Description

  The present invention relates to a mist sauna apparatus provided with hot water supply means for supplying hot water to spray means for spraying hot water in a mist form in a sauna space, and operation control means for controlling the operation of the hot water supply means.

As the mist sauna apparatus as described above, there is one provided with operation control means for adjusting the temperature of hot water supplied by the hot water supply means in order to keep the sauna space in a comfortable state (see, for example, Patent Document 1). .
In the mist sauna device of Patent Document 1, when the start of mist operation is instructed, the heat source unit is operated and the liquid-to-liquid heat exchanger side proportional valve is opened, so that the heat source unit to the liquid-to-liquid heat exchanger is opened. Start supplying heat medium. After that, when the detected temperature of the heat medium thermistor becomes equal to or higher than the set temperature for heating and a heatable state is detected, the hot water intermittent valve and the water amount adjustment valve are opened to start the supply of hot water to the mist spraying section. The flow rate of the hot water to the liquid-to-liquid heat exchanger is adjusted by adjusting the opening of the water amount adjustment valve so that the detected temperature of the tapping temperature thermistor becomes the mist set temperature. In this way, while adjusting the flow rate of the hot water to the liquid-to-liquid heat exchanger until the mist operation switch is turned OFF, the hot water having the mist set temperature is jetted into the bathroom in a mist form.

Incidentally, conventionally, some mist sauna apparatuses employ an operation method in which the control method of the hot water temperature is switched before and after the temperature of the sauna space reaches the target temperature. In particular,
From the start of operation until the temperature of the sauna space reaches the target temperature, the amount of heat applied to the sauna space by the hot water sprayed from the spray means is high enough to increase the temperature of the sauna space. When the start-up operation is performed to operate the hot water supply means so that the temperature of the sauna space reaches the target temperature, the amount of heat given to the sauna space by the hot water sprayed from the spray means is the temperature of the sauna space. An operation method is adopted in which a bath operation is performed in which the hot water supply means is operated so that an appropriate amount of applied heat can be maintained at a target temperature.

  The mist sauna device is superior in that it can provide comfort as a sauna with high-temperature mist sprayed, but the sprayed mist aggregates before completely releasing the amount of heat it holds, and is discharged as waste water as it is As a result, the wastewater containing the amount of heat is discharged, and the thermal energy corresponding to the amount of wastewater is discarded.

Under such circumstances, there is a problem that running cost is high when using the mist sauna device. That is, as long as the sprayed mist aggregates into a liquid and has a certain amount of heat, the amount of heat discarded as wastewater is considerable, and the conventional mist sauna device can reduce the running cost sufficiently. There is room for improvement in reducing running costs when using mist saunas.
In view of the above circumstances, an object of the present invention is to provide an economical mist sauna device capable of suppressing running costs while maintaining the comfort of a mist sauna.

  A first feature of the present invention is a mist sauna provided with warm water supply means for supplying warm water to spray means for spraying warm water in a mist form in a sauna space, and operation control means for controlling the operation of the warm water supply means. In the apparatus, the amount of heat applied to the sauna space by the hot water sprayed from the spray means until the temperature of the sauna space reaches a target temperature from the start of operation until the operation control means starts high operation. Start-up operation processing for operating the hot water supply means so as to give the amount of applied heat, and the sauna space by the hot water sprayed from the spray means to maintain the temperature of the sauna space at the target temperature In the bath operation process, a jet that changes the temperature of the hot water sprayed from the spray means is configured to execute a bath operation process that adjusts the amount of heat applied. In that it is switched freely configured and the temperature control state from the spray means and the spray amount control state for changing the amount of hot water to be sprayed.

According to the first feature of the present invention, the start-up operation process is executed until the temperature of the sauna space reaches the target temperature, and the amount of heat applied to the sauna space by the hot water sprayed from the spray means is increased. Therefore, when the mist sauna is used, the temperature of the sauna space can be set to the target temperature in a short time.
And, since the operation control means is configured to be switchable between the spray temperature control state and the spray amount control state in the bath operation process, depending on the environmental conditions in which the mist sauna device is used, whichever one is appropriate The bath operation process can be executed by selecting the control state.

