Description

  The present invention relates to a dehumidifying device used for drying clothes, for example.

  The configuration of this type of conventional dehumidifier is as follows.

That is, a main body case having an intake port and an exhaust port, a dehumidifying body provided in the main body case, and a heat exchanging means are provided. The dehumidifying rotor includes an annular outer peripheral frame member, a disc-shaped rotor provided in the outer peripheral frame member, a cylindrical bearing portion provided in the central portion, and the bearing portion. And a pressing member provided so as to press the rotor on the outer peripheral frame member (for example, a prior document similar to this is described in Patent Document 1 below).
Japanese Patent Laid-Open No. 2002-326012

  The problem in the conventional example is that the dehumidifying ability is further increased.

  That is, the dehumidifying device adsorbs moisture at the moisture absorbing portion of the dehumidifying rotor within the main body case, and then turns the dehumidifying rotor to make the moisture absorbing portion a moisture releasing portion. Thus, the dehumidifying operation by the adsorption is effectively performed again at the moisture absorbing portion of the dehumidifying rotor.

  Now, the dehumidifying rotor effective as the dehumidifying operation as described above is composed of four parts including a rotor, an outer peripheral frame member, a bearing portion, and a pressing member.

  Specifically, an outer peripheral frame member is provided on the outer periphery of the rotor, and a bearing portion is provided at the center. The rotor is sandwiched and held by the outer peripheral frame member, the bearing portion, and the pressing member, and the outer frame is fixed by the fixing portion of the pressing member. It is being fixed with the member and the bearing part.

  As described above, the pressing member has a holding portion and a fixing portion for holding the rotor. However, since the dehumidification rotor rotates, the pressing member further guides the rotation of the dehumidification rotor to be smooth. It has a guide. That is, the area of the pressing member has the area of the holding part that holds the rotor, the area of the fixing part, and the area of the guide part for smooth rotation of the dehumidifying rotor. That is, since the area covering the ventilation hole of the ventilation structure of the dehumidifying rotor is increased, the ventilation area is reduced as a result, and the dehumidifying ability cannot be further increased.

  Therefore, the object of the present invention is to further increase the dehumidifying ability.

  In order to achieve this object, the present invention comprises a main body case having an intake port and an exhaust port, a dehumidifying body provided in the main body case, and a heat exchanging means. A dehumidifying rotor comprising a moisture absorbing portion is provided in a rotor case so as to be rotatable. The dehumidifying rotor is provided in an annular outer peripheral frame member, a disc-shaped rotor provided in the outer peripheral frame member, and a central portion thereof. A cylindrical bearing portion and a pressing member provided to hold the rotor on the outer periphery frame member and the bearing portion, and when the dehumidifying rotor rotates, in the vicinity of the fixing portion of the pressing member to the outer frame member And at least one of the vicinity of the fixed portion to the bearing portion is brought into contact with a partition portion that partitions the moisture release portion and the moisture absorption portion of the rotor case earlier than the pressing member between the two fixed portions, By It is intended to achieve the fiscal objectives of.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, a dehumidifying body provided in the main body case, and a heat exchanging means, and the dehumidifying body includes a moisture releasing portion and a moisture absorbing portion. A dehumidifying rotor is rotatably provided in the rotor case, and the dehumidifying rotor includes an annular outer peripheral frame member, a disc-shaped rotor provided in the outer peripheral frame member, and a cylindrical bearing provided in the central portion. And a bearing member provided so as to press the rotor on the outer peripheral frame member, and when the dehumidifying rotor rotates, in the vicinity of the fixing portion of the pressing member to the outer frame member, and the bearing At least one in the vicinity of the fixed part to the part is brought into contact with the partition part that partitions the moisture releasing part and the moisture absorbing part of the rotor case earlier than the pressing member between the two fixed parts. More ability One in which it is possible to increase.

