Description

dehumidifier

technical field

The present invention relates to dehumidifiers.

Background technique

There are a refrigeration cycle type and a zeolite type as an apparatus for performing dehumidification and humidity control. The "refrigeration cycle type" mainly uses a built-in compressor, that is, a compressor, and uses an evaporator, that is, an evaporator to cool the indoor air so that the humidity in the air is condensed and dehumidified. "Zeolite type" makes the rotor absorb the moisture in the indoor air, makes the high-temperature warm air generated by the electric heater hit the rotor after moisture absorption, and takes out the moisture in the rotor as high-temperature and high-humidity air, and uses the indoor air By cooling the air, moisture contained in the high-temperature, high-humidity air is condensed and taken out. In addition, as described in JP-A-2009-180433 (Patent Document 1), there is also a method of using flammable lithium chloride (LiCl ₃ ) or the like as a wet drying agent.

As a document describing an example of the refrigeration cycle type, JP-A-2003-144833 (Patent Document 2) can be cited. As a document describing an example of the zeolite formula, JP-A-2001-259349 (Patent Document 3) can be cited. A configuration combining the features of both is described in Japanese Unexamined Patent Publication No. 2005-34838 (Patent Document 4).

On the other hand, Japanese Unexamined Patent Application Publication No. 2002-126442 (Patent Document 5) describes a gel sheet that dehumidifies and absorbs water using a gel whose water absorption characteristics change with a phase transition temperature as a boundary.

The problem to be solved by the invention

In the refrigeration cycle type using a compressor as a mechanism for dehumidification and humidity control, it is possible to perform high-efficiency dehumidification and humidity control such as a refrigeration efficiency COP of 5 in principle. However, in the above-mentioned refrigerating cycle type, there are still problems such as the use of halogen-based gases that cause environmental damage, difficulty in increasing the size due to the installation of a compressor, and high noise. On the other hand, in the zeolite type, regeneration heat of 200°C or higher is required, and the efficiency is poor. However, the hybrid type in which the above-mentioned methods are integrated uses part of the compression heat of the compressor for the regeneration of the zeolite rotor, etc., and can be improved. The range of application of the zeolite type is expanded, but a complicated air path or mechanism is required, and an increase in size cannot be avoided. In addition, there is no change in condensation of water vapor collected by absorption or the like by supersaturated cooling.

In addition, if it is a moisture-absorbing component that requires high temperature as regeneration heat, hot air generated by a heater and a fan hits the moisture-absorbing component on the regeneration side, and the resulting high-temperature and high-humidity air is converted into condensed water through a heat exchanger.

Therefore, an object of the present invention is to provide a dehumidifier capable of reducing the size of the device without using a halogen-based gas and having low noise.

detailed description

(Embodiment 1)

A dehumidifier 101 according to Embodiment 1 of the present invention will be described with reference to FIG. 1 . FIG. 1 is a diagram conceptually showing the structure of a dehumidifier 101, and the actual size ratio and positional relationship of each part are not limited thereto. The dehumidifier 101 is provided with: a hygroscopic member 2, which is formed of a polymer gel hygroscopic material, has a first state capable of absorbing moisture and a second state of releasing moisture absorbed in the first state, and has The property that the above-mentioned first state changes to the above-mentioned second state and returns to the above-mentioned first state when the above-mentioned stimulus disappears; the external air supply part 4 makes the air taken in from the outside contact the moisture-absorbing member 2; and the stimulus imparting part 5 , which applies the above-mentioned stimulus to the hygroscopic member 2 without causing the airflow to hit the hygroscopic member 2 .

In the dehumidifier 101 , humid air 3 is taken in from the outside, and is guided through the external airflow supply part 4 so as to come into contact with the hygroscopic member 2 . The dehumidified air 3 brought into contact with the hygroscopic member 2 is blown out as air 6 with reduced humidity. The stimulus imparting part 5 applies a stimulus to the hygroscopic member 2, whereby water is taken out from the hygroscopic member 2, and the water receiving container 7 catches the water. The water receiving container 7 is not necessary.

According to the present embodiment, it is possible to provide a dehumidifier that can reduce the size of the device without using a halogen-based gas and has low noise.

