By the way, in the said conventional bathroom heating apparatus, since mist sprays in the bathroom in which water vapor | steam (or humidity) is not saturated, when the mist evaporates, it takes heat of vaporization from the air in a bathroom, Therefore It was a hindrance to the temperature rise in the bathroom.
For example, if only mist spraying is performed without pre-heating for mist sauna bathing, and mist spraying is started when bathing in the mist sauna, the heat in the bathroom is deprived of the heat of vaporization and the temperature in the bathroom decreases. End up. Also, if the mist spraying is interrupted while bathing in the mist sauna and the heating operation is continued, the humidity in the bathroom decreases, and when the mist spraying is resumed, the heat of vaporization is taken away from the air in the bathroom at this time. The temperature in the bathroom drops.
Patent Document 3 includes a heating means for creating a steam generation state for mist spraying and a dry warm air generation state for which mist spraying is not performed. When the humidity in the inside becomes the reference value (humidity 90%) or more, it is switched to a dry hot air generation state, and then, when the humidity in the bathroom becomes less than the above-mentioned reference value, it is switched again to the steam generation state. It is disclosed that a bather can take a bath in a comfortable heating state by maintaining the humidity of the water in a predetermined range (paragraph 0038 of Patent Document 3). However, even in this case, when the steam is generated, that is, when the mist is sprayed, the humidity in the bathroom is not saturated, so the vaporization of the mist still takes the heat of vaporization from the air in the bathroom and the temperature in the bathroom rises. Was hindering.
The present invention has been made in view of the above circumstances, and a mist sauna function that prevents the heat in the bathroom from being taken away by the heat of vaporization of water during the mist spraying, thereby preventing a temperature drop in the bathroom. It is an object to realize an attached bathroom heating device.

A humidifying means for sending humid air into the bathroom and a humidity detecting means for detecting the humidity in the bathroom are provided,
When the humidity detecting means detects a high humidity state in the bathroom by the humidifying operation of the humidifying means, the mist spraying from the mist blowing section is made possible.
Thereby, the humid air can be sent into the bathroom by the humidifying operation of the humidifying means to humidify the bathroom to a high humidity state. And when the high humidity state in the bathroom is detected by the humidity detecting means, the mist spraying from the mist blowing part is enabled, so that the mist is almost vaporized even if the mist is sprayed in the high humidity bathroom. There is no loss of heat of vaporization that causes the temperature in the bathroom to drop from the air in the bathroom. The high humidity state includes a humidity saturation state.

(2) In the bathroom heater with mist sauna function,
During preheating operation for a certain period of time before bathing in the mist sauna, only the heating operation is performed without the humidification operation of the humidification means in the previous period, and the humidification operation of the humidification means is performed with the heating operation in the latter period. May be.
That is, even if the humidifying operation by the humidifying means is not performed throughout the preliminary heating operation, by performing the humidification operation in the latter period, the interior of the bathroom can be brought into a high humidity state at the end of the preliminary heating. Therefore, it is possible to prevent waste of energy for making water or humid air used for humidification in the bathroom, and to reduce the running cost of preheating.
The latter stage of the preliminary heating operation includes, for example, a case where the remaining setting time of the preliminary heating operation is 5 minutes or less, or a case where the bathroom temperature reaches the set temperature due to the heating operation.

(3) In the above-mentioned bathroom heating device with mist sauna function,
You may make it stop the humidification driving | operation of the said humidification means at least during the mist spraying from the said mist blowing part.
That is, during the mist spraying, even if the humidifying operation of the humidifying means is stopped, the high humidity state in the bathroom can be maintained by the mist spraying. Therefore, by stopping the humidifying operation of the humidifying means during mist spraying, it is possible to prevent the waste of energy for making water and humid air used for humidification in the bathroom, and to reduce the running cost of mist sauna operation. Can do.

(4) Moreover, the said humidification means is good also as what sends warm water or water into a bathroom | heater with respect to the heat exchanger for heating mounted in this bathroom heater.
That is, by creating warm air by applying warm water or water to the heat exchanger, it is possible to take heat of vaporization from the heat exchanger as the hot water or the like evaporates. Therefore, the heat exchange efficiency of the heat exchanger should be improved by making the best use of the heat dissipation capacity of the heat exchanger and increasing the amount of heat exchange that was limited in heat exchange between the heat exchanger and air. Can do.