  In other words, the pressing member has an outer peripheral frame member and a fixing portion fixed to the bearing portion. The rotor is sandwiched between the outer peripheral frame member and the bearing portion and the pressing member and held by the holding portion, and the outer frame is fixed by the fixing portion of the pressing member. It is fixed to the member and the bearing part. Thus, the pressing member has a holding part and a fixing part.

  Then, the dehumidification rotor first comes into contact with the partition portion separating the moisture release vent hole and the moisture absorption vent hole provided on the leeward side of the moisture release portion of the rotor case, and then the vicinity of the fixing portion of the pressing member is in contact with the partition portion. The holding part rotates while contacting.

  As a result, the vicinity of the fixing portion of the pressing member is fixed to the outer peripheral frame member and the bearing portion, so that it is in close contact with the rotor, and is not caught by the partition portion that partitions the moisture release vent hole and the moisture absorption vent hole. The dehumidifying rotor rotates smoothly.

  That is, since the pressing member smoothly rotates the dehumidification rotor between the portion that holds the rotor and the fixing portion, a separate guiding portion for smooth rotation of the dehumidification rotor becomes unnecessary. Therefore, the area of the pressing member is only an area for holding the rotor and the fixing portion, and the area of the pressing member can be reduced. That is, the area covering the ventilation hole of the ventilation structure of the dehumidification rotor is reduced, the ventilation area is increased, and as a result, the dehumidification capability can be further increased.

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

(Embodiment 1)
As shown in FIGS. 1-2, the main body case 3 which has the inlet 1 and the exhaust port 2, and the heat exchanger 5 which is a dehumidifier 4 and a heat exchange means are provided in this main body case 3. As shown in FIG. The dehumidifying body 4 is provided in a rotor case 9 so that a dehumidifying rotor 8 composed of a moisture releasing portion 6 and a moisture absorbing portion 7 is rotatable, and the rotor case 9 is provided with a moisture releasing ventilation hole 10 and a moisture absorbing portion. The part 7 is provided with a moisture absorption ventilation hole 11.

  The main body case 3 is provided with air blowing means and circulation air blowing means. The blower 12 that is a blowing means blows air from the intake port 1 to the exhaust port 2 through the hygroscopic portion 7 and the heat exchanger 5 through another path, and the blower 13 that is a circulating blower means exchanges heat with the moisture release unit 6. The unit 5 circulates and blows air. A heating means 15 is provided in the circulation air passage 14 through which air is circulated from the heat exchanger 5 to the moisture release unit 6.

  Next, the dehumidifying operation will be described. The indoor air is sent from the air inlet 1 to the moisture absorption unit 7 by the blower 12, and moisture is adsorbed by the moisture absorption unit 7 to be dehumidified. The dehumidified air is blown from the exhaust port 2 into the room. Further, when the dehumidifying rotor 8 rotates, the moisture absorbing portion 7 becomes the moisture releasing portion 6, and then the air heated by the heating means 15 by the blower 13 is blown to the moisture releasing portion 6 and heated. Moisture adsorbed by the dehumidifying rotor 8 is released into the air and becomes high-temperature and high-humidity air. The high-temperature and high-humidity air is blown to the heat exchanger 5. At the same time, indoor air is blown from the air inlet 1 to the heat exchanger 5 by the blower 12 through another path. Thereby, in the heat exchanger 5, the high-temperature and high-humidity air is cooled by the indoor air and is dehumidified by condensation in the heat exchanger 5.

  The feature of the present embodiment resides in the structure of the dehumidifying rotor 8. As shown in FIG. 3, the dehumidifying rotor 8 includes a disc-shaped rotor 17, an outer peripheral frame member 16 having an annular shape on the outer periphery of the rotor 17 and a flange on one end face inside, and a cylindrical member at the center. And a plurality of pressing members 19 between the outer peripheral frame member 16 and the bearing portion.

  The holding member 19 includes a bearing 20 which is a fixed portion of the outer peripheral frame fixing portion 21 which is a fixed portion to the outer peripheral frame member 16 at one end of the holding portion 20 which is a linear sheet metal, and a bearing portion 18 which is fixed to the other end. And a fixing portion 22.

