  Conventionally, in a hot water heating system comprising a heat source machine, a bathroom heating device for heating a bathroom using hot water circulated and supplied from the heat source machine, and a remote control for remotely operating the heat source machine, a remote control provided in a kitchen or the like And the bathroom heating device installed in the bathroom are configured to be able to communicate bidirectionally via a heat source unit, enabling the remote controller to start heating the bathroom, and the temperature of the bathroom reaches the set temperature by heating. In this case, a configuration has been proposed in which notification by a remote controller (notification that the bathroom temperature has reached an appropriate temperature) is performed (for example, see Patent Document 1).

  Moreover, the structure provided with the mist sauna function which produces the sauna effect by incorporating the mist spraying unit which sprays hot water from a mist nozzle in a bathroom heating device, and spraying hot water from a mist nozzle while heating a bathroom is proposed. (For example, refer to Patent Document 2).

JP 2002-195578 A JP 2011-52923 A

  In the bathroom heating device described in Patent Document 2, when the mist switch of the bathroom remote control is turned on, the mist sauna operation is performed by heating in the bathroom by the heating unit and spraying hot water into the bathroom by the mist spraying unit. Be started. And in this case, like the hot water heating system described in Patent Document 1, when the temperature in the bathroom reaches the set temperature, a notification is given and the bathroom is in a mist sauna state where the mist sauna is entering. It may be possible to inform the user that it has become.

  However, there is a possibility that the difference in the detected temperature of the temperature in the bathroom increases depending on the installation position of the temperature sensor or the like. In addition, for example, when the temperature of the bathroom at the start of mist sauna operation is relatively high due to the size of the bathroom or the outside air temperature, the bathroom is not sufficiently humid even though the bathroom has not reached sufficient humidity. The inside reaches the set temperature (for example, 33 ° C.) of the mist sauna within a short time. For this reason, if it is judged only that the temperature in the bathroom has reached the set temperature when the bathroom is in the mist sauna state, the notification may be performed even if the humidity in the bathroom is insufficient. There is.

  And there is an inconvenience that such inaccurate notification gives the user who bathes in the bathroom thinking that the mist sauna has entered.

  Therefore, it is conceivable to provide a timer that sets a time-up time corresponding to the mist sauna preparation time required for the inside of the bathroom to be in the mist sauna state, and to notify the completion of preparation of the mist sauna when this timer expires. . In this case, the time required for both the temperature and humidity in the bathroom to reach predetermined values is set as the mist sauna preparation time, and the mist sauna preparation time is set as the time-up time. By carrying out like this, alerting | reporting precision can be improved compared with the case where it judges only by the temperature in a bathroom having reached preset temperature.

  However, after the mist sauna operation is started, if the bathroom door is temporarily opened and closed before the timer expires, the temperature and humidity in the bathroom are temporarily lowered. For this reason, even if the timer expires, the temperature and humidity in the bathroom, which have temporarily decreased, do not rise sufficiently until the mist sauna state is reached, and there is a possibility that preparation completion of the mist sauna is notified in this state.

  An object of the present invention is to provide a bathroom heating device with a mist sauna function that eliminates such inconveniences and accurately determines the completion of preparation of the mist sauna to improve notification accuracy.

  In order to achieve such an object, the present invention provides a bathroom heating device with a mist sauna function for performing a mist sauna operation in which hot water is sprayed in a bathroom while heating the inside of the bathroom with warm air. The bathroom detects the temperature in the bathroom. Temperature detection means, humidity detection means for detecting the humidity in the bathroom, and time-up time corresponding to the mist sauna preparation time required for the bathroom to be in the mist sauna state are set in advance and timed at the start of mist sauna operation And a notification control means for notifying that the mist sauna is ready at least when the timer expires, the notification control means until the timer starts counting time In addition, the detected value of at least one of the temperature detected by the bathroom temperature detecting means and the humidity detected by the humidity detecting means decreases from an increase. When the value fluctuates so that it returns to the value just before it starts to decrease, the timer is timed up corresponding to the time from when the detected value returns to the value just before it starts decreasing. A time-up delay means for delaying is provided.

