  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a simple exploded view showing a schematic configuration of a dehumidifying apparatus according to an embodiment of the present invention.

  FIG. 2 is a schematic plan sectional view showing an embodiment of the present invention. As shown in FIG. 1 and FIG. 2, the dehumidifying device of the present embodiment is provided with a suction port 2 on the front surface of the main body case 1, and has an air outlet 3 and an operation unit 4 on the upper portion of the main body case 1. The user can operate this device and confirm the operation mode by operating the operation unit 4. The material of the main body case 1 is a resin, and an example is an ABS resin. A receiving tray 5 is provided below the main body case 1 so as to be able to appear and retract, and stores dehumidified water generated in the main body case 1.

  In the main body case 1, a dehumidifying rotor 8 having a moisture absorbing part 6 and a moisture releasing part 7, a first blowing means 9, and a circulation path 10 are provided.

  The dehumidifying rotor 8 is rotatably arranged on the partition plate 11, and its rotational drive is performed by the driving means 12.

  The first air blowing means 9 is provided in the rear of the main body case 1, and the room air sucked from the suction port 2 of the main body case 1 as shown in the first air passage 13 of FIG. After passing through the hygroscopic part 6, the air is exhausted from the air outlet 3 to the outside of the main body case 1. A dehumidifying rotor 8 is provided in front of the first blowing means 9.

  The dehumidifying rotor 8 is constituted by a cylindrical honeycomb rotor that can ventilate the adsorbent in the axial direction, and this adsorbent can hold a large amount of water if the relative humidity of the exposed air is high. Since the amount of water that can be held decreases as the humidity decreases, repeated contact with multiple air with different relative humidity will result in a difference in the amount of water that can be held by the adsorbent at each relative humidity. Accordingly, moisture is absorbed and desorbed.

  The circulation path 10 includes a moisture release unit 7 of the dehumidification rotor 8, a heating unit 15 that is a heating unit provided on the windward side of the moisture release unit 7, and a regeneration chamber unit 16 provided on the leeward side of the moisture release unit 7. And a heat exchanger 14 provided on the leeward side of the regeneration chamber section 16 and a second air blowing means 18 provided on the leeward side of the heat exchanger 14 for circulating the air in the circulation path 10. . The circulation path 10 is independent as a ventilation path in the main body case 1.

  FIG. 3 is an exploded perspective view of the regeneration chamber section 16 and the partition plate 11. As shown in FIG. 3, the regeneration chamber portion 16 is formed of a chamber 19 and a chamber cover 20 in the shape of a box having a partially hollow structure. The regeneration chamber portion 16 constitutes a part of the circulation path 10 and includes a plurality of openings. One of these openings is located downstream of the moisture release portion 7 of the dehumidification rotor 8 and opens in a fan shape so as to follow the shape of the moisture release portion 7. In addition, the periphery of the fan-shaped opening is configured by a smooth plane, and has a shape that improves the airtightness with the dehumidifying rotor 8. Another opening of the regeneration chamber section 16 is upstream of the heat exchanger 14 and has a square shape similar to the air path downstream of the opening configured by the partition plate 11 and the like, and has a fan-shaped opening. The direction of the part and the opening are different.

  Specifically, if the fan-shaped opening is the front, the square-shaped opening corresponds to the side surface. The regeneration chamber portion 16 is provided with a plurality of holes to which screws can be attached, and is used to fix the regeneration chamber portion 16 and the partition plate 11, and the regeneration chamber portion 16 and the heat generating means 15 outer shell. There is an axis serving as the center of the dehumidifying rotor 8 in the fan-shaped central portion of the plane around the fan-shaped opening, and the dehumidifying rotor 8 is held without being fixed.

  One of the roles of the regeneration chamber section 16 is to change the wind direction of the high-temperature superhumid air that has passed through the heat generating means 15 and the dehumidifying section 7 of the dehumidifying rotor 8, and while cooling the high-temperature air, To send it to. Therefore, the regeneration chamber portion 16 is easily kept at a high temperature, and the regeneration chamber portion 16 is higher in heat resistance than the main body case 1. In particular, in a portion where high-temperature air flows, the sheet metal 30 is used so that the high-temperature air is not directly blown onto the resin.

  The sheet metal 30 is smaller than the opening on the upstream side of the regeneration chamber section 16 and has a fan shape so as to follow the arc shape of the opening, and is parallel to the downstream surface of the moisture releasing section 7 of the dehumidifying rotor 8. It is arranged so as not to come into contact with the surface and at a distance from the chamber cover 20 on the downstream side of the regeneration chamber section 16. Further, a part of the sheet metal 30 also constitutes a part of a contact surface between the regeneration chamber portion 16 and the dehumidifying rotor 8, thereby improving the durability of the regeneration chamber portion 16 and improving the airtightness with the dehumidifying rotor 8. It is also effective for holding.