(5) In the bathroom heater with mist sauna function,
When a high humidity state in the bathroom is detected, it may be notified that mist spraying is possible.
Accordingly, the bather can easily know that the mist sauna bath can be immediately performed by mist spraying, and the usability is improved.

  As described above, according to the bathroom heating device with a mist sauna function according to the present invention, the mist spraying is performed from the mist outlet after the interior of the bathroom is brought into a high humidity state by the humidifying means. The mist hardly vaporizes and does not take away the heat of vaporization that causes the temperature in the bathroom to drop from the air in the bathroom. Therefore, it is possible to prevent a temperature drop in the bathroom during mist spraying when taking a mist sauna.

The humidifying spray section 2 is disposed above the heat exchanger 1 and connected to the pipe 13 from the mist unit 20 to receive supply of hot water. The hot water is applied to the heat exchanger 1 to generate wet air. Ensure that humid air is sent into the bathroom. The remaining hot water applied to the heat exchanger 1 by the humidifying spray section 2 is recovered by a recovery tray 4 installed below the heat exchanger 1. The blower fan 3 circulates the air in the bathroom through the bathroom heating unit 10 and blows warm air into the bathroom through the heat exchanger 1. The humidity sensor 5 is connected to the control board 6 and detects its humidity in the bathroom by exposing its sensing part in the bathroom. The sensing unit of the humidity sensor 5 may be provided in the bathroom heating unit 10 as long as the humidity in the bathroom can be detected. The control board 6 exchanges detection signals and control signals of the humidity sensor 5 and controls the operation of the bathroom heating unit 10. When the humidity sensor 5 detects humidity saturation in the bathroom by the humidifying operation by the humidifying spray unit 2, the control substrate 6 performs control so as to enable mist spraying from the mist nozzle 18. .

  The mist unit 20 includes a liquid-to-liquid heat exchanger 11 that performs heat exchange between liquid and liquid. The liquid heat exchanger 11 is connected to circulation pipes 23 and 24 from the heat source unit 30 and is circulated and supplied with a heat medium (hot water). Further, a water supply pipe 12 for supplying tap water, a pipe 14 to the mist nozzle 18, and a pipe 13 to the humidifying spray section 2 are connected to the liquid heat exchanger 11. The water supplied from is heated to a predetermined temperature to be warm water, and this hot water is supplied to the humidifying spray section 2 and the mist nozzle 18. The circulation pipe (outward pipe) 23 is provided with a flow rate control valve 17 for controlling the flow of the heat medium, and the pipes 13 and 14 are control valves such as electromagnetic valves for controlling the flow of hot water. 15 and 16 are provided. The flow rate control valve 17 controls the flow rate of the heat medium in the pipe 23 (including shut-off / circulation), but a valve that controls the flow of the heat medium ON / OFF may be used. Similarly, the control valves 15 and 16 also control the flow rate of hot water in the pipes 13 and 14 (including shut-off and flow). However, a valve for ON / OFF control of the flow of hot water may be used. .

The mist nozzle 18 is installed at a predetermined position such as a wall surface in the bathroom, and sprays the hot water supplied from the mist unit 20 into the mist in the bathroom. The mist nozzle 18 may be attached to an appropriate position such as a lower part or a front part of the bathroom heating unit 10.

The control board 25 is connected to the control board 6 of the bathroom heating unit 10 via a signal line 26, and also communicates with a bathroom remote controller 27 arranged in a dressing room and a kitchen remote controller 28 arranged in the kitchen. It is connected.

Next, the driving | operation operation | movement regarding the bathroom heating apparatus with a mist sauna function of this Embodiment 1 is demonstrated.
<Mist preheating operation>
First, the mist preheating operation for a certain time before bathing in the mist sauna will be described.
FIG. 2 shows an operation flow of the mist preheating operation. Referring to FIG. 2, when the bathroom remote controller 27 or the kitchen remote controller 28 is operated to start the mist preheating operation (S1), the command is transmitted from the remote controllers 27, 28 to the heat source unit 30 (S2), and then the heat source A mist preheating operation start command is transmitted from the machine 30 to the bathroom heating unit 10 through the control boards 25 and 6 (S3).