  In the above configuration, when the mist sauna operation is started, the timer starts operating. The start of the mist sauna operation can include, for example, when the user performs an operation for instructing the start of the mist sauna operation, or when the mist starts to be sprayed in the bathroom.

  When the timer expires, the notification control means notifies the completion of mist sauna preparation. The timer has a preset time-up time corresponding to the mist sauna preparation time required for the inside of the bathroom to be in the mist sauna state, so if the notification control means performs notification, the bathroom will enter the mist sauna. It is in a mist sauna state.

  On the other hand, the detection value of at least one of the temperature detected by the bathroom temperature detecting means and the humidity detected by the humidity detecting means changes from rising to falling until the timer expires and then decreases. It may fluctuate so as to return to the value immediately before the change to. Such a variation in the detected value is caused, for example, when a bathroom door is temporarily opened and closed by a user.

  Therefore, in the present invention, the time-up delay means delays the time-up of the timer corresponding to the time from when the detected value starts to decrease to when it returns to the value just before it starts to decrease. By doing this, even if the bathroom door is temporarily opened and closed while the timer is timing, the timer will not time out until the bathroom is in a mist sauna state, and the notification accuracy will be improved. Can do.

  Further, in the present invention, the notification control means has a mist sauna in which the timer expires and at least one of the detected temperature by the bathroom temperature detecting means and the detected humidity by the humidity detecting means is a mist sauna. It is preferable that the notification is performed when a predetermined value indicating the completion of preparation is reached.

  The detection value by the bathroom temperature detection means or the humidity detection means may cause an error depending on the installation position of the bathroom temperature detection means or the humidity detection means, and the detection value at the position where the bathroom temperature detection means or the humidity detection means is installed Even if it is equal to or greater than a predetermined value indicating completion of preparation of the mist sauna, the entire bathroom is not necessarily equal to or greater than the predetermined value indicating completion of preparation of the mist sauna. However, in the present invention, when the timer expires, when the detected value further exceeds a predetermined value, a notification is made, so that the mist sauna preparation completion is reliably confirmed from the detected value. And the notification accuracy can be further improved.

  Further, as one aspect of the time-up delay means in the present invention, the time-up delay means is configured such that when the detected value is changed from rising to falling until the timer starts counting time and time is up, A timer stop instructing means for instructing the timer to stop the time remaining until the time is up, and a value immediately before the detected value starts decreasing after the timer stops by the timer stop instructing means. When returning to, the timer is provided with a timing restart instruction means for instructing the timer to restart counting the remaining time.

  According to this aspect, after the timer starts operating, if the detected value turns from rising to falling before the timer expires, the remaining time until the timing stop instructing means times up to the timer is maintained. Instruct to stop timing. Thereafter, when the detected value returns to the value just before the decrease, the time restart instruction means instructs the timer to restart the remaining time. By doing so, the timer stops until the detection value returns to the value just before the detection value starts to decrease until the timer starts counting time, and the timer stops. The time-up can be delayed by the amount of time.

  As a result, even if the bathroom door is temporarily opened and closed while the timer is timing, the timer does not time out until the bathroom is in a mist sauna state, and the notification accuracy can be improved. .

  According to another aspect of the time-up delay means in the present invention, the time-up delay means starts to decrease after the detected value starts decreasing until the timer starts measuring time. The time-up time of the timer is corrected by adding the time taken by the time-of-fluctuation collecting means for collecting the time until returning to the previous value and the time taken by the time-varying time collecting means to a preset time-up time. And a time-up time correcting means.

  According to this aspect, after the timer starts operating, if the detected value changes from rising to falling before the timer expires, the fluctuation time collecting means returns to the value immediately before the detected value starts to decrease. Collect the time to change (variation time). Next, the time-up time correction unit corrects the time-up time by adding the time collected by the variable time collection unit to a preset time-up time. By doing so, the timer time-out can be delayed by the time from when the detected value starts to fall until the timer returns to the value just before it starts to fall before the timer starts counting time. it can.

  As a result, even if the bathroom door is temporarily opened and closed while the timer is timing, the timer does not time out until the bathroom is in a mist sauna state, and the notification accuracy can be improved. .