In addition, it is preferable that the moisture is directly taken out from the moisture-absorbing member 2 in a liquid state by the above-mentioned stimulus applied by the stimulus imparting part 5 . According to this configuration, since moisture is directly taken out in a liquid state, a heat exchanger is unnecessary.

In addition, it is preferable that the above-mentioned stimulation is a stimulation using any one of heat, light, electricity, and pH. According to this configuration, stimulation can be easily controlled.

Here, the positional relationship between the hygroscopic member 2 and the stimulus imparting part 5 is roughly shown. The hygroscopic member 2 is a part that absorbs moisture in contact with the air 3 and is then stimulated by the stimulus imparting part 5 to discharge moisture. In order to realize this structure, it is preferable that the part which receives the stimulus from the stimulus imparting part 5 in the moisture-absorbing member 2 can be replaced suitably. For example, the moisture-absorbing member 2 may be relatively displaced with respect to the stimulus imparting part 5 by rotating or sliding. It is also possible to select which part of the moisture-absorbing member 2 is to be stimulated by providing a plurality of stimulus imparting parts 5 and selecting and operating any one of them.

The external airflow supply part 4 may also be relatively displaced or replaced with respect to the hygroscopic member 2 in the same manner.

In addition, since the hygroscopic member 2 of the dehumidifier 101 is opened downward, the water|moisture content taken out directly from the hygroscopic member 2 in a liquid state falls with gravity as it is. In this case, the stimulus imparting part 5 may be provided in either upstream of the moisture-absorbing member 2, or downstream. The stimulus imparting part 5 may be provided in both upstream and downstream of the moisture-absorbing member 2.

(Embodiment 2)

Dehumidifier 102 according to Embodiment 2 of the present invention will be described with reference to FIGS. 2 to 5 . A perspective view of the dehumidifier 102 is shown in FIG. 2 , and a cross-sectional view is shown in FIG. 3 . The dehumidifier 102 includes a housing 1 having an air inlet 11 and an air outlet 12 , and includes a moisture absorbing unit 20 inside the housing 1 . As shown in FIG. 3 , a slope 14 is provided below the moisture absorption portion 20 . The inclined surface 14 is able to catch the water discharged from the moisture absorption part 20 and collect it to the water outlet 15 . A water receiving container 7 is arranged below the water outlet 15 .

Inside the dehumidifier 102, as shown in FIG. 4, the some moisture absorption part 20 is arrange|positioned. The some moisture absorption part 20 is each a plate-shaped member. The some moisture absorption part 20 is mutually arrange|positioned with the gap 10 interposed. Each moisture absorption part 20 extends in the up-down direction. Therefore, the gap 10 also extends in the vertical direction, and the lower part of the gap 10 is opened. Each moisture absorption part 20 is arrange|positioned so that it may extend along the line which connects the air inlet 11 and the air outlet 12. As shown in FIG. The air 3 taken in from the outside and guided by the external airflow supply part 4 passes through the gap 10 between the moisture absorbing parts 20 as shown in FIG. In FIG. 5, the enlarged state of one moisture absorption part 20 is shown. One moisture absorption part 20 arrange|positions the planar heater 8 which is the stimulus imparting part 5 between two layered moisture absorption members 2. As shown in FIG. That is, the moisture absorption part 20 is provided with the moisture absorption member 2 and the stimulus imparting part 5. As shown in FIG.

Here, the configuration of the dehumidifier 102 will be organized and described. The dehumidifier 102 of the present embodiment is provided with: a hygroscopic member 2, which is formed of a polymer gel hygroscopic material, has a first state capable of absorbing moisture, and a second state capable of releasing moisture absorbed in the first state; The external stimulus changes from the above-mentioned first state to the above-mentioned second state and returns to the above-mentioned first state when the above-mentioned stimulus disappears; the external air flow supply part 4 makes the air taken in from the outside contact with the hygroscopic member 2; and The stimulus imparting part 5 applies the said stimulus to the moisture-absorbent material 2, without making airflow impinge on the moisture-absorbent material 2.

Here, the stimulus is heat, the hygroscopic member 2 is layered, and the stimulus imparting portion 5 is a heater arranged along the surface of the hygroscopic member 2 . The heater referred to here is the planar heater 8 . The heater as the stimulation imparting unit 5 is preferably the above-mentioned planar heater, but is not limited to the planar heater. The stimulus imparting part 5 should just be a heater arrange|positioned along the surface of the hygroscopic member 2, even if it is not a planar heater, for example.