  That is, the rotor 17 is sandwiched between the flange 23 on the inner end surface of the outer peripheral frame member 16 and the flange 24 on the outer end surface of the bearing portion 18 and the holding portion 20 of the pressing member 19, and is fixed by the outer peripheral frame fixing portion 21 and the bearing fixing portion 22. Has been.

  Therefore, the center line 25 in the longitudinal direction of the holding portion 20 which is a linear sheet metal of the pressing member 19 has a predetermined distance from the center 26 of the dehumidifying rotor.

  Specifically, the pressing member 19 has a predetermined distance in the radial direction from the bearing fixing portion 22 fixed to the bearing portion 18 at the center of the rotor 17, and is held in a tangential direction opposite to the rotation direction. The portion 20 extends and is fixed to the outer peripheral frame member 16 by an outer peripheral frame fixing portion 21 bent into an L shape at the tip.

  As a result, when the dehumidifying rotor 8 is rotated, the bearing fixed as the central portion of the dehumidifying rotor 8 is fixed to the two partition portions 27 extending in the radial direction from the center provided on the leeward side of the moisture releasing portion 6 of the rotor case 9. The vicinity of the portion 22 first contacts and gradually contacts the vicinity of the outer peripheral frame fixing portion 21 of the outer peripheral portion from the central portion while contacting the holding portion 20.

  That is, when the dehumidifying rotor 8 rotates, the bearings of the pressing member 19 are provided on the two partition portions 27 that partition the moisture release vent hole 10 and the moisture absorption vent hole 11 provided on the leeward side of the moisture release portion 6 of the rotor case 9. The vicinity of the fixing portion 22 is first contacted. Thereby, even when the holding part 20 floats from the rotor 17, since the vicinity of the bearing fixing part 22 in the pressing member 19 is fixed to the bearing part 18, the holding part 20 is in close contact with the rotor 17, and the two partitions The dehumidifying rotor 8 rotates smoothly without being caught by the portion 27.

  Therefore, since the holding member 20, the bearing fixing portion 22, and the outer peripheral frame fixing portion 21 smoothly rotate the dehumidification rotor, the holding member 19 does not need a guiding portion for smooth rotation of the dehumidification rotor. The area of the pressing member 19 can be reduced.

(Embodiment 2)
FIG. 4 is a perspective view of a dehumidification rotor according to Embodiment 2 of the present invention. As shown in FIG. 4, the holding member 19 a includes an outer peripheral frame fixing portion 21 that is a fixing portion to the outer peripheral frame member 16 at both ends of a holding portion 20 a that is a plate material, and a bearing fixing portion that is a fixing portion to the bearing portion 18. 22 and the holding portion 20a has a concave curved shape. That is, the pressing member 19a is fixed to the dehumidifying rotor 8 so as to rotate with both ends curved in a concave shape leading.

  As a result, the dehumidifying rotor 8 has two partition portions 27 extending in the radial direction from the center provided on the leeward side of the moisture releasing portion of the rotor case 9, the vicinity of the bearing portion 18 that is the central portion, and the outer peripheral portion. The vicinity of the outer peripheral frame fixing portion 21 is first contacted, and gradually rotates from the central portion and the outer peripheral portion to contact the intermediate portion between the central portion and the outer peripheral portion while being in contact with the holding portion 20a.

  Thereby, even when the holding portion 20a floats from the rotor 17, the vicinity of the bearing fixing portion 22 in the pressing member 19a is fixed to the bearing portion 18, and the vicinity of the outer peripheral frame fixing portion 21 is fixed to the outer peripheral frame fixing portion 21. Therefore, the dehumidification rotor 8 is in close contact with the rotor 17 and smoothly rotates without being caught by the two partition portions 27.