  Then, the heat source unit 30 is operated, and the mist preheating operation is started in the bathroom heating unit 10 (S4). When the start of the mist preheating operation is instructed by the operation of the remote controllers 27 and 28, the preheating operation time (for example, about 30 minutes) is appropriately set. When this mist preliminary heating operation is executed, the heat source 30 circulates the heat medium to the heat exchanger 1 of the bathroom heating unit 10 and heats the bathroom by blowing hot air from the blower fan 3. The hot water is not sprayed from the humidifying spray section 2 to the heat exchanger 1 by closing the control valve 15. That is, in the first half of the mist preheating operation, the humidifying operation by the humidifying spray unit 2 is not performed, and only the heating operation by dry warm air is performed.

  Next, it is determined whether or not the set time of the mist preheating operation has become, for example, the remaining 5 minutes or less (S5). If the set time has not become the remaining 5 minutes or less, whether or not the bath room temperature has reached the set temperature. (S6). When the set time for the mist preheating operation is less than 5 minutes or when the bath room temperature reaches the set temperature, the humidification operation is started (S7). That is, when this humidification operation is started, the heat medium from the heat source device 30 is circulated also to the liquid heat exchanger 11 of the mist unit 20, and the water supplied from the water supply pipe 12 is warmed. At this time, the control valve 15 is opened, and the hot water heated by the liquid heat exchanger 11 is sprayed from the humidifying spray section 2 to the heat exchanger 1 of the bathroom heating unit 10 through the pipe 13. Since the sprayed hot water warms up the air and humidifies it at the same time, the humidified and humid air is blown out from the blower fan 3 to humidify and heat the interior of the bathroom. The remaining hot water sprayed on the heat exchanger 1 is collected in the collection tray 4.

  And when such humidification operation is continued and the humidity in the bathroom rises and the humidity sensor 6 detects the humidity saturation state in the bathroom (S8), mist spraying from the mist nozzle 18 is enabled. . When the mist preheating time is up, information on completion of mist bath preparation is transmitted to the heat source unit 30 (S9), and information on completion of mist bath preparation is transmitted from the heat source unit 30 to the bathroom remote controller 27 and the kitchen remote controller 28 (S15). ) In the remote controllers 27 and 28, the completion of preparation for mist bathing is notified by voice guidance or melody, and "Mist preparation completion" or the like is displayed on the liquid crystal screen or the like (S16). Similarly, the bathroom heating unit 10 also notifies completion of mist bathing preparation by voice guidance or melody (S10). When the mist switch is turned on with the bathroom remote control 27 or the like (S11), a mist timer is set, and a mist spray notice is notified by voice guidance or melody (S12), and mist spraying is started from the mist nozzle 18. (S13). Thereafter, when the mist switch is turned off or the mist timer expires, mist spraying from the mist nozzle 18 is stopped (S14).

  As described above, in the mist preheating operation, the humidity in the bathroom is increased by the humidification operation in the later stage of the mist preheating operation such as when the set time is less than 5 minutes or when the bath room temperature reaches the set temperature. Can be easily humidified to saturation. That is, when warm water is sprayed on the heat exchanger 1 of the bathroom heating unit 10, the temperature near the heat exchanger 1 is higher than the atmosphere in the bathroom, and therefore, the saturated water vapor pressure is high and it is easy to vaporize. When this humid air is fed into the bathroom, the temperature in the bathroom is relatively low and the saturated water vapor pressure is low, so that it becomes supersaturated and the humidity in the bathroom can be easily saturated.

When the humidity sensor 5 detects the humidity saturation state in the bathroom, the mist spraying from the mist nozzle 18 is possible, so that the mist can be vaporized even if the mist is sprayed in the humidity saturated bathroom. It does not take heat of vaporization from the air in the bathroom. Therefore, it is possible to prevent a temperature drop in the bathroom when the mist is sprayed from the mist nozzle 18 when taking a mist sauna after the mist preheating.
Moreover, since the inside of the bathroom is saturated with humidity, even if the warm air from the bathroom heating unit 10 hits the body of the bather, the heat of vaporization will not be taken away from the body, so there is no feeling of cold wind. .

