[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dehumidifier that removes moisture in indoor air, and relates to a dry dehumidifier using a hygroscopic body.
[0002]
[Prior art]
FIG. 23 is a schematic view showing a conventional dehumidifier. Indoor air is taken into the dehumidifier 1 through the moisture absorption path 7 by the blower 4 as moisture-absorbing air, and the condenser 3 is cooled through one passage 3a of the condenser 3 having two paths. Thereafter, it passes through a hygroscopic part 2a of a hygroscopic device 2 having a rotating body (not shown) filled with a hygroscopic material such as zeolite and is absorbed by the hygroscopic material and released outside the dehumidifier 1. In addition, the regeneration air taken into the dehumidifier 1 through the regeneration path 8 by the blower 6 is heated by the heater 5 and passes through the regeneration unit 2 b of the moisture absorber 2 to raise the temperature of the moisture absorber containing moisture. Then, the moisture removed from the hygroscopic body is taken to regenerate the hygroscopic body.
[0003]
The regenerated hygroscopic material moves to the hygroscopic portion 2a by the rotation of the hygroscopic device 2 in the direction of arrow A, and absorbs moisture from the hygroscopic air passing through the hygroscopic path 7 again. The high-temperature and high-humidity regeneration air that has taken moisture from the hygroscopic body and passed through the hygroscopic device 2 is cooled by the aforementioned hygroscopic air through the other passage 3 b of the condenser 3. The moisture contained in the regeneration air is condensed and stored in the water storage tank 10, and the regeneration air is discharged outside the dehumidifier 1. Further, as shown in FIG. 24, there is a case where a closed circuit is formed so that the regeneration air after passing through the condenser 3 is put into the heater 5 and only the regeneration air is replenished from the outside.
[0004]
As shown in a side view of FIG. 25, the hygroscopic device 2 is configured such that a rotating body 21 provided in an outer frame 28 is connected to a motor 25 by a belt 26 and supported by a bearing 27 to rotate. The rotating body 21 is covered with a support frame 24 and is hollow, and a hygroscopic body 22 is filled therein. The regeneration air in the regeneration path 8 is formed to pass through the regeneration unit 2b (see FIG. 23) in the direction of arrow B.
[0005]
Further, the heater 5 is disposed close to the hygroscopic device 2 in the regeneration path 8, and when a top view and a front view are shown in FIGS. It is aligned facing 2b.

[Problems to be solved by the invention]
  In the dehumidifier having such a configuration, the regeneration path after passing through the condenser 3 in FIGS.8Since the dew point has been reached, dew condensation is likely to occur and water droplet recovery means and mold prevention measures are required to prevent water leakage, which has been a factor in increasing costs. Also, the heat of the heater 5 is released into the room together with the heat of adsorption when moisture in the air is adsorbed by the moisture absorber 22 (see FIG. 25) and the heat of condensation when moisture in the regeneration path is condensed by the condenser 3. As a result, the user may feel uncomfortable.
[0008]
In the regeneration unit 2b of the hygroscopic device 2 shown in FIGS. 23 and 24, the regeneration air heated by the heater 5 passes through the entire regeneration unit 2b uniformly. The hygroscopic body 22 (see FIG. 25) is heated by the regeneration air passing therethrough to release moisture, and the regeneration air absorbs the moisture and is sent from the moisture absorber 2 to the condenser 3.
[0009]
The moisture absorbing body 22 that has released the moisture moves from the heat receiving area (reproducing section 2b) to the heat radiating area (moisture absorbing section 2a) as the rotating body 21 (see FIG. 25) rotates. At this time, since the hygroscopic body 22 has already been heated by the regenerating air heated by the heater 5, the hygroscopic body 22 also has a high temperature in the vicinity of the regenerating section 2b even in the heat radiation area (the hygroscopic section 2a). There was room for effective use of the heat released while the indoor air was raised by the working air to raise the indoor temperature.
