Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying / humidifying device used at home.

[0002]

2. Description of the Related Art Conventionally, there has been no household device integrated as a dehumidifying / humidifying device, and most of the dehumidifying device and the humidifying device have been used as a single unit.

As a conventional dehumidifying device, there are a device to which a heat pump is applied, a device by electronic cooling, and a disposable device using a dehumidifying agent such as calcium chloride. Also,
As a humidifier, there were a spray method, an ultrasonic method, a vaporization method, and the like.

[0004]

However, the above-described conventional dehumidifiers and humidifiers have not only the problem that the devices are not integrated, but also the problem that the treatment of water supply and drainage is necessary. That is, in the case of the dehumidifier, piping work for draining the collected water or work for periodically draining the water is required, and in the case of the humidifier, it is necessary to constantly replenish the water for humidification.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a maintenance-free dehumidifying / humidifying device that can be reused.

[0006]

In order to achieve the above object, the present invention blows out air sucked from a first opening other than the humidifying space to be blown out from a second opening in the humidifying space to be removed. No. 1 air passage, a second air passage for blowing air sucked from the first opening to a third opening other than the humidifying space to be removed, and adsorbing and holding moisture in the air while allowing air to pass therethrough. Or an adsorbent for releasing the water already held into the air, a heater for drying the adsorbent, and a blower for flowing air through the first and second air passages, Control means is provided for simultaneously turning on / off the heater and switching the air passage, and the first and second air passages share a part thereof, and the adsorbent and the heater are arranged in the shared portion. Together with the control means, Of flowing air into the air blowing passage and not energizing the heater, and alternating state 2 of flowing air into the second air blowing passage and energizing the heater, and the air flowing into the second air blowing passage. And the state 3 in which the heater is not energized and the air is passed through the first air passage, and
It is configured such that the state 4 in which the heater is energized can be alternately repeated.

[0007]

According to the present invention, in the above-mentioned structure, in a state 1 in which the air is passed through the first air passage and the heater is not energized, the air other than the humidified space to be dehumidified is sucked and the air dehumidified by the adsorbent is dehumidified Blow into space. In the state 2 in which the air is passed through the second air passage and the heater is energized, the air sucked from other than the space to be humidified is accompanied by the moisture released from the adsorbent heated by the heater, Since it is discharged to a space other than the dehumidified space, the adsorbent can be reused.

Therefore, by switching between the state 1 and the state 2, the dehumidified dry air is sent to the space to be humidified, and the inside can be kept in a dry atmosphere.

On the other hand, in the state 3 in which the air is allowed to flow through the second air passage and the heater is not energized, the air other than the humidifying space to be removed is sucked in, the moisture is supplied to the adsorbent, and the dry air is then humidified to be removed. Blow out to a place other than space. Further, in the state 4 in which the air is made to flow in the first air passage and the heater is energized,
Air sucked from other than the humidification space to be removed is discharged to the humidification space to be removed together with the moisture released from the adsorbent heated by the heater. Will be possible.

[0010]

Embodiments of the present invention will be described below with reference to FIGS.

In FIGS. 1 and 2, 1 is a first opening facing the non-humidified space to be removed, 2 is a second opening facing the humidified space to be removed, and 3 is a surface other than the humidified space to be removed. This is the third opening. The first air passage 4 connecting the first opening 1 and the second opening 2 and the air passage 5 connecting the first opening 1 and the third opening 3 share a part, and An adsorbent 6 and a blower 7 are arranged in the portion. A heater 8 is provided around the adsorbent 6. Reference numeral 9 denotes a blower passage switching unit that switches the air after passing through the adsorbent 6 to the second opening 3 or the third opening 3.

Next, the operation of the embodiment of the present invention and the principle of the dehumidifying / humidifying action will be described. In the above configuration, when the blower 7 is operated, a flow for sucking air from the first opening 1 is generated. The sucked air passes through the adsorbent 6 and the second opening 2, depending on the direction of the air passage switching unit 9,
Alternatively, it is blown out from the third opening 3. At this time, as shown in FIG. 1, if the ventilation passage switching unit 9 is set so as to guide the flow to the second opening 2 and the heater 8 is not energized, it is sucked from the opening 1. When the air passes through the adsorbent 6, the adsorbent 6 deprives the adsorbent 6 of contained water and is discharged from the opening 2 as dry air. Therefore, since the dry air is supplied to the humidified space to be removed, the entire space can be kept in a dry atmosphere.