In addition, the moisture-absorbing member 2 is layered, but the inside of each layer may be in any shape such as a block shape, a fine particle shape, or a shell shape.

In this embodiment as well, the effects described in Embodiment 1 can be obtained. Furthermore, in this embodiment, since the hygroscopic member 2 is layered, the air 3 taken in from the outside can be effectively brought into contact with most of the surface of the hygroscopic member 2, so dehumidification can be effectively performed. In addition, in this embodiment, since the heater as the stimulus imparting part 5 is arranged along the surface of the moisture absorbing member 2, stimulation can be effectively given to it in a wide range of the moisture absorbing member 2, and it is also possible to effectively stimulate the moisture absorbing member 2 from the moisture absorbing member 2. Remove the water.

Since the moisture absorbing part 20 extends in the vertical direction and the lower part of the gap 10 is open, the water discharged from the moisture absorbing member 2 can pass through the gap 10 and drop directly.

In addition, in this embodiment, it demonstrated that the hygroscopic member 2 changes from a 1st state to a 2nd state by receiving thermal stimulation. The fact that heat is selected as the type of stimulus here is only an example, and the moisture-absorbing member 2 may be a substance that changes from the first state to the second state by receiving other types of stimuli. This content is also the same in the following embodiments.

(Embodiment 3)

Dehumidifier 103 according to Embodiment 3 of the present invention will be described with reference to FIGS. 6 to 7 . A schematic perspective view of dehumidifier 103 is shown in FIG. 6 . The dehumidifier 103 includes a moisture absorption unit 21 . The moisture absorption part 21 is a disk-shaped member extended in a horizontal plane. The moisture absorption part 21 can be rotated by a motor. The center axis of the moisture absorption part 21 is a vertical direction. FIG. 7 shows a partially enlarged cross-sectional view of the moisture absorption portion 21 . The moisture absorption part 21 is honeycomb shape, and has the some through-hole 9 which penetrates in the thickness direction. The moisture absorption part 21 includes the part which consists of the moisture absorption member 2. As shown in FIG. The hygroscopic member 2 is exposed to the inner surface of the through hole 9 .

That is, the dehumidifier 103 of the present embodiment is provided with: the hygroscopic member 2, which is formed of a polymer gel hygroscopic material, has a first state capable of absorbing moisture and a second state that releases the moisture absorbed in the first state, and has The property of changing from the above-mentioned first state to the above-mentioned second state by an external stimulus and returning to the above-mentioned first state when the above-mentioned stimulus disappears; the external air flow supply part 4, which makes the air taken in from the outside come into contact with the moisture-absorbing member 2 and the stimulus imparting unit 5 that applies the above-mentioned stimulus to the moisture-absorbing member 2 without causing the airflow to impinge on the moisture-absorbing member 2 .

In this embodiment as well, the effects described in Embodiment 1 can be obtained. Furthermore, in the present embodiment, the moisture absorbing portion 21 including the moisture absorbing member 2 has a disc shape and a rotating structure, so that a certain portion of one moisture absorbing portion 21 can be used for moisture absorption, and other portions can be stimulated to extract water. . That is, moisture absorption and drainage can be performed in parallel. For example, the moisture absorption and drainage operations can be continuously performed without interruption by continuously rotating the disk-shaped moisture absorption unit 21 at a constant speed.

Alternatively, the disk-shaped moisture absorbing unit 21 may be rotated intermittently in a stepwise manner. That is, for example, in a state where the moisture absorption portion 21 is stationary, a certain portion of the moisture absorption portion 21 receives the air 3 and then absorbs moisture for a certain period of time, and then rotates the moisture absorption portion 21 by a certain angle to allow the next moisture absorption. Re-exposed to air 3 pose.

The dehumidifier of this embodiment can be expressed as shown in the following appendix.

(Appendix 1-1)

In the dehumidifier according to any one of the above, the moisture absorbing part is arranged on at least a part of a cylindrical member, the cylindrical member is rotatable around a central axis, and the external air supply part is formed by the cylindrical member. The air hits the moisture-absorbing part at a first location in a circle defined by the orbit drawn on the outer periphery of the above-mentioned circle, and the stimulation imparting part applies the stimulus to the moisture-absorbing part at a second location in the circle different from the first location.

