Description

  The present invention relates to a sauna device that heats and humidifies a bathroom and promotes sweating by a user present in the bathroom.

  The sauna device as described above has the effect of stimulating sweating to users in the bathroom by heating and humidifying the bathroom in the home, etc., and enhancing the metabolism by the sweating and discharging waste products together with the sweat. Let us improve beauty and health.

In a conventional sauna apparatus, heat water is circulated between hot water heaters and heaters to heat the air taken from the bathroom, and the air heated by the heat exchanger is blown into the bathroom as hot air. There are provided hot air jetting means and mist jetting means for jetting hot water supplied from a hot water heater into the bathroom as mist (see, for example, Patent Document 1).
And the refinement | miniaturization of the mist ejected in a bathroom is calculated | required in order to improve comfort etc. Therefore, as another conventional sauna apparatus, a spray nozzle that sprays mist is provided in a heat exchanger that heats the air taken from the bathroom, and the mist is sprayed on the heat exchanger to make the mist finer. There is one in which warm air is blown into the bathroom (for example, see Patent Document 2).

JP 2001-276170 A JP-A-8-103480

In the sauna device described in Patent Document 1, in addition to the warm air blown into the bathroom, the temperature in the bathroom is raised by the mist blown into the bathroom. Therefore, in order to raise the temperature in the bathroom with mist, a large amount of water and energy are required, and there is a possibility that the bathroom cannot be efficiently heated. Further, since the mist is simply ejected into the bathroom by the mist ejecting means, it is difficult to make the mist finer.
In the sauna apparatus of the said patent document 2, the refinement | miniaturization of the mist sprayed in a bathroom can be achieved by spraying a mist on a heat exchanger. However, part of the mist sprayed on the heat exchanger is condensed to water before being blown into the bathroom, and there is a possibility that the bathroom cannot be efficiently heated and humidified.

  This invention is made paying attention to this point, and the objective is to provide the sauna apparatus which can heat and humidify a bathroom efficiently, aiming at refinement | miniaturization of the mist ejected in a bathroom.

In order to achieve this object, the first characteristic configuration of the sauna apparatus according to the present invention is a sauna apparatus that heats and humidifies a bathroom and promotes sweating by a user present in the bathroom.
Generated by mixing water with the pressurizing means for pressurizing water, the steam generating means for heating the water pressurized by the pressurizing means to generate water vapor, and the water vapor generated by the water vapor generating means Nozzle means for ejecting the mist to be discharged into the bathroom.

The water vapor generated by the water vapor generating means is mixed with water by the nozzle means to generate mist and ejected into the bathroom. Therefore, the inside of the bathroom can be heated and humidified with mist generated using water vapor, and the bathroom can be efficiently heated and humidified.
In the nozzle means, water can be crushed by causing water vapor to collide with water to generate a well-dispersed mist, and the generated mist can be jetted into the bathroom as it is. Therefore, since the heat capacity is large, the heat can be used effectively, and the mist can be ejected into the bathroom while suppressing the condensation of the mist. Further, since the water vapor colliding with water is a relatively high-pressure water vapor generated from the water pressurized by the pressurizing means, the pulverization force when pulverizing the water can be increased, and the mist can be miniaturized. Can do.
From the above, it has been possible to provide a sauna apparatus that can efficiently heat and humidify the bathroom while miniaturizing the mist to be ejected into the bathroom.

  A second characteristic configuration of the sauna apparatus according to the present invention is a mist that is obtained by jetting water vapor into the bathroom without being mixed with water by the nozzle means, and by mixing water vapor with water by the nozzle means. Is provided with an ejection state switching means that can be switched to a mist ejection state for ejecting water into the bathroom.

  When the ejection state switching means switches to the mist ejection state, the bathroom can be heated and humidified with mist generated by mixing water vapor and water. When the ejection state switching means switches to the water vapor ejection state, the bathroom can be heated and humidified with water vapor. Therefore, according to the preference of the user present in the bathroom, by switching the ejection state switching means between the mist ejection state and the water vapor ejection state, the bathroom can be heated and humidified in a state according to the user's preference, User comfort can be improved.

