DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom sauna apparatus for heating a bathroom by injecting hot water.

[0002]

2. Description of the Related Art As a bathroom sauna device, for example, there is a device that raises the temperature in a bathroom by injecting hot water into the bathroom in a mist form. However, in such a device, since mist of hot water having a large particle diameter is also sprayed, these touch the body,
In addition to the problem of being physically unpleasant, there is also a problem that the hot water is used unnecessarily and resources are wasted.

For this reason, a bathroom sauna apparatus has been proposed which solves the above problem by using a fan and a heat exchange promoting member (Japanese Utility Model Laid-Open No. 6-63103). In this bathroom sauna apparatus, as shown in FIG. 17, hot water N is jetted onto a heat exchange promoting member 201 having fins attached around the pipe to form a heated atmosphere in the housing 200. The air P is drawn into the housing 200 by the fan 202, thereby heating the air P to form the heated air Q, and then blowing the heated air Q into the bathroom. The hot water N after the heat exchange is collected in a hot water receiver 203 and then discharged to a pit.

In this bathroom sauna apparatus, since the heated air Q does not contain a large mist of hot water N, the heated air Q
It has the advantage that it has a good feeling of contact with the body and can be bathed in the sauna in a comfortable state.

[0005]

However, the above-mentioned conventional bathroom sauna apparatus requires a large fan 202 for heating the air, which leads to an increase in the size and cost of the apparatus. There was a problem. In this bathroom sauna apparatus, the hot water N after heat exchange is not reused.

In view of the above, the present invention does not include a large mist of hot water in the heated air even when hot air for a sauna is formed by injecting hot water into the air in the form of a mist. It is an object of the present invention to provide a bathroom sauna apparatus that can effectively use resources by collecting hot water and that does not require a large fan for heating air.

The nozzle 20 is for injecting the hot water J into the duct 10 at high speed in the form of a mist, and one nozzle 20 is attached to each of the upstream side of the upper duct 11 and the upstream side of the lower duct 12. As shown in FIG. 3 and FIG.
A plurality of empty conical nozzles 22 are attached side by side in the longitudinal direction of FIG. As shown in FIG. 5 (a), the empty conical nozzle 22 jets hot water J as a radial mist flow J1 substantially along a conical surface, and is well known. This empty conical nozzle 22 is shown in FIG.
As shown in (b) of FIG.
1 has the advantage that the particle size of the mist can be made smaller than that of the charged conical nozzle 23, but the contact time of the mist flow J1 with the air K is shorter than that of the charged conical nozzle 23. Has disadvantages. In addition, the particle size of the mist generally decreases as the injection amount of the hot water J from one nozzle decreases.

Therefore, the nozzle 20 uses the empty conical nozzle 22 and reduces the amount of hot water J injected from one empty conical nozzle 22 by using a plurality of the empty conical nozzles. By making the mist particle diameter of the injected hot water J sufficiently small, and simultaneously injecting the hot water J from a plurality of hollow cone nozzles 22 arranged side by side,
The shape of the mist flow J1 can be approximated to the shape of the mist flow J1 of the charged conical nozzle 23, and the contact time between the mist J1 and the air K can be kept relatively long.

Here, the reason why the air K can be sucked into the duct 10 by the mist flow J1 of the hot water J jetted from the nozzle 20 at high speed is the same as that by the ejector. Kinetic energy is given to the air, and the air moves in the duct 10 to generate a negative pressure around the suction portion 121a of the duct 10. In this case, if the particle size of the mist is small, the contact area between the mist flow J1 and the air K increases, so that the energy of the mist flow J1 is sufficiently transmitted to the air K, and more air K is ducted. 1
It can be sucked within zero. In addition, if the contact time between the mist flow J1 and the air K is long, the energy of the mist flow J1 is sufficiently transmitted to the air K side, so that much air K can be sucked into the duct 10.

When the particle size of the mist is reduced and the contact area between the mist flow J1 and the air K is increased, the amount of heat transfer from the mist to the air K is also increased, and the air K is sufficiently heated accordingly. When the contact time between the mist flow J1 and the air K becomes longer, the amount of heat transfer from the mist to the air K also increases.