  Furthermore, as shown by an arrow A in FIG. 2, the indoor air sucked into the main body case 1 from the suction port 2 by the first blower 9 passes through the heat exchanger 14 of the circulation path 10 in the main body case 1. Thereafter, an air passage for exhausting air from the air outlet 3 to the outside of the main body case 1 is formed via the first air blowing means 9.

  However, the indoor air indicated by the arrow A is only heat exchanged with the air in the circulation path 10 passing through the heat exchanger 14 through the heat conduction surface constituting the heat exchanger 14. It is not mixed in 14 parts.

  A first air blowing means 9 is provided on the rear side in the main body case 1, and a dehumidifying rotor 8 is provided on the front side in the main body case 1. A heating means 15 is provided between the first blowing means 9 and the dehumidifying rotor 8. A regeneration chamber portion 16 is provided between the dehumidification rotor 8 and the front surface of the main body case 1.

  Here, the operation of the circulation path 10 will be described. The air in the circulation path 10 heated by the heat generating means 15 releases moisture in the moisture release section 7, and this high-temperature and overhumid air is leeward. It flows into the regeneration chamber section 16 provided in the above. The high temperature air is first blown onto the sheet metal 30 in the regeneration chamber section 16, and then proceeds to the cavity in the regeneration chamber section 16 while changing the wind direction, and further on the leeward side through the air path composed of the partition plate 11 and the like. It is sent to the heat exchanger 14. As described above, since the indoor air is blown to the heat exchanger 14 by the first blowing means 9 as shown by the arrow A in FIG. 2, the high-temperature and excessively humid air is cooled, thereby dew condensation. This is stored in the tray 5.

  The moisture absorbing section 6 of the dehumidifying rotor 8 adsorbs moisture every time indoor air passes through the first air passage 13, and this becomes the moisture releasing section 7 described above by the rotation of the dehumidifying rotor 8, and circulates. Moisture is released into the path 10 and the indoor air is dehumidified by such circulation.

  A feature of this embodiment is that a heat shield wall 21 is provided between the regeneration chamber portion 16 and the main body case 1 as shown in FIG. 3, and a gap is provided between the heat shield wall 21 and the regeneration chamber portion 16. It is. That is, the heat shielding means is provided between the main body case 1 and the outer surface of the regeneration chamber portion 16 on the front surface side of the main body case 1. Thereby, heat leaking from the outer wall of the regeneration chamber portion 16 is insulated by the air barrier partitioned by the heat shield wall 21 and the heat shield wall 21, and can be reduced from reaching the main body case 1. As a result, the durability of the resin forming the main body case 1 can be improved.

  Specifically, FIG. 4 is an internal plan view of one embodiment of the present invention. As shown in FIGS. 3 and 4, a heat shield wall 21 is provided on the outer surface of the regeneration chamber portion 16 on the front side of the main body case 1, and the heat shield wall 21 covers a part of the regeneration chamber portion 16. A space is provided between the outer shell of the portion 16 and the heat shield wall 21.

  As shown in FIG. 3, the heat shield wall 21 is formed on a part of the side surface and the back surface of the regeneration chamber portion 16. This is because the high-temperature air that has passed through the dehumidification rotor flows to the outer peripheral side with respect to the rotation direction of the dehumidification rotor 8 by the sheet metal 30 provided in the regeneration chamber unit 16. It is preferable to provide a heat shield wall 21 at a high temperature portion and provide an air layer between the heat shield wall 21 and the regeneration chamber portion 16. Thereby, heat leaking from the outer wall of the regeneration chamber portion 16 is insulated by the air barrier partitioned by the heat shield wall 21 and the heat shield wall 21, and can be reduced from reaching the main body case 1. As a result, the durability of the resin forming the main body case 1 can be improved.

  The heat shield wall 21 is lower in heat resistance than the regeneration chamber portion 16, but higher in heat resistance than the main body case 1.

  Further, the heat shield wall 21 is constituted by a part of the partition plate 11. The original purpose of the partition plate 11 is to separate the air to be dehumidified before passing through the moisture absorbing portion 6 of the dehumidifying rotor 8 and the dry air after passing through the moisture absorbing portion 6 of the dehumidifying rotor 8. Furthermore, it is one of the elements constituting the inside of the main body case 1 such as supporting the dehumidifying rotor 8 and attaching each component. The partition plate 11 constitutes the heat shield wall 21.

