  The present invention relates to a humidification air conditioning system for performing humidification heating in a room such as a bathroom or a shower room.

  2. Description of the Related Art Conventionally, a mist device that blows hot and cold water into a bathroom and humidifies and heats the bathroom has been proposed (see, for example, Patent Document 1).

  Such a mist device has a configuration in which one or a plurality of mist nozzles are installed on a wall surface of a bathroom or the like, and hot water supplied from a water heater is used as a mist to be ejected into the bathroom.

  On the other hand, a mist device that ejects mist in combination with hot air blowing by a heater has been proposed (see, for example, Patent Document 2).

Japanese Examined Patent Publication No. 6-59301 JP 2002-61860 A

  In a mist device using a mist nozzle, a large amount of mist is ejected, so that the humidity in the room can be increased rapidly. However, the heat in the room is taken away with the evaporation of a large amount of mist, and the temperature in the room is lowered, so that it feels chilly.

  Moreover, when a bather bathes a body with a large amount of mist, the body gets wet, and there is a possibility that the bather cannot visually perceive the sweating effect.

  On the other hand, when the heating by the heater is used together, the temperature drop in the room can be suppressed. However, if the mist is continuously blown out, the mist is blown out after the room is in a predetermined high humidity state. However, evaporation hardly occurs, and wasteful consumption of hot water increases.

  Moreover, when the mist ejection is stopped, consumption of hot water is suppressed, but the humidity in the room is lowered and cannot be kept in a predetermined high humidity state.

  Furthermore, if a mist device provided with a mist nozzle that ejects finer mist is used, the amount of mist ejected is reduced, so that a temperature drop due to evaporation of mist can be suppressed. In addition, the body of the bather is difficult to get wet with the mist, and the bather can feel the sweating effect.

  However, since the amount of mist ejected is reduced, the evaporation of mist is not promoted, and it is not possible to obtain high humidity enough to reach a comfortable mist environment, or it takes time to achieve a predetermined high humidity state. There is a case.

  The present invention has been made to solve such a problem, and provides a humidification air conditioning system that performs humidification heating in a room in a short time and maintains the humidification heating room in a state where a sweating effect can be experienced. With the goal.

  In order to solve the above-described problems, a humidifying air-conditioning system according to the present invention blows, with an air-conditioning apparatus having a heating unit for heating a room, and fog generated by exciting water with an ultrasonic vibrator. And a humidifying device having mist ejecting means for ejecting mist.

  In the humidification air-conditioning system of the present invention, mist is ejected by the humidification device, and heating operation is executed by the air-conditioning device to perform humidification heating in the room. When the room is in a predetermined high humidity state with humidification heating, the humidifying device switches the operation of jetting mist to the operation of blowing out mist to keep the room in a high humidity state.

  According to the humidification air-conditioning system of the present invention, when humidifying and heating a room, the mist ejection in the humidifier and the heating operation in the air-conditioner can be linked, so that the room can be heated to a predetermined high humidity in a short time. Can be in a state.

  Further, when the room is in a predetermined high humidity state, the mist is blown out in place of the mist by the humidifier, so that consumption of hot water can be suppressed and the room can be maintained in a high humidity state.

  Furthermore, the mist blown out by the humidifying device is generated using an ultrasonic vibrator, so that it is made finer than the mist and has no granular feeling, and the perspiration effect can be realized.

  Further, the mist blown out by the humidifier is generated using an ultrasonic vibrator, so that the humidifier does not require an electric heater or the like, and can reduce power consumption.

  Hereinafter, embodiments of the humidification air conditioning system of the present invention will be described with reference to the drawings.

  Further, the main control unit 7A controls the heater 32, the fan motor 33a and the damper motor 35c of the bathroom air conditioner 3A according to a predetermined operation in the main operation unit 5A as a single operation of the bathroom air conditioner 3A. A ventilation operation mode, a drying operation mode, a cool air operation mode, or a 24-hour ventilation operation mode is selectively executed.

(1-6) Configuration Example of Sub-Operation Unit of Humidification Air-Conditioning System FIG. 6 is a configuration diagram illustrating an example of a sub-operation unit installed in a bathroom in the humidification air-conditioning system of the present embodiment.

  The sub operation unit 6A is an example of the operation unit, and is provided on the wall surface of the bathroom 101 shown in FIG. 1 and includes a mist button 60M that ejects the mist M in the humidification heating operation mode and an ultrasonic humidification button 60F that blows out the fog F. . The mist button 60M and the ultrasonic humidification button 60F are examples of operation switching operation means, and are an operation for switching between an operation in which the mist M is ejected by the mist nozzle 20M in the humidifier 2A and an operation in which the mist F is blown out by ultrasonic humidification by the humidifier 20F. Receive.

  The sub-operation unit 6A includes a display lamp 61 that notifies the bather of the selected operation mode corresponding to the mist button 60M and the ultrasonic humidification button 60F.