[0010]
Moreover, since the amount of regeneration air is larger in the outer peripheral portion 103 (see FIG. 26) of the regenerating portion 2b in the moisture absorber 2 than in the inner peripheral portion 104 (see FIG. 26), the heater arranged facing the regenerating portion 2b. When the five electric heating elements 5a are uniformly formed, the temperature of the outer peripheral portion 103 is lower than that of the inner peripheral portion 104. For this reason, the regeneration air causes a temperature difference between the outer peripheral portion 103 and the inner peripheral portion 104, so that the regeneration efficiency is deteriorated, and the temperature of the heater 5 is unnecessarily high to increase the regeneration efficiency. I was consuming.
[0011]
In FIG. 26, the regeneration air heated by the electric heater 5a of the heater 5 enters the regeneration unit 2b, and the heated regeneration air passes through the moisture absorber 22 (see FIG. 25), so that the moisture absorber 22 rises. Removes moisture contained by heating. The temperature of the regeneration air behind the electric heating element 5a and the temperature of the regeneration air behind the gap 5b between the electric heating elements 5a are different because the manner of contact of the regeneration air contacting the electric heating element 5a is different, A temperature difference occurs.
[0012]
Since the electric heating element 5a is arranged substantially along the circumferential direction of the hygroscopic device 2, even if the rotating body 21 (see FIG. 25) rotates, any point in the rotating body 21 is the same as that of the heater 5. The positional relationship (for example, the point behind the electric heating element 5a is located behind the electric heating element 5a in the same manner even when the rotating body 21 rotates), and the manner of contact between the electric heating element 5a and the regenerating air changes significantly. do not do. For this reason, a temperature difference arises in the temperature of the reproduction | regeneration air which enters into the moisture absorption body 22 in the reproduction | regeneration part 2b. Therefore, the regeneration efficiency in the regeneration unit 2b is deteriorated due to the temperature difference of the regeneration air, and the temperature of the regeneration unit 2b is higher than necessary in order to increase the regeneration efficiency.
[0013]
Since the condenser 3 is made of metal, the weight is heavy, and when the shape is biased, rust is generated due to condensed water, holes are formed, and water leaks occur. . Further, as shown in FIG. 25, the hygroscopic device 2 expands and contracts by the heated regeneration air and the radiant heat of the heater 5 disposed close thereto. The support frame 24 of the rotating body 21 that rotates inside the moisture absorbent 2 is thermally deformed due to expansion and contraction due to heat, causing a failure such as contact with the outer frame 28 and the rotating body 21 not rotating.
[0014]
An object of the present invention is to provide a dehumidifier capable of improving the temperature rising efficiency to reduce power consumption and suppressing a rise in room temperature to obtain a comfortable environment.
[0015]
It is another object of the present invention to provide a highly reliable dehumidifier that saves space and weight, reduces costs, easily realizes rust prevention, corrosion prevention, and bacterial growth prevention.
[0038]
[Means for Solving the Problems]
  In order to achieve the above object, a dehumidifier according to the present invention includes first and second regions having different humidity, and a rotating body that is filled with a moisture absorbent that absorbs moisture and rotates to pass through the first and second regions. A moisture absorber consisting of
  A moisture absorption path through which moisture absorption air that passes through the first region and moisture is absorbed by the moisture absorbent body;
  A regeneration path that passes through the second region and through which regeneration air that takes moisture from the hygroscopic body passes,
  A heater that heats the regeneration air so that the regeneration air put in the moisture absorber uniformly raises the temperature of the second region of the moisture absorber;
  A condenser that condenses and discharges the moisture of the regeneration air that has passed through the moisture absorber;
Made ofThe heater is arranged to face the fan-shaped surface forming the second region of the hygroscopic device and is formed of a curved electric heater that extends in the circumferential direction of the fan-shaped surface and is bent. A portion having a length of 1/2 or more is inclined with respect to a center line that bisects the fan-shaped surface.It is characterized by that.
[0039]
  According to this configuration, the heater heats the regeneration air passing through the second region so that the temperature of the second region of the moisture absorber is uniformly increased.In addition, an electric heating element arranged so as not to be orthogonal to the center line of the fan-shaped surface forming the second region heats the regeneration air, and passes through the second region of the hygroscopic device facing the heater, at any one point of the rotating body Rotates alternately behind the electric heaters and the gaps between the electric heaters.
