Description

  The present invention relates to a bathroom heating and drying system in which a plurality of bathroom heating and drying machines are installed in a bathroom.

  Conventionally, it has been installed in the unit bath to temporarily set the mist spray temperature to a high temperature state, and when the bathroom temperature reaches the set temperature, it has a hot dash function, which is short even in winter. A mist sauna apparatus that enables a mist sauna bath over time is known (for example, see Patent Document 1).

  However, unit baths that are generally sold are 1 to 1.5 tsubo types, and this wide unit bath is a mist sauna in a relatively short time using the technique disclosed in Patent Document 1. Although bathing is possible, in some luxury apartments, etc., the bathroom space becomes even larger, and the driving ability of one mist sauna device is insufficient. Therefore, in order to enjoy a mist sauna bath comfortably in such a large bathroom space, it will be necessary to install multiple mist sauna devices, but by simply installing multiple mist sauna devices in the bathroom, There is a problem that a plurality of remote controllers to be operated are required and the operation becomes troublesome. In particular, in the case of a wired remote controller, there is also a problem that it takes time for wiring construction.

Therefore, as another conventional example, at least one remote controller and at least one of a plurality of air conditioners are provided with a receiving unit, the plurality of air conditioners are connected via a common bus, and the air conditioner provided with the receiving unit is a remote controller. There is known an air conditioner that changes the operating state of an air conditioner in response to this command and that can transmit a command of a remote controller to all the air conditioners via a common bus. (For example, see Patent Document 2)
However, because it is a bathroom space, the mist sauna device is installed adjacent to the ceiling of the unit bath. In such a case, in the prior art of Patent Document 2, the operation can be turned on and off with one remote controller, but a plurality of devices do not operate in cooperation. For example, in the case of mist sauna operation, using a temperature sensor to prevent spraying cold water, spraying after detecting a temperature above a certain level of hot water supplied from a heat source, etc., after an operation start command is issued from the remote control A temperature factor is involved in the spray start condition until the actual spray start. There is variation in the temperature detection by the sensor, and spraying is started in one mist sauna device, but the other mist sauna device does not spray, so the discomfort due to the adjacent installation is conspicuous There's a problem.
JP 2007-61413 A JP-A-3-113225

  The present invention has been invented in view of the above-described conventional problems, and allows a plurality of bathroom heaters and dryers to be operated synchronously, can prevent a sense of incongruity due to variations in each operation, and each bathroom heater and dryer.

It is preferable that the load device of the mist generator 2 in the device 3A and the load device of the mist generator 2 in the second mist sauna device 3B corresponding thereto are operated in synchronization. In this case, the two mist sauna devices 3A and 3B can be operated synchronously, and a comfortable mist sauna can be enjoyed in a large bathroom space while preventing a sense of incongruity in the driving situation.

  In addition, the control unit 4 is configured to determine the state of the environmental load of the bathroom 10 and the single operation of one of the first device and the second device, or both simultaneously according to the state of the environmental load. It is preferable to include an operation number determination unit 41 that determines any one of the operations. In this case, it is possible to perform the operation with an appropriate capacity according to the state of the environmental load of the bathroom 10.

  In addition, when performing the above-described single operation, the control unit 4 preferably selects a device that performs the single operation based on the past operation history of the first and second devices. As a result, the service life of the entire system can be improved.

  Further, the control unit 4 recognizes the bathroom heating / drying machine 1 to which the specific remote controller 19a is connected and the other bathroom heating / drying machine 1 is communicably connected to the bidirectional communication means 6 as the first device, It has an automatic recognition function for recognizing a bathroom heater / dryer 1 to which the specific remote controller 19a is not connected and the other bathroom heater / dryer 1 is communicably connected to the bidirectional communication means 6 as the second device. In this case, it is not necessary to perform switching setting by a switch on the operating device side of the specific remote controller 19a.