  As shown in FIG. 3, the partition plate 11 has a cylindrical cavity for holding the dehumidification rotor 8 inside the rectangular plate shape, and a hollow disk-like plane inside the cylinder, and holds the dehumidification rotor 8 on the plane. The dehumidifying rotor 8 is housed in the cylinder, and the hollow portion becomes the first air passage 13. Driving means 12 for rotating the dehumidifying rotor 8 is attached to the lower part of the partition plate 11 on a circle forming a cylinder. In addition, a cylinder and a hollow disk are not provided on the upper side of the partition plate 11 and not adjacent to the heat exchanger 14, and a flat plate is provided on the upstream side of the first air passage 13. The flat plate is attached with the top and side surfaces of the partition plate 11. The flat plate supports the structure of the partition plate and holds the reproduction chamber portion 16 in a space surrounded by the flat plate, the top surface, and the side surface. Furthermore, the lower part of the partition plate 11 has a U-shape, and forms a part of the air path between the heat exchanger 14 and the second air blowing means 18 in the circulation path 10.

  The heat shield wall 21 is provided on the upstream side of the first air passage 13 of the regeneration chamber section 16, that is, between the regeneration chamber section 16 and the main body case 1. To cover. That is, it is a region that is not covered with the sheet metal 30 provided in the regeneration chamber section 16 and that is on the outer side of the outer periphery of the dehumidifying rotor 8 and on the side surface of the regeneration chamber section 16. As shown in FIG. 3, by configuring the heat shield wall 21 with a part of the partition plate 11, an effective regeneration chamber portion 16 heat shield means can be provided without increasing the number of parts. In addition, since the gap is not generated between the partition plate 11 and the heat shield wall 21 by molding with an integral part, the high-temperature air generated in the outer wall of the regeneration chamber does not flow out of the heat shield wall 21. Thus, the effect of the heat shield wall 21 can be further enhanced. As a result, the durability of the resin forming the main body case 1 can be improved.

  A part of the suction port 2 is opposed to the heat shield wall 21. The role of the suction port 2 is opened in order to supply air to the moisture absorption part 6 and the heat exchanger 14 of the dehumidification rotor 8. By expanding the suction port 2 to the outer wall of the heat shield wall 21, the heat shield wall 21 itself can be cooled. Moreover, the partition plate 11 is provided with a part of the space with the main body case 1 so that air also flows through the outer wall of the heat shield wall (FIG. 3, second partition plate surface) on the side surface of the regeneration chamber 16. Can do. In this way, by taking outside air into the outer wall of the heat shield wall 21, the temperature rise of the heat shield wall 21 and the main body case 1 can be reduced. As a result, the durability of the resin forming the main body case 1 can be improved.

  As described above, the regeneration chamber section 16 includes the chamber 19 on the dehumidifying rotor 8 side and the chamber cover 20 on the first partition plate surface side of the heat shield wall 21 as shown in FIG. This is a complicated structure in which the regeneration chamber portion is hollow, and is mainly for reasons of molding.

  A part of the heat shield wall 21 is in contact with the chamber cover 20 in the regeneration chamber section 16. As shown in FIG. 3, the chamber cover 20 is configured by a plurality of planes of a first cover surface 22 and a second cover surface 23 that are adjacent to each other in the left-right direction in the main body case 1. The heat shield wall 21 facing the chamber cover 20 is constituted by a first partition plate surface 24.

  The first cover surface 22 of the chamber cover 20 is parallel to the first partition plate surface 24 of the heat shield wall 21 and extends from the end of the first cover surface 22 of the chamber cover 20. The cover surface 23 is inclined toward the dehumidifying rotor. That is, when the chamber cover 20 is incorporated in the partition plate 11, the first cover surface 22 contacts the first partition plate surface 24, but the second cover surface 23 contacts the first partition plate surface 24. Instead, an air layer is formed between the chamber cover 20 and the heat shield wall 21.

  In the air flow direction in the circulation path 10, the first cover surface 22 is on the leeward side of the regeneration chamber portion 16, and the second cover surface 23 is on the leeward side of the regeneration chamber portion 16.

