flow due to the bathroom communication path Pb being closed by the bathroom variable damper 22 results in the changing room communication path Pd and the bathroom communication path Pt between the dressing room variable damper 23 and the toilet variable damper 24. Thus, the ventilation air volume can be maintained at a set value or higher without increasing the rotational speed of the common ventilation fan 13. The ventilation air volume by the ventilation unit 3 may be obtained by map search using the rotation speed of the common ventilation fan 13 and the current of the motor 13a as parameters, or an air volume sensor is provided at the exhaust port 17 to directly detect the ventilation air volume. May be.

  And if the opening degree of each communicating path Pb, Pd, Pt is adjusted, the driving | operation of the heat source machine 6 will be started, the thermal valve 10 will be opened, and warm water will be supplied to the heat exchanger 7 for bathrooms, Is heated to a predetermined temperature, the circulation fan 5 is operated and hot water is sprayed from the nozzle N in a mist form (S4). At this time, since the bathroom communication path Pb is closed by the bathroom variable damper 22 as described above, the mist is prevented from being discharged to the outside.

  Next, the humidifying / heating switch of the remote controller 25 in the bathroom BR is turned off (S5), and when the humidifying / heating operation is completed, the operation of the heat source unit 6 is stopped, the heat valve 10 is closed, and the heat exchanger for the bathroom is used. The supply of hot water to 7 is stopped, the circulation fan 5 is stopped, and the spraying of mist from the nozzle N is stopped (S6). Further, in order to prevent the mist in the bathroom BR from flowing into the dressing room DR and to discharge the mist in the bathroom BR at an early stage, the stepping motor 22a is operated and the bathroom communication path Pb is opened by the bathroom variable damper 22. While opening, the stepping motor 23a is operated and the dressing room communication path Pd is closed by the dressing room variable damper 23 (S7). Then, it is determined whether or not the ventilation air volume by the ventilation unit 3 is equal to or greater than the set value (S8). If the ventilation air volume is less than the set value, the stepping motor 24a is activated and the toilet variable damper 24 is used for the toilet. The opening degree of the communication path Pt is increased (S9). Accordingly, since the ventilation of the dressing room DR is stopped by closing the dressing room communication path Pd by the variable damper 23 for the dressing room, the intake of cold air to the dressing room DR is reduced, and the bather can take off the dressing room. It is possible to reduce the feeling of cool air when coming out to the DR and to prevent mist from flowing out of the bathroom. Since the decrease in the ventilation air volume due to the closing of the dressing room variable damper 23 is compensated by the increase in the opening of the bathroom variable damper 22 and the toilet variable damper 24, the rotational speed of the common ventilation fan 13 need not be increased. The ventilation air volume can be maintained above the set value.

  When the opening degree of each of the variable dampers 22, 23, 24 is adjusted, the timer in the controller 11 is started and the timer display portion of the remote control 26 in the undressing room is turned on to stop ventilation in the undressing room for a predetermined time. Is displayed (S10). The ventilation stop time of the dressing room DR can be set to a time sufficient for the bather to use the normal dressing room DR after the humidifying and heating operation ends. At this time, the bather may arbitrarily change the ventilation stop time of the dressing room DR by a timer setting switch.

  When the predetermined time has elapsed (S11), the timer display is turned off (S12), and the stepping motor 23a is operated to increase the opening of the dressing room communication path Pd by the dressing room variable damper 23, thereby changing the dressing room DR. Is ventilated (S13). At this time, since the ventilation unit 3 is always operated for ventilation, the opening degree of each of the variable dampers 22, 23, 24 is returned to the opening degree for the normally ventilation operation (S14).

(Other embodiments)
(1) In the above embodiment, ventilation in the dressing room DR is stopped until a predetermined time has elapsed from the end of the humidifying and heating operation. However, a person sensing means such as a person sensing sensor is provided in the dressing room DR. When the sensing means does not sense any person in the dressing room DR, the opening degree of the communication path Pd for the dressing room is increased by the variable damper 23 for the dressing room as the second opening / closing means, and the person sensing means is placed in the dressing room DR. When sensing a person, the dressing room variable damper 23 may be controlled by the dressing room variable damper 23 so as to reduce the opening of the dressing room communication path Pd. According to this, since ventilation when the bather is using the dressing room DR can be suppressed depending on whether or not the human sensing means is sensed, a plurality of people perform mist bathing, and one of them during the humidifying heating operation. When the person of the part comes into the dressing room DR, the intake of cold air to the dressing room DR can be reduced without ending the humidifying and heating operation. In addition, the ventilation operation of the dressing room DR can be controlled without setting the timer, and the feeling of cold wind when the bather enters the dressing room DR before the humidification heating operation can be reduced. Further, the stop of the ventilation operation of the dressing room DR may be controlled by both the timer and the human sensing means.
(2) In the above embodiment, the bathroom variable damper 22 is in the bathroom inlet 14 of the ventilation unit 3, the dressing room variable damper 23 is in the dressing room inlet 15, and the toilet variable damper 24 is in the bathroom intake. Each opening 16 is not necessarily limited to the above-described configuration, and the opening / closing means may be provided in each communication path of the bathroom communication path Pb, the dressing room communication path Pd, and the toilet communication path Pt. Good. For example, the dressing room variable damper 23 may be provided in the pipe joint 20 or may be provided at a position adjacent to the suction port of the dressing room DR.
(3) In the above embodiment, a variable damper whose opening degree is adjustable is used as the opening / closing means, but a shutter mechanism that only opens and closes each communication path may be used instead of the variable damper.