  A third characteristic configuration of the sauna apparatus according to the present invention is a water vapor pressure adjusting means for adjusting a pressure of water vapor mixed with water so as to change a particle size of mist generated by mixing water vapor with water by the nozzle means. At least one of water vapor amount adjusting means for adjusting the amount of water vapor mixed with water and water amount adjusting means for adjusting the amount of water mixed with water vapor is provided.

When the water vapor pressure adjusting means increases the pressure of the water vapor, the pulverization force when pulverizing water with water vapor increases, the particle size of the mist can be reduced, and conversely, when the water vapor pressure adjusting means decreases the water vapor pressure. The pulverization force when pulverizing water with water vapor is reduced, and the mist particle size can be increased.
If the amount of water vapor mixed into the water is reduced by the water vapor amount adjusting means, it becomes difficult to pulverize the water with water vapor, and the particle size of the mist can be increased. When it is increased, it becomes easy to pulverize water with water vapor, and the mist particle size can be reduced.
When the amount of water mixed with the water vapor is reduced by the water amount adjusting means, it becomes easy to pulverize the water with water vapor, the particle size of the mist can be reduced, and conversely, when the amount of water mixed with the water vapor is increased, It becomes difficult to pulverize water with water vapor, and the mist particle size can be increased.
Thus, the particle size of the mist can be changed by providing at least one of the water vapor pressure adjusting means, the water vapor amount adjusting means, and the water amount adjusting means. Therefore, it is possible to change the particle size of the user's favorite mist by at least one of the water vapor pressure adjusting means, the water vapor amount adjusting means, and the water amount adjusting means, and the user comfort can be improved.

  4th characteristic structure of the sauna apparatus concerning this invention is comprised so that the said nozzle means may eject water vapor | steam from the water vapor | steam ejection part provided in the circumference | surroundings of the said water ejection part toward the water ejected from the water ejection part. It is in the point.

  The water ejected from the water ejection part is well pulverized and becomes mist by being sprayed with water vapor ejected from the water vapor ejection part provided over the periphery. Therefore, the water vapor accurately collides from the periphery of the water ejected from the water ejection part, and mist can be generated efficiently.

  According to a fifth characteristic configuration of the sauna apparatus according to the present invention, the steam generating means is disposed in a combustion space in which the combustion gas of the burner flows and heats water to generate steam to generate steam. A steam separation unit that separates the steam generated from the liquid, and the steam disposed in the combustion space downstream of the steam generation unit in the flow direction of the combustion gas and separated by the steam separation unit. It is in the point comprised with the boiler provided with the overheating part which overheats and supplies to the said nozzle means.

The water vapor generated in the steam generator is separated from the liquid in the steam separator, so that moisture such as saturated water can be removed. And since the water vapor | steam isolate | separated in the steam-water separation part is heated in a superheating part, the superheated steam which does not contain moisture, such as saturated water, can be produced | generated. If this relatively high temperature superheated steam is supplied to the nozzle means, the superheated steam can collide with water and fine mist can be generated more efficiently.
And in order to produce | generate such superheated steam, it is only necessary to provide the boiler provided with the steam generation part, the steam separation part, and the superheat part, and simplification of a structure can be achieved.

An embodiment of a sauna device according to the present invention will be described with reference to the drawings.

  The bathroom 4 is provided with a bathtub 7 and a washing place 8. The water vapor generating means 3 is disposed on the outer wall portion of the bathroom 4, and the nozzle means 5 is disposed on the inner wall portion of the bathroom 4 corresponding to the front of the washing place 8. For example, the nozzle means 5 is disposed about 1/2 of the height of the bathroom 4 and on the sleeve of the counter of the washing place 8.

As shown in FIG. 2, a first water supply path 10 that is branched and connected to a water supply path 9 that supplies tap water and supplies water W to the pressurizing pump 2 and the water vapor generating means 3, and a branch connection that is connected to the water supply path 9. A second water supply path 11 for supplying water W to the nozzle means 5 is provided.
The pressurizing pump 2 is configured to pressurize the water W supplied in the first water supply path 10 to a set pressure (for example, 0.3 [MPa]). Further, the second water supply path 11 is configured to supply water W to the nozzle means 5 by tap pressure.