  That is, the holding member 20 smoothly rotates the dehumidification rotor by the holding portion 20, the bearing fixing portion 22, and the outer peripheral frame fixing portion 21, so that a guiding portion for smooth rotation of the dehumidification rotor is unnecessary. The area of the pressing member 19 can be reduced.

  In the present embodiment, the pressing member 19a has a concave curved shape with respect to the rotation direction. This is because, even when the holding portion 20a floats from the rotor 17 due to heat or the like, since the holding portion 20a is curved in a concave shape, the concave surface side is shorter than the convex surface side, and the concave surface side floats less than the convex surface side. Therefore, it comes into contact with the partition portion 27 from the concave side where the float is small, and the dehumidification rotor 8 can be rotated more smoothly.

(Embodiment 3)
A dehumidifier according to Embodiment 3 of the present invention will be described with reference to the drawings. As shown in FIGS. 5 to 6, a main body case 32 having an intake port 30 and an exhaust port 31 and a heat pump 33 provided in the main body case 32 are provided. The heat pump 33 is formed by a compressor 34, a radiator 35, an expansion means 36, and a heat absorber 37 that are sequentially provided downstream of the compressor 34, and radiates air sucked into the main body case 32 from the intake port 30. A blower means 38 for blowing air to the exhaust port 31 through the heat exchanger 35 and the heat absorber 37 in this order is provided, and a dehumidifier 41 is provided between the heat radiator 35 and the heat absorber 37. In the dehumidifying body 41, a dehumidifying rotor 42 including a moisture releasing portion 39 and a moisture absorbing portion 40 is rotatably provided in a rotor case 49.

  Next, the dehumidifying operation will be described. The indoor air is blown from the air inlet 30 to the heat radiator 35 by the blower 38 and heated there to be in a state where the relative humidity is low, and then sent to the moisture release portion 39 of the dehumidifying rotor 42. Therefore, the moisture is released and the relative humidity is high, and the moisture is sent to the heat absorber 37 and dewed by condensation.

  The present embodiment is characterized by the structure of the dehumidifying rotor 42. As shown in FIG. 7, the pressing member 43 includes a bearing fixing portion 45 that is a fixing portion with the bearing portion 44 at the center portion, and an outer peripheral frame fixing portion 47 that is a fixing portion with the outer peripheral frame member 46 at both ends. A holding portion 48 that is a linear plate member is provided between the bearing fixing portion 45 and the outer peripheral frame fixing portions 47 at both ends. The center line 51 in the longitudinal direction of the holding portion 48 has a shape having a predetermined distance from the center 52 of the dehumidifying rotor.

  Specifically, the pressing member 43 has a predetermined distance in the radial direction from the bearing fixing portion 45 fixed to the bearing portion 44 at the center of the rotor 57, and is held in the tangential direction opposite to the rotation direction. The part 48 extends in two directions from the center 52 of the dehumidifying rotor to the point object, and is fixed to the outer peripheral frame member 46 by an outer peripheral frame fixing part 47 bent to an L shape at the tip.

  Thus, when the dehumidifying rotor 42 rotates, the two partition portions 50 extending in the radial direction from the center provided on the leeward side of the moisture releasing portion of the rotor case 49 are in the vicinity of the bearing fixing portion 45 that is the central portion. The first contact is made, and the contact with the holding portion 48 is gradually made from the central portion to the vicinity of the outer peripheral frame fixing portion 47 that is the outer peripheral portion.

  That is, when the dehumidifying rotor 42 rotates, the bearings of the pressing member 43 are fixed to the two partition portions 50 that partition the moisture release ventilation hole 55 and the moisture absorption ventilation hole 56 provided on the leeward side of the moisture release portion of the rotor case 49. The vicinity of the part 45 is contacted first. Thereby, even when the holding part 48 floats from the rotor 57, the vicinity of the bearing fixing part 45 in the pressing member 43 is fixed to the bearing part 44, so that it is in close contact with the rotor 57 and the two partitions The dehumidifying rotor 42 rotates smoothly without being caught by the part 50.