  The bathroom heating / drying system according to the present invention includes a synchronized operation control mode for synchronizing the operation of the load device of the second device with the operation of the load device of the first device, thereby providing a plurality of bathroom heating units. The dryer can be operated synchronously, and it is possible to prevent a sense of incongruity due to variations in each operation even in a large bathroom space, and it is not necessary to finely adjust the control program for each bathroom heating / dryer. By simply operating the first device designated by the designation means by remote control, the respective devices can be operated synchronously, and the operation can be simplified.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 1, the bathroom heating / drying system of the present invention is configured by connecting a plurality of (two in this example) mist sauna devices 3 (3 </ b> A, 3 </ b> B) via bidirectional communication means 6. Yes.

  The mist sauna apparatus 3 of this example is installed in the ceiling part of a bathroom. A heat source device (not shown) with a hot water supply function is installed outside the bathroom 10, a bathroom remote control 19a is installed on the wall inside the bathroom 10, and a dressing room remote control (not shown) is installed on the wall of the dressing room. is set up.

  The bathroom remote control 19a includes, for example, display sections for operation mode, temperature, air volume, wind direction, and bathing time, a mist sauna switch for instructing start of mist sauna operation, a mist strength switch for switching mist strength, and a target set temperature. A temperature setting switch for setting (for example, 38 ° C. to 46 ° C.), a heating switch, a cool air switch, a wind direction switch, a stop switch, a start / stop switch for counting the bathing time, a reset switch, and the like are provided. A similar operation unit is provided in the dressing room remote control. Thus, the operation before bathing can be performed with the dressing room remote controller, and the operation during bathing can be adjusted with the bathroom remote controller 19a.

  In this example, in addition to the original function of operating the first mist sauna device 3A, the bathroom remote controller 19a uses the mist sauna device to which the bathroom remote controller 19a is connected as described below as the first mist sauna device. It also has a function of designating as the device 3A.

  The two mist sauna apparatuses 3 of this example have the same structure, and only one of them is shown in FIG. As shown in FIG. 4, each mist sauna device 3 includes a bathroom heating dryer 1 that supplies hot air N into the bathroom 10, a mist generator 2 that sprays hot water as mist M, and a bathroom heating dryer 1. And a control unit 4 (FIG. 3) for controlling the mist generator 2. In the example of FIG. 4, it is separated into a heating dryer body box 1a for storing the bathroom heating dryer 1 and a mist unit box 2a, and they are coupled to each other with the mist unit box 2a mounted on the heating dryer body box 1a. Has been.

  In the heating dryer box 1a, there are a circulation fan 22, an air conditioner heat exchanger 33 that heats the air that is ventilated by the circulation fan 22 to the circulation ventilation path 5, and a bathroom thermistor 16 that detects the bathroom temperature. Has been placed. The circulation fan 22 and the heat exchanger 33 for air conditioning constitute a heating function for sucking the air in the bathroom 10 and making it warm air and eject it into the bathroom 10. In this example, in order to increase the heat exchange efficiency of the heat exchanger 33 for air conditioning, the vertical heat exchange section 33a and the horizontal heat exchange section 33b are divided and arranged adjacent to each other, and the forward path 7a of the hot water circulation path 7 is provided. The heat exchange units 33 a and 33 b are connected to the entrance sides of the two heat exchange units 33 a and 33 b, respectively, and the heat exchange units 33 a and 33 b are connected to the return sides 7 b of the two hot water circulation paths 7. The forward path 7a of the hot water circulation path 7 is connected to the hot water supply side joint 20 on the hot water discharge side of the heat source machine, and the return path 7b of the hot water circulation path 7 is connected to the hot water return side joint 21 on the recovery side of the heat source machine. Yes.