The steam generation means 3 is disposed in a combustion space 13 in which the combustion gas G of the burner 12 flows, and a steam generator 14 that heats water W supplied in the first water supply path 10 to generate steam, and its steam The steam / water separator 15 for separating the water vapor generated in the generator 14 from the liquid component, and the steam / water separator 15 disposed downstream of the steam generator 14 in the flow direction of the combustion gas G in the combustion space 13. The boiler 17 is provided with a superheater 16 that superheats the water vapor separated in step 1 and supplies it to the nozzle means 5. Thus, the boiler 17 which is the water vapor generating means 3 is configured to generate superheated steam SH as water vapor and supply it to the nozzle means 5.
Incidentally, the steam generation part 14 is comprised with the heat exchanger which produces | generates water vapor | steam by heat exchange with the water W and the combustion gas G. The superheater 16 is configured by a heat exchanger that generates water vapor (superheated water vapor) SH by heat exchange between the water vapor and the combustion gas G.

The nozzle means 5 mixes the steam (superheated steam) SH generated by the boiler 17 which is the steam generation means 3 and the water W supplied by the second water supply channel 11 to generate mist M, It is composed of a two-fluid nozzle that ejects the generated mist M. And the nozzle means 5 spouts water vapor | steam (superheated steam) SH from the ring-shaped water vapor | steam ejection part 19 provided in the circumference | surroundings of the water ejection part 18 toward the water W ejected from the circular water ejection part 18. FIG. It is configured as follows.
The nozzle means 5 pulverizes the water W by jetting water vapor (superheated steam) SH from the water vapor jet part 19 toward the water W jetted from the water jet part 18 to generate mist M, The mist M which was done is spouted. And the water W is ejected from the water ejection part 18 by tap pressure etc., and the water vapor | steam (superheated water vapor | steam) SH is ejected from the perimeter of the water W, and the mist M can be produced | generated efficiently. Incidentally, the steam (superheated steam) SH ejected toward the water W ejected from the water ejecting portion 18 is not limited to the entire periphery of the water ejecting portion 18, but from a part of the periphery of the water ejecting portion 18 to the steam ejecting portion 19. Then, steam (superheated steam) SH may be ejected.

  The water W supplied through the first water supply passage 10 is pressurized by the pressurizing pump 2 and then generated into steam (superheated steam) SH by the boiler 17 which is the steam generating means 3. And the nozzle means 5 collides the water W supplied in the 2nd water supply path 11 with the water vapor | steam (superheated steam) SH produced | generated in the boiler 17, and grind | pulverizes the water W with water vapor | steam (superheated steam) SH. The mist M is generated, and the mist M is ejected into the bathroom 4. In this manner, the bathroom 4 can be efficiently heated and humidified with the mist M generated using the steam (superheated steam) SH. Further, since the steam (superheated steam) SH is relatively high-pressure steam (superheated steam) pressurized by the pressurizing pump 2, the pulverizing force when pulverizing the water W can be increased, and the mist M can be refined. Can be achieved.

  For example, assuming that the pressure of water vapor (superheated water vapor) SH is 0.3 [MPa], the amount of water vapor (superheated water vapor) SH is 80 [g / min], and the amount of water W is 100 [cc / min]. In means 5, water vapor (superheated water vapor) SH and water W are mixed. Then, the mist M having a particle size of 50 to 80 [μm] (estimated value) can be ejected into the bathroom 4.

The second water supply path 11 is provided with an intermittent valve 20 capable of intermittently supplying water W and a water amount adjusting valve 21 capable of adjusting the amount of water from the upstream side thereof.
A remote controller 22 for performing various instructions such as operation of the sauna device 1 is provided on the inner wall portion of the bathroom 4. Further, the control device 23 that controls the operation of the sauna device 1 operates the intermittent valve 20, the water amount adjusting valve 21, the pressurizing pump 2, and the water vapor generating means based on various commands from the remote controller 22. 3 is configured to control the operation of the boiler 17. Incidentally, the control device 23 pressurizes the water W to a set pressure (for example, 0.3 [MPa]) in order to supply a predetermined amount of water vapor (superheated water vapor) SH through the water vapor supply path 29. 2 is started and stopped. Further, the control device 23 controls the operation of the boiler 17 in a state where the heating amount of the burner 12 is adjusted so as to supply steam (superheated steam) SH having a constant amount and a constant pressure through the steam supply path 29. It is configured.