Next, the operation of the sauna device 5 will be described. When the electromagnetic valve 32c of the hot water supply facility 30 is opened and the pressurizing pump 32a is operated, hot water J of a predetermined temperature and a predetermined pressure passes through the hot water supply pipe 31 and the air heater 40,
Mist-like high-speed injection into the upper duct 11 of the duct 10 is performed from the first nozzle 20A. Mist flow J1 of this warm water J
Moves the air in the duct 10 toward the discharge unit 111a, so that a negative pressure is generated on the suction unit 121a side of the duct 10,
Air is sucked into the duct 10 from around the suction part 121a. For this reason, the mist of the hot water J mixes with the air sucked into the duct 10 and flows through the duct 10 while giving heat to the air.
Through the discharge part 111a of the duct 10 and the discharge opening 70 of the apron 3, it is jetted into the bathroom space W.

That is, the air K in the bathroom space W is sucked into the duct 10 through the intake opening 71 of the apron 3 and then mixed with the mist of the hot water J to become the heated air L. Thereafter, the air is jetted again into the bathroom space W to heat the interior of the bathroom space W.

After a certain period of time has elapsed after the injection of the hot water J from the first nozzle 20A, the mist of the hot water J having a large particle diameter adheres to the inner surface of the upper duct 11 and becomes the first reservoir. The collected hot water M is stored in the hot water collection reservoir S1 at 110a. Therefore, at this point, the re-pressurizing pump 5
2, the recovered hot water M is supplied to the second nozzle 20B, and the recovered hot water M is injected into the lower duct 12 at high speed from the second nozzle 20B in the form of a mist. This allows
Further air K is sucked into the duct 10 by the injection of the recovered hot water M from the second nozzle 20B, and the temperature of the recovered hot water M is sufficiently higher than the heated air L. The air K is sufficiently heated by the mist. Then, the first and second nozzles 20A,
Since the injection amount of the hot water J from the 20B is controlled and the temperature in the bathroom space W is controlled to be, for example, 40 ° C., the sauna user in the bathroom space W is warmed up while Sweating action is promoted.

Here, the air K is heated when it comes into contact with the mist, and the saturated vapor pressure rises.
Due to evaporation of the mist, an amount of water vapor corresponding to the saturated vapor pressure of the air is contained. In this case, the latent heat of vaporization of the mist is obtained by, for example, lowering the temperature of the other mist. Then, the heated air L injected into the bathroom space W mixes with the air K in the bathroom space W to produce new air K whose temperature has increased.
However, as shown in FIG. 7, since the saturated vapor pressure of the heated air L is significantly higher than that of the air K or the new air K ′, when the new air K ′ is formed, Then, dew condensation of water vapor occurs, and the new air K 'is sufficiently heated by the latent heat of evaporation of the water generated at this time. That is, the temperature of the new air K ′ is further increased by the amount of latent heat of evaporation of the condensed water from the temperature of the air obtained by simply mixing the heated air L and the air K.

On the other hand, the mist sprayed from the nozzle 20 mixes with the air in the duct 10.
A large particle passing through the center of the duct 10 and having a large particle size is removed from the inner wall of the duct 10 when moving from the horizontal portion 110 of the upper duct 11 to the inclined portion 111.
3 and adheres to the bottom surface of the inclined portion 111 and the side surface of the bent duct 13 and is removed. Therefore, of the mist ejected from the nozzle 20, most of the mist having a large particle diameter are stored in the duct 10, and those having a small particle diameter are ejected into the bathroom space W as the heated air L. . The mist attached to the inner surface and the bottom surface of the duct 10 flows down along the inner surface of the duct 10 and is collected in the first and second reservoirs 110a and 120a of the duct 10.