For example, when using a mist sauna device in a hot and humid environment in summer, the comfort of the mist sauna is not impaired even if the amount of hot water sprayed in the mist sauna space changes slightly. If it is a use environment, a bath operation process may be executed in a spray amount control state to maintain the target temperature. In this case, since the amount of warm water sprayed from the spraying means can be adjusted to suppress the generation of waste water having a calorific value, the running cost can be reduced without impairing the comfort of the mist sauna felt in the environment. Can be suppressed.
In addition, when the mist sauna device is used in a low-temperature and low-humidity environment in winter, the environment in which the comfort of the mist sauna is likely to be impaired if the amount of hot water sprayed in the mist sauna space changes. If so, the target temperature may be maintained by executing the bath operation process in the spray temperature control state. In this case, since the temperature of the hot water sprayed from the spraying means can be adjusted to suppress the generation of waste water having a calorific value, the running cost can be reduced without impairing the comfort of the mist sauna felt in the environment. Can be suppressed.
When using a mist sauna device in a low-temperature and low-humidity environment in winter, the amount of heat taken outside from the sauna space is relatively large, so compare the amount of heat given by the sprayed hot water. Most of the energy is thought to be released to maintain the sauna space at the target temperature, so the thermal energy that is discarded as wastewater is less than the amount of wastewater.

  As described above, according to the first feature of the present invention, by switching the operation control state in the bath operation process to an appropriate one according to the use environment, it is possible to suppress the running cost while maintaining the comfort of the mist sauna. Mist sauna equipment can be obtained.

  According to a second aspect of the present invention, in the first aspect of the present invention, there is provided thermal load detection means for detecting the amount of heat taken outside from the sauna space, wherein the operation control means is the bath operation. In the processing, when it is determined that the high load state with a large amount of captured heat is determined based on the detection information of the thermal load detection means, the amount of heat applied to the sauna space is adjusted by the spray temperature control state. And when it determines that it is a low load state with a small amount of heat taken, based on detection information of the thermal load detection means, the amount of heat applied to the sauna space is adjusted by the spray amount control state. It is in the point comprised as follows.

According to the 2nd characteristic of this invention, it has the same effect as the 1st characteristic of this invention, and also has the following effects in addition to this.
According to the second feature of the present invention, the thermal load detection means detects the amount of heat taken away from the sauna space, and the operation state of the operation control means is based on the detection information of the thermal load detection means. Since the spray temperature control state and the spray amount control state are automatically switched according to the determined load state, the operation state of the bath operation process is automatically set in the low load state such as summer. When the spray amount control state is switched to a high load state such as winter, the operation state of the bath operation process is automatically switched to the spray temperature control state. Therefore, the user can unconsciously save the operating cost without having to bother switching the driving state according to the usage environment.

According to the third feature of the present invention, the thermal load detecting means detects the amount of heat taken away based on the temperature of the drainage discharged from the sauna space. The drainage discharged from the sauna space is generated as a result of the mist filling the sauna space being agglomerated due to a decrease in temperature or the like, so the amount of heat imparted to the sauna space by the hot water sprayed from the spray means is reduced. If you know, by measuring the temperature of the waste water, you can see how much of the heat given to the sauna space was consumed to compensate for the amount of heat taken outside from the sauna space. It can be grasped indirectly. Further, the temperature of the waste water can be measured with a simple configuration such as providing a temperature measuring means such as a thermistor or a water temperature meter in the flow path from which the waste water is discharged.

Then, the direction of the movable louver 16 is adjusted by operating the ventilation electric motor so that the blowing direction of the air into the bathroom 1 is almost directly below the drying blowing direction.