  Here, in the forward path 7 a of the hot water circulation path 7, a thermal valve 8 that opens and closes the hot water circulation path 7 and a hot water thermistor 9 that detects the hot water temperature are arranged. The hot water temperature detected by the hot water thermistor 9 is the temperature of the hot water that heats the heat exchanger 33 for air conditioning and the liquid heat exchanger 11 described later, and the ON operation of the circulation fan 22 is performed as described later according to this temperature. Then, the opening / closing operation of the nozzle opening / closing valve 15 is performed. Here, the circulation fan 22 is constituted by, for example, a cross flow fan that rotates around a horizontal axis and performs both suction and exhaust of air along a direction orthogonal to the rotation axis, and is substantially in the direction of the rotation axis. A function of sucking air in the bathroom 10 through the air-conditioning heat exchanger 33 over a wide range over the entire width and ventilating the air heated by the air-conditioning heat exchanger 33 so as to blow out from the hot air outlet 32 to the bathroom 10. Have. Note that the ventilation fan 31 rotates, for example, around the vertical axis, sucks air from the lower side of the fan case, and exhausts ducts (not shown) from a discharge port opened on the side surface of the heater / dryer body box 1a. It is comprised so that air may be ventilated toward.

  On the other hand, the mist generator 2 heats the water supplied from the water supply solenoid valve 17 that opens and closes the water supply passage 12 connected to the water pipe via the water supply joint 26 and the water supplied from the water supply passage 12 with hot water from the heat source device. Liquid heat exchanger 11, a plurality of (for example, two) mist nozzles 13 (13 a, 13 b) for spraying water heated by the liquid heat exchanger 11 in a mist form, and each mist nozzle 13 individually And a pair of nozzle on-off valves 15 that are controlled to open and close, and a mist temperature thermistor 30 that detects the mist spray temperature. In the example of FIG. 4, the liquid heat exchanger 11 is disposed in the mist unit box 2a, and the mist nozzle 13 and the nozzle opening / closing valve 15 are disposed in the heating dryer body box 1a. The mist ejection amount of the mist nozzles 13a and 13b is, for example, 0.5 liter / min, and is designed to eject both in strong operation and in one operation in weak operation.

  Here, the liquid heat exchanger 11 is composed of, for example, a plate heat exchanger in which a plurality of corrugated plate-like heat transfer plates are stacked at intervals. The primary side water channel of the liquid heat exchanger 11 communicates with the water supply channel 12, and the secondary side water channel communicates with the hot water branch circuit 23. An upstream of the hot water branch circuit 23 is connected to the forward path 7a of the hot water circuit 7 on the near side of the thermal valve 8 via a water proportional valve 14 that can change and adjust the supply amount of hot water. The other end of the branch circulation path 23 is connected to the return path 7 b of the hot water circulation path 7.

  In addition, one end of a drainage channel 24 is connected between the liquid heat exchanger 11 in the water supply channel 12 and the nozzle opening / closing valve 15. The other end of the drainage channel 24 is connected to a drainage joint 27 and a drainage pipe (not shown) via a drainage electromagnetic valve 18. For example, the drainage channel 24 is opened with the nozzle opening / closing valve 15 closed before the mist sauna operation is started, and is accumulated in the liquid heat exchanger 11 and the water supply channel 12 through the drainage channel 24. It will be possible to drain the water that is outside. The drainage channel 24 communicates with the air inflow channel 29 via a vacuum breaker (not shown) provided in the drainage solenoid valve 18, and the drainage solenoid valve is made to be in an atmospheric pressure state during drainage. Dirty water drained from 18 prevents backflow into the drainage channel 24.

  The sensor detection signals from the bathroom thermistor 16, the hot water thermistor 9, and the mist temperature thermistor 30 are sent to the control unit 4 (FIG. 3) incorporating a microcomputer. The control unit 4 individually controls the load devices of the bathroom heating dryer 1 and the mist generator 2 based on the operation start command from the bathroom remote controller 19a and the sensor detection data, and operates the mist sauna and cool air. This is for performing various operations such as operation and heating operation, and a control program common to the two mist sauna devices 3A and 3B is incorporated.

  In addition, the load equipment here refers to all the equipment (circulation fan 22, water supply electromagnetic valve 17, nozzle on-off valve 15, etc.) which operate for heating drying and mist spraying.

