Description

  The present invention relates to a dehumidifying device provided with a rotary adsorbent (adsorption rotor).

  In recent years, in a dehumidifier equipped with a rotary adsorbent (adsorption rotor) mainly used in general homes, the air used for regeneration of the adsorbent is circulated to a high dew point state, and the air in the high dew point state is moved indoors. It is common to perform dehumidification by cooling with air and condensing and collecting it as condensed water (see, for example, Patent Document 1).

  Hereinafter, a conventional dehumidifier will be described with reference to FIG.

  FIG. 8 is a simplified cross-sectional view showing the configuration of a conventional dehumidifier that circulates air used for regeneration and collects it as condensed water. As shown in FIG. In the main body 101, moisture is absorbed from the first air 102 in the moisture absorption region 105, and in the regeneration region 106, the moisture is released to the second air 108 heated by the heating means 107. An adsorbent 109 to be regenerated, a driving means 110 for rotating the adsorbent 109 so that moisture absorption from the first air 102 in the moisture absorption region 105 and moisture release to the second air 108 in the regeneration region 106 are repeatedly performed; The second air 108 that has flowed out of the region 106 is cooled by the first air 102 and the moisture from the adsorbent 109 is recovered as condensed water, and the first air is discharged from the suction port 103. A first air supply means 112 that sucks 102 and supplies it to the moisture absorption area 105 and the condenser 111; and a second air supply means 113 that circulates the second air 108 in the order of the heating means 107, the regeneration area 106, and the condenser 111. I have.

  The operation of the dehumidifier configured as described above will be described. The first air 102 is sucked from the suction port 103 by the first air supply means 112 and supplied to the condenser 111 to cool and dehumidify the second air 108. Thereafter, the moisture is supplied to the moisture absorption region 105. In the moisture absorption region 105, the first air 102 is absorbed by the adsorbent 109 to become dry air, and is blown out of the apparatus from the blowout port 104. On the other hand, the second air 108 circulated by the second air supply means 113 is heated by the heating means 107 and is supplied to the regeneration region 106 at a high temperature. The second air 108, which contains the moisture dehumidified from the adsorbent 109 by heating and regenerating the adsorbent 109 in the regeneration region 106, is supplied to the condenser 111, and is cooled below the dew point temperature by the first air 102. Is done. The second air 108 cooled and dehumidified in the condenser 111 is sucked into the second air supply means 113 and the above operation is repeated. By this circulation, the second air 108 maintains a dew point higher than the temperature of the first air 102, and condensation in the condenser 111 is promoted. Moisture in the second air 108 condensed by the condenser 111 is drained to the outside from the condenser drain port 114. The amount of the dewed condensed water corresponds to the dehumidifying amount of the dehumidifying device. Further, since there is a limit to the amount of moisture absorbed by the adsorbent 109, the adsorbent 109 is rotated and moved by the driving means 110 so that the adsorbent 109 is not saturated, and the hygroscopic area 105 absorbs moisture from the first air 102 and the regeneration area 106. The second air 108 is repeatedly dehumidified to enable continuous dehumidification operation for a long time.

  In addition, as a method of partitioning the first air 102 flowing into the moisture absorption region 105 of the adsorbent 109 and the first air 102 flowing out of the moisture absorption region 105, a partition plate 115 that pivotally supports the adsorbent 109 by the driving means 110. There was a partition structure (see, for example, Patent Document 2).