However, since the adsorption capacity of the adsorbent 6 is finite, it becomes saturated when a certain amount of water is adsorbed. Therefore, after continuing the above operation for a certain time, the adsorbent 6
Perform the regeneration operation of. In the regeneration operation, as shown in FIG. 2, the air passage switching section 9 is set so that the air after passing through the adsorbent 6 is guided to the third opening 3, and at the same time, the heater 8 is energized to heat the adsorbent 6. To do. By this heating operation, water is desorbed from the adsorbent 6 and the adsorbent 6 is regenerated. The desorbed water is carried to the third opening 3 together with the air passing through the adsorbent 6, and is discharged from the third opening 3 to a space other than the humidification space to be removed. In this way, when the adsorbent 6 is regenerated and the water supply performance is restored, it is possible to send the dry air to the humidification-removed space by returning to the initial operating state again. Therefore, by repeating these two operations, the humidified space to be removed can be kept in a dry atmosphere.

On the other hand, the humidification of the space to be humidified can be performed by switching the ventilation passage and reversing the on / off state of the heater. That is, when the air sucked from the opening 1 is discharged to the opening 3, the heater 8 is not energized, and the moisture in the air taken in from other than the space to be humidified is removed by the adsorbent 6.
Store in. Then, the air passage is switched to open the opening 2
When it is blown out to, the heater 8 is energized to desorb the water stored in the adsorbent 6, and the high-humidity air is discharged to the humidifying space to be removed. By doing this, it is possible to take in air that contains more water than the air outside the humidified space, and it is possible to obtain a sufficient humidifying effect even if the air outside the humidified space does not contain much water. I can.

As is clear from the above description, in the dehumidifying / humidifying device of the present invention, the moisture in the air is used for humidification, and the dehumidified moisture is released into the air again through the adsorbent 6.
Maintenance-free operation is possible without the hassle of water supply and drainage.

Further, if the blower 7 capable of blowing in both the forward and reverse directions is used, air is sucked in through the opening 2,
A flow that blows out into the opening 1 can be generated. As a result, it is possible to perform an exhaust action that positively sends the air in the humidifying space to be removed to a space other than the humidifying space to be removed. Also in this case, since the adsorbent 6 and the heater 8 are arranged in the air passage, it is possible to perform ventilation while suppressing the inflow and outflow of moisture, and to provide a dehumidifying / humidifying action by providing only one opening in the humidifying / dehumidifying space. Ventilation can be performed at the same time. For example, when the humidified space to be removed is in a high humidity condition and the space other than the humidified space to be removed is a dry atmosphere, the moisture of the exhausted air is stored in the adsorbent 6 and the heater 8 is used at the time of inhalation in which the blowing direction is changed. By heating the adsorbent 6 to remove water, it is possible to ventilate while keeping the humidity in the humidified space to be removed high. At this time, it is possible to further humidify by combining with the above-mentioned humidifying operation.

Similarly, it is also clear that by combining the above-described dehumidifying operation and exhaust operation, it is possible to perform ventilation while maintaining the dry atmosphere of the dehumidifying / humidifying space.

[0018]

As described above, according to the dehumidifying / humidifying device of the present invention, the following effects can be obtained by the adsorption / desorption action of water by the adsorbent and the switching of the air passage.

(1) Since it is possible to switch whether the air after passing through the adsorbent is blown out to the humidified space to be removed or the humidified space to be removed, it is possible to combine adsorption and desorption by turning on and off the heater. The dehumidifying / humidifying action can be performed by freely taking out dry air or humid air.

(2) The moisture in the air is taken into the adsorbent to humidify the adsorbent, and the dehumidified moisture is released to the space other than the dehumidifying and humidifying space through the adsorbent, so that no labor for water supply or drainage is required. .

(3) By using a blower in both the forward and reverse directions, the dehumidifying / humidifying action and the ventilation action can be performed by providing only one opening in the dehumidifying / humidifying space.