In this case, there is a possibility that drainage during bathing flows into the duct 10 through the discharge unit 111a and the suction unit 121a, but the first and second reservoirs 110a, 120a
a, there is a possibility that the washing water D (see FIG. 8) is not mixed with the hot water collecting reservoirs S1 and S3 for the collected hot water M that collects only the mist inside the duct 10 and the washing water D. , The mist at the end of the duct 10 is separated into drainage reservoirs S2 and S4, so that clean recovered hot water M is injected by the second nozzle 20B and clean recovered hot water M is reliably recovered. Is done.

Since the first and second horizontal guide plates 14 and 15 are provided in the discharge portion 111a and the suction portion 121a of the duct 10, as shown in FIGS. 8 (a) and 8 (b), For example, in the case where the second horizontal guide plate 15 is provided, the washing place drainage R can be prevented from being scattered inside the duct 10 when compared with the case where the second horizontal guide plate 15 is not provided. Therefore, by providing the first and second horizontal guide plates 14 and 15, the hot water collecting reservoirs S1 and S3 can be enlarged, and the amount of the collected hot water M can be increased.

The recovered hot water M in the hot water recovery reservoir S3
The collection pump 62a is transferred to the bathtub 2 by operating the collection pump 62a, and can be used for bathing. The collected hot water M in the bathtub 2 is connected to a coupler 64b with a check valve by connecting a hose or the like. After that, by operating the reuse pump 64a, it can be variously used as water for washing machines, bathroom cleaning, and garden watering. The drainage in the drainage reservoirs S2 and S4 is poured into a bathroom drainage pit, and the collected hot water M may be discharged into the bathroom drainage pit via the three-way valve 62c. May be discharged into this drainage pit.

By the way, the heated air L flowing in the duct 10 is heated by the air heater 40 in the lower duct 12, but the temperature of the hot water J also decreases accordingly.
The air heater 40 does not seem to play any role in the sauna device 5. However, in the air heater 40, when the temperature of the hot water J supplied to the first nozzle 20A decreases, the temperature of the recovered hot water M in the hot water recovery reservoir S3 discharged to the outside also decreases accordingly. Therefore, in terms of increasing the temperature of the bathroom space W, the thermal efficiency of the sauna device 5 can be increased accordingly.

Since the air K and the mist flow J1 are parallel flows flowing in the same direction, the amount of heat transferred from the mist to the air K gradually decreases. However, since the flow of the hot water J in the air heater 40 and the flow of the heated air L in the duct 10 are opposed to each other, the heated air L flows closer to (or away from) each other. The heat is efficiently heated by the air heater 40, and the thermal efficiency of the sauna device 5 can be increased accordingly.

Since the plurality of second horizontal guide plates 15 are provided in the suction portion 121a of the duct 10, the discharge opening 70 and the intake opening 71 of the waterproof floor pan 3 are located at positions close to each other. Even if the second horizontal guide plate 15 is operated, the heated air L
However, the air is not immediately sucked into the duct 10 via the intake opening 71.

As described above, in the sauna device 5, the air K is sucked into the duct 10 by utilizing the negative pressure generated by high-speed injection of hot water in a mist state in the duct 10, Since the heated air L is formed by mixing K and mist, a large fan is not required for heating the air, which reduces the size and cost of the device, and reduces the operating and maintenance costs. Can be planned.

In particular, in the sauna device 5, a nozzle 20 is provided in the upper duct 11 and the lower duct 12, and the upper duct 11 and the lower duct 12 form the hot water J and the mist flow J1 of the recovered hot water M, respectively. Therefore, sufficient air K can be sucked into the duct 10 and the sucked air K can be sufficiently heated by the mist of the hot water J and the recovered hot water M. In this case, the hot water J is injected from the first nozzle 20A on the downstream side, and the recovered hot water M having a lower temperature than the hot water J is injected from the second nozzle 20B on the upstream side. The air K is heated by the mist whose temperature is sequentially increased, and the heating of the air K is also effectively performed.