FIG. 9 is an explanatory diagram of a configuration showing the attachment state of the partition plate 115 and the adsorbent 109 when the partition plate 115 in the conventional dehumidifying device is viewed from the rear stage side in the passage direction of the first air 102. As shown in FIG. 9, the adsorbent 109 is accommodated in the adsorbent holding means 116 and forms a rotatable cylindrical adsorbent rotor 117. The partition plate 115 is fitted in the boss 120 of the suction rotor 117 positioned at the center of the opening 119 and the opening 119 having substantially the same outer dimensions of the suction material opened in the cylindrical folder 118 that houses the suction rotor 117. A rotation shaft 121 that is an axis when the suction rotor 117 rotates, and ribs 122a, 122b, 122c, 122d, and 122e that maintain the strength of the partition plate 115 by bridging outward from the rotation shaft 121 are provided. The ribs 122a and 122c are arranged in the vertical direction, and the ribs 122b and 122d are arranged in the horizontal direction. The rib 122a is bridged toward the top surface of the main body, the rib 122c is bridged toward the bottom surface of the main body, and the rib 122e is bridged at an angle θ with respect to the rib 122a. This angle θ defines the ratio of the reproduction area 106 to the entire adsorbent 109. Then, the fan-shaped portion having an angle θ between the rib 122a and the rib 122e corresponding to the regeneration region 106 is protruded in the direction opposite to the insertion side of the adsorbent 109, and the second air that has become highly humid in the regeneration region 106 A regeneration chamber 123 for uniforming the temperature and humidity of 108 is formed. Thus, the regeneration chamber 123 is formed integrally with the partition plate 115. And the condenser connection part 124 which connects the condenser 111 to the regeneration chamber 123 is provided, and the condenser 111 is connected. The drive means 110 is composed of a drive motor 125 and a drive gear 126 fastened to the shaft of the drive motor 125, and a rotor gear 127 for rotationally driving the suction rotor 117 is attached to the suction rotor 117. 116 is provided along the outer periphery of 116. Then, when the drive gear 126 is engaged with the rotor gear 127 and is rotated by the drive motor 125, the suction rotor 117 can be driven to rotate.

A rotor frame B11 is fitted along the outer periphery on the opposite end side of the rotor frame A10, and is fixed to the rotor frame A10 by screwing a plurality of locations. A boss receiving portion 13 is provided at the center of the rotor frame B11, and the frame ribs 14 are bridged radially from the boss receiving portion 13 so that the boss 120 that fits in the central shaft hole of the adsorbent 109 from the opposite side of the rotor frame B11 is received by the boss receiving. By fixing the portion 13 with screws, the relative position between the rotor frame A10 and the boss 120 is defined, and the adsorbent 109 is protected and held. Each frame rib 14 is bridged by a ring portion 15 to maintain strength. One or more ring portions 15 may be provided. If the diameter of the adsorbent 109 is large, a plurality of ring portions 15 are preferably provided. In addition, a rotor gear 127 for enabling rotation of the suction rotor 117 is formed on the outer periphery of the rotor frame A10 by integral molding with the rotor frame A10 and the stopper 12. Since the rotor frame B11 is rustproof and requires a high strength with a thin plate thickness, a stainless steel plate having a plate thickness of 0.4 to 1.0 mm, preferably 0.4 mm, is manufactured by pressing and bending. Used.

  As shown in detail in FIGS. 2B and 2C, the shielding means 16 shields leakage of the first air 102 from the gap between the outer periphery of the adsorption rotor 117 and the opening 119 of the partition plate 115. The shielding wall 17 is arranged over the entire outer periphery of the rotor frame B11. The shielding wall 17 protrudes from the rotor frame B11 so as to cover the opening 19 of the gear teeth 18 of the rotor gear 127, and is formed integrally with the rotor frame B11. The shielding wall 17 is configured by providing a disk-like wall having substantially the same diameter as the outer peripheral diameter P of the rotor gear 127 over the entire outer periphery of the rotor frame B11, as viewed from the inflow direction of the first air 102 of the adsorbent 109. In this case, the gear teeth 18 and the opening portion 19 of the rotor gear 127 are arranged so as to be completely hidden. The operation and effect of the shielding means 16 will be described below. In the present embodiment, the shielding wall 17 is formed integrally with the rotor frame B11, and it is economical because it is not necessary to add any components or the like.

  FIG. 3A is an exploded view showing the attachment state of the suction rotor 117 and the heating means 107 to the partition plate 115, and FIG. 3B is a schematic sectional view taken along the line CC in FIG. 3A. FIG. 3 (c) shows an enlarged view of a portion D in FIG. 3 (b).