  The bathroom heating device with a mist sauna function of the present embodiment includes the heating unit 1 shown in FIG. 1 and a mist spraying unit not shown. As shown in FIG. 1, the heating unit 1 includes a housing 4 having a suction port 2 and a blowout port 3 formed on a lower surface thereof, and is disposed on a ceiling portion 6 of a bathroom 5.

  Inside the housing 4 of the heating unit 1, a ventilation case 7 that defines a ventilation path from the suction port 2 to the blowout port 3, and a ventilation case 7 that is arranged in the ventilation case 7 and that ventilates the air in the bathroom 5. A circulation fan 8 that circulates through an internal ventilation path and a heating radiator 9 that heats surrounding air are accommodated.

  Furthermore, a bathroom temperature sensor 10 (bathroom temperature detecting means) for detecting the room temperature of the bathroom 5 and a bathroom humidity sensor 11 (humidity) for detecting the humidity of the bathroom 5 are located near the suction port 2 of the casing 4 of the heating unit 1. Detecting means).

  In the present embodiment, a thermistor is used as the bathroom temperature sensor 10, and an absolute humidity sensor is used as the bathroom humidity sensor 11. Since the absolute humidity sensor is used as the bathroom humidity sensor 11, the absolute humidity of the bathroom can be directly detected.

  A relative humidity sensor may be used as the bathroom humidity sensor 11. When the relative humidity sensor is used, the saturated water vapor amount data for each temperature is stored in the memory in advance, and the detected relative humidity is converted into absolute humidity based on the detected temperature of the bathroom temperature sensor 10. .

  The circulation fan 8 forcibly takes in the air in the bathroom 5 from the suction port 2 into the ventilation case 7 and blows it out from the blowout port 3 to the bathroom 5. At this time, the heating radiator 9 heats the air in the bathroom 5 taken into the ventilation case 7 to generate hot air. Thereby, warm air blows out from the blower outlet 3, and the bathroom 5 is heated.

  The heating radiator 9 is connected to a heat medium forward pipe 12 and a heat medium return pipe 13 that constitute a part of the heat medium circulation path (not shown). Although not shown, the heating medium circulation path is connected to a heating heat exchanger that is heated by a heating burner of the heat source machine, and a heating medium made of water, an antifreeze liquid, or the like circulates in the heating medium circulation path.

  The mist spraying unit includes a mist nozzle 14 and a mist water channel 15 connected to the mist nozzle 14. The mist nozzle 14 is provided in the housing 4 of the heating unit 1 and sprays hot water on the bathroom 5 together with warm air. Although not shown, the mist channel 15 is connected to a liquid-liquid heat exchanger that exchanges heat with the heat medium in the heat medium circuit, and water for mist such as tap water flowing through the mist channel 15 is used as the heat medium. It is heated by the heat medium in the circulation path through the liquid-liquid heat exchanger.

  In addition, a heating controller 16 that controls the heating unit 1 and the mist spray unit is provided inside the housing 4.

  The heating controller 16 is an electronic unit composed of a CPU, a memory, and the like, and executes a heating operation and a mist sauna operation as shown in FIG. 2 by executing a control program held in the memory by the CPU. A heating operation control unit 17, a notification control unit 18 (notification control means in the present invention) for performing control for notifying completion of preparation of the mist sauna when the bathroom 5 is in a mist sauna state, and a mist sauna operation A function as an operation timer 19 for measuring the execution time is provided.

  The notification control unit 18 is a mist sauna preparation timer 20 (timer in the present invention) that measures the preparation time until the bathroom 5 is in a mist sauna state, and a time-up time setting unit that sets a time-up time of the mist sauna preparation timer 20 21. A time-up delay processing unit 22 (time-up delay means) that performs a process of delaying the time-up of the mist sauna preparation timer 20 is provided as a function. The time-up delay processing unit 22 in the present embodiment is not illustrated, but is a timing stop instruction means for instructing the mist sauna preparation timer 20 to stop timing and a timing restart instruction means for instructing the mist sauna preparation timer 20 to restart timing. Function.

  The heating controller 16 is communicably connected to a heat source controller 23 provided in the above-described heat source machine. A bathroom remote controller 24 and a kitchen remote controller 25 are communicably connected to the heat source controller 23.