The remote controller 22 has a water vapor ejection state in which the water vapor (superheated water vapor) SH is ejected without being mixed with the water W by the nozzle means 5, and the water vapor (superheated water vapor) SH is mixed with the water W by the nozzle means 5 and mist An ejection state command unit 24 that can command the mist ejection state for ejecting M, and a mist particle size command unit 25 that can command the size of the particle size of the mist M ejected by the nozzle means 5 are provided. .
Incidentally, the ejection state command unit 24 can be configured to be an ON / OFF operation type switch, for example, so as to command the mist ejection state when in the ON state and to command the water vapor ejection state when in the OFF state. The mist particle size command unit 25 includes, for example, two switches, a large particle size switch for increasing the particle size of the mist M and a small particle size switch for decreasing the particle size of the mist. It can be configured to instruct to increase the particle size of the mist M every time the button is pressed and to instruct to decrease the particle size of the mist M each time the particle size reduction switch is pressed.
In addition, although not shown, the remote controller 22 is also provided with an operation command unit that commands operation start and stop of the sauna device 1 and a display unit that displays various types of information.

When the water vapor ejection state is commanded by the ejection state command unit 24, the control device 23 closes the intermittent valve 20 to stop the supply of water to the nozzle means 5, and the nozzle means 5 causes water vapor (superheated water vapor). ) The steam is blown into the bathroom 4 without being mixed with the water W.
Further, when the mist ejection state is commanded by the ejection state command unit 24, the control device 23 opens the intermittent valve 20 to supply water to the nozzle means 5, and the nozzle means 5 supplies water vapor (superheated steam). ) SH is mixed with water W to make a mist ejection state in which mist M is ejected into the bathroom 4.
As described above, the ejection state switching means 26 that can be switched between the water vapor ejection state and the mist ejection state is constituted by the control device 23 and the intermittent valve 20.

  Incidentally, when the mist ejection state is set, the mist M to be ejected into the bathroom 4 is set to the initial operation state. In this initial operation state, for example, the pressure of steam (superheated steam) SH is 0.3 [MPa], the amount of steam (superheated steam) SH is 80 [g / min], and the amount of water W is 100 [Cc / min].

  When the control device 23 is instructed to increase the particle size of the mist M by the mist particle size command unit 25, the control device 23 controls the water amount adjustment valve 21 to increase the opening amount of the water amount adjustment valve 21 by the set opening amount. By operating, the particle diameter of the mist M ejected by the nozzle means 5 is increased by the set diameter. In addition, when the control device 23 is instructed to reduce the particle size of the mist M by the mist particle size command unit 25, the water amount adjustment valve 21 is configured to reduce the opening amount of the water amount adjustment valve 21 by the set opening amount. Is operated to reduce the particle diameter of the mist M ejected by the nozzle means 5 by the set diameter.

To explain, when the opening of the water amount adjusting valve 21 is increased by the set opening, the amount of water supplied to the nozzle means 5 is increased and the amount of water mixed with the steam (superheated steam) SH is increased. The particle diameter of the mist M ejected at 5 can be increased. On the contrary, when the opening of the water amount adjusting valve 21 is reduced by the set opening, the amount of water supplied to the nozzle means 5 is reduced and the amount of water mixed with the steam (superheated steam) SH is reduced. The particle diameter of the mist M ejected at can be reduced.
Thus, in order to change the particle size of the mist M ejected by the nozzle means 5, the water amount adjusting means 27 for adjusting the amount of water mixed with the steam (superheated steam) SH is provided. The water amount adjusting means 27 is composed of a control device 23 and a water amount adjusting valve 21.

For example, the pressure of water vapor (superheated water vapor) SH is 0.3 [MPa], the amount of water vapor (superheated water vapor) SH is 80 [g / min], and the amount of water W is 100 [cc / min]. In the initial operation state, when the opening of the water amount adjusting valve 21 is increased and the amount of water W ejected is 150 [cc / min], the mist M having a particle diameter larger than 50 to 80 [μm] is supplied to the nozzle means 5. Can be ejected into the bathroom 4.
Further, from the above-described initial operation state, when the opening amount of the water amount adjusting valve 21 is reduced and the ejection amount of the water W is 50 [cc / min], a mist M having a particle diameter smaller than 50 to 80 [μm] is obtained. It can be ejected into the bathroom 4 by the nozzle means 5.
By the way, if the amount of water W ejected is 0 [cc / min], only steam SH will be ejected. Depending on the room temperature and humidity, mist with a particle size of about 0 to 10 [μm] is ejected. Will be.