  That is, since the holding member 20, the bearing fixing portion 22, and the outer peripheral frame fixing portion 21 smoothly rotate the dehumidification rotor, the holding member 19 does not require a guiding portion for smooth rotation of the dehumidification rotor. The area of the pressing member 19 can be reduced.

  Further, in the present embodiment, the pressing member 43 includes a bearing fixing portion 45 with the bearing portion 44 at the center portion, and an outer peripheral frame fixing portion 47 with the outer peripheral frame member 46 at both ends, and the outer periphery at both ends from the bearing fixing portion 45. A holding portion 48 that is a linear plate material is provided between the frame fixing portion 47 and the frame fixing portion 47. This is because the pressing member 43 is one, and the bearing portion 44 and one place, and the outer peripheral frame member 46 and two places can be fixed in total, so even if a plurality of pressing members 43 are not used, This is because the rotor 57 can be reliably sandwiched and fixed by the bearing portion 44, the outer peripheral frame member 46, and the pressing member 43, so that the dehumidifying rotor 42 can be easily assembled.

(Embodiment 4)
FIG. 8 is a perspective view of a dehumidification rotor according to Embodiment 4 of the present invention. As shown in FIG. 8, the pressing member 43 a includes a bearing fixing portion 45 that is a fixing portion with the bearing portion 44 at the center portion, and an outer peripheral frame fixing portion 47 that is a fixing portion with the outer peripheral frame member 46 at both ends. A holding portion 48a, which is a plate material, is provided between the bearing fixing portion 45 and the outer peripheral frame fixing portions 47 at both ends, and each of the holding portions 48a has a concave curved shape. That is, the pressing member 43a is fixed to the dehumidifying rotor 8 so as to rotate with both ends curved in a concave shape leading.

  Here, the pressing member 43a and the outer peripheral frame member 46 are fixed by the outer peripheral frame fixing portion 47 with screws 53 from the outer peripheral outer side toward the central direction. Further, the tip end portion of the screw 53 enters the rotor 42.

  The pressing member 43a and the bearing portion 44 are fixed by a screw 54, and the material of the screw 54 and the pressing member 43a is stainless steel.

  The material of the pressing member 43a may be a stainless spring material.

  As a result, the dehumidifying rotor 42 is connected to the two partition portions 50 extending in the radial direction from the center provided on the leeward side of the moisture releasing portion of the rotor case 49 in the vicinity of the bearing fixing portion 45 and the outer peripheral portion. A certain outer peripheral frame fixing portion 47 first contacts and gradually rotates from the central portion and the outer peripheral portion to the intermediate portion between the central portion and the outer peripheral portion.

  As a result, even when the holding portion 48a floats from the rotor 57, the vicinity of the bearing fixing portion 45 in the pressing member 43a is fixed to the bearing portion 44, and the vicinity of the outer peripheral frame fixing portion 47 is fixed to the outer peripheral frame fixing portion 47. Therefore, the dehumidification rotor 42 is in close contact with the rotor 57 and smoothly rotates without being caught by the two partition portions 50.

  That is, since the holding member 48a, the bearing fixing portion 45, and the outer peripheral frame fixing portion 47 smoothly rotate the dehumidification rotor 42, the pressing member does not require a guiding portion for smooth rotation of the dehumidification rotor. The area of the pressing member 43a can be reduced.

  Moreover, in this Embodiment, the pressing member 43a is made into the shape curved concavely with respect to the rotation direction. This is because, even when the holding portion 48a floats from the rotor 57 due to heat or the like, since the holding portion 48a is curved in a concave shape, the concave surface side becomes shorter than the convex surface side, and the float on the concave surface side becomes smaller than the convex surface side. Therefore, it comes into contact with the partition portion 50 from the concave side where the float is small, and the dehumidification rotor 42 can be rotated more smoothly.