  Furthermore, the sub-operation unit 6A is provided with a stop button 62 for stopping the humidifying / heating operation mode or the like.

  By installing such a sub-operation unit 6A in the bathroom 101, the bather can switch the blowing of the mist M and the mist F during bathing.

<Operation example of humidification air conditioning system of this embodiment>
Next, with reference to each figure, the operation example of the humidification heating operation mode performed with the humidification air conditioning system 1A of this Embodiment is demonstrated.

  In order to humidify and heat the bathroom 101, the bather or the like operates the predetermined operation button 50 of the main operation unit 5A installed in the washroom 102 to select the humidification heating operation mode.

  When the humidifying / heating operation mode is selected, the main controller 7A drives the damper motor 35c of the bathroom air conditioner 3A to move the damper 35 to the circulation position shown in FIG. 3A, and drives the fan motor 33a. While rotating the fan 33, the heater 32 is energized.

  Thereby, in the bathroom air conditioner 3A, the air RA in the bathroom 101 is sucked from the suction grille 37a of the front panel 37, the hot air HA is blown from the blowout grille 37b, and the interior of the bathroom 101 is heated.

  When the main control unit 7A starts the heating operation in the bathroom air conditioner 3A and starts heating the bathroom 101, the temperature detection sensor 38a detects the temperature of the bathroom 101, and the temperature of the bathroom 101 is adapted to a predetermined mist ejection. Determine if room temperature is reached.

  When the temperature of the bathroom 101 detected by the temperature detection sensor 38a reaches a predetermined mist ejection compatible room temperature, the main control unit 7A continues the heating operation in the bathroom air conditioner 3A, and issues an instruction to eject the mist M. It transmits to control part 8A.

  When the sub-control unit 8A receives an instruction to eject the mist M from the main control unit 7A, the sub-control unit 8A opens the second water supply valve 22mb of the humidifier 2A. Thereby, the hot water HW is supplied from the hot water supply device 4 to the mist nozzle 20M, and the mist M is ejected from the mist nozzle 20M in the humidifying device 2A.

  As described above, in the humidifying and heating operation mode, first, the warm air HA is blown out by the bathroom air conditioner 3A to start heating the bathroom 101, and then the temperature of the bathroom 101 detected by the temperature detection sensor 38a is a predetermined mist ejection. The temperature of the bathroom 101 can be raised in a short time by performing the control to start the ejection of the mist M after the temperature reaches the suitable room temperature.

  Moreover, while blowing the mist M from the mist nozzle 20M with the humidifier 2A and blowing the warm air HA with the bathroom air conditioner 3A, the humidity of the bathroom 101 can be raised in a short time, and the mist M can be evaporated. The accompanying temperature reduction can be suppressed and the temperature of the bathroom 101 can be raised, and the bathroom 101 becomes a predetermined high-humidity mist state (relative humidity 100%) in a short time.

  When the main control unit 7A performs the humidification heating of the bathroom 101 in conjunction with the ejection of the mist M in the humidification apparatus 2A and the heating operation in the bathroom air conditioner 3A, the main control unit 7A detects the temperature of the bathroom 101 detected by the temperature detection sensor 38a. The humidification operation by the mist M is switched to the ultrasonic humidification operation by automatic switching according to the temperature or the like, or manual switching by the operation of the ultrasonic humidification button 60F of the sub-operation unit 6A by the bather.

  That is, when switching to the ultrasonic humidification operation in the humidification heating operation mode, the main control unit 7A transmits an instruction to stop the ejection of the mist M to the sub control unit 8A. When the sub control unit 8A receives an instruction to stop the ejection of the mist M from the main control unit 7A, the sub control unit 8A closes the second water supply valve 22mb of the humidifier 2A. Thereby, supply of hot water HW from hot water supply device 4 to mist nozzle 20M is stopped, and ejection of mist M from humidifying device 2A stops.

  Next, the main control unit 7A transmits an instruction to blow out the fog F with a predetermined output to the sub control unit 8A. When the sub control unit 8A receives an instruction to blow out the fog F from the main control unit 7A, the sub control unit 8A drives the ultrasonic vibrator 23 of the humidifying unit 20F and drives the fan motor 25a of the blower fan unit 21.

  Thereby, the fog F generated by vibrating the water W stored in the water tank 22 is blown to the air RA of the bathroom 101 which is sucked from the suction grille 27a and circulated when the fan 25 is driven to rotate. In the humidifier 2A, the mist F and the air humidified with the mist F are blown out from the blowout grill 27b.

  In addition, when switching from humidification operation by mist M to ultrasonic humidification operation automatically according to sensor output etc., it installs in the main operation part 5A installed in the washroom 102 shown in FIG. The bather or the like is notified that the preparation of the mist bath has been completed by sound output by a buzzer (not shown) provided in the sub-operation unit 6A, or by a notification means such as lighting of an LED or the like.

