Description

  The present invention relates to a mist sauna apparatus that combines a shower type mist sauna apparatus and a mist sauna apparatus that ejects fine water droplets.

  Conventionally, there is a home mist sauna device for easily using a sauna even at home. There are two types of mist sauna devices.

  The first one is a shower that can receive the same effect as a sauna for bathed users by receiving hot water distribution from a water heater, etc., and spraying the heated hot water directly into the bathroom in a mist form This was a type of mist sauna device (see Patent Document 1).

The second one does not use heated hot water, but receives cold water from city water, finely pulverizes the distributed cold water, and ejects fine water droplets into the bathroom along with the heated hot air It was a mist sauna apparatus which can obtain the same effect as a sauna for the user who took a bath by making (refer patent document 2).

  However, each of the above-described sauna devices has a problem.

  The shower-type mist sauna device can exert the heating effect of the bathroom by hot water, but the particles to be ejected are larger, so that the relaxation effect can be used in the mist sauna environment and the newspaper cannot be read.

  In addition, the type of sauna device that ejects fine water droplets can make the particles to be ejected smaller, so that the relaxation effect can be exerted and the newspaper can be read in the sauna space, but the temperature in the bathroom is drastically increased. In some cases, it was difficult to raise the temperature or keep it higher.

(Embodiment 1)
FIG. 1 is a diagram showing a configuration of a sauna apparatus according to Embodiments 1 to 5 of the present invention.

  First, the configuration of the present embodiment will be described. A circulation fan 3 is provided inside a casing 2 attached to the ceiling 1 of a bathroom or the like that forms a sauna space, and a circulation air passage for circulating the air in the lower sauna room when the circulation fan 3 is driven. A heating means 4 such as a heater and mist nozzles 5 and 5a are provided in 3a.

  The mist nozzles 5 and 5a are connected to a water supply pipe 6 and receive a hot water distribution of about 50 ° C. and a cold water having a room temperature of about 20-30 ° C. from a hot water supply device 17. The operation of the water supply valve 7 ejects mist-like mist into the circulation air passage 3a, and the operation of the water supply valve 7a ejects mist-like mist into the bathroom.

  When hot water is jetted using the mist nozzle 5a, the air blown from the shower type mist sauna device and the circulation fan 3 is heated by the heating means 4 and applied to the cold water jetted using the mist nozzle 5. The mist sauna apparatus of the type that ejects fine water droplets that generate mist is provided.

  The configuration described above is the same in Embodiments 2 to 5 described later.

  In this type of sauna apparatus, an exhaust fan 8 is provided to ventilate the sauna room, and the exhaust fan 8 is driven to form an exhaust air passage 8a. Exhausted and ventilated.

  The control means 9 is installed in a cold place in the casing 2 and controls the circulation fan 3 and the heating means 4 described above.

  Further, in the vicinity of the mist nozzles 5 and 5a and upstream of the water supply valves 7 and 7a, a water temperature sensor 10 is provided as a water temperature measurement detecting means in the water supply pipe 6. As this water temperature sensor 10, for example, a sensor using a thermistor is used.

  FIG. 2 is a block diagram showing the configuration of the electrical system.

  The control means 9 is connected to the CPU 11 with the water temperature sensor 10 as an input, and is connected to a setting unit 12 for setting operation start / stop, timer operation, and the like. The output of the CPU 11 is a drive means 13 such as an electromagnetic relay, The circulation fan 3, the heating unit 4, and the water supply valves 7 and 7 a are connected to each other through 14 and 15, and the hot water supply device 17 is connected to the communication fan 16 through the communication unit 16.

  The setting unit 12 is operated by a user to select an operation mode such as a ventilation operation, a heating operation, or a sauna operation, and start / stop operation or timer operation, such as a switch or a timer time limit indicator. It is comprised from.

  In the above configuration, when the user selects the sauna operation in the setting unit 12 and presses the operation switch, the control unit 9 drives the circulation fan 3, the heating unit 4, and the water supply valves 7 and 7a, and the air in the sauna room Is circulated while heating and humidifying, making the sauna room warm and humid. The detailed operation of the control means 9 will be described with reference to FIGS. 1 and 2 and FIG.