(Appendix 1-2)

In the dehumidifier according to additional note 1, the moisture absorbing portion is arranged so that the central axis is in the up-down direction.

(Appendix 1-3)

In the dehumidifier according to Supplementary Note 1 or 2, the moisture absorbing portion has a honeycomb shape having through holes penetrating in a thickness direction.

(Embodiment 4)

Dehumidifier 104 according to Embodiment 4 of the present invention will be described with reference to FIGS. 8 to 11 . Schematic cross-sectional views of the dehumidifier 104 are shown in FIGS. 8 and 9 . The basic configuration of the dehumidifier 104 is the same as that of the dehumidifier 102 described in the second embodiment. The dehumidifier 104 is equipped with the moisture absorption part 22 instead of the moisture absorption part 21 inside. In the inside of the dehumidifier 104, the moisture absorption part 22 is arrange|positioned as the some moisture absorption part 22 is shown in FIG. The some moisture absorption part 22 is each a plate-shaped member. The some moisture absorption part 22 is mutually arrange|positioned with the gap 10 interposed. The direction of the moisture absorption part 22 or the gap 10 is the same as the direction of the moisture absorption part 20 demonstrated in Embodiment 2. As shown in FIG.

FIG. 8 shows a state where dehumidification is being performed in dehumidifier 104 . In FIG. 9, the dehumidifier 104 shows the regeneration and drainage of the moisture absorption part 22 in progress.

When the dehumidifier 104 performs the dehumidification operation, as shown in Figure 8, the air 3 taken in from the air inlet 11 by the blower fan 24 is hit against the moisture absorbing part 22, and after the air 3 is dehumidified, it is used as air 6 from the air. Exit 12 discharges. While the air 3 passes through the gap 10 , moisture is deprived by the moisture absorbing portion 22 . In FIG. 11, the enlarged state of one moisture absorption part 22 is shown. One moisture absorption part 22 is formed with the moisture absorption member 2 in layer form so that both surfaces of the base material 13 may be covered.

The dehumidifier 104 is equipped with the air inlet 31 which opens upward. Among them, the air inlet 31 is provided with an openable and closable cover 31a. In the state shown in FIG. 8, the cover 31a is closed. Between the air inlet 31 and the moisture absorption part 22, the ventilation fan 17 and the heater 18 are arrange|positioned as the stimulus imparting part 5. As shown in FIG.

When performing the moisture absorption part regeneration operation, as shown in FIG. 9, the cover 11a of the air inlet 11 is closed, and the cover 31a of the air inlet 31 is opened. The blower fan 24 stops. The blower fan 17 provided at the air inlet 31 is operated, whereby the outside air 25 is taken in from the air inlet 31 , and the air 25 is heated by the heater 18 to become hot air and goes to the moisture absorbing part 22 . The hot air passes through the gap 10 between the moisture absorption parts 22 by the operation of the blower fan 17 and the heater 18 . Thereby, thermal stimulation is applied to the hygroscopic member 2 contained in the hygroscopic part 22, and water is discharged from the hygroscopic member 2. The water falls downward after passing through the gap 10 . In addition, the hot air blown by the blower fan 17 may be discharged from the air outlet 12 similarly to the air 6 . An exhaust port may be provided separately for the hot air blown by the blower fan 17 .

In addition, the cover 11a and the cover 31a may also use the same member. A configuration may be adopted in which the same member reciprocates to alternately switch between the state of closing the air inlet 11 and opening the air inlet 31 and the state of closing the air inlet 31 and opening the air inlet 11 .

In this embodiment, the effects described in Embodiment 1 can be obtained. Moreover, in this embodiment, since the moisture absorption member 2 is layered, similarly to Embodiment 2, the air 3 taken in from the outside can be dehumidified efficiently. In addition, in this embodiment, since the ventilation fan 17 and the heater 18 are arrange|positioned as the stimulus imparting part 5, and since hot air can be sent to the moisture absorption part 22 from above, heat can be applied as a stimulus to the moisture absorption member 2. In this way, stimulation can be effectively given to the hygroscopic member 2 over a wide range, and the operation of taking out water from the hygroscopic member 2 can also be performed efficiently.