  As described above, when switching to the ultrasonic humidification operation in the humidification heating operation mode, the air humidified by the fog F and the fog F is blown out to the bathroom 101. The mist F by ultrasonic humidification is finer than the mist M by the mist nozzle 20M and does not have a granular feeling. Therefore, even if the bather is exposed to the mist F, it does not adhere as water droplets and can feel the sweating effect. .

  In addition, only ultrasonic humidification may take time to bring the interior of the bathroom 101 to a predetermined high humidity state, and may not be able to increase to the required humidity. Can raise humidity in a short time by spraying mist M and performing humidification.

  Further, if the mist M is continuously ejected in the humidifying and heating operation mode, after the inside of the bathroom 101 is in a predetermined high humidity state, even if the mist M is ejected, almost no evaporation occurs, so that the waste of hot water is lost. However, water consumption can be suppressed by switching to ultrasonic humidification.

  Here, when the ultrasonic humidification operation is started in the humidification heating operation mode, the humidity of the bathroom 101 is detected by a humidity detection sensor (not shown), and the output of the ultrasonic transducer 23 is adjusted so as to maintain a desired humidity. Thus, the humidification amount may be controlled.

  In the ultrasonic humidification operation, the ultrasonic vibrator 23 may be intermittently driven to control the humidification amount, or the driving of the ultrasonic vibrator 23 may be stopped.

  Furthermore, at the start of the humidifying and heating operation mode, the ultrasonic humidifying operation by the humidifying device 2A may be used in combination with the heating operation in the bathroom air conditioner 3A.

  That is, when a heating operation is performed with the bathroom air conditioner 3A, the humidity (relative humidity) decreases as the temperature in the bathroom 101 increases. Therefore, the mist F is blown out by the ultrasonic humidification operation by the humidifier 2A. Here, when the mist F is blown out by the humidifying device 2A, the heat in the bathroom 101 is taken away due to the evaporation of moisture, but since the amount of moisture is small, the temperature drop due to humidification is suppressed.

  Thereby, the temperature of bathroom 101 can be raised, suppressing both the temperature fall accompanying humidification, and the humidity fall accompanying the temperature rise by heating. In the humidifying device 2A, by generating the fog F using the ultrasonic vibrator 23, it is possible to suppress an increase in power consumption even in conjunction with the heating operation of the bathroom air conditioner 3A.

  Then, after the ultrasonic humidification operation by the humidification device 2A is linked to the heating operation in the bathroom air conditioner 3A, the operation is switched to the humidification operation by the mist M, so that the interior of the bathroom 101 is brought into a predetermined high humidity state in a shorter time. can do.

  In addition, after the humidifying operation by the mist M in the humidifying device 2A is linked to the heating operation in the bathroom air conditioner 3A, when the inside of the bathroom 101 becomes a predetermined high humidity state, the operation may be switched to the ultrasonic humidifying operation. The spraying of the mist M may be stopped without switching to the ultrasonic humidification operation, and the heating operation in the bathroom air conditioner 3A may be stopped.

  Further, when the bather operates the mist button 60M of the sub-operation unit 6A shown in FIG. 6 during the ultrasonic humidification operation, the main control unit 7A stops the blowing of the mist F and ejects the mist M. The instruction is transmitted to the sub control unit 8A.

  Thereby, in the humidifier 2A, the blowing of the mist F by ultrasonic humidification is stopped, and the mist M is ejected from the mist nozzle 20M.

  In this way, by allowing the sub-operation unit 6A installed in the bathroom 101 to switch between the ejection of the mist M and the ultrasonic humidification, the bather in the bathroom 101 selects the humidification method according to the preference. It is possible to meet the demands of bathers.

<Example of water supply / drainage operation of humidifier>
In the humidification air conditioning system 1A, the output of the water level sensor 22w is monitored so that the water tank 22 is not emptied. That is, during the ultrasonic humidification operation, the humidifier 2A determines whether or not the water level in the water tank 22 has decreased to a predetermined lower limit position from the output of the water level sensor 22w.

  If it is determined from the output of the water level sensor 22w that the water level in the water tank 22 has dropped to a predetermined lower limit position, the first water supply valve 22sb is opened. Thereby, clean water SW is supplied to the water tank 22 from the water supply port 22sw.

  When the humidifier 2A determines from the output of the water level sensor 22w whether or not the water level in the water tank 22 has risen to a predetermined upper limit position, and determines that the water level has risen to a predetermined upper limit position, the first water supply valve Close 22sb.

  By the water supply control described above, it is possible to prevent the water W from being replenished by generating the fog F by the ultrasonic vibrator 23 and the water tank 22 from becoming empty.

  In addition, when it is necessary to drain the water in the water tank 22 due to maintenance during operation stop, the drain valve 22eb is opened, and the water in the water tank 22 is drained from the drain port 22ew.

  The present invention is applied to an air conditioning system that performs humidification heating such as in a bathroom or a shower room.