[0041]
  The electric heating element isA row formed in a substantially fan-shaped planar shape that is bent so as to face the fan-shaped surface.A plurality of rows are arranged in parallel in a direction perpendicular to the fan-shaped surface, and in two adjacent rowsThe electric heating element with respect to a center line that bisects the fan-shaped surfaceIt is characterized by different inclination angles. According to this configuration, the electric heaters arranged in a plurality of rows in the traveling direction of the regeneration air have different inclination directions for each row, and the hygroscopic member rotates behind the electric heater arranged in a mesh shape and rises uniformly. It has come to be heated.
[0047]
DETAILED DESCRIPTION OF THE INVENTION
  Embodiment of the present inventionReference form for the present inventionWill be described with reference to the drawings. 1 to 22, the same members as those in the conventional example are denoted by the same reference numerals. 1 is the firstreference1 shows a schematic diagram of a dehumidifier in form. The difference from the conventional example (see FIG. 23) is that a heat exchanger 9 is provided for exchanging heat between the hot and humid regeneration air that has passed through the moisture absorber 2 and the regeneration air that has passed through the condenser 3. Yes.
[0048]
In such a configuration, the regeneration path 8 passes through the condenser 3 and reaches the dew point in the dehumidifier 1 having an open circuit so that the regeneration air after passing through the condenser 3 is released into the room. The temperature of the air is raised by exchanging heat with the high-temperature and high-humidity regeneration air that has passed through the moisture absorber 2 to prevent condensation on the regeneration path 8 c after the heat exchanger 9.
[0049]
  2 is the secondreference1 shows a schematic diagram of a dehumidifier in form. According to the figure, the first case where the regeneration path 8 in which the regeneration air after passing through the condenser 3 enters the heater 5 is a closed circuit is shown in FIG.referenceThe configuration is the same as that of the form (see FIG. 1). With this configuration, the firstreferenceAs in the embodiment, condensation in the regeneration path 8c after the heat exchanger 9 can be prevented, and regeneration air entering the heater 5 (regeneration path 8).c) Can be raised in advance, so that the power consumption of the heater 5 can be reduced.
[0050]
In addition, an open circuit is adopted in which the regeneration air (regeneration path 8 b) entering the heat exchanger 9 is taken from the room and the regeneration air (regeneration path 8 c) after passing through the condenser 3 is discharged out of the dehumidifier 1. In some cases, the power consumption of the heater 5 can be reduced as described above.
[0051]
  Then the thirdreferenceThe form dehumidifier is demonstrated with reference to FIG. According to the drawing, in the recovery unit 2bb adjacent to the regeneration unit 2b of the moisture absorber 2 and in the front of the rotation body 21 (see FIG. 25) in the moisture absorber 2, the moisture absorber 22 ( 25) is still rotated while maintaining the high temperature state. A branch path 7 a that branches from the moisture absorption path 7 is provided so as to pass through the recovery section 2 bb, and the heat of the recovery section 2 bb is recovered by moisture absorption air passing through the branch path 7 a and before entering the heater 5 by the heat exchanger 9. Exchanging heat with the regenerative air.
[0052]
  With this configuration, the secondreferenceAs in the embodiment, the regeneration air entering the heater 5 can be heated in advance, so that the power consumption of the heater can be reduced. Furthermore, the moisture absorption body 22 is cooled by moisture absorption air passing through the branch path 7a before the moisture absorption body 22 enters the moisture absorption section 2a with the rotation of the rotating body 21, and the moisture absorption efficiency in the moisture absorption section 2a can be improved.
[0053]
At this time, the hygroscopic air passing through the branch path 7a which has become high temperature is recovered by the heat exchanger 9, so that it becomes low temperature and is released outside the dehumidifier 1 so that the room temperature is not raised. Here, a part of the moisture in the hygroscopic body 22 is released to the outside of the dehumidifier 1 by the hygroscopic air passing through the branch path 7a. However, the indoor humidity is increased by reducing the flow rate in the branch path 7a. The temperature of the hygroscopic body can be lowered without causing it to fall.
