In addition, indoor 5
If the room 0 has a condition that does not generate dust, the first filtering portion 95 may be omitted.

The second filtering portion 22 is a portion formed of a filtering material made of a porous synthetic resin material such as a sponge having fine ventilation holes, and removes fine dust such as pollen. For example, it is configured to remove fine dust having an outer shape of 0.1 mm or less.

The first filtration portion 95, the second filtration portion 22, and the third filtration portion 21 can be ventilated only in the flow direction of the flow path by surrounding the periphery with a suitable plate material. , So that the outside of the flow path is not leaked,
Further, the outer shape may be changed to an outer shape similar to the outer shape of each flow path, for example, a circular shape. Further, each flow path 24, 41
-Each flow path of the part belonging to 91 may be changed to a tubular flow path having a rectangular cross section.

Further, the portions of the flow paths 24B and 67 may be made very short. In addition, by minimizing the portion of such a flow path as much as possible, for example, the inside of a cubic outer box is divided into a plurality of sections, and each section is arranged in each of the sections, so that the whole is configured as one body.

The heating and dehumidifying portion 82 and the residual heat and dehumidifying portion 83 are distributed in a ratio of about 3: 1: 1. That is, when viewed from the fan-shaped angle of the end face 80X, the moisture absorbing portion 81: the heating and dehumidifying portion 82: the residual heat and dehumidifying portion 8
3 = 216 °: 72 °: approximately 72 °.

The volume of the target room 10 is 30 to 40 m
^In the case of ³ , the outer diameter D1 is 20 c
m, the height H1 is about 5 cm, and the amount of air Q1 for passing air through the moisture absorbing portion 81, the amount of air Q2 for passing air to the heating and dehumidifying portion 82, and the amount of air for passing air through the residual heat and dehumidifying portion 83. The amount Q3 is, for example, Q1: Q2: Q3 = 80 cm
³ / h: 30 cm ³ / h: set to about 30 cm ³ / h.

It is to be noted that the moisture absorbing part 81, the heating and moisture releasing part 82,
The residual heat dehumidifying portion 83 is not fixed to the moisture absorbing and desorbing body 80, and is independent of the rotation of the moisture absorbing and desorbing body 80 when viewed from a stationary portion of the apparatus 500, for example, from each channel. The portions are sequentially shifted by the same amount as the rotation amount so that a fixed portion always becomes the moisture absorbing portion 81, the heating and dehumidifying portion 82, and the residual heat and dehumidifying portion 83.

The heating portion 88 for passing the outside air 11 with the heating / dehumidifying portion 82 in a heated state is provided by, for example, electric heating using a nickel chrome steel wire as described above.
The heating unit 88 is configured to heat the outside air 11 and / or the heating / humidifying unit 82, and the heating unit 88 is energized only when the humidifying operation is performed by the control unit 200. .

The remaining heat / humidification portion 83 is a portion where the heat energy of the portion whose temperature has risen due to the above-mentioned heating is rotated while remaining as the remaining heat, so that the heat energy is not wasted. The air before passing through 82 is passed through the residual heat release section 83 to release the water by the residual heat, and the release of the water cools the residual heat release section 83 and the next moisture absorption. The circulation operation of returning to the portion 81 is performed.

The portion where the moisture absorbing / discharging body 80 and each flow path face each other is divided, for example, as shown in FIG. 4 so as to oppose both sides of the moisture absorbing portion 81, the heating moisture releasing portion 82, and the residual heat moisture releasing portion 83. A cover 85A having the hollow portions 81A, 82A, 83A and a cover 85B having the hollow portions 81B, 82B, 83B are provided, and the channels 24C, 24D, the channels 91B, 91C, and the channels 91D, 91E are provided respectively.

In each drawing, the size of each part of the device 500 is drawn much larger than the actual size of the room 50 for easy understanding of the configuration.

In the normal state, the room 50 has the opening / closing portion 5.
Since the outside air 11 enters the room 50 by the opening / closing operation of the 2 · 53, the air 50A existing in the room 50 is ventilated with the outside air 11. When the opening and closing portions 52 and 53 are closed, ventilation is similarly performed through a small gap between the opening and closing portions 52 and 53.

Because of the natural ventilation, in the spring, for example, outside air containing fine dust such as pollen, for example, cedar pollen, enters the room 50 as it is. You will be bothered by the disease.

In such a season, when the device 500 is operated by the cleaning operation shown in FIG. 2, the air 50A in the room 50 quickly becomes the clean air 51.
Even if some outside air 11 directly enters the room 50 by the opening and closing operation of the room 53, the room 50 can always be the clean air 51 that does not contain such fine dust.

In the winter season, the humidity of the outside air 11 also decreases, but the humidity of the air 50A in the room 50 becomes further lower than the humidity of the outside air 11, so that a person resident in the room 50 may hurt his throat. , Which makes it easier to catch a cold.

In such a season, the humidified air 51A is supplied to the room 50 by operating the device 500 by the moisture absorbing operation and the humidifying operation shown in FIG.
Can always be kept in a humidified state.

The external air supply operation is performed as shown in FIG.
When the flow path switching portion 27 is switched to flow from the flow path 24B to the flow path 67 to make the flow 67 in a flow state, the external air 11 is separated from the flow path during the cleaning operation of the air 50A in the room 50. 24A → third filtration part 21 → flow path 24
The outside air 11 is supplied to the room 50 as the clean air 51 through the flow passage 67 of B → flow passage switching portion 27 → flow passage 67 → return portion 66 → flow passage 41B → forced ventilation portion 23.

Performing the above-described cleaning operation fluctuates the air pressure of the air 50A in the room 50. As a result, fine dust, such as pollen, is contained in the gap between the opening and closing portions 52 and 53 with the fluctuation. The outside air 11 will enter.

Therefore, when the outside air 11 is supplied from the above-mentioned flow channel 67 so that the outside air 11 is converted into the clean air 51 and sent into the room 50, the air 50 A in the room 50 operates so as to leak out to the outside 10 from the gap between the opening / closing portions 52 and 53. 10
From the room 50 containing fine dust such as pollen
It is possible to prevent the intrusion.