  Here, in the present invention, as shown in FIG. 1, the person connected to the bathroom remote controller 19a constituting the first device designating means 19 is the first mist sauna apparatus 3A, and the person not connected to the bathroom remote controller 19a is used. Let it be the 2nd mist sauna apparatus 3B. That is, the basic structure of the first mist sauna device 3A and the second mist sauna device 3B is the same, but the one connected to the bathroom remote controller 19a becomes the first mist sauna device 3A, and the bathroom remote controller 19a is not connected. This is the second mist sauna device 3B. And each control part 4 of 1st and 2nd mist sauna apparatus 3A, 3B communicates via the bidirectional | two-way communication means 6. FIG. In the example of FIG. 1, the bidirectional communication means 6 uses a signal line 6a that connects the first mist sauna device 3A and the second mist sauna device 3B. As shown in FIG. 2, an infrared method or a wireless method may be used in which an infrared signal 6b is connected using a communication unit (light emitting unit and light receiving unit) 35 and an infrared communication unit (light emitting unit and light receiving unit) 36. .

  Furthermore, the control unit 4 has a synchronous operation control mode. This is because when the first mist sauna device 3A receives an operation start command from the bathroom remote controller 19a, the sensor detection data of the second mist sauna device 3B is transmitted to the first mist sauna device 3A, and the first The mist sauna device 3A determines the operating state of the load device based on the sensor detection data detected by the first mist sauna device 3A itself and the sensor detection data sent from the second mist sauna device 3B, and based on this determination The first mist sauna device 3A operates a predetermined load device at the same time, and simultaneously transmits a load operation command signal to the second mist sauna device 3B to correspond to the load device in which the first mist sauna device 3A operates. The load device of the second mist sauna device 3B to be operated is operated synchronously.

  Next, the operation of the bathroom heating / drying system having the above-described configuration will be described by taking as an example the case of performing a mist sauna operation. FIG. 5 shows a control flow of the first mist sauna device 3A, and FIG. 6 shows a control flow of the second mist sauna device 3B.

  When the mist sauna switch of the bathroom remote control 19a is turned on (step S1 in FIG. 5), the first mist sauna device 3A receives a mist sauna operation start instruction from the bathroom remote control 19a. At this time, the first mist sauna device 3A turns on its own thermal valve 8 and transmits a signal for turning on the thermal valve 8 of the second mist sauna device 3B to the second mist sauna device 3B. . When the second mist sauna device 3B receives the transmission from the first mist sauna device 3A, the sensor detection data of the second mist sauna device 3B itself (for example, detection data of the hot water thermistor 9) is used as the first mist sauna device 3B. 3A (steps S11 → S10 in FIG. 6). The first mist sauna device 3A uses both the detected temperature of its own hot water thermistor and the detected temperature of the hot water thermistor of the second mist sauna device 3B transmitted from the second mist sauna device 3B. , 3B is detected that hot water is supplied. The first mist sauna device 3A, which has detected that hot water has been supplied to both devices 3A, 3B, turns on its own nozzle opening / closing valve 15 to start the mist sauna operation (step S2 in FIG. 5). A signal is transmitted to the second mist sauna device 3B, and the second mist sauna device 3B turns on the nozzle opening / closing valve 15 in response to the signal to start the mist sauna operation (step S12 in FIG. 6). Even during operation, the second mist sauna device 3B receives the first sensor detection data of the second mist sauna device 3B itself (for example, detection data of a hot water thermistor) if there is an instruction from the first mist sauna device 3A. To the mist sauna apparatus 3A (steps S14 → S13 in FIG. 6). In this way, both devices 3A and 3B can start and continue mist spraying at substantially the same timing. In this way, even in a large bathroom space, the body is sufficiently warmed to promote a large amount of perspiration, relieve fatigue and stress, obtain a refreshing feeling, and further promote blood flow, increase metabolism, and in some cases lose weight. In addition, it is possible to obtain a useful effect, and in winter, it is possible to perform hot dash operation in which the mist spray temperature is temporarily raised to a high temperature, and when the bathroom temperature reaches the set temperature, the normal spray temperature is restored. In the winter, you can enjoy a mist sauna bath in a short time. Note that the control of the load device not described in the flowcharts of FIGS. 5 and 6 is the same as that in Japanese Patent Application Laid-Open No. 2007-61413, and details thereof are omitted.