  Further, in the present embodiment, the pressing member 43a includes a bearing fixing portion 45 with the bearing portion 44 at the center portion and an outer peripheral frame fixing portion 47 with the outer peripheral frame member 46 at both ends. A holding portion 48 a that is a curved plate material is provided between the outer peripheral frame fixing portion 47 and the outer peripheral frame fixing portion 47. The reason is that the pressing member 43a is one, and the bearing part 44 and one place, and the outer peripheral frame member 46 and two places can be fixed in total, so even without using a plurality of pressing members 43, This is because the rotor 57 can be reliably sandwiched and fixed between the bearing portion 44, the outer peripheral frame member 46, and the pressing member 43a, and therefore the assembly work of the outer peripheral frame member 46 can be facilitated.

  Further, in the present embodiment, the pressing member 43a is fixed by a screw 53 from the outer periphery of the outer peripheral frame member 46 toward the center, and the tip portion of the screw 53 enters the rotor. This is because not only the pressing member 43a and the outer peripheral frame member 46 are fixed by the screw 53, but also the rotor 57 and the outer peripheral frame member 46 can be fixed so as not to be displaced when the dehumidifying rotor 42 rotates.

  In the present embodiment, the pressing member 43a is fixed to the bearing portion 44 with a screw 54, and the material of the screw 54 and the pressing member 43a is stainless steel. This is because the generation of rust can be suppressed by moisture released from the rotor 57.

  In addition, in this embodiment, the material of the pressing member 43a may be a stainless spring material. By using SUS301, which is an example of a stainless steel spring material, even if the holding member 43a is bent carelessly during assembly work, the spring material is not easily bent and causes a gap with the rotor 57. It is because it can suppress becoming.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, a dehumidifying body provided in the main body case, and a heat exchanging means, and the dehumidifying body includes a moisture releasing portion and a moisture absorbing portion. A dehumidifying rotor is rotatably provided in the rotor case, and the dehumidifying rotor includes an annular outer peripheral frame member, a disc-shaped rotor provided in the outer peripheral frame member, and a cylindrical bearing provided in the central portion. And a bearing member provided so as to press the rotor on the outer peripheral frame member, and when the dehumidifying rotor rotates, in the vicinity of the fixing portion of the pressing member to the outer frame member, and the bearing At least one of the vicinity of the fixing part to the part is brought into contact with the partition part that partitions the moisture releasing part and the moisture absorbing part of the rotor case earlier than the pressing member between the two fixing parts, and has a dehumidifying ability The higher It is those that can Rukoto.

  In other words, the pressing member has an outer peripheral frame member and a fixing portion fixed to the bearing portion. The rotor is sandwiched between the outer peripheral frame member and the bearing portion and the pressing member and held by the holding portion, and the outer frame is fixed by the fixing portion of the pressing member. It is fixed to the member and the bearing part. Thus, the pressing member has a holding part and a fixing part.

  In the dehumidifying rotor, the vicinity of the fixing portion of the pressing member first comes into contact with the two partition portions that partition the moisture release vent hole and the moisture absorption vent hole provided on the leeward side of the moisture release portion of the rotor case. Then, the holding part rotates while contacting.

  As a result, the vicinity of the fixing portion of the pressing member is fixed to the outer peripheral frame member and the bearing portion, so that it is in close contact with the rotor, and is not caught by the partition portion that partitions the moisture release vent hole and the moisture absorption vent hole. The dehumidifying rotor rotates smoothly.

  That is, since the pressing member smoothly rotates the dehumidification rotor between the portion that holds the rotor and the fixing portion, a separate guiding portion for smooth rotation of the dehumidification rotor becomes unnecessary. Therefore, the area of the pressing member is only an area for holding the rotor and the fixing portion, and the area of the pressing member can be reduced. That is, the area covering the ventilation hole of the ventilation structure of the dehumidification rotor is reduced, and the ventilation area is increased. As a result, the dehumidification effect is enhanced while maintaining smooth rotation of the dehumidification rotor.

  Therefore, it is expected to be utilized as a dehumidifying device for home use or office use.