(Embodiment 5)

Dehumidifier 105 according to Embodiment 5 of the present invention will be described with reference to FIG. 12 . FIG. 12 is a schematic cross-sectional view of dehumidifier 106 . The dehumidifier 105 includes a housing 1 . The housing 1 has an air inlet 11 and an air inlet 31 on the upper side, and an air outlet 12 on the side. The dehumidifier 105 includes a disk-shaped and honeycomb-shaped moisture absorption unit 21 and a motor 16 that rotates the moisture absorption unit 21 inside the housing 1 . The detailed structure of the moisture absorption part 21 is the same as what was demonstrated in Embodiment 3. As shown in FIG.

The air 3 taken in from the air inlet 11 and entered into the housing 1 through the external air supply part 4 hits a part of the moisture absorbing part 21, passes through the through hole 9 (see FIG. 7 ) of the moisture absorbing part 21, and is dehumidified. The dehumidified air is discharged as air 6 from the side air outlet 12 .

The stimulation imparting unit 5 is disposed near the air inlet 31 . Stimulus imparting unit 5 includes blower fan 17 and heater 18 . The blower fan 17 is activated, whereby the air flow 19 is drawn in via the air inlet 31 . The airflow 19 is heated by the heater 18 and hits a part of the moisture absorption part 21 . In the moisture absorption part 21, the location where the airflow 19 taken in from the air inlet 31 hits is different from the place where the air 3 taken in from the air inlet 1 hits. The airflow 19 passes through the through-hole 9 of the moisture absorption part 21, and the stimulation, such as heat, is given to the moisture absorption member 2 of the moisture absorption part 21 by this. In this case, water is discharged from the moisture absorption portion 21 .

Below the moisture absorption part 21, the slope 14 is provided. The inclined surface 14 can catch the water discharged from the moisture absorption part 21 and collect it to the water outlet 15 provided at one end of the lower part of the box body 1 .

This embodiment corresponds to an example expressing Embodiment 3 more concretely. Therefore, in this embodiment, the effects described in Embodiment 3 can be obtained.

(Embodiment 6)

Dehumidifier 106 according to Embodiment 6 of the present invention will be described with reference to FIGS. 13 to 15 . A schematic cross-sectional view of dehumidifier 106 is shown in FIG. 13 . The dehumidifier 106 includes a housing 1 . The housing 1 has an air inlet 11 and an air inlet 31 at the top. The dehumidifier 106 includes a plurality of disk-shaped moisture absorbing parts 23 inside the housing 1 . As shown in FIG. 14, some moisture absorption part 23 is hold|maintained in the state overlapped so that mutual separation may be carried out although the center axis|shaft is made into a common center axis|shaft. That is, gap 10 is provided between moisture absorption parts 23 . FIG. 15 shows a partially enlarged cross-sectional view of one moisture absorption unit 23 . The moisture absorption portion 23 includes a flat base material 13 and the moisture absorption member 2 formed on the surface thereof. Here, the example in which the moisture absorbing member 2 is formed on the upper surface of the base material 13 is shown, but the moisture absorbing member 2 may be formed not on the upper surface of the base material 13 but on the lower surface of the base material 13 . The hygroscopic member 2 may be formed on both upper and lower surfaces of the base material 13 .

As shown in FIG. 13 , dehumidifier 106 includes motor 16 that rotates multiple moisture absorbing units 23 together in housing 1 . The motor 16 and the some moisture absorption part 23 are connected by the rotating shaft.

The air 3 taken in from the air inlet 11 and entered into the housing 1 through the external air supply part 4 hits the moisture absorbing part 23 . The air 3 entering the box 1 goes to the air outlet 12 . At this time, at least a part of the air 3 goes to the air outlet 12 after passing through the gap 10 between the moisture absorption parts 23 . The air 3 is dehumidified by passing through the gap 10 between the moisture absorption parts 23 . The dehumidified air is discharged as air 6 from the side air outlet 12 .

Stimulus imparting unit 5 is disposed on the upper portion of the inner space of housing 1 . Stimulus imparting unit 5 includes blower fan 17 and heater 18 . The blower fan 17 and the heater 18 operate, and the hot air hits the moisture absorption part 23 by this. In the some moisture absorption part 23, it receives thermal stimulation by encountering hot air, and discharges water. At this time, the plurality of moisture absorbing parts 23 are rotated by the motor 16, and the liquid water adhering to the surface of the moisture absorbing parts 23 is thrown to the outside of the moisture absorbing parts 23 by centrifugal force. The water thrown off from the moisture absorbing portion 23 falls downward in the housing 1 .