  In addition, during the mist preheating operation for a predetermined time before bathing in the mist sauna, only the heating operation is performed without performing the humidifying operation of the humidifying spray section 2 in the previous period, and in the latter period, the humidifying spray is performed together with the heating operation. The humidification operation of part 2 is performed. That is, even if the humidifying operation by the humidifying spray unit 2 is not performed throughout the entire period of the mist preheating operation, the humidification operation is performed in the latter period, so that the interior of the bathroom is saturated with humidity at the end of the mist preheating. can do. Accordingly, it is possible to prevent waste of energy for making water or humid air used for humidification in the bathroom, and to reduce the running cost of mist preheating.

Further, the humidifying spray unit 2 applies hot water to the heat exchanger 1 of the bathroom heating unit 10 to send wet air into the bathroom. That is, by making warm air by applying warm water to the heat exchanger 1, it is possible to take heat of vaporization from the heat exchanger 1 along with evaporation of warm water or the like. Therefore, the heat exchange capacity of the heat exchanger 1 is increased by making the best use of the heat dissipation capability of the heat exchanger 1 and increasing the amount of heat exchange that was limited in the heat exchange between the heat exchanger 1 and air. Can be improved.
Further, when humidity saturation in the bathroom is detected, the mist nozzle 18 is notified that mist spraying is possible (S10 and S16 in FIG. 2), so that the bather can immediately take a mist sauna bath by mist spraying. This is easy to use and is easy to use.

<Mist sauna operation>
Next, the mist sauna operation will be described.
The mist sauna operation may be performed together with the heating operation in the bathroom heating unit 10, but when the humidification operation may be performed immediately without performing the heating operation, This is an operation mode that may be executed when the temperature is sufficiently increased or when it is not necessary to perform the heating operation in advance depending on the season.
FIG. 3 shows an operation flow of the mist sauna operation. Referring to FIG. 3, first, when a mist sauna operation is commanded by bathroom remote controller 27 or kitchen remote controller 28, heat source unit 30, bathroom heating unit 10 and mist unit 20 start desired operations, and the above-described humidifying operation is performed. Is started (S21), the humid air heated from the bathroom heating unit 10 is blown out, and the inside of the bathroom is humidified and heated.

Then, when the humidification operation is continued and the humidity in the bathroom rises and the humidity sensor 5 detects the humidity saturation state in the bathroom (S22), the mist spray notice is notified by voice guidance or melody (S23). Then, mist spraying is started from the mist nozzle 18 (S24). Thereafter, the mist spraying is stopped when the mist switch is turned off or the mist timer expires (S25).
Even in this mist sauna operation, the mist spraying from the mist nozzle 18 is performed after the inside of the bathroom is saturated by the humidifying operation of the humidifying spray section 2, so that the mist is not vaporized even if mist spraying is performed. It does not take heat of vaporization from the air in the bathroom. Therefore, it is possible to prevent a temperature drop in the bathroom when the mist is sprayed from the mist nozzle 18 during bathing in the mist sauna. Moreover, even if the mist spraying from the mist nozzle 18 is interrupted and heating is continued, and the mist spraying from the mist nozzle 18 is started again, the inside of the bathroom is saturated with humidity by the above-described mist sauna operation operation. The temperature drop in the bathroom due to vaporization can be prevented.

  In addition, while the mist is sprayed from the mist nozzle 18, the humidifying operation of the humidifying spray section 2 (the operation of jetting warm water from the humidifying spray section 2 to the heat exchanger 1) may be stopped. That is, during the mist spray from the mist nozzle 18, even if the humidification operation is stopped, the humidity saturation state in the bathroom can be maintained by the mist spray from the mist nozzle 18. Therefore, during the mist spraying of the mist nozzle 18, the humidifying operation of the humidifying jet part 2 is stopped, thereby preventing the waste of energy for making water and humid air for humidification in the bathroom, and the mist sauna operation. The running cost can be reduced. In this case, switching between the humidifying operation and the mist spray may be performed based on humidity saturation detection by the humidity sensor 5.

Further, in the bathroom heating device with a mist sauna function, a ventilation unit including a ventilation fan may be provided in parallel with the bathroom heating unit, and the air in the bathroom may be ventilated to the outside by the operation of the ventilation fan. .
Further, in the mist preheating operation, whether the set time of the preheating operation is less than 5 minutes or less (S5 in FIG. 2) or whether the bath room temperature reaches the set temperature as the start condition of the humidifying operation in the later period (see FIG. However, the humidification operation may be started only when the remaining time is, for example, 5 minutes or less, or only when the bath room temperature reaches the set temperature.
