Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the structure of a box-type sauna bath.

[Summary of the idea]

In the present invention, the upper part of the sauna box is configured in a substantially sealed state, a ventilation hole is provided in the lower part of the sauna box, a fan is provided in the ventilation hole for discharging the air inside the sauna box, and the humidification from the humidifying means is provided. By installing an outlet near the ceiling of the sauna box that blows out the humidified air, it is possible to create a negative pressure inside the sauna box with respect to the outside air, and also to prevent the humidified air from affecting other air flows. It is possible to move the humidified air from the upper part of the sauna box downward without being absorbed, and for this reason, the humidified air can be evenly distributed from the upper part to the lower part of the sauna box, and This is designed to reduce the temperature difference between the upper and lower parts of the sauna box.

[Conventional technology]

In a sauna bath, the temperature of the layer of air that surrounds the body is important, and the temperature of other parts, such as the ceiling and the area under the seat, can be said to have almost no relation to the bathing effect. It is also preferable that the head is cold and the feet are warm, especially the temperature applied to the head should be 80°C.
The limit is around ℃. Furthermore, humidity is an important condition for sauna baths. In other words, taking a high-temperature sauna puts too much stress on the heart and poses a safety problem, so in such cases, we use a medium temperature and compensate for this by increasing the humidity. .

In conventional box-type sauna baths, various measures have been taken to ventilate the inside of the box in order to satisfy the above-mentioned conditions. The following three types of conventional ventilation structures are known.

(1) A ventilation window installed in the ceiling of a box that can be opened and closed freely.

(2) A ventilation window is installed in the ceiling of the box, and this ventilation window is equipped with a fan for air intake.

(3) The inside of the box is kept in a nearly sealed state, and a duct is provided in the box in the vertical direction, and ventilation holes communicating with the inside of the box are provided in the upper and lower parts of the duct, and both the upper and lower ventilation holes or A fan is installed on one side to force air from the upper part of the box to the lower part through a duct to circulate the air.

[Problem that the invention attempts to solve]

Methods (2) and (3) described above are methods in which the temperature inside the box is made uniform by forcibly circulating and convecting the air inside the box by using a fan. However, in reality, even if the air inside the box rises to a predetermined temperature and is maintained at that temperature, the moving air comes into direct contact with the skin when the fan is rotating, causing the skin to feel cold. Sometimes I put it away.

In addition, if the ventilation window is open in method (1) above, or if the fan is stopped in method (2) above, the ventilation window at the top acts as an exhaust hole, so the inside of the box The warm air escapes. For this reason, the air at the top is cooled, and as a result of this cooled air coming down, the bottom
In other words, the temperature at your feet will drop.

For the reasons mentioned above, in conventional box-type sauna baths, there is a large temperature difference between the upper and lower parts of the box, and the temperature in the upper part is particularly higher than that in the lower part. For example, when the temperature is 75℃ at the top, it is 35℃ at the bottom.
There were cases where the temperature difference was over 40℃. This is the opposite of the condition of having a cold head and warm feet, and is not desirable for a sauna bath.

Furthermore, in conventional box-type sauna baths, the air pressure inside the box is approximately the same as the outside air, so the temperature inside the box sometimes drops due to slight air leaks. Furthermore, a large-capacity fan was required to circulate and convect the air inside the box.

[Means for solving problems]

In the present invention, the upper part of the sauna box is configured in a substantially sealed state, a ventilation hole is provided in the lower part of the sauna box, a fan is provided in the ventilation hole for discharging the air inside the sauna box, and the humidification from the humidifying means is provided. This sauna bath is characterized in that a spout for spewing out air is provided near the ceiling of the sauna box.

[Effect]

In the present invention, a ventilation hole is provided in the lower part, and a fan for discharging the air inside the sauna box is provided in the ventilation hole, so that the inside of the sauna box has a negative pressure with respect to the outside air.