[0054]
  4threferenceThe form dehumidifier is demonstrated with reference to FIG. According to the figure, the thirdreferenceAlthough the configuration is the same as the configuration (see FIG. 3), the rotation direction of the rotating body 21 (see FIG. 25) in the moisture absorber 2 can be selected from forward rotation (arrow A) and reverse rotation (arrow A ′). ing. In this way, when the rotating body 21 is rotated forward in the direction of arrow A, the thirdreferenceThe same effect as the form can be obtained.
[0055]
  When the rotating body 21 is reversed in the direction of the arrow A ′, the recovery portion 2bb through which the branch path 7a passes is at a low temperature. Therefore, the branch path 7a and the moisture absorption path 7 are one moisture absorption path similar to the conventional example (see FIG. 24). 7 can be considered. At this time, a high temperature in front of the rotation direction (arrow A ′) of the rotating body 21 with respect to the reproducing unit 2b.PartThe relatively high-temperature dry moisture-absorbing air that passes through is discharged out of the dehumidifier 1 as in the conventional example. Since the clothes can be dried using this high-temperature dry air, the user can selectively use the dehumidification priority or clothes drying by selecting the rotation direction of the rotating body 21.
[0056]
  Next, fifthreferenceThe form dehumidifier is demonstrated with reference to FIG. According to the figure, the thirdreferenceThe blower 12 is provided in the branch path 7a of the form (see FIG. 3). With this configuration, moisture absorption through the branch path 7a is performed so that the moisture absorption air passing through the branch path 7a is absorbed from the hygroscopic body and the amount of moisture released to the outside of the dehumidifier 1 is not increased to deteriorate the dehumidification performance. The flow rate of working air can be set optimally.
[0057]
  6threferenceThe form dehumidifier is demonstrated with reference to FIG. According to the figure, a dew condensation prevention heater 17 is provided on the regeneration path 8 after passing through the condenser 3 to prevent condensation on the regeneration path 8c through which the regeneration air cooled to the dew point and has reached the dew point is passed. To be able to.
[0058]
  Then the seventhreferenceThe form dehumidifier is demonstrated with reference to FIG. According to the figure, a branch path 7b branched from the moisture absorption path 7 so as not to pass through the moisture absorber 2 is provided. If it does in this way, the flow volume of the moisture absorption air which passes through the condenser 3 can be increased, and the efficiency of condensation can be improved. When a predetermined amount or more of hygroscopic air is passed through the hygroscopic device 2, the hygroscopic capacity of the hygroscopic body 22 (see FIG. 25) decreases, so that the predetermined amount or more of the hygroscopic air is dehumidified without passing through the hygroscopic device 2 through the branch path 7 b. It is discharged outside the machine 1.
[0059]
In order to allow a predetermined amount of hygroscopic air to pass through the hygroscopic device 2, a restricting plate 32 is arranged to shield the hygroscopic air entering the hygroscopic device 2 in the hygroscopic path 7 as shown in the detailed view of the main part of FIG. 8. The limiting plate 32 has a through hole 32a. In this way, the amount of air passing through the restriction plate 32 becomes constant, and the flow of air entering the hygroscopic device 2 becomes uniform, improving the moisture absorption efficiency. Similarly, a restriction plate 43 having a through hole 43a may be installed between the heater 5 and the hygroscopic device 2 in the regeneration path 8, and the air flow of regeneration air entering the regeneration unit 2b is made uniform. Thus, the temperature of the hygroscopic body 22 can be increased uniformly.
[0060]
  Next is the eighthreferenceA form is demonstrated with reference to FIG. 9, FIG. (A), (b) and (c) in FIG.referenceThe top view, the front view, and the side view of the condenser 3 of the form are shown, and FIG. 10 is a schematic perspective view which shows the D section in FIG. According to these figures, the high-temperature and high-humidity regeneration air flowing into the condenser 3 from the air inlet 37 provided above the condenser 3 is a plurality of condensation passages 34 ( Branches to the first passage) and proceeds downward.