  When the start of the mist sauna operation is instructed by the operation of the mist switch (not shown) of the bathroom remote controller 24, the signal is transmitted to the heating controller 16 via the heat source controller 23, and the mist sauna operation is started.

And the heating controller 16 performs the process which performs the alerting | reporting by the bathroom remote control 24 and the kitchen remote control 25 at the timing when the inside of the bathroom 5 became a mist sauna state (for example, room temperature 33 degreeC or more and absolute humidity 30g / m < ³ >). To do. Hereinafter, this process will be described with reference to the flowchart shown in FIG. Although not shown, the bathroom remote controller 24 and the kitchen remote controller 25 are each provided with a voice alarm and an LED alarm lamp.

  When the mist switch of the bathroom remote controller 24 is turned on, the heating controller 16 recognizes a mist sauna operation start instruction in STEP 1 of FIG. 3 and proceeds to STEP 2.

  In STEP 2, the time-up time setting unit 21 sets a time-up time corresponding to the temperature detected by the bathroom temperature sensor 10 based on a data table stored in advance. In the relationship between the bathroom temperature and the time-up time in the data table, a longer time-up time corresponds to a lower bathroom temperature.

  In subsequent STEP3, the operation timer 19 is started. The operation timer 19 has a mist sauna operation execution time as a time-up time. The execution time of the mist sauna operation can be set by operating the bathroom remote control 24, and the initial setting is 1 hour.

  Next, in STEP 4, the heating operation control unit 17 starts the mist sauna operation, and the hot air heating in the bathroom 5 and the spray from the mist nozzle 14 are started. Thereby, the temperature and humidity of the bathroom 5 gradually increase.

  Next, in STEP 5, the notification control unit 18 starts the mist sauna preparation timer 20 and waits for the time up of the mist sauna preparation timer 20 in subsequent STEP 6.

Then, when the mist sauna preparation timer 20 expires in STEP 6, the process proceeds to STEP 7. When the detected humidity of the bathroom humidity sensor 11 is greater than or equal to a predetermined value (in this embodiment, absolute humidity 30 g / m ³ ) indicating that the mist sauna is ready in STEP 7, the notification control unit 18 proceeds to STEP 8 and proceeds to STEP 8. 24 and the kitchen remote control 25 are instructed to notify the mist sauna preparation completion.

  As a result, the bathroom remote controller 24 and the kitchen remote controller 25 perform notification (such as turning on an LED or outputting a voice saying “Mist sauna is ready”) informing that the mist sauna is ready.

  Thereafter, when the operation timer expires in STEP 9, the operation proceeds to STEP 10, where the heating operation control unit 17 stops the warm air heating in the bathroom 5 and the spray from the mist nozzle 14, and the process is terminated.

  On the other hand, if the detected temperature of the bathroom temperature sensor 10 changes from increasing to decreasing in STEP 11 while waiting for the mist sauna preparation timer 20 to time up in STEP 6, the process proceeds to STEP 12. The reason that the detected temperature of the bathroom temperature sensor 10 changes from increasing to decreasing in STEP 11 may be that the door of the bathroom 5 is opened or closed.

  Then, when proceeding to STEP 12, the mist sauna preparation timer 20 stops timing in accordance with an instruction from the timing stop instruction means which is a function of the time-up delay processing unit 22. At this time, the timing stop instruction means stops the mist sauna preparation timer 20 while maintaining the remaining time until the mist sauna preparation timer 20 expires.

  Thereafter, when the bathroom temperature sensor 10 detects the return to the temperature immediately before the temperature drop of the bathroom 5 in STEP 13, the process proceeds to STEP 14. Then, when proceeding to STEP 14, the mist sauna preparation timer 20 resumes timing in accordance with an instruction from the timing restart instruction means which is a function of the time-up delay processing unit 22, and returns to STEP 6. At this time, the mist sauna preparation timer 20 measures the remaining time until the time is up at the time when the time measurement is stopped in STEP 12.

  By doing so, even if the temperature of the bathroom 5 is temporarily lowered while the door of the bathroom 5 is opened and closed while the mist sauna preparation timer 20 is timing, the mist sauna is still being used while the temperature is lowered. Timing of the preparation timer 20 is stopped. Therefore, the time up of the mist sauna preparation timer 20 results in a delayed state, and the mist sauna preparation timer 20 does not time up before the bathroom 5 enters the mist sauna state.