  The heating means 107 is configured by inserting a heater 21 into a fan-shaped heater case 20 and covering with a heater lid 22. The heater case 20 is provided with an inflow portion 23 for the second air 108, and second air supply means 113 (shown in FIG. 1) is connected to the inflow portion 23. The heater lid 22 has an outflow portion 24 for the second air 108 opened. The partition plate 115 includes a cylindrical folder 118 that houses the adsorption rotor 117, and the folder 118 is provided with an opening 119 through which the first air 102 passes. A regeneration chamber 123 formed in a fan-shaped box shape is fixed to the partition plate 115 by screwing a plurality of fan-shaped outer peripheral portions to the partition plate 115. The regeneration chamber 123 includes a condenser connection portion 124 for connecting a condenser 111 (shown in FIG. 1), a regeneration region 106 for the adsorbent 109, and an adsorbent partition portion 25 for separating the moisture absorption region. As shown in FIG. 1, the condenser 111 has the inlet pipe 3 and the outlet pipe 4 arranged below the condenser 111, and the air path of the second air 108 is turned above the condenser 111. In order to increase the area, it is advantageous to dispose the inlet pipe 3 and the outlet pipe 4 as downward as possible. For this reason, the condenser connection part 124 is disposed as downward as possible in the regeneration chamber 123. Further, the adsorbent partitioning section 25 divides the moisture absorption area 105 and the regeneration area 106 of the adsorbent 109 and includes an adsorbent facing surface 26. The adsorbent facing surface 26 is disposed so as to face the adsorbent 109, and is further disposed so as to face the heater seal portion 27 provided on the heater lid 22 of the heating means 107. Mixing of the first air 102 passing through and the second air 108 passing through the regeneration region 106 is suppressed. The end of the adsorbent facing surface 26 is chamfered so that the rotor frame B11 is not caught when the adsorption rotor 117 rotates. Also, since the second air that has passed through the regeneration region 106 may be at a relatively high temperature (about 80 degrees or more), it is preferable that the regeneration chamber has heat resistance. Molded with a compatible resin material. In this case, the heat distortion temperature may be 200 ° C. or higher, and it is molded from a heat resistant material such as PPS resin having a heat deformation temperature of 260 ° C. or higher, or glass fiber reinforced PET resin having a heat deformation temperature of 200 ° C. or higher. ing. It should be noted that if the gap between the adsorbent facing surface 26 and the end face of the adsorbent 109 and the gap between the heater seal portion 27 and the end face of the adsorbent 109 are reduced, the sealing performance can be ensured. The surface 26, the heater seal portion 27, and the adsorbent 109 may be touched and damaged due to manufacturing errors. For this reason, the gap between the adsorbent facing surface 26 and the end face of the adsorbent 109 is preferably 0.6 mm to 1.0 mm, preferably 0.7 mm or less, taking into consideration that the rotor frame B11 is interposed. Further, the gap between the heater seal portion 27 and the end face of the adsorbent 109 is preferably 0.2 mm to 0.5 mm, and preferably 0.3 mm or less.

  A rotation shaft 121 for pivotally mounting the suction rotor 117 is formed at the fan-shaped central portion of the regeneration chamber 123, and the rotation shaft 121 also serves as the central portion of the opening 119 of the partition plate 115. Yes. The adsorption rotor 117 is accommodated in the folder 118 by fitting a boss 120 attached to the center of the adsorbent 109 into the rotation shaft 121 of the reproduction chamber 123. The adsorption rotor 117 is sandwiched by the heating means 107 so as not to fall off the rotation shaft 121, and the heater lid 22 and the regeneration chamber 123 of the heating means 107 are rotated by screwing the center of the rotation shaft 121 and the outer periphery of the adsorption rotor 117. Freely pivot.

  The drive unit 110 includes a drive motor 125 and a drive gear 126 fastened to the shaft of the drive motor 125, and partitions the drive motor 125 so that the drive gear 126 and the rotor gear 127 arranged on the outer periphery of the suction rotor 117 are engaged with each other. The plate 115 is fixed by screwing. The suction rotor 117 can be rotationally driven by the drive motor 125 rotating the drive gear 126 and causing the drive gear 126 to rotate while meshing with the rotor gear 127.