[0061]
A through-hole 36 is provided between adjacent condensing passages 34, and the low-temperature moisture-absorbing air passes perpendicularly to the surface 3d as indicated by the arrow F and exchanges heat with the regeneration air to regenerate air. The water inside is condensed. The dried regeneration air is sent out from an air outlet 38 provided in the lower part of the condenser 3, and the condensed water flows down through the condensation passage 34 and is discharged from the outlet 39.
[0062]
The air outlet 38 is provided at a position not in contact with the lower end surface 40 b so that the condensed water flowing down the lower end surface 40 b does not leak from the air outlet 38. A guide surface 40a is provided so as to guide the regenerating air that passes through each condensing passage 34 and joins to the air outlet 38. The guide surface 40a prevents the regeneration air from leaking from the discharge port 39, and the condensed water drops on the lower end surface 40b from a hole (not shown) provided in the guide surface 40a while flowing down the inclined guide surface 40a. It is like that. A passage 35 (second passage) formed so as to be connected across the condensing passages 34 is provided in order to make the pressure of each condensing passage 34 uniform.
[0063]
Such a condenser 3 is formed of a resin, and as shown schematically in FIG. 11, a blow molding process for molding a resin 42 such as polypropylene with a mold 41 while feeding air into the interior as indicated by an arrow G. Then, the through-hole 36 can be easily formed by punching by Thomson processing or the like. Therefore, the weight of the dehumidifier body is reduced compared with the conventional metal condenser, and the carrying of the dehumidifier body is facilitated, and the material cost and the processing cost can be reduced. Further, since rust does not occur, the cause of failure such as water leaking from the hole due to rust can be eliminated and the reliability can be improved.
[0064]
  In addition, since the heat conductivity is lower than that of a metal condenser, the condensation efficiency is lowered. However, the thickness t is reduced to 0.5 to 0.7 mm, and the cross-sectional shape of the condensing passage 34 is reduced in width. The condensing efficiency is improved by increasing the number of the condensing passages 34 by forming a long hole with a short direction (see H part in FIG. 9). BookreferenceIn the embodiment, the inner diameter of the condensing passage 34 is the width direction D = 8.6 mm, the thickness direction W = 20.6 mm, and the pitch in the width direction of the condensing passage 34 is P = 15 mm.
[0065]
Further, a plurality of condensers 3 may be arranged in parallel with the surface 3d so that the through holes 36 are not aligned on a straight line. In this way, after the low-temperature air from the direction of arrow F passes through the through hole 36 of the first condenser 3, a part of the air passes through the surface 3d of the second condenser 3 (condensation passage 34 portion). ) To generate a vortex, and after stopping for a short time, it passes through the through-hole 36 of the second condenser 3 and the substantial contact area with high-temperature air is increased, thereby improving the condensation efficiency.
[0066]
  Next is the ninthreferenceA form is demonstrated with reference to FIG. According to the figure, a primary water tank 10 for storing condensed water is provided andreferenceIt connects with the discharge port 39 of the condenser 3 of a form. A water level sensor 14 is installed in the primary water tank 10, and when a predetermined water level J is reached, the pump 11 sends water to a secondary water tank (not shown), and when the water level drops (water level W), the pump 11 is stopped. It has become.
[0067]
According to such a configuration, the condensed water is always accumulated and blocked in the discharge port 39 portion of the condenser 3, and the water surface can further prevent the regeneration air from leaking from the discharge port 39. It becomes like this. Further, when the water level J is disposed below the lower end 38a of the air outlet 38, the water level rises when the water level sensor 14 or the pump 11 breaks down, and the air outlet 38 is closed to flow out the regeneration air. The amount is reduced.
[0068]
As shown in the side view of FIG. 13, in the case of a closed circuit in which the regeneration air that has passed through the condenser 3 is introduced into the heater 5, the regeneration that exits the heater 5 when the flow rate of the regeneration air entering the heater 5 decreases. Since the temperature of the working air is higher than the predetermined temperature, it is possible to stop the operation of the dehumidifier 1 by detecting that the temperature of the regenerating air exiting the heater 5 is high by the temperature sensor 13 or the like. As a result, the water level sensor 14 and the pump 11 can be detected to prevent water leakage.
