Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a sauna dryer that effectively uses the heat of a panel heater.

[Background technology]

As shown in FIG. 4, a sauna dryer 8 is known which includes a chamber 1 for trapping hot air, and a panel heater 4 is provided along the wall 22 of the chamber 1. This type of dryer is called a sauna dryer because it is used not only as a sauna but also for drying clothes, etc.

In FIG. 4, 9 is a chair, 10 is a temperature controller, 11 is a door, and 12 is a window.

The conventional sauna dryer, as shown in Figure 5,
Laundry bar 2 spanning between walls 22 of sauna room 1
Dry clothes 3... are hung on the wall, and the dried clothes 3... are heated by direct heat radiation from the panel heater 4.
Alternatively, it was heated by indirect heating from heated air to evaporate the moisture it contained and dry it. The air containing water vapor is removed by the exhaust fan 7.
The dry air is discharged to the outside through the air intake port 6, and the dry air from the outside is introduced through the intake port 6. In addition, in order to disturb the indoor air and promote moisture evaporation from dry matter, a fan 5 is installed at the bottom of the sauna room 1 as shown in the figure.
The air in sauna room 1 was also circulated by blowing air from below.

However, the air from the fan 5 directly hits the dried material 3 from below, opening the lower part of the dried material 3 as shown in the figure and blocking it from passing upward, which causes uneven drying of the dried material 3. was. In addition, the temperature of the air in the lower part of the sauna room 1 is low, and since the fan 5 is usually located near the intake port 6, the cold air coming in from the intake port 6 is also transferred to the dry material 3. It also had the disadvantage of being inefficient because it involved guessing. As shown by the arrow, the air heated by the panel heater 4 may rise without hitting the dry matter 3 and be discharged as is by the exhaust fan 7, so the heat of the panel heater 4 can be fully utilized. There were some imperfections that weren't cut.

In order to speed up the drying speed, it is most necessary to raise the temperature of the drying material 3, and there is almost no need to warm the air surrounding the drying material 3. However, with conventional sauna dryers, Since the air was heated and the heated air was used to raise the temperature of the dried material 3 for drying, there was a drawback that the heat from the panel heater was often wasted.

[Purpose of the invention]

This invention was made in view of the various shortcomings of the conventional sauna dryer as described above, and it effectively uses the heat of the panel heater, enables faster drying of dried items, and also reduces uneven drying. The purpose is to provide a sauna dryer with less.

[Disclosure of the invention]

This invention provides a sauna dryer that is equipped with a chamber that traps hot air and a panel heater is installed along the wall of the sauna dryer. Directly below this fan, there is a fan that circulates the air downward. Directly below this fan, there are openings at the top and bottom. The hot air blown down by the fan is received from the upper opening, and the received hot air is blown downward from the lower opening. A chamber is installed on the ceiling of the room, with one end facing near the wall where the panel heater is installed and an exhaust duct with the other end open to the outside, and one end open to the outside and the other end facing the fan. A sauna dryer characterized in that an air supply duct facing upward is formed, and a heat exchanger for exchanging heat between the inside of the air supply duct and the inside of the exhaust duct is provided between both ducts. This will be described in detail below based on drawings showing examples thereof.

In FIGS. 2a and 2b, reference numeral 20 denotes a fan, which is installed at the upper part of the sauna room 1. Immediately below the fan, there is a chamber 21 which has openings at the top and bottom and a shape that widens downward. is installed.

The air entering the sauna room 1 from the intake port 6 is
It is heated by the panel heater 4 attached to the wall 22, becomes warm air, and rises above the sauna room 1 as shown by the arrow.

This warm air is circulated through the sauna room 1 from the top to the bottom by the fan 20. Further, since the chamber 21 is attached directly below the fan 20, the chamber 21 receives the hot air blown down by the fan 20 from the upper opening, and blows it out in a downwardly expanding shape from the lower opening. In this way, the warm air is rectified by the chamber 21, and the warm air is evenly applied from above to the dry clothes 3 hanging on the washing bars 2, 2 of the sauna room 1.

A portion of the dried material 3 close to the panel heater 4 is heated by radiation from the panel heater 4 (indicated by a thin arrow). Exhaust is performed through an upper exhaust port 28.

In this way, the air heated by the panel heater 4 is evenly applied to the entire drying material 3 from the upper part by the action of the fan 20 and the chamber 21, and the panel heater 4 also directly radiates heat onto the drying material 3. drying with good thermal efficiency.
Dry material 3... is dried quickly and evenly.

Next, on the ceiling of the room, there is a panel heater 4 at one end.
An exhaust duct 24 facing near the wall where the fan 20 is provided and the other end open to the outside, and an air supply duct 25 having one end open to the outside and the other end facing above the fan 20 are formed. A heat exchanger 26 for exchanging heat between the air duct 25 and the exhaust duct 24 is provided between the two ducts.

At the top of the sauna room 1, a partition plate 27 is provided that extends from the top of the chamber 21 toward the wall surface where the panel heaters 4, 4 are provided. In the diagram,
28 is an exhaust port, 29 is an exhaust fan, and 30 is an air supply port.

The air heated by the panel heaters 4, 4 is
It ascends in the sauna room 1, is guided by a partition plate 27, is circulated downward by a fan 20 and a chamber 21, and is applied to the dried objects 3, thereby evenly drying the entire dried objects 3.