Furthermore, since the upper part of the sauna box is constructed in a substantially sealed state, and the outlet for ejecting humidified air from the humidifier is provided near the ceiling of the sauna box, the humidified air is not affected by other air currents. It is possible to move the humidified air from the upper part of the sauna box downward without causing any turbulence, and for this reason, the humidified air can be almost evenly distributed from the upper part to the lower part of the sauna box, and The temperature difference between the upper and lower parts of the sauna box can be reduced.

〔Example〕

1 to 3, a sauna box (hereinafter simply referred to as the box) 1 is separably separated into a front portion 1a and a rear portion 1b, both of which are integrally connected by a fixing band 2. The front part 1a and the rear part 1b are constructed so that the box 1 can be constructed by assembling them in a one-touch manner. A seat 3 is provided on the rear surface of the box 1 so that a bather 4 can sit on it, and heaters 5 such as ceramic heaters are covered with a protective net 6 at three locations on the rear surface and on the left and right sides. It is provided.

Further, a door 7 is provided on the front surface so as to be openable and closable, and an operation panel 8 and a fragrance storage section 9 are also provided. The operation panel 8 has air holes 1 at 4 locations on the top and bottom.
0 is provided, and various operation knobs 11 such as a power switch, a temperature adjustment knob, etc. are appropriately arranged. The fragrance storage section 9 is provided with an opening/closing lid 13 with an air hole 12a on the front side, an air hole 12b on the rear side, and a fragrance box 14 in which fragrances are stored. .

The door 7 is provided with an opening/closing window 15 for air adjustment. This opening/closing window 15 has a plurality of long holes 16 arranged in a grid pattern on the door body side, and a sliding plate 18 with a plurality of long holes 17 arranged in a grid pattern so as to be slidable in the horizontal direction. It consists of 4 bathers.
A knob provided on the sliding plate 18 can be operated by hand. and the long holes 16 and 17
When the opening/closing window 15 matches, the opening/closing window 15 is opened and the elongated hole 16 is opened.
If 17 and 17 are out of alignment, it will be closed. In this embodiment, the opening/closing window 15 is arranged substantially in front of the face of the bather 4 sitting on the stool 3.

A control box 20 provided with an air hole 19 is provided inside the operation panel 8, and a protective cover 21 is provided to cover the control box 20 and the fragrance storage section 9. This protective cover 2
1 is provided with an air hole 22, and the air hole 1 is provided with an air hole 22.
0, 19, 12a, and 12b.

An exhaust hole 23 is provided below the seat 3 on the bottom of the box 1, and an exhaust fan 24 is attached to the exhaust hole 23. This fan 24
is a protective cover 2 with many holes 25 on both sides.
6.

Further, an ultrasonic humidifier 27 is provided outside the ceiling plate of the box 1. A spray pipe 28 is led out from the humidifier 27, and its opening 28a is arranged downward from the ceiling of the box 1 into the box. Also, humidifier 27 and fragrance box 1
4 is connected to the humidifier 2 by a suitable means such as a pipe (not shown), and the fragrance in the fragrance box 14 is connected to the humidifier 2.
7. Incidentally, as the above-mentioned fragrance, for example, those having the fragrance of plants such as eucalyptus and pine needles are used.

Since the sauna box 1 according to the present invention is constructed as described above, when the door 7 and the opening/closing window 15 are closed, the upper part of the inside of the box 1 is substantially sealed. That is, since only a small amount of air enters and exits through the air holes 10 and 12a on the front surface of the box, the upper part is almost sealed. If the heater 5 is heated in this state, the temperature of the air inside the box 1 will rise. Also, the air inside the box 1 undergoes convection and the temperature at the top becomes higher than at the bottom.