In the cool air operation, the circulation fan 2 is operated in a state where the air-conditioning heat medium interrupting valve 27 is kept closed, and the ventilation fan 18 is operated so that a part of the air sucked from the bathroom 1 is discharged into the exhaust duct 17. The air sucked from the inside of the bathroom 1 is blown into the bathroom 1 through the circulation ventilation path 15 without being heated while being discharged to the outside.
Then, the direction of the movable louver 16 is adjusted by operating the ventilation motor so that the blowing direction of the air into the bathroom 1 becomes the blowing direction for cool air (for example, the direction toward the washing place). .

In the mist operation, when the mist operation switch 35 is turned ON and the start of the mist operation is instructed, the heat source unit 9 is operated and the supply of hot water from the heat source unit 9 to the mist ejection unit 5 is started. The mist hot water interrupting valve 7 and the water amount adjusting valve 29 are opened. Thus, the hot water supplied through the mist hot water supply passage 22 is jetted into the bathroom 1 in the form of mist in the mist jetting section 5.
At this time, while adjusting the opening amount of the water amount adjustment valve 29 so that the temperature Tr in the bathroom 1 becomes the target temperature Tt (for example, 40 ° C.), the amount of hot water supplied to the mist ejection unit 5 is adjusted, Based on the temperature detected by the mist hot water temperature thermistor 30, the hot water heating operation of the heat source unit 9 is controlled to adjust the temperature of the hot water supplied to the mist ejection unit 5.
Incidentally, the ejection direction of the ejection nozzle 5a is configured to be changeable by a setting switch of the remote control operation unit R, and specifically, the electric motor M for mist is operated and the hot water supply pipe 5b is moved around the horizontal axis. It is comprised so that it may rotate and the ejection direction of the ejection nozzle 5a may be changed.
When the mist operation is started, the heating operation such as the speed heating operation is started at the same time, the bathroom temperature Tr can be set to the target temperature Tt in as short a time as possible, and the exhaust heat from the drainage until the target temperature Tt is reached can be as much as possible. It has come to decrease. In addition, after the bathroom temperature Tr reaches the target temperature Tt, the strong heating operation or the weak heating operation is performed simultaneously with the spraying of hot water, and the bathroom temperature Tr is close to the target temperature Tt in a state where exhaust heat due to drainage is minimized. To be maintained.

  The operation of the control unit H in the mist operation will be described based on the flowchart of FIG. First, when the mist operation switch 35 is turned ON and the start of mist operation is instructed, a start-up operation process for setting the bathroom temperature Tr to the target temperature Tt is performed (step # 1 to step # 2).

When the start-up operation process is completed, one of the two bath operation processes with different control states is performed based on the measurement information of the drain temperature sensor Sd until the mist operation switch 35 is turned OFF and a stop command is issued. One process is executed (step # 3 to step # 8).
That is, when the drainage temperature Td is higher than a preset threshold value Tc, a hot water amount control bath operation process, which is a bath operation process when the bathroom 1 is in a low heat negative state, is executed, and hot water sprayed on the bathroom 1 By adjusting the amount, the amount of heat applied to the bathroom 1 is adjusted, and a control state in which control is performed such that the bathroom temperature Tr is maintained at the target temperature Tt is prioritized, and the drain temperature Td is a preset threshold value Tc. If the temperature is lower, a hot water temperature control bath operation process that is a bath operation process when the bathroom 1 is in a high heat negative state is executed, and the amount of hot water sprayed on the bathroom 1 is adjusted to be given to the bathroom 1. In such a control state, priority is given to the control of adjusting the amount of heat to maintain the bathroom temperature Tr at the target temperature Tt.