[0069]
  Eighth, ninthreferenceAlthough the form was demonstrated about the condenser 3, since it heat-exchanges with high temperature air and low temperature air, it is 1st thru | or 5th.referenceThe heat exchanger 9 as used in the embodiment can have the same configuration, and the same effect can be obtained.
[0070]
  10threferenceThe form will be described with reference to FIG. Figure 14 shows a bookreferenceIt is the schematic explaining the structure of the heater 5 of a form. According to the figure, the branched regeneration paths 8j and 8k pass through the first and second temperature raising passages 5c and 5d passing through the heater 5 and pass through the regeneration portions 2b1 and 2b2 of the moisture absorber 2. The hygroscopic body 22 (see FIG. 25) of the regenerating unit 2b1 of the hygroscopic device 2 is heated in advance through the regenerating unit 2b2 behind the rotating body 21 (see FIG. 25) rotating in the hygroscopic device 2. Therefore, it has residual heat and releases moisture. Therefore, the regeneration air passing through the regeneration path 8j can absorb the released moisture and regenerate the hygroscopic body 22 even at a lower temperature than the regeneration air passing through the regeneration path 8k.
[0071]
Therefore, the temperature of the regenerating air heated through the first temperature rising passage 5c is set to be lower than the temperature of the regenerating air heated through the second temperature rising passage 5d. Since the temperature of the hygroscopic body 22 that moves to the hygroscopic section 2a can be lowered with the rotation of the rotating body 21 in the A direction without causing the regenerating section 2b2 to be unnecessarily high, it is for moisture absorption through the hygroscopic path 7. The amount of heat released to the outside of the dehumidifier 1 by air can be suppressed, and power consumption can be reduced without using wasted power.
[0072]
In addition, the regeneration air passing through the first temperature raising passage 5c may be configured not to rise in temperature, and in this case as well, the regeneration air is released from the hygroscopic body 22 heated by the regeneration air passing through the regeneration path 8k. Moisture is absorbed by the regeneration air passing through the regeneration path 8j, and before the hygroscopic body 22 of the regeneration unit 2b1 enters the hygroscopic unit 2a as the rotating body 21 rotates, the temperature of the hygroscopic body 22 is lowered to increase the hygroscopic capacity. Can be improved.
[0073]
  Next eleventhreferenceA form is demonstrated with reference to FIG. Figure 15 shows the bookreferenceIt is the schematic explaining the structure of the heater 5 of a form. According to the figure, the branched regeneration paths 8j and 8k pass through the regeneration parts 2b3 and 2b4 of the moisture absorber 2 through the inner peripheral part 5e and the outer peripheral part 5f of the heater 5. Since the regeneration unit 2b4 on the outer peripheral side has a larger amount of regeneration air than the regeneration unit 2b3 on the inner peripheral side, the density of the electric heating element 5a (see FIG. 26) constituting the heater 5 is set to the inner peripheral part 5e with respect to the outer peripheral part 5f. When the temperature of the regeneration air passing through the regeneration path 8j is made lower than the temperature of the regeneration air passing through the regeneration path 8k, the regeneration section 2b3 on the inner peripheral side does not become unnecessarily high, and the regeneration section 2b rotates. The temperature of the hygroscopic body 22 (see FIG. 25) passing through becomes uniform, and power consumption can be reduced without using wasted power.
[0074]
  Next1The embodiment will be described with reference to FIG. FIG. 16 is a front view showing the heater 5 of the present embodiment. The heater 5 is composed of an electric heating element 5a arranged so as to cover the regenerating part 2b of the hygroscopic device 2, and the electric heating element 5a does not cross more than 1/2 with respect to the center line J that bisects the reproducing part 2b. Is formed. In this way, when the rotating body 21 (see FIG. 25) rotates in the hygroscopic device 2 behind the heater 5, any point in the rotating body 21 is in the same manner as any contact point with the electric heating element 5a. Since the temperature is alternately raised to the regeneration air behind the electric heater 5a and the regeneration air behind the gap 5b, the hygroscopic body 22 of the regeneration unit 2b can be uniformly heated, and wasteful power can be used. Power consumption can be reduced.