  Thereafter, when the mist sauna switch of the bathroom remote controller 19a is turned off (step S3 in FIG. 5), the first mist sauna device 3A stops the operation of its own load device to end the mist sauna operation, and the second An instruction to stop the operation is sent to the mist sauna device 3B (step S4 in FIG. 5), and the second mist sauna device 3B stops the operation of the load device and ends the mist sauna operation (steps S14 → S15 in FIG. 6). .

  Thus, in the case where one mist sauna device 3A or 3B has insufficient driving capability in a large bathroom space as described above, the two mist sauna devices 3A and 3B are operated simultaneously. At this time, the first mist sauna device 3A operates its own load device based on the sensor detection data held by itself and the sensor detection data sent by the second mist sauna device 3B. An instruction to operate the same load device is issued to the mist sauna device 3B, and the second mist sauna device 3B receiving the instruction can operate the instructed load device as instructed. Therefore, each of the two devices can be operated synchronously by operating only one bathroom remote controller 19a. That is, since the two devices operate in cooperation, it is possible to enjoy the mist sauna bath comfortably even in a large bathroom space. In addition to the mist sauna operation, the load device can be operated synchronously by the synchronous operation control mode also in the bathroom heating operation, the ventilation operation, etc., so that the operation is performed between the devices 3A and 3B in any operation. It is possible to eliminate a sense of incongruity due to variations in Further, it is not necessary to finely adjust the control program for each of the devices 3A and 3B, and in addition, the first mist sauna device 3A and the other second mist sauna device 3B are connected via the bidirectional communication means 6. As a result of the connection, the devices 3A and 3B can be operated synchronously only by operating the first mist sauna device 3A with the bathroom remote controller 19a, and the operation becomes extremely simple. In addition, the bathroom remote controller 19a is a wired remote controller. Even if it exists, there exists an advantage which can aim at labor saving of wiring construction.

  Further, in this example, the first mist sauna device 3A is based on the detected temperature of its own hot water thermistor and the detected temperature of the hot water thermistor of the second mist sauna device 3B transmitted from the second mist sauna device 3B. In this case, it is detected that hot water is supplied to both devices 3A, 3B. At this time, an average value of sensor detection temperatures of both devices 3A, 3B is obtained, and both devices 3A are determined based on this. , 3B is detected to be supplied with warm water. Thus, it is possible to improve the sensor detection accuracy by obtaining the average value of the detection data.

  In addition, on the control board (not shown) of the mist sauna device 3 of this example, two connectors (for the dressing room remote control and for the bathroom remote control) are provided so that two remote controls can be connected to communicate. In this case, one communication connector may be added for communication between the mist sauna devices 3A and 3B, and communication between the mist sauna devices 3A and 3B may be performed. In this way, one communication circuit is added, resulting in an increase in cost. Therefore, a structure that does not require the addition of a dedicated connector for communication is desirable. As an example, the bathroom remote controller 19a (specific remote controller) is connected to one connector of the first mist sauna apparatus 3A, and the dressing room remote controller is connected to one connector of the second mist sauna apparatus 3B. Communication between the mist sauna devices 3A and 3B is performed using the other connector. In this case, communication is performed by automatically recognizing the person connected to the bathroom remote controller 19a (specific remote controller) as the first mist sauna apparatus 3A and the person connected to the dressing room remote controller as the second mist sauna apparatus 3B. It can be easily realized by adding software only, without adding a circuit.