  In this way, the control unit H gives a high amount of heat for starting up the amount of heat applied to the bathroom 1 by the hot water sprayed from the mist spraying unit 5 from the start of operation until the temperature Tr of the bathroom 1 reaches the target temperature Tt. The start-up operation process for controlling the operation of the heat source unit 9 or the like is executed so that the amount of heat is obtained, and after the temperature Tr of the bathroom 1 reaches the target temperature Tt, the temperature Tr of the bathroom 1 is maintained at the target temperature Tt. Therefore, it is comprised so that the bath operation process which adjusts the calorie | heat amount given to the bathroom 1 with the hot water sprayed from the mist ejection part 5 may be performed, and in the bath operation process, the warm water sprayed from the mist ejection part 5 Switchable between a spray temperature control state for changing the temperature of the water and a spray amount control state for changing the amount of hot water sprayed from the mist ejecting section 5, and a large amount of heat is taken based on the detection information of the drainage temperature sensor Sd. High negative When it is determined that the state is a state, the amount of heat applied to the bathroom 1 is adjusted according to the spray temperature control state, and the amount of heat taken is low based on the detection information of the drain temperature sensor Sd. Is determined, the amount of heat applied to the bathroom 1 is adjusted according to the spray amount control state.

  The start-up operation process in step # 2 in FIG. 5 will be described based on the flowchart shown in FIG. As shown in FIG. 6, first, the heating operation mode M is set to the speed heating operation mode M1, and the aforementioned speed heating operation is started (step # 21). The target hot water temperature T is set to Th (for example, 65 ° C.), and the target hot water supply amount V is set to Vb (for example, 1.0 [l / min]) (step # 22 to step # 23). Thereafter, until the bathroom temperature Tr reaches the target temperature Tt, the heating operation of the heat source unit 9 is controlled so that the temperature of the hot water supplied from the heat source unit 9 becomes the set target hot water temperature Th, and mist ejection The opening / closing operation of the water amount adjusting valve 29 is controlled so that the amount of hot water sprayed from the unit 5 becomes the set target hot water amount Vb (step # 24). When the bathroom temperature Tr reaches the target temperature Tt, the heating operation mode M is changed from the speed heating operation mode M1 to the strong heating operation mode M2 (step # 25), and the start-up operation process is ended.

  The hot water amount control bath operation processing in step # 4 in FIG. 5 will be described based on the flowchart shown in FIG. First, in step # V1, the state of the amount adjustment lower limit flag F1 is determined. The amount adjustment lower limit flag F1 is off in the initial state and is reset to off, which is the initial state when the mist operation process ends (see step # 8 in FIG. 5), so when the mist operation is started. The state of the amount adjustment lower limit flag F1 is off. Accordingly, after the warm water amount control bath operation process is started, the process proceeds to step # V3 after the determination process in step # V1 until the amount adjustment lower limit flag F1 is changed to the ON state in step # V8.

After the bathroom temperature Tr reaches the target temperature Tt by the start-up operation process, Vs (for example, 0.5 [l / min]) is set as the target hot water supply amount V (step # V1 → step # V3 → step # V5 → step). # V6 → Step #VR), this setting state continues until the bathroom temperature Tr falls below the target temperature Tt (Step # V1, Step # V3, Step # V5, Step # V7, Step #VR), and Bathroom 1 The amount of warm water supplied from the heat source unit 9 is adjusted by controlling the opening and closing of the water amount adjustment valve 29 so that the amount of warm water sprayed on the surface becomes Vs.
When the bathroom temperature Tr falls below the target temperature Tt, the same Vb as the target hot water supply amount V during start-up operation is set as the target hot water supply amount V (step # V1 → step # V3 → step # V4 → step #VR). ) The amount of hot water supplied from the heat source unit 9 is adjusted by controlling the opening and closing of the water amount adjustment valve 29 so that the amount of hot water sprayed on the bathroom 1 becomes Vb set as the target hot water supply amount V. The
When the bathroom temperature Tr recovers and exceeds the target temperature Tt, Vs is set again as the target hot water supply amount V (step # V1 → step # V3 → step # V5 → step # V6 → step #VR).

  In this way, when the bathroom temperature Tr exceeds the target temperature Tt, the amount of hot water sprayed is reduced to reduce the amount of heat applied to the bathroom 1, and when the bathroom temperature Tr falls below the target temperature Tt, the bathroom 1 In order to increase the amount of heat applied, control is performed such that the amount of hot water sprayed is increased and the bathroom temperature Tr is maintained near the target temperature Tt. That is, the control unit H changes the amount of hot water sprayed with the amount of heat applied to the bathroom 1 by the hot water sprayed from the mist spraying unit 5 in order to maintain the temperature Tr of the bathroom 1 at the target temperature Tt. It is comprised so that the operation process for baths may be performed in the spray amount adjustment state to adjust.