[0075]
Here, when the length of the electric heating element 5a that is not orthogonal to the center line J is ½ or less of the entire length of the electric heating element 5a, the rotation of the rotating element 21 causes only the electric heating element 5a or the gap 5b behind. The number of rotational movements increases and the temperature of the reproducing unit 2b cannot be increased uniformly.
[0076]
  Further, in FIG.2As shown in the embodiment, when the electric heating elements 5a are arranged so as to be arranged in a plurality of rows in the inflow direction of the regeneration air, and the inclination angle of the electric heating elements 5a with respect to the center line J is different in each row, the reproduction unit 2b is more uniform. This is desirable because it allows a high temperature increase.
[0077]
  Next12 ReferenceThe form will be described with reference to FIG. BookreferenceIn the embodiment, the heater 5 (see FIG. 26) is not required, and the moisture absorber is regenerated in the moisture absorber 2. According to FIG. 18 (a), when the heat-absorbing material 52 such as glass fiber is dipped in the moisture-absorbing body 53 such as zeolite and then pulled up and cooled, the fibrous moisture-absorbing body 54 in the form of fibers can be formed. it can.
[0078]
The fibrous hygroscopic body 54 is wound around the heating wire 51 and filled in the rotating body 21 (see FIG. 25) that rotates in the hygroscopic device 2, and the current is passed through the heating wire 51 to raise the temperature of the hygroscopic body 53 and moisture. Can be released. In this way, since the heater 5 is not necessary, the main body of the dehumidifier 1 can be downsized. Further, as shown in (b), the fibrous hygroscopic body 54 may be knitted in a net shape so as to cover the heating wire 51.
[0079]
As shown in a schematic perspective view and a side view of the rotator 21 in FIGS. 19A and 19B, the rotator 21 is divided into a plurality of blocks 21a to 21f, and the fibrous moisture absorber 54 filled in each block. The heating wire 51 covered with (see FIG. 18) is connected to a terminal 51a whose one end is fixed to the rotating body 21, and the terminal 51a is rotated when each block rotates and passes through the reproducing unit 2b (see FIG. 1). Is configured to come into contact with the electrode 31 provided on the bearing 27 part, the temperature of the hygroscopic body 53 can be raised only when the hygroscopic body 53 (see FIG. 18) passes through the regenerating part 2b.
[0080]
  Furthermore, in FIG.13 ReferenceAs shown in the embodiment, when the integral member 55 in which the heating wire 51 is covered with the fibrous moisture absorber 54 is integrated with the flexible member 56 in a band shape, the density of the moisture absorber 53 is formed to a desired density and installed in the moisture absorber 2. Will be able to.
[0081]
  Next14 ReferenceA form is demonstrated with reference to FIG. Figure 21 shows the bookreferenceIt is a front view which shows the support frame 24 of the rotary body 21 (refer FIG. 25) in a form. According to the figure, lattice holes 24c are formed by concentric ribs 24a and radial ribs 24b so that the regeneration air or moisture absorption air can pass therethrough. Here, the radial ribs 24b that connect the three adjacent concentric ribs 24a are not formed on a straight line but are shifted.
[0082]
In such a support frame 24, when the moisture absorption body 22 (refer to FIG. 25) inside the rotating body 21 is thermally expanded when the temperature is raised, a schematic view of FIG. 22 shows concentric ribs 24a, The expansion amount of the radial ribs 24b is absorbed in each lattice hole 24c. The outer diameter of the support frame 24 is increased by the length of thermal expansion of the outermost radial ribs 24b and the outermost concentric ribs 24a, and the thermal expansion is reduced compared to the case where the radial ribs are provided on a straight line. be able to. Thus, even if the moisture absorber 22 repeats heating and cooling, even if the support frame 24 is repeatedly expanded and contracted, the amount of deformation remains and the contact with the outer frame 28 (see FIG. 25) is prevented. Reliability can be improved.