  In this embodiment, the detected humidity of the bathroom humidity sensor 11 is used in STEP 7, but the detected temperature of the bathroom temperature sensor 10 may be used instead, or the detection of the bathroom temperature sensor 10 may be used. Both the temperature and the humidity detected by the bathroom humidity sensor 11 may be used.

  In this embodiment, the detected temperature of the bathroom temperature sensor 10 is used in STEP 11 and STEP 13, but the detected humidity of the bathroom humidity sensor 11 may be used instead, or the bathroom temperature sensor. Both the detected temperature of 10 and the detected humidity of the bathroom humidity sensor 11 may be used.

  Next, another embodiment will be described. In other embodiments, in the notification control unit 18 shown in FIG. 2, only the configuration of the time-up delay processing unit 22 (time-up delay means) is different, and other configurations are the same as those of the above-described embodiment.

  Although not shown in the figure, the time-up delay processing unit 22 in another embodiment displays the time (timer time T1) of the mist sauna preparation timer 20 at that time when the temperature detected by the bathroom temperature sensor 10 changes from rising to lowering. When the detected temperature of the bathroom temperature sensor 10 returns to the temperature just before the decrease, the time measured by the mist sauna preparation timer 20 (timer time T2) at that time is stored, and the timer time T1 and the timer time T2 are further stored. The variable time collecting means for collecting the variable time by calculating the time difference, and the time-up time by adding the above-mentioned variable time to the time-up time of the mist sauna preparation timer 20 previously set in the time-up time setting unit 21 It functions as time-up time correcting means for correcting.

  The processing of the notification control unit 18 in another embodiment configured as described above will be described according to the flowchart shown in FIG.

  In FIG. 4, STEP1 to STEP10 are the same as the flowchart of FIG.

  Referring to FIG. 4, when the detected temperature of bathroom temperature sensor 10 changes from rising to lowering in STEP 15 while waiting for time-up of mist sauna preparation timer 20 in STEP 6, the process proceeds to STEP 16, and a time-up delay processing unit The time period T1 at that time is stored by the fluctuating time sampling means which is the function of 22.

  Thereafter, when the bathroom temperature sensor 10 detects the return to the temperature just before the temperature drop of the bathroom 5 in STEP 17, the process proceeds to STEP 18 and the time-of-time sampling means which is a function of the time-up delay processing unit 22 performs the timer at that time. Store time T2.

  Next, proceeding to STEP 19, the variation time collecting means calculates the time difference between the timer time T1 and the timer time T2 as the variation time, and proceeds to STEP20. When proceeding to STEP 20, the time-up time correcting means, which is a function of the time-up delay processing unit 22, corrects the time-up time of the mist sauna preparation timer 20 set in STEP 2, and returns to STEP 6.

  Specifically, the processing by the time-up time correcting means in STEP 20 corrects the time-up time by adding the variation time calculated in STEP 19 to the time-up time set in STEP 2. By doing so, even if the door of the bathroom 5 is opened and closed while the mist sauna preparation timer 20 is timing and the temperature of the bathroom 5 is temporarily lowered, the time during which the temperature is lowered (variation time) ) And the time-up time of the mist sauna preparation timer 20 is delayed as a result. As a result, the mist sauna preparation timer 20 does not time up before the bathroom 5 enters the mist sauna state.

  In STEP16 and STEP18, the mist sauna preparation timer 20 is used to calculate the fluctuation time, but instead, the detected temperature of the bathroom temperature sensor 10 is changed from rising to lowering to the temperature immediately before the lowering. The notification control unit 18 may be provided with time measuring means for measuring the time until returning. According to this, it is possible to collect the fluctuation time without performing an operation for calculating the time difference between the timer time T1 and the timer time T2.

  In other embodiments, the detected temperature of the bathroom temperature sensor 10 is used in STEP 15 and STEP 17, but the detected humidity of the bathroom humidity sensor 11 may be used instead, or the bathroom temperature may be used. Both the detected temperature of the sensor 10 and the detected humidity of the bathroom humidity sensor 11 may be used.