Further, in the sauna device 5, the mist of the hot water J is sprayed in the duct 10, and the mist having a large particle diameter is adhered to and removed from the inner surface of the duct 10, so that the mist is sprayed into the bathroom space W. The ratio of the mist having a large particle size in the heated air L can be reduced. For this reason, the inconvenience that the mist having a large particle diameter touches the body of the sauna user and gives an unpleasant feeling can be sufficiently solved.

In particular, in the sauna device 5, the upper duct 11 is provided in the left closed space V1 at one longitudinal end of the bathtub 2.
Since a relatively long duct 10 composed of the lower duct portion 12 and the bent duct 13 is arranged, and the duct 10 is bent halfway to change the flow direction of the heating air L, the particle size of the heating air L The large mist is sufficiently attached to the inner surface of the duct 10 and removed while moving through the duct 10. Further, the mist having a large particle size is distributed to the horizontal portions 110 and 120 of the upper duct 11 and the lower duct 12.
While moving inside, it falls by its own weight,
It adheres to the bottom of 10, 120 and is removed. In addition, the longer the duct 10, the longer the contact time between the air K and the mist, and the air K is sufficiently heated by the mist.

Further, in the sauna device 5, the first reservoir 110 for collecting the mist of the hot water J is provided in the upper duct 11.
a, and the collected hot water M in the first liquid reservoir 110a is supplied to the second nozzle 20B, so that the hot water J can be effectively used and the amount of the hot water J used can be reduced.

In the sauna device 5, the second reservoir 12 for collecting the mist of the collected hot water M is provided in the lower duct 12.
Since 0a is provided, the hot water J (recovered hot water M), which no longer contributes to the heating of the air K, can be sufficiently recovered, and the resources can be effectively used. Further, the first and second liquid reservoirs 110a and 120a are provided with a hot water recovery reservoir S.
1 and S3 and the sump S2 and S4.
Since the collected hot water in the drainage reservoirs S2 and S4 in which water may be mixed is discharged without reuse, the cleanness of the collected hot water M can also be increased.

Further, in the sauna apparatus 5, since the recovery pump 62a is provided to transfer the recovered hot water M in the hot water recovery reservoir S3 to the bathtub 2, the recovered hot water M can be used immediately as hot water for bathing. In addition, by storing the recovered hot water M in the bathtub 2, the use of the recovered hot water M can be facilitated. In particular, in the sauna device 5, a reuse pump 64a is provided so that the recovered hot water M in the bathtub 2 can be transferred to another place.
Use of the recovered hot water M can be further facilitated.

In the sauna apparatus 5, the nozzle 20
However, since a plurality of empty conical nozzles 22 are provided side by side in the longitudinal direction of the duct 10, the particle size of the mist can be reduced, and the mist flow J1
Can be brought into contact with the air K for a relatively long time. For this reason, a large negative pressure is generated in the suction portion 121a of the duct 10, so that a sufficient amount of the air K can be sucked into the duct 10, and the sucked air K can be sufficiently heated.

Further, in this sauna device 5, the duct 1
An air heater 40 is provided in the vicinity of the suction unit 121a of the air conditioner.
Since the temperature of the hot water J supplied to the nozzle 20 is lowered, the temperature of the recovered hot water M discharged to the outside can be lowered, and the thermal efficiency of the sauna device 5 can be improved accordingly. Further, since the hot water J and the heated air L are caused to flow in opposite directions by the air heater 40, and the heated air L is heated by the hot water J, the heat flow is compared to the case of the parallel flow. In addition, the thermal efficiency of the sauna device 5 can be increased.

Further, in this sauna device 5, the duct 1
Since the plurality of first and second horizontal guide plates 14 and 15 are provided in the zero discharge part 111a and the suction part 121a, the direction of the heated air L discharged from the duct 10 can be changed in the vertical direction. The air K can be sucked into the duct 10A from above and below the washing place A. Further, the first and second horizontal guide plates 14 and 15 can restrict the scattering position of the washing area drainage R entering the duct 10 from the washing area A to the vicinity of the discharge section 111a and the suction section 121a of the duct 10. The drainage reservoirs S2 and S4 in the first and second reservoirs 110a and 120a can be made smaller, and the amount of the recovered hot water M can be increased accordingly.