  FIG. 3 shows a sequence showing the operation of the sauna apparatus according to the embodiment of the present invention. When the sauna apparatus of the present invention starts operation, the microcomputer as the control means 9 makes a hot water distribution request to the hot water supply device 17 using the communication means 16 regardless of the operation mode set by the user. The pipe from the hot water supply device 17 to the mist nozzle 5 has a maximum distance of about 15 m depending on the construction site, and a delay time of a temperature increase of about 3 minutes at the maximum after the water distribution request is started. During this delay time, normal temperature water accumulated in the piping is distributed to the sauna device, so the hot water heated by the hot water supply device 17 is not immediately distributed to the sauna device. Here, the predetermined time is set to 3 minutes which is the same as the delay time, and 40 ° C. is set as a threshold value. The water distribution temperature detected by the water temperature sensor 10 after the elapse of 3 minutes, which is a predetermined time, rises above the threshold of 40 ° C. when hot water of 50 ° C. is distributed from the hot water supply device 17. From the above, it is possible to detect that there is no problem in the communication means 16 from the sauna device to the hot water supply device 17 and the piping from the hot water supply device 17 to the sauna device by detecting the water distribution temperature after a predetermined time has elapsed. Thereafter, the sauna operation set by the user is performed.

  That is, when the sauna operation using cold water is set, as shown in FIG. 1, as shown in FIG. 1, the microcomputer after detecting hot water makes a request for water distribution to the hot water supply device 17. Next, in order to raise the temperature of the bathroom, even if the user changes the setting to sauna operation that uses hot water, it can be detected that hot water can be supplied in advance, so the operation will be interrupted You can use the sauna equipment with peace of mind.

  As a result, it is possible to detect that warm water is reliably distributed at the start of operation, regardless of whether the operation mode uses hot water or cold water. Can be changed.

  As described above, when the water distribution temperature is higher than the predetermined value, the hot water distribution request is correctly transmitted by the communication means from the sauna device to the hot water supply device, and the hot water is correctly supplied to the piping from the hot water supply device to the sauna device. It can be judged that water is distributed. That is, when using hot water, it shows that there is no problem as a sauna apparatus and a hot-water supply apparatus. Therefore, the microcomputer can recognize the operation check of the hot water supply device 17 at the start of operation, that is, that hot water can be used correctly.

  Also, if the water distribution temperature is lower than the predetermined value, there is a problem with the communication means from the sauna device to the hot water supply device, the hot water distribution request is not correctly transmitted, or the piping from the hot water supply device to the sauna device It can be determined that this is not done correctly or that the hot water supply device is stopped. That is, there is a problem with the sauna device and the hot water supply device when using hot water. Therefore, the microcomputer can recognize to the user that hot water is not available at the start of operation.

(Embodiment 2)
In the present embodiment, in addition to the configuration of the first embodiment, the minimum temperature and the maximum temperature among the temperatures detected by the water temperature sensor 10 as the water temperature measurement detection means while issuing a water distribution request are set in the control means 9. It is characterized in that the microcomputer performs processing to compare. The same constituent elements as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  The operation will be described below.

  First, the water distribution temperature is higher than a predetermined value. As described in the first embodiment, it can be easily confirmed that hot water is supplied before using the sauna apparatus. Next, the water distribution temperature is below the threshold value. Hot water and cold water are distributed from the hot water supply device 17 to the sauna device through a pipe, and it is considered that the temperature distribution is uneven in the process. For example, if the hot water supply device 17 is outdoors, the water temperature in the piping near the sauna device installed in the room is different from that in the piping near the hot water supply device 17. Therefore, the fact that water distribution is performed also changes the water distribution temperature detected by the water temperature sensor 10. Therefore, the microcomputer continuously compares the water distribution temperature within a predetermined time with the minimum temperature and the maximum temperature. If there is a difference of a predetermined temperature, for example, 2 ° C. or more even once within a predetermined time, it can be determined that water is moving inside the pipe. That is, although hot water is not distributed correctly, it can be recognized that cold water can be used.

  Third, the water distribution temperature is below the threshold value, and there is no difference between the maximum temperature and the minimum temperature by a predetermined temperature, for example, 2 ° C. or more. As described above, when hot water or cold water is distributed in the pipe, it is expected that there is a change in the distribution temperature. If piping is not connected and hot water or cold water is not distributed from the hot water supply device to the sauna device, hot water or cold water will flow through the piping even if the microcomputer makes a distribution request using communication means. There is no. Therefore, when there is no change of 2 ° C. or more, it is determined that not only hot water but also cold water does not flow in the pipe. That is, it can be recognized that neither hot water nor cold water can be used because the pipes are not properly connected.

  Then, after confirming the operation of the hot water supply device 17, that is, confirming that the hot water supply device 17 can operate correctly, the sauna device is operated.

(Embodiment 3)
In the present embodiment, processing for setting a threshold according to the situation is performed.

  First, the user can set the first threshold. Even in the actual usage situation, even if the same operation is performed, the temperature change and the rise time are expected to vary depending on the installation environment. The causes of variation include, for example, pipes used by contractors and their heat insulating materials, such as those affected by outside temperatures such as seasonal changes and temperature differences between installation areas, pipe lengths, pipe work conditions, etc. And effects of construction methods.

