Description

[Detailed Description of the Invention] With the rapid changes in the living environment, our lifestyle has been greatly affected, and changes are required in various fields.

In particular, the modern waves of industrialization, motorization, urban concentration, etc. have inevitably made our living environment narrower, higher-rises, and housing complexes, and as a result, even when it comes to drying laundry. It has become difficult to do this using the traditional drying area in the garden or on the roof. As an alternative to these, the use of °C1 baths has come to be considered an effective means, taking into consideration the moisture that evaporates during the drying process.

The most important factor in drying is the difference in water vapor pressure on the surface of the object to be dried, and therefore the drying rate increases as the relative humidity of the drying air decreases.

The present invention was made with attention to this point, and its characteristics are that dry air is chemically adsorbed or passed through an absorbent type moisture absorbent, and that it is heated to a higher temperature. The purpose is to lower the relative temperature as much as possible and to rationally regenerate the moisture absorbent after drying.

To explain the features of the present invention with reference to the figure which is an example thereof, Fig. 1 is a perspective view of a moisture absorption tower (8) attached to the exhaust part (2) of a bathroom heating device +1). During drying operation, the arrow mark (6) is drawn from the drying air supply port (4).
Air is supplied in the direction of the moisture absorbent (8) in the moisture absorption tower (8).
), the air whose relative humidity has decreased is sent to the regeneration air supply port (5
), follow the arrow (6) and be guided into the bathroom dryer.

The effect will be further increased if the temperature is raised by another heating device and the relative humidity is further lowered just before being introduced into the bathroom dryer.

The desiccant (8) to be filled in the drying tower (8) is an adsorbent such as licage gel or alumina gel, or an absorbent such as calcium chloride, phosphorus pentoxide, or any other commonly used moisture absorbent.
-4 Good.

After drying, it is desirable to keep the moisture adsorbed by the moisture absorbent (8) as low as possible for the next drying process. The regeneration of the so-called moisture absorbent is carried out when using the bathroom heating device (1) for bathing, and at this time the exhaust section (2) of the device is used.
), a large amount of heat accompanying exhaust gas is lost as heat loss.

By utilizing the waste heat generated by the waste heat generated by wastewater, regeneration can be carried out in an economical and energy-saving manner. That is, while heat is generated in the bath heating device +1) and hot water for bath i is prepared, the waste heat discharged together with combustion products such as water and waste gas is transferred to the moisture absorption tower (8). Heated, the temperature of the moisture absorbent (8) increases. Therefore, the water adsorbed and absorbed in the moisture absorbent evaporates and becomes a gas as the water vapor pressure increases. At this time, in the opposite direction to the drying time, follow the arrow (7) to the regeneration air supply port (
5), the moisture is discharged out of the system from the dry air supply port (4) via the moisture absorbent (8), and the moisture absorbent is regenerated.

Figure 2 shows a moisture absorption tower (8) placed outside the exhaust section (2) of the bathroom heating device (1), and dry air connected to the moisture absorption tower through the regeneration air supply port (5) in the exhaust section. FIG. 2 is a perspective view of an apparatus equipped with a heating tower (9). During the drying operation, the bathroom heating device +1) is operated at the same time, and the dry air heating tower (9) is heated by the transfer of waste heat in the exhaust section 12). At the same time, the dry air follows the arrow (6) and enters the moisture absorption tower (8) from the dry air supply port (4), and the moisture is adsorbed or absorbed by the moisture absorption agent (8), resulting in a decrease in relative humidity. do.

Furthermore, the first drying air enters the drying air heating tower (9) via the regenerating air supply port (6), whereupon the heating temperature rises, the relative humidity further decreases, and the drying air enters the drying room through the drying air outlet 16. is induced.

After drying, in order to regenerate the absorbed moisture absorbent (8), air is made to flow in the direction opposite to that during drying according to the arrow (7). That is, the regeneration air introduced into the dry air heating tower (9) K from the dry air outlet lid is heated by the exhaust heat of the exhaust section (2), and is then transferred from the regeneration air supply port (6) to the moisture absorption tower (8).
), the temperature of the moisture absorbent (8) loaded in the tower is increased, the water vapor is desorbed or volatilized, and the water vapor is discharged from the system through the dry air supply port (4).

The example shown in FIG. 2 exhibits its characteristics when applied, for example, in a bathroom equipped with a bathroom heating device for supplying hot water, where the heating device is constantly working.

As mentioned above, the present invention provides an extremely effective means for reducing the relative humidity of dry air or regenerating moisture absorbents by utilizing waste heat from equipment required for other purposes, thereby achieving efficient drying. , can yield energy saving fruits.