Then, when taking a bath, at an appropriate time,
At the same time, the humidifier 27 is operated to spray mist water from the opening 28a of the spray pipe 28 for humidification. In this case, since there is no other airflow inside box 1, the humidified warm air in the upper part of box 1 is smoothly moved downward by fan 24 without being affected by the other airflow. . For this reason, the humidified warm air is almost evenly distributed from the top to the bottom within Box 1 without causing convection or turbulence, so the inside of Box 1 can be almost uniformly humidified. Moreover, it is possible to effectively warm the feet of the bather. Therefore, the temperature difference between the upper and lower parts can be made smaller than in the past. According to experiments, when the temperature of the upper part is 75°C, the temperature of the lower part can be increased to about 60°C, and the temperature difference between the upper part and the lower part can be reduced to 40°C.
It was confirmed that it is possible to reduce the temperature from ℃ to around 15℃ at once.

Also, if you open the opening/closing window 15 while taking a bath, cold air from outside will flow into the box 1 through this opening/closing window 15.
be introduced within. Since this cold air hits the vicinity of the head of the bather 4, the head can be appropriately cooled and a state of cold head and warm feet can be achieved.

In addition, when spraying dew ice with the humidifier 27,
By spraying fragrances together, the scent can be dispersed almost evenly.

When the fan 24 is being driven, the inside of the box 1 is in a substantially hermetically sealed state, so that it is under negative pressure with respect to the outside air. Therefore, air leakage from the box 1 is eliminated, and the warm air inside the box 1 can be effectively stored. In addition, since the fan 24 is used simply to lower the upper air,
It is particularly economical since there is no need to use a large-capacity fan.

Note that various modifications can be made to this embodiment. For example, the opening/closing window 15 can be provided not only in front of the face but also at least at a position above the position of the exhaust hole 23 to cool any desired area as required. The exhaust hole 23 may be provided not only at the bottom of the box 1 but also below the front, rear, left and right side walls.
Alternatively, the fragrance box 14 may be provided inside the humidifier 27.

[Effect of idea]

As described above, in the present invention, the upper part of the sauna box is configured in a substantially airtight state, the air outlet for blowing out humidified air from the humidifying means is provided near the ceiling of the sauna box, and the lower part of the sauna box is A ventilation hole was provided, and the air inside the sauna box was configured to be exhausted from the ventilation hole using a fan provided in the ventilation hole. Therefore, since there is no other airflow in the upper part of the sauna box, the humidified air in the upper part of the sauna box can be smoothly moved downward by the fan without being affected by the other airflow. . Therefore, the humidified air is almost evenly distributed from the top to the bottom inside the sauna box without causing convection or turbulence, and
Since the temperature difference between the upper and lower parts of the sauna box can be made much smaller than before, it is possible to obtain a favorable bathing condition that prevents head cold and feet heat due to the humidified air, which greatly increases the bathing effect of the sauna bath. can be improved.

In addition, an outlet for ejecting humidified air from the humidifying means is provided near the ceiling of the sauna box, and the humidified air is almost evenly distributed within the sauna box from the top to the bottom by a fan. did. Therefore, since the humidity inside the sauna box is relatively high, almost the same effect can be obtained even if the temperature inside the sauna box is not raised to that high, and this reduces the burden on the heart of the bather. can be done.

In addition, ventilation holes are provided at the bottom of the sauna box,
The air in the sauna box was configured to be discharged from the ventilation hole by a fan provided in the ventilation hole. Therefore, since the inside of the sauna box can be made negative pressure, air leakage inside the sauna box can be eliminated and the temperature inside the sauna box can be maintained at a good level, which reduces wasteful power consumption of the heater. can be suppressed.

In addition, since the upper part of the sauna box is constructed in a nearly sealed state, even when the fan is stopped, warm air from the upper part can still flow through the ventilation hole, compared to a case where an intake vent is provided at the top of the sauna box. There is no chance of it escaping to the outside upwards. Therefore, the temperature inside the sauna box can be maintained even better, and therefore, wasteful power consumption of the heater can be further suppressed.

Further, since the fan is used simply to lower the air from above, there is no need to use a particularly large-capacity fan, and a small-capacity fan may be used, which is economical.