  Considering the installation environment in advance, determine the range of water distribution temperature, threshold value, predetermined time, etc. described above.For example, when installing with a short pipe length in a warm area, and long pipe length in a cold area When both are installed within the range in which installation is possible, the temperature change and rise time vary.

  Therefore, the first threshold value of the water distribution temperature is set so as to be set within the range of, for example, ± 5 ° C. from 40 ° C. described above. In the installation environment, if it is not possible to expect a quick start of operation, it can be determined that hot water can be used before the predetermined time has elapsed by lowering the threshold temperature, so the time until the start of micromist sauna operation using cold water can be determined. Can be shortened. On the other hand, when the installation environment has a margin and can start up quickly, for example, when installed in a warm climate in summer, the water distribution temperature itself in the pipe may exceed the threshold. As a result, before the hot water from the hot water supply device 17 arrives, there is a possibility that the water staying in the pipe and heated by the outside air temperature flows into the sauna device and is erroneously determined to be supplied with the hot water. is there. Therefore, when it is desired to make a reliable determination in such an installation environment, the threshold value can be increased.

  Second, a case where the user can set the second threshold in addition to the first threshold will be described. For example, immediately after driving the circulation fan 3 and the heating means 4 for a long time to heat the bathroom, the water distribution temperature in the pipe near the mist nozzle 5 has risen, and when the water distribution request is started, Distribution temperature may already exceed 40 ° C. In such a case, the determination is made based on the second threshold in addition to the first threshold.

  First, if it exceeds the first threshold of 40 ° C. after a predetermined time, it is considered that there is no problem in the distribution of hot water, but it has already risen close to the first threshold of 40 ° C. immediately after the water distribution request. In such a case, it cannot be determined that the increase in the water distribution temperature has necessarily increased due to the distribution of the hot water from the hot water supply device 17. Therefore, by setting the second threshold value corresponding to the temperature immediately after the water distribution request, the temperature rises clearly after the water is distributed compared to before the hot water from the hot water supply device 17 is distributed. It can be determined that there was. That is, when the temperature detected by the water temperature sensor 10 immediately after the request for distributing hot water is lower than, for example, 35 ° C. as the second threshold, exceeds the second threshold after a predetermined time, and further exceeds the first threshold Can confirm the operation of the hot water supply device 17 without being affected immediately after the heating operation, that is, the hot water supply device 17 operates correctly and can distribute hot water.

  Third, a configuration for setting the first threshold value and the second threshold value during the operation of the actual mist sauna apparatus will be described. The microcomputer stores the threshold value after a predetermined time has elapsed since the request for hot water distribution is made every time operation using hot water is performed, and this measured threshold value is performed the next time operation using hot water is performed. Is used as the first threshold. The determination method using the first threshold is as described above. By performing this process, it is possible to set a threshold value for correctly determining whether the hot water is distributed without the user or the installer being aware of the variation in the rising time of the hot water due to the installation environment. When the microcomputer determines that the first threshold is 40 ° C. during operation, the second threshold is automatically set to 35 ° C., which is 5 ° C. lower than the first threshold. As a result, using the method using the first threshold value and the second threshold value described above, it is possible to more accurately determine that the request for hot water distribution has been made correctly, in accordance with the installation environment. .

  Then, after confirming the operation of the hot water supply device 17, that is, confirming that the hot water supply device 17 can operate correctly, the sauna device is operated.

(Embodiment 4)
In this embodiment, a configuration in which two predetermined times are prepared according to the situation will be described. First, the user can set the first predetermined time. As mentioned above, when the installation environment varies, the rise time of hot water is expected to vary, but even after a predetermined time has elapsed, it is detected by a water temperature sensor in warm and cold areas. There may be differences in the water temperature that is used. For example, in a warm area, the pipe itself may rise to about 30 ° C. to 40 ° C. in the summer, and is absorbed by the pipe compared to a case where the temperature drops to near 0 ° C. in the winter in a cold area. The heat of hot water is not so hot. As a result, the warm water rise time is earlier in the warmer summer than in the colder winter. Therefore, by changing the first predetermined time, a more suitable time can be set depending on the installation environment or the season to be used.

  Secondly, the second predetermined time can be set in addition to the first predetermined time. As an example, the first predetermined time is 3 minutes and the second predetermined time is 4 minutes. As mentioned above, the rise time of hot water is expected to vary depending on the installation environment, but in regions where there is a large temperature difference between winter and summer, if the first predetermined time is set according to the summer, It is conceivable that the water temperature detected by the water temperature sensor does not reach the threshold value during one predetermined time. On the contrary, if the first predetermined time is set in accordance with the winter season, the threshold value is determined after a predetermined time that is too long in the summer, which is disadvantageous for quick start-up of driving. Therefore, the water temperature detected after the first predetermined time has been compared with the threshold value, and if the water temperature has not reached, the comparison with the threshold value is performed again at the second predetermined time. By performing such processing, even in an installation environment where there is a large temperature difference between summer and winter, it is possible to make a correct determination by configuring the first predetermined time and the second predetermined time. .