Since the heat load state of the bathroom 1 is low, when the amount of heat applied by the hot water sprayed with the target hot water supply amount V set to Vs is excessive, the amount of heat applied to the bathroom 1 is further increased. In order to reduce, the temperature of the hot water supplied from the heat source device 9 is adjusted.
That is, when it is determined that the state in which the bathroom temperature Tr exceeds the target temperature Tt continues for a predetermined time after the target hot water supply amount V is changed from Vb to Vs (step # V7), the amount adjustment lower limit flag F1 is turned on. (Step # V8), the temperature of the hot water supplied from the heat source unit 9 is adjusted (Step # V9 to Step # V14).

  After the bathroom temperature Tr reaches the target temperature Tt by the start-up operation process, the amount adjustment lower limit flag F1 is changed to the ON state while attempting to maintain the target temperature Tt by changing the target hot water supply amount V. The warm water amount control bath operation process is a process in which the process proceeds from step # V1 to step # V2. Therefore, once the amount adjustment lower limit flag F1 is changed to the on state, the processing of step # V3 to step # V8 is not executed, and the state where the target hot water supply amount V is set to Vs is maintained.

  The temperature adjustment lower limit flag F2 is off in the initial state, and is reset to off, which is the initial state when the mist operation process ends (see step # 8 in FIG. 5), so when the mist operation is started. The state of the flag F2 is off. Therefore, from the time when the amount adjustment lower limit flag F1 is changed to the on state until the temperature adjustment lower limit flag F2 is changed to the on state, the process proceeds to step # V9 after the determination process at step # V2. .

  Until the bathroom temperature Tr falls below the target temperature Tt, Tm (for example, 60 ° C.) is set as the target hot water temperature T (step # V1, step # V2, step # V9, step # V11, step # V12, step #VR). This setting state continues (step # V1 → step # V2 → step # V9 → step # V11 → step # V13 → step #VR) so that the temperature of the hot water sprayed on the bathroom 1 becomes Tm. The heating operation of the heat source unit 9 is controlled, and the temperature of the hot water supplied from the heat source unit 9 is adjusted.

When the bathroom temperature Tr falls below the target temperature Tt, the same Th as the target hot water temperature T during start-up operation is set as the target hot water temperature T (Step # V1 → Step # V2 → Step # V9 → Step # V10 → Step) #VR) The heating operation of the heat source unit 9 is controlled and the temperature of the hot water supplied from the heat source unit 9 is adjusted so that the temperature of the hot water sprayed on the bathroom 1 becomes Th.
When the bathroom temperature Tr recovers and exceeds the target temperature Tt, Tm is set again as the target hot water temperature T (step # V1, step # V2, step # V9, step # V11, step # V12, step #). VR).

  Since the heat load state of the bathroom 1 is low, when the amount of heat applied by the hot water sprayed with the target hot water temperature T set to Tm is excessive, the amount of heat applied to the bathroom 1 is further reduced. Therefore, the target hot water temperature T is set to TL (for example, 55 ° C.), and the temperature of the hot water supplied from the heat source unit 9 is adjusted. That is, when it is determined that the state where the bathroom temperature Tr exceeds the target temperature Tt has continued for a predetermined time after the target hot water temperature T is changed from Th to Tm, the target hot water temperature T is set to TL (step # V1). → Step # V2 → Step # V9 → Step # V11 → Step # V13 → Step # V14 → Step # V15 → Step #VR).