  The second air 108 supplied from the inflow portion 23 to the heating means 107 by the second air supply means 113 (shown in FIG. 1) is heated by the heater 21 and flows out from the outflow portion 24 of the heater lid 22 to a high temperature state. The high-temperature second air 108 that has flowed into the regeneration region 106 of the adsorbent 109 dehumidifies and regenerates the adsorbent 109, becomes a high humidity state, and flows out to the regeneration chamber 123. The second air 108 in a high humidity state is averaged in temperature and humidity by the regeneration chamber 123 and then guided to the condenser 111 (shown in FIG. 1) from the condenser connection part 124. On the other hand, the first air 102 passes through the vent hole 7 of the condenser 111 by the first air supply means 112 (illustrated in FIG. 1), cools the second air 108 flowing in the condenser 111, and then It is guided to the moisture absorption region 105 of the adsorbent 109 through the opening 119. In the moisture absorption region 105, moisture in the first air 102 is absorbed by the adsorbent 109, becomes dry air, flows out of the moisture absorption region 105, and is supplied into the room. Then, when the adsorption rotor 117 is driven to rotate by the driving means 110, moisture absorption and regeneration of the adsorbent 109 are continuously performed. In the above, when the first air 102 passes through the opening 119 of the partition plate 115 and does not pass through the moisture absorption region 105 of the adsorbent 109, so-called adsorbent 109 is bypassed, a part of the first air 102 is It will be supplied indoors without being dehumidified. Further, since the hygroscopic region 105 of the adsorbent 109 is not sufficiently absorbed by the moisture and rotates and moves to the regeneration region 106, the absolute humidity of the second air 108 after the regeneration does not sufficiently increase, and the condenser 111 is sufficiently Condensation is not possible and the dehumidification amount may decrease.

  As shown in FIG. 3B, the diameter Q of the opening 119 is the outer periphery of the adsorption rotor 117 as shielding means 16 for suppressing leakage of the first air 102 from the gap between the opening 119 of the partition plate 115 and the adsorption rotor 117. The partition plate 115 and the suction rotor 117 are installed close to each other so as to be smaller than the diameter R of the portion. Thereby, the outer peripheral seal portion 28 can be formed in a portion where the opening 119 of the partition plate 115 and the outer peripheral portion of the adsorption rotor 117 are close to each other, the bypass of the adsorbent 109 of the first air 102 is prevented, and the adsorbent 109 Decrease in the air volume of the first air 102 passing through the adsorption region 105 can be suppressed. If the gap S between the partition plate 115 and the suction rotor 117 is too small, contact may occur, and the frictional resistance may cause the rotational drive of the suction rotor 117 to stop abnormally. It becomes impossible to block the flow. In consideration of the above, the gap S is preferably 0.2 mm to 0.5 mm, and preferably 0.3 mm or less.

  Further, as shown in FIG. 3C, the inner wall of the folder 118 and the shielding wall 117 provided on the rotor frame B11 of the suction rotor 117 are disposed close to each other, and the folder 118 is disposed on the inner wall of the folder 118 and the outer peripheral portion of the shielding wall 17. The seal part 29 is formed. As described with reference to FIG. 2, the shielding wall 17 is configured to cover the opening portions 19 of the gear teeth 18 of the rotor gear 127 provided on the outer periphery of the suction rotor 117. Therefore, in the unlikely event that the rotating shaft 121 is inclined due to a manufacturing error or the like, even if the sealing performance at the outer peripheral seal portion 28 between the partition plate 115 and the suction rotor 117 described above cannot be ensured, the adsorbent 109 is removed. The shielding wall 17 can shield the first air 102 to be bypassed from passing through the opening 19 between the gear teeth 18 of the rotor gear 127. Further, the folder seal portion 29 between the folder 118 and the shielding wall 17 also prevents the first air 102 from bypassing the moisture absorption region 105 of the adsorbent 109. As described above, since the first air 102 can be prevented from bypassing the adsorbent 109, the shielding means 16 having higher sealing performance can be obtained. If the gap T between the inner wall of the folder 118 and the outer periphery of the shielding wall 17 is too small, it may come into contact and the rotational drive of the suction rotor 117 may stop abnormally. If it is too large, the air flow will be blocked. Will not be able to. In consideration of the above, the gap is preferably 1.5 mm to 2.0 mm, and preferably 1.5 mm.

Is provided. Even if the suction rotor 117 is tilted in the direction of the arrow in the drawing due to an error in manufacturing the rotating shaft 121, a part of the rotor gear 127 comes into contact with the suction rotor shake prevention wall 30 to cause the suction rotor. The inclination of 117 is minimized, and the sealing performance between the suction rotor 117 and the opening 119 of the partition plate 115 is not impaired. The drive gear 126 is always in contact with the rotor gear 127 at the gear teeth 18 and is driven while sliding. Further, when the suction rotor 117 is inclined, there is a possibility that the suction rotor shake prevention wall 30 may be rotated while being in contact with the rotor gear 127. For this reason, the drive gear 126 is preferably made of a slippery material and is preferably formed of polyacetal (POM) or the like.