  FIG. 7 shows another example of the control unit 4. The basic configuration other than the control unit 4 is the same as in the above embodiment. The control unit 4 of this example includes a determination unit 40 that determines the state of the environmental load of the bathroom 10, and one of the first mist sauna device 3A and the second mist sauna device 3B according to the state of the environmental load. An operation number determination unit 41 that determines either operation (single-unit operation) or simultaneous operation of both (two-unit operation) is provided. Therefore, the size and required capacity of the bathroom space are determined from the room temperature of the bathroom 10 at the start of operation, the rate of increase in the room temperature from the start of operation, and the temperature difference between the room temperature and the target temperature, and it is determined that one operation is sufficient. In this case, only one of them is operated independently based on the determination. At this time, the durability may be improved by alternately operating the first mist sauna device 3A and the second mist sauna device 3B, and driving with an appropriate capacity according to the state of environmental load. Is possible.

  When one of the first mist sauna device 3A and the second mist sauna device 3B is operated alone, the past operation history of the first and second mist sauna devices 3A, 3B is stored in the control unit 4. It is also possible to provide an operation history storage unit 42 and select a device that operates independently based on the past operation history (for example, the total operation time) of each of the first and second mist sauna devices 3B. is there. Therefore, when performing the independent operation, the total operation time of each device stored in the operation history storage unit 42 is compared, and the device having the shorter operation time is selected to perform the independent operation. The service life of the bathroom heating and drying system as a whole can be improved by leveling the operation of the mist sauna apparatuses 3A and 3B.

  In addition, the control unit 4 uses the mist sauna device 3 to which the bathroom remote controller 19a (specific remote controller) is connected and the other mist sauna device 3 is communicably connected to the bidirectional communication means 6 as the first mist sauna device. Automatic recognition function for recognizing a mist sauna device 3 as a second mist sauna device 3B, which is recognized as 3A and the bathroom remote controller 19a is not connected and the other mist sauna device 3 is connected to the bidirectional communication means 6 so as to be communicable It is desirable to provide the part 43 (FIG. 7). FIG. 8 shows an example of this, and when it is not connected to another mist sauna apparatus in step S20 of FIG. 8, the process proceeds to step S21 to execute the single operation control mode (one mist sauna). It is recognized as a system including only the device 3). If another mist sauna device is connected in step S20, the process proceeds to step S22. When it is recognized in step S22 that the bathroom remote controller 19a is connected, the process proceeds to step S23 and the first mist sauna device 3A is controlled. When it is recognized in step S22 that the bathroom remote controller 19a is not connected, the process proceeds to step S24 to perform control as the second mist sauna device 3B. Thus, the first mist sauna device 3A and the second mist sauna device 3B can be recognized depending on whether or not the bathroom remote controller 19a is connected. That is, the control program incorporated in each control unit 4 of each device 3A, 3B can automatically switch between master and slave only by the presence / absence of remote control connection. There is no need to perform switching settings, and as a result, the cost of the communication unit can be reduced and the construction can be simplified.

  As a modification of FIG. 8, a device to which the bathroom remote controller 19a (specific remote controller) is connected is recognized as the second mist sauna device 3B, and only the other devices are connected for communication without being connected to the bathroom remote controller 19a. It is also possible to incorporate a control program that recognizes the device as the first mist sauna device 3A. Moreover, although the specific remote control is the bathroom remote control 19a, the dressing room remote control may be a specific remote control.

  Further, in order to reduce the burden on the control unit 4, when the control operation is concentrated on one control unit 4 of the two mist sauna devices 3A and 3B, the operation is distributed to the other control unit 4. It is also possible to incorporate a control program for this purpose, and in this case, it is possible to reduce the burden on the control unit 4 due to the control operation being biased to one side.

  In the above-described embodiment, the case where the bathroom remote controller 19a also serves as the first device specifying means 19 has been described. However, the bathroom remote controller 19a and the first device specifying means 19 may be configured separately, for example, Software that designates one device to which the bathroom remote controller 19a is connected as the first device may be incorporated in the control unit 4.

  The bathroom heating / drying system according to the present invention is not limited to the mist sauna device 3 and can be similarly applied when only a bathroom heating / drying machine having no mist spraying function is installed.