  And the user 6 who exists in the bathroom 4 can select any one of a water vapor | steam ejection state and a mist ejection state by operating the ejection state instruction | command part 24 of the remote control 22. FIG. Further, the user 6 existing in the bathroom 4 can set the particle size of the mist M to a desired particle size by operating the mist particle size command unit 25 of the remote controller 22. Thus, the ejection state and the mist particle size can be changed according to the preference of the user 6, and the comfort of the user 6 can be improved.

[Second Embodiment]
This 2nd Embodiment is another embodiment of the said 1st Embodiment, and is another embodiment about the structure for changing the particle size of the mist M ejected by the nozzle means 5. FIG. Hereinafter, a configuration for changing the particle size of the mist M ejected by the nozzle means 5 will be described. Since other configurations are the same as those of the first embodiment, description thereof will be omitted.

  A steam supply passage 29 for supplying steam (superheated steam) SH from the boiler 17 to the nozzle means 5 is provided with a steam control valve 30 capable of adjusting the steam amount or the steam pressure, as shown by the dotted line in FIG. Yes. And the control apparatus 23 is comprised so that the action | operation of the water vapor regulating valve 30 may be controlled.

  When the control device 23 is instructed to increase the particle size of the mist M by the mist particle size command unit 25, the water vapor adjustment valve is configured to decrease the amount of water vapor or the water vapor pressure supplied to the nozzle means 5 by a set amount. 30 is operated, and the particle diameter of the mist M ejected by the nozzle means 5 is reduced by the set diameter. Further, when the control device 23 is instructed to reduce the particle size of the mist M by the mist particle size command unit 25, the water vapor adjustment is performed so as to increase the amount of water vapor or the water vapor pressure supplied to the nozzle means 5 by a set amount. The valve 30 is operated to increase the particle diameter of the mist M ejected by the nozzle means 5 by the set diameter.

  To explain, if the amount of water vapor or the water vapor pressure supplied to the nozzle means 5 is decreased by adjusting the opening of the water vapor adjusting valve 30, the water W becomes difficult to be crushed by the water vapor (superheated water vapor) SH. The particle diameter of the mist M ejected at can be increased. Conversely, when the amount of water vapor or the water vapor pressure supplied to the nozzle means 5 is increased by adjusting the opening of the water vapor adjusting valve 30, the water W is easily crushed with water vapor (superheated water vapor) SH. The particle diameter of the mist M ejected at can be reduced.

  Thus, the steam adjusting means 31 for adjusting the pressure of the steam (superheated steam) SH to be mixed with the water W or the amount of steam to be mixed with the water W in order to change the particle diameter of the mist M ejected by the nozzle means 5. Is provided. The water vapor adjusting unit 31 is a water vapor pressure adjusting unit or a water vapor amount adjusting unit, and includes a control device 23 and a water vapor adjusting valve 30.

In order to change the particle size, the water vapor adjusting means 31 is provided.
Thus, when the amount of water supplied to the nozzle means 5 or the pressure of the water vapor (superheated steam) SH supplied to the nozzle means 5 is changed in a state where the amount of water mixed with the water vapor (superheated steam) SH is constant, As the amount of water vapor or the water vapor pressure supplied to the nozzle means 5 is increased, the particle size of the mist M can be reduced.

Further, the particle diameter of the mist M can be changed by adjusting only one of the water amount adjusting means 27 and the water vapor adjusting means 31. For example, when the control device 23 adjusts the water amount adjusting means 27 so that the particle size of the mist M commanded by the mist particle size command unit 25 is within the water amount adjustment setting range, the particle size of the mist M is adjusted. To change. And the control apparatus 23 adjusts by the water vapor adjustment means 31 that the particle size of the mist M instruct | indicated in the mist particle size instruction | command part 25 is in the setting range for water vapor adjustment, The particle size of mist M To change.