This setting state continues until the bathroom temperature Tr falls below the target temperature Tt (step # V1, step # V2, step # V9, step # V11, step # V13, step # V14, step # V16, step). #VR) The heating operation of the heat source unit 9 is controlled to adjust the temperature of the hot water supplied from the heat source unit 9 so that the temperature of the hot water sprayed on the bathroom 1 becomes TL.
When the bathroom temperature Tr falls below the target temperature Tt, Th is set again as the target hot water temperature T (step # V1 → step # V2 → step # V9 → step # V10 → step #VR) and sprayed on the bathroom 1. The temperature of the hot water supplied from the heat source device 9 is adjusted by controlling the heating operation of the heat source device 9 so that the temperature of the hot water becomes Th.
When the bathroom temperature Tr recovers and exceeds the target temperature Tt, Tm is set again as the target hot water temperature T (step # V1, step # V2, step # V9, step # V11, step # V12, step #). VR).

  Thus, since the heat load state of the bathroom 1 is low, even if the set value of the target hot water supply amount V is Vs, if the bathroom temperature Tr does not fall below the target temperature Tt, the amount of heat applied to the bathroom 1 If the temperature of the sprayed hot water is lowered and the bathroom temperature Tr falls below the target temperature Tt, the temperature of the sprayed hot water is increased to increase the amount of heat applied to the bathroom 1, and the bathroom temperature Tr Is controlled in the vicinity of the target temperature Tt. That is, when the controller H performs the hot water amount control bathroom operation process, the amount of heat applied to the bathroom 1 is excessive even if the amount of hot water sprayed from the mist sprayer 5 is the lower limit of the amount adjustment range. In this case, the control state is the spray temperature adjustment state, and the temperature of the hot water is adjusted.

Furthermore, since the heat load state of the bathroom 1 is low, when the amount of heat given by the hot water sprayed with the target hot water temperature T set to TL is excessive, the amount of heat given to the bathroom 1 is In order to further reduce, the heating operation mode M is switched from the strong heating operation mode M2 to the weak heating operation mode M3, and the operations of the heat source unit 9 and the circulation fan 2 are controlled to the weak heating state.
That is, when it is determined that the state where the bathroom temperature Tr exceeds the target temperature Tt has continued for a predetermined time after the target hot water temperature T is changed from Tm to TL (step # V16), the temperature adjustment lower limit flag F2 is turned on. It is changed (step # V17), and the amount of heat applied by the heating operation is adjusted (step # V18 to step # V21).

  When the temperature adjustment lower limit flag F2 is changed to the ON state, the hot water amount control bath operation process is a process in which the process proceeds from step # V1 to step # V18 through step # V2. Therefore, once the temperature adjustment lower limit flag F2 is changed to the on state, the processing of step # V9 to step # V17 is not executed, and the target hot water temperature T is maintained in the state set to TL.

Until the bathroom temperature Tr falls below the target temperature Tt, the heating operation mode M is set to the weak heating operation mode M3 (step # V1, step # V2, step # V18, step # V20, step # V21, step #VR). This setting state continues (step # V1 → step # V2 → step # V18 → step # V20 → step #VR), and the weak heating operation is performed.
When the bathroom temperature Tr recovers and exceeds the target temperature Tt, the heating operation mode M is set again to the strong heating operation mode M2 (step # V1, step # V2, step # V18, step # V19, step #). VR).

  Thus, since the heat load state of the bathroom 1 is low, even if the set value of the target hot water supply amount V is set to Vs and the set value of the target hot water temperature T is set to TL, the bathroom temperature Tr falls below the target temperature Tt. If not, the heating operation mode M is switched from the strong heating operation mode M2 to the weak heating operation mode M3 to reduce the amount of heat applied to the bathroom 1, and when the bathroom temperature Tr falls below the target temperature Tt, the heating operation mode M is applied to the bathroom 1. In order to increase the amount of heat generated, the heating operation mode M is switched from the weak heating operation mode M3 to the strong heating operation mode M2, and control is performed such that the bathroom temperature Tr is maintained near the target temperature Tt. That is, when the amount of heat given to the bathroom 1 is adjusted according to the spray amount control state, the control unit H is given to the bathroom 1 even if the amount of hot water sprayed from the mist spraying portion is the lower limit of the amount adjustment range. In the case where the temperature of the hot water is adjusted because of the excessive amount of heat to be generated, if the amount of heat applied to the bathroom 1 is excessive even if the temperature of the hot water is set to the lower limit of the temperature adjustment range, It is comprised so that the calorie | heat amount provided to may be adjusted.