  Third, each predetermined time can be discriminated by a microcomputer, and it can be judged whether the hot water distribution request is made correctly. Each time the microcomputer is operated using warm water, it memorizes the time from when a hot water distribution request is made until the threshold value is exceeded. It is used as a predetermined time. The determination method using the first predetermined time is as described above. By performing this process, it becomes possible for the user or the installer to set a predetermined time for correctly determining whether the hot water is distributed without being aware of variations in the rising time of the hot water due to the installation environment. . When the microcomputer determines that the first predetermined time is 3 minutes during operation, the second predetermined time is automatically set to 4 minutes, which is one minute higher than the first predetermined time. As a result, using the method using the first predetermined time and the second predetermined time described above, it is possible to more accurately determine that the hot water has been properly distributed in the installation environment. Become.

  As described above, the operation of the hot water supply device 17, that is, the sauna device is operated after confirming that the hot water supply device 17 can operate correctly.

(Embodiment 5)
FIG. 4 is a block diagram showing the configuration of the electrical system of the fifth embodiment.

  In the present embodiment, a process of determining a predetermined time or a threshold value is performed during a test run.

  First, a method for discriminating a predetermined time during a test run will be described. The trial operation described in the present embodiment refers to work for confirming that the sauna device operates correctly when the installer installs the sauna device at the installation site. Therefore, it is assumed that the trial operation is performed first after the power is turned on immediately after the construction work is completed. The trial operation is a mode in which the sauna apparatus is operated by using an operation method that is operated separately from an operation mode operated by a normal user and is known only to a contractor.

  When performing operation using the sauna device during the trial operation, the contractor requests the hot water supply to the hot water supply device 17 using the communication means, and receives the hot water distribution through the pipe, as in actual use. . At this time, the time until the water temperature by the water temperature sensor 10 exceeds the threshold value is measured and stored in a storage device 18, for example, an EEPROM installed near the microcomputer. When the installer completes the trial run, the EEPROM stores a predetermined time.

  When the user actually operates and a hot water distribution request is made, the microcomputer reads the predetermined time described above from the EEPROM, and performs a process of comparing the water temperature detected by the water temperature sensor 10 with a threshold value after the predetermined time has elapsed. .

  By performing the above processing, even if there is a difference in the rise time of the hot water due to the difference in the installation environment, the predetermined time can be determined at the stage immediately after the construction before the user starts using the test operation. .

  The predetermined time stored in the EEPROM may be used as the first predetermined time described above, and a time that is one minute longer than the first predetermined time may be used as the second predetermined time.

  When a threshold value is used instead of the predetermined time, it is possible to make a determination using the same method by storing the threshold value in the EEPROM at the time of trial operation by the method shown in the third embodiment. Furthermore, the threshold value stored in the EEPROM may be used as the first threshold value, and a temperature 5 ° C. below the first threshold value may be used as the second threshold value.

  Secondly, in the case where the process for determining the predetermined time or the threshold value is performed during the above-described test operation, a process is performed in which the process does not shift to a normal operation when the test operation is not completed correctly.

  Here, two situations can be considered that the trial run is not correctly completed.

  First, it is conceivable that the predetermined time is judged at the time of trial operation and stored in the EEPROM. This is a case where the water temperature detected by the water temperature sensor is shifted to the normal operation mode without rising to the threshold during the trial operation time. As described above, since the microcomputer stores the time until the threshold is exceeded in the EEPROM as a predetermined time, the transition to the normal operation mode without the water temperature reaching the threshold does not store the predetermined time in the EEPROM. It turns out that. Therefore, if the user starts operation without the test operation being correctly completed due to an erroneous operation of the contractor's test operation, the predetermined time is not stored when the microcomputer reads the predetermined time from the EEPROM. Judge and do not drive.

  Next, it is conceivable that the threshold value is judged during trial operation and stored in the EEPROM. This is a case where the water temperature detected by the water temperature sensor does not rise within a predetermined time during the trial operation time, and shifts to the normal operation mode. As described above, since the microcomputer stores the water temperature at the predetermined time as a threshold value in the EEPROM, the transition to the normal operation mode without the water temperature reaching the threshold value within the predetermined time means that the threshold value is stored in the EEPROM. It will not be. Therefore, if the user starts operation without the test operation being correctly completed due to an erroneous operation of the contractor's test operation, it is determined that the threshold value is not stored when the microcomputer reads the threshold value from the EEPROM. Do not drive.