Exhaust gas in the sauna room 1 is sucked up by an exhaust fan 29, passes through an exhaust duct 24, and is discharged from an exhaust port 28. At this time, the heat exchanger 26 provided between the exhaust duct 24 and the air supply duct 25 exchanges heat between the exhaust air and the air supply from outside.

The heat-exchanged exhaust gas is exhausted from the exhaust port 28,
On the other hand, the supply air heated by heat exchange is
0 sucked into sauna room 1, sauna room 1
circulate within.

According to this embodiment, the heat exchanger 26 exchanges heat between the hot exhaust gas and the air supplied from outside, so that the air heated by the panel heater 4 can be used effectively, resulting in good thermal efficiency. Further, since the partition plate 27 is provided, there is also an effect of preventing a short circuit in the circulating air flow, as shown in section Y in FIG. 1, which shows the structure of the comparative example without the partition plate 27.

3a, b, c, and d show other embodiments in which a gap is provided between the panel heaters 4, 4 and the walls 22, 22, and the wall side end of the partition plate 27 is Curtains 31, 31 that do not block the radiation of the panel heaters 4, 4 are hung below, and this partition constitutes a simple duct that covers the front of the panel heaters 4, 4. The curtains 31, 31 can also be rolled up so that they do not get in the way when the sauna is used.

In the figure, 32 is an exhaust duct provided at a corner of the wall 22, and an entrance 33 on the sauna room 1 side is provided at the bottom. Figure 3a shows this duct 32.
In order to express this, the duct portion is shown protruding outward from the other figures b to d. In the figure, 29 is an exhaust fan, and 34 is an air supply fan.

The air heated by the panel heaters 4, 4 is
2, 22 and the panel heaters 4, 4 and the gap between the panel heaters 4, 4 and the curtains 31, 31. circulated downward. In addition, the moisture in the dry matter 3... is evaporated, and the humid, low-temperature, used air falls below the sauna room 1, passes through the exhaust duct 32 from the inlet 33 at the bottom of the sauna room 1, and exchanges heat with the supply air. The air is then discharged to the outside from the exhaust port 30 on the ceiling of the sauna room 1.

According to this embodiment, the panel heater 4 and the wall 22
Since there is a gap between the panels, the air between them acts as a heat insulator, and the radiant heat from the panel heater 4
This has the effect of preventing heat from being radiated outside through the wall 22. Further, since a curtain is provided below the wall side end of the partition plate 27, there is an effect of preventing a short circuit in the circulating flow as shown in the Z section shown in FIG. 2a of the above embodiment. Since the exhaust duct 32 is provided at the corner of the sauna room 1, the exhausted low temperature and high humidity exhaust gas is discharged from the lower inlet 33 through the exhaust duct 32. 4,4
There is no wastage of heat as air heated by radiation is discharged as is, and there is an advantage that the amount of waste heat can be further reduced.

The panel heater 4 is usually an electric type, but is not limited to this, and may include a hot water type, a heat panel type, etc.
Any panel-shaped heat source can be applied.

The fan 20 is not limited to the cross flow fan shown in the figure, but can also be used with other shapes and structures.

Heat exchangers are not limited to the heat pipes shown in the figure.
It can also be used with other structures.

〔Effect of the invention〕

Since the present invention has the above-described structure, the heat from the panel heater is effectively utilized by the fan and the chamber, thereby increasing the drying speed and having an excellent effect of reducing drying unevenness.

In particular, since the panel heater for the sauna is also used as the heat source for drying, there is no need to provide a special heat source for drying, making it economical. Efficient drying can be achieved by both heating with air heated by a heater.

In other words, the sauna room is originally equipped with a panel heater for use in sauna bathing, so if you use this panel heater to dry clothes, etc., you can save the cost of installing a separate heater for drying. can be reduced and is economical. However, although the radiant heat from the panel heater can sufficiently heat and dry the portion facing the panel heater, the heat is not sufficiently transmitted to the portion not facing the panel heater. Therefore, in this invention, a fan is provided in the upper part of the sauna room. The surrounding air is sufficiently heated in the area that comes into contact with the panel heater or in the vicinity, and the heated hot air rises. By circulating this increased hot air from top to bottom using the fan, it is possible to heat and dry clothing, etc. by applying sufficient hot air to areas that could not be heated and dried using only the radiant heat of the panel heater. It will become.
In other words, the thermal energy of both the radiant heat of the panel heater and the hot air from the air heated by the panel heater can be used to dry clothes, etc. without waste, and this can greatly contribute to effective use of thermal energy and shortening of drying time. become.

Next, in this invention, an air supply duct and an exhaust duct are provided separately on the ceiling of the room, and a heat exchanger is provided to exchange heat between the two, thereby making thermal energy more effective. It can be used. In the case of a dryer, a large amount of water and humidity comes out from clothes, etc., so it is necessary to drain this water. Therefore, conventional dryers discharge moisture by exhausting hot air containing moisture, but at the same time as exhausting moisture, the hot air, which contains a large amount of thermal energy, is also discarded. . In addition, since cold air from outside enters in the amount of hot air that is exhausted, there is a problem that the temperature of the hot air that has been heated to a high temperature drops, which wastes a lot of thermal energy and is uneconomical. . Therefore, in this invention, the heat exchanger described above can take away thermal energy from high-temperature exhaust gas containing moisture, and provide this stolen thermal energy to fresh supply air taken in from the outside, so that thermal energy can be effectively used. It can be used for. Since the exhaust air and supply air are completely separated in each duct and exchange heat, there is no need to worry about moisture contained in the exhaust air mixing with the supply air.