  As described above, in the hot water amount control bath operation process of Step # 4 in FIG. 5, the control unit H sets Vb or Vs as the target hot water supply amount V, and Th, Tm, or TL as the target hot water temperature T. Therefore, there are four setting states of Zbh, Zsh, Zsm, and ZsL as shown in FIG. 9 for the target hot water supply amount V and the target hot water temperature T. Then, when the hot water amount control bath operation process is executed to maintain the bathroom temperature Tr at the target temperature Tt, the control unit H determines that the target hot water supply amount V and the target hot water supply amount V are changed until the amount adjustment lower limit flag F1 is turned on. The set state of the target hot water temperature T becomes a spray amount control state in which the setting state changes between the state Zbh and the state Zsh (change indicated by a white arrow in FIG. 9: Zbh⇔Zsh), and the amount adjustment lower limit flag F1 is changed to the on state. Until the temperature adjustment lower limit flag F2 is changed to the ON state, the setting state of the target hot water supply amount V and the target hot water temperature T changes among the states Zsh, Zsm, and ZsL (changes indicated by white arrows in FIG. 9). : Zsh⇔Zsm⇔ZsL). When the temperature adjustment lower limit flag F2 is changed to the ON state, the set values of the target hot water supply amount V and the target hot water temperature T are maintained in the state ZsL until the mist operation is stopped.

  In any of the above-described four setting states in the hot water amount control bath operation process, the control unit H is in the strong heating operation mode M2, and the strong heating operation is performed in parallel. When the state is the state ZsL, when the amount of heat applied to the bathroom 1 is excessive, the heating operation mode M is switched from the strong heating operation mode M2 to the weak heating operation mode M3, and the weak heating operation is performed concurrently. It will be.

  Next, the hot water temperature control bath operation process in step # 6 of FIG. 5 will be described based on the flowchart shown in FIG.

  As shown in FIG. 8, steps # T1 and # T3 to # T11 of the hot water temperature control bath operation processing are the same as steps # V2 and # V9 to # V17 of the hot water amount control bath operation processing. The steps # T2 and # T12 to # T17 of the hot water temperature control bath operation processing are the same as the steps # V1 and # V3 to # V8 of the hot water amount control bath operation processing, and the hot water temperature control bath operation is performed. Processes in steps # T18 to # T21 are the same as steps # T18 to # T21 in the hot water amount control bath operation process.

  That is, the order of the process of adjusting the amount of heat applied to the bathroom 1 by changing the setting of the target hot water temperature T and the process of adjusting the amount of heat applied to the bathroom 1 by changing the setting of the target hot water supply amount V There is no difference in the content of each process except that is replaced. Therefore, a detailed description of the operation process for the hot water temperature control bath will be omitted, and the following description will be made focusing on differences from the operation process for the hot water amount control bath.

  Also in the hot water temperature control bath operation process, the control unit H sets Vb or Vs as the target hot water supply amount V and sets Th, Tm or TL as the target hot water temperature T, so the target hot water supply amount V and the target As with the hot water temperature T, there are four set states of Zbh, Zsh, Zsm, and ZsL as shown in FIG. When the hot water temperature control bath operation process is executed to maintain the bathroom temperature Tr at the target temperature Tt, the set value of the target hot water temperature T is changed in the hot water temperature control bath operation process as described above. Since the process for adjusting the amount of heat applied to the bathroom is performed in preference to the process for adjusting the amount of heat applied to the bathroom 1 by changing the set value of the target hot water supply amount V, the target hot water supply amount V and the target hot water The set value of the temperature T changes as indicated by a black arrow in FIG.