In the sauna device 5, since the nozzle 20 serving as a sound oscillating source is housed in the duct 10,
The noise in the bathroom space W can be suppressed,
Since the vibration damping material is attached to the outer surface of the duct 10 and the sound absorbing material is attached to the outer surface of the bathtub 2 and the like, the noise in the bathroom space W can be suppressed accordingly.

Further, in the sauna device 5, since the sauna device 5 is installed in the closed space V below the bathtub 2, the installation of the sauna device 5 does not make the bathroom space W narrow, and the sauna device 5 Suction unit 121 of the duct 10
a can be arranged on the lower side of the bathroom, and accordingly, the interior of the bathroom space W can be efficiently heated. Also, the appearance in the bathroom is not impaired.

In the sauna device 5, the duct 10
Is disposed below the left closed space V1 at one end of the bathtub 2 and the space above the duct 10 is greatly left.

2 may be operated during the operation of the sauna, and this may be used as an aid for sucking the air K into the duct 10.

Further, as shown in FIG. 10, the duct 10 to which the nozzle 20 is attached is also installed in the right closed space V2 at the other end in the longitudinal direction of the bathtub 2, and the heated air L is supplied from both left and right sides of the apron 3. May be jetted into the bathroom space W. In this case, the temperature of the recovered hot water M in the hot water recovery reservoir S3 of the duct 10 is also sufficiently high. Therefore, as shown in FIG. The pressure may be supplied to the first nozzle 20A in the other duct 10 by using the pressure pump 73 to improve the thermal efficiency of the sauna device 5 and effectively use the recovered hot water M. In this case, the recovered hot water M in the hot water recovery reservoir S3 of the other duct 10 is transferred to the bathtub 2 using the recovery pump 62a.

As shown in FIG. 12, the air heater 40 spirally winds a pipe through which hot water J passes, and passes heated air L inside and outside the pipe. Is also good. Needless to say, in this case, the pipe may be made to approach the inner wall of the duct 10, and the heated air L may be passed only inside the air heater 40.

Further, if the supply pressure of the hot water J is sufficient in the hot water supply equipment 30, a plurality of constant flow valves 32g are provided in parallel as shown in FIG. Thus, the flow rate of the hot water J supplied to the nozzle 20 may be controlled, or a flow rate control valve 32h may be provided as shown in FIG. Of course, constant flow valve 3

It is sufficient to push the duct 10 into the space V1 and to take out the duct 10 from the left closed space V1 while sliding the duct 10 on the guide rail 74 and pulling it out toward the washing place 1b side of the waterproof floor pan 1. . Therefore, the guide rail 74 can facilitate installation and removal of the duct 10 and the like.

In particular, this guide rail 74 is most suitable when the duct 10 and the like are installed in a bathroom unit (for an apartment) where the step between the bathtub installation section 1a and the washing section 1b of the waterproof floor pan 1 is small. In this case, the duct 10 can be installed close to the bottom side of the waterproof floor pan 1, and a sufficient empty space can be formed above the duct 10 in the left closed space V1.

The pump is properly used by the reverse rotation. Also, the re-pressurizing pump 52 may operate another pump by one motor.

In the sauna device 5, the second nozzle 20 B is connected to the horizontal portion 120 and the inclined portion 121 of the lower duct 12.
However, it may be installed on the slope portion 121 side to change the flow direction of the heated air L. Also, the flow of the heated air L is not directed from the lower duct 12 side to the upper duct 11 side, but is directed to the upper duct 1 side.
You may make it face from the 1 side to the lower duct 12 side.

Further, in this sauna apparatus 5, the first and second nozzles 20A and 20B are formed from a plurality of empty cone nozzles 22, but the first nozzle 20A is formed by one empty cone nozzle 2A.
2 to reduce the flow on the center side of the mist J1,
The mist amount of the warm water J flowing into the drain reservoir S2 of the first reservoir 110a may be reduced. Also, the second nozzle 20B