Below the moisture absorption part 21, the slope 14 is provided. The inclined surface 14 can catch the water discharged from the moisture absorbing part 23 and dropped due to the centrifugal force, and collect it into the water outlet 15 provided at one end of the lower part of the box body 1 .

In this embodiment, since some moisture absorption part 23 is the state overlapped so that it may mutually space|interval, many surface areas can be ensured, and dehumidification can be performed efficiently. In addition, in the present embodiment, the discharged water can be efficiently removed by using the centrifugal force.

Moreover, in Embodiment 2-6, it is preferable that the moisture absorption member 2 contains N-isopropylacrylamide. With the above configuration, the moisture-absorbing member 2 can easily realize a configuration capable of alternately switching between the first state capable of absorbing moisture due to stimulation such as heat and the second state releasing the absorbed moisture.

In addition, as long as temperature-sensitive polymers such as poly(N-isopropylacrylamide) (PNIPAM) and its derivatives or polyvinyl ether and its derivatives are used as materials in the moisture absorbent, it is desirable to prepare and use them. The nature of the polymer hygroscopic components can be.

In addition, in this embodiment, the some moisture absorption part 23 is arrange|positioned so that the central axis may become a vertical direction, but the installation direction of the some moisture absorption part 23 is not limited to this.

In addition, in this embodiment, a combination of blower fan 17 and heater 18 is used as stimulus imparting unit 5 , but the stimulus imparting unit may be a surface heater or a wire heater embedded in base material 13 . In this case, the moisture absorption part 23 can be directly heated through the base material 13.

In addition, in this embodiment, the rotation speed of the moisture absorption part 23 may be reduced at the time of moisture absorption, and may be increased at the time of water discharge. Accordingly, water is sufficiently absorbed by the moisture-absorbing member during moisture absorption, and centrifugal force can be increased when water is discharged, so that water can be discharged in a short time.

In addition, a plurality of the above-mentioned embodiments may be used in combination as appropriate.

In addition, it is considered that the present invention can be used as a humidifier or a water generator in addition to a dehumidifier.

When using it as a humidifier, what is necessary is just to set it as the reverse operation|movement with a dehumidifier. For example, water in a liquid state is brought into contact with the hygroscopic member 2 as the first state, the hygroscopic member 2 absorbs moisture, and the stimulus applied to the hygroscopic member 2 is eliminated to change from the first state to the second state. The absorbent element 2 is discharged. In this state, the air flow is passed to contact the wet absorbent member 2 . This imparts moisture to the gas flow.

When used as a water generator, the surrounding air is brought into contact with the hygroscopic member 2, thereby absorbing the moisture in the air to the hygroscopic member 2, stimulating the hygroscopic member 2 in this state, and discharging the liquid state from the hygroscopic member 2 of water. Water discharged from the moisture-absorbing member 2 is collected in a container. In this way, liquid water can be obtained even in places where there is no water source such as a well and where it does not rain.

It is difficult for microorganisms to survive in the ionic moisture taken into the moisture-absorbing member. And since the moisture accumulated in the moisture absorbing member is stimulated by heat at 50 to 60° C. during drainage, a sterilizing effect due to the high temperature can be expected. However, in order to use the obtained water for drinking or standby drinking (domestic water such as clean water), it is also preferable to use a filter that can filter bacteria by sterilizing by irradiating UV light in consideration of the contamination of bacteria in the path after drainage, etc. combine.

For example, as shown in FIG. 16, it is possible to make the air flow pass through the moisture-absorbing part 22 formed by overlapping granular, layered or block-shaped moisture-absorbing members to absorb moisture, and then irradiate UV light and filters to make the moisture absorbed by stimuli such as heat. The discharged water is further purified for drinking or standby drinking. The above-mentioned water generator can also be realized using any one of the configurations of the dehumidifiers shown in Embodiments 1 to 6.

In addition, the said embodiment disclosed this time is an illustration and non-restrictive content in all points. The scope of the present invention is shown not by the above description but by the claims, and it is intended that all modifications within the meaning and range equivalent to the claims are included.