  That is, the control unit H changes the set state of the target hot water supply amount V and the target hot water temperature T among the states Zbh, Zbm, and ZbL until the temperature adjustment lower limit flag F2 is changed to the on state (FIG. 9). When the temperature adjustment lower limit flag F2 is changed to the on state, the target hot water is supplied until the amount adjustment lower limit flag F1 is changed to the on state. The setting state of the amount V and the target hot water temperature T is a spray amount control state in which the state changes between the state ZbL and the state ZsL (change indicated by a black arrow in FIG. 9: ZbL⇔ZsL). Then, when the amount adjustment lower limit flag F1 is changed to the ON state, the set values of the target hot water supply amount V and the target hot water temperature T are maintained in the state ZsL until the mist operation is stopped.

  Note that, similarly to the warm water amount control bath operation process, the control unit H is in the strong heating operation mode M2 in any of the above-described four setting states in the warm water temperature control bath operation process. Although the operation is performed concurrently, when the set state is the state ZsL, when the amount of heat applied to the bathroom 1 is excessive, the heating operation mode M is switched from the strong heating operation mode M2 to the weak heating operation mode M3. Therefore, the weak heating operation is performed in parallel.

  Since the control part H performs the process shown in the flowchart of FIG. 8 in the operation process for the hot water temperature control bath, the control part H is sprayed from the mist ejection part 5 in order to maintain the temperature Tr of the bathroom 1 at the target temperature Tt. The hot water is controlled by changing the temperature of the hot water to be sprayed by changing the temperature of the hot water sprayed by the hot water. If the amount of heat applied to the bathroom 1 is excessive even if the temperature of the hot water sprayed from the mist spraying unit 5 is the lower limit of the temperature adjustment range when the process is being executed, the control state is the spray amount adjustment. It is in a state and is configured to adjust the amount of hot water. And when the control part H is adjusting the amount of heat given to the bathroom 1 by the spray temperature control state, even if the temperature of the hot water sprayed from the mist ejection part is the lower limit of the temperature adjustment range, it is given to the bathroom 1 When adjusting the amount of hot water because the amount of heat is excessive, if the amount of heat given to the bathroom 1 is excessive even if the amount of hot water is made the lower limit of the amount adjustment range, the hot air device causes the bathroom 1 It is comprised so that the calorie | heat amount provided to may be adjusted.

  When the start-up operation process is completed and the hot water amount control bath operation process or the hot water temperature control bath operation process is executed, the heating operation mode M is changed from the speed heating operation mode M1 to the strong heating operation mode M2, and the target When the setting state of the hot water supply amount V and the target hot water temperature T is the state ZsL, that is, when the target hot water supply amount V is set to Vs and the target hot water temperature T is set to TL, it is added to the bathroom 1. When the amount of heat generated is excessive, the heating operation mode M is changed from the strong heating operation mode M2 to the weak heating operation mode M3, so that the control unit H is given to the bathroom 1 by the hot air device in the start-up operation process. The operation of the hot air device is controlled so that the amount of heat generated becomes a high amount of heat applied for startup, and in the bath operation process, the amount of heat applied to the bathroom 1 by the hot air device becomes the amount of heat for hot water spraying. in front It is comprised so that the action | operation of a warm air apparatus may be controlled, and also, when the control part H is adjusting the calorie | heat amount given to the bathroom 1 by the spraying temperature control state in the operation process for baths, a mist ejection part Even if the temperature of the hot water sprayed from 5 is the lower limit of the temperature adjustment range, the amount of heat given to the bathroom 1 is excessive, so when adjusting the spray amount of hot water, the spray amount is the lower limit of the amount adjustment range. However, if the amount of heat applied to the bathroom 1 is excessive, the amount of heat applied to the bathroom 1 is adjusted by the hot air device, and the amount of heat applied to the bathroom 1 is adjusted by the spray amount control state. When the temperature of the hot water is adjusted because the amount of heat given to the bathroom 1 is excessive even if the amount of hot water sprayed from the mist ejecting portion 5 is the lower limit of the amount adjustment range, the temperature of the hot water is The lower limit of the temperature adjustment range When the amount of heat applied to the bathroom 1 even if it is too large, and is configured to adjust the amount of heat applied to the bathroom 1 by the hot air device.