  In other words, the second cover surface 23 that is on the leeward side of the regeneration chamber portion 16 has a higher temperature than the first cover surface 22 that is on the leeward side of the regeneration chamber portion 16. That is, if an air layer is formed between the chamber cover 20 and the heat shield wall 21 without being in contact with the first partition plate surface 24, the heat leaking from the outer wall of the regeneration chamber portion 16 is not in contact with the heat shield wall 21. It is insulated by the air layer divided by the wall 21, and it can reduce reaching to the main body case 1. As a result, the durability of the resin forming the main body case 1 can be improved. Note that the effect of the air layer can be maximized by providing the air layer on the outer peripheral side of the dehumidifying rotor 8 that is carried by the sheet metal 30 provided in the regeneration chamber section 16. That is, by providing the area on the outer peripheral side of the dehumidifying rotor 8 on the second cover surface 23 that is larger than the first cover surface 22, the effect can be maximized.

  The chamber 19 and the chamber cover 20 that form the regeneration chamber portion 16 have ribs formed on the chamber cover 20 side and are fitted like a lid, but form an air layer that is a heat insulating means for the regeneration chamber portion 16. Then, it becomes difficult to hold down the chamber cover 20, and depending on the risk of assembly failure or long-term use, the chamber 19 and the chamber cover 20 are less likely to be fitted, and the high-temperature air flowing inside the regeneration chamber section 16 is generated by the regeneration chamber. There is a possibility of flowing out of the portion 16.

  That is, the first cover surface 22 is in contact with the first partition plate surface 24, so that the chamber cover 20 can be pressed by the heat shield wall 21, and the lid-shaped chamber cover 20 is prevented from opening. Is possible. It is possible to prevent high temperature air from flowing out of the regeneration chamber section 16 and to partially form an air layer, thereby reducing the heat of the outer contour of the regeneration chamber section 16 from reaching the outer shell. As a result, the durability of the resin forming the main body case 1 can be improved.

  In addition, a plurality of ribs are provided between the chamber cover 20 and the heat shield wall 21 in the regeneration chamber portion 16. FIG. 5 is an enlarged perspective view of the partition plate according to the embodiment of the present invention. As shown in FIG. 5, part of the first partition plate surface 24 of the heat shield wall 21 is in contact with the second cover surface 23 at a lower part of the portion of the chamber cover 20 that does not contact the first cover surface 22. A first rib 26 is formed on the lower end surface of the first partition plate surface 24 in the shape. Specifically, the lower end portion of the first partition plate surface 24 has an arc shape. A protrusion extending from a part of the lower end portion toward the reproduction chamber portion 16 and toward the second cover surface is a first rib 26.

  A second rib 27 having a height that does not contact the second cover surface 23 is formed on the first partition plate surface 24 so as to be adjacent to the first rib 26. The second rib 27 has a predetermined distance from the first rib 26 and is located above the first rib 26.

  As a result, high-temperature and excessively humid air in the regeneration chamber section 16 is condensed, and condensed water leaks from the gap between the chamber 19 and the chamber cover 20 to the outer wall of the regeneration chamber section 16, and the heat shield wall 21 is used as a path. Even if it is about to flow out to the outside, it can be recovered as dehumidified water through the first rib 26 and the second rib 27 without dripping from the outer shell of the regeneration chamber section 16. A communication path communicating with the tray 5 is provided below the lower ends of the first rib 26 and the second rib 27.

  The first rib 26 is partly brought into contact with the second cover surface 23 of the chamber cover 20, thereby exhibiting an effect of preventing the condensed water from leaking and can also be expected to hold down the chamber cover 20. Thereby, it is possible to prevent the lid-shaped chamber cover 20 from opening, prevent outflow of high-temperature air from the regeneration chamber section 16, and suppress an increase in temperature inside the heat shield means. As a result, the durability of the resin forming the main body case 1 can be improved. In addition, when the second rib 27 is adjacent to the first rib 26, when condensed water leaks out of the regeneration chamber portion 16, it is immediately guided to the lower part of the heat shield wall 21 by capillary action. It is.

  In addition, as shown in FIG. 5, the first partition plate surface 24 of the heat shield wall 21 also includes a plurality of third ribs 28 at equal intervals on a straight line toward the second cover surface 23 of the chamber cover 20. Form. Thereby, it becomes possible to prevent the chamber cover 20 from opening more reliably. Thereby, outflow of high temperature air from the reproduction | regeneration chamber part 16 can be prevented, and the temperature rise inside a thermal-insulation means can be suppressed. As a result, the durability of the resin forming the main body case 1 can be improved.

  In addition, as shown in FIG. 5, a plurality of fourth ribs 29 are formed on the second partition plate surface 25 of the heat shield wall 21 in a straight line toward the insertion direction of the regeneration chamber portion 16. The fourth rib 29 supports the regeneration chamber portion 16 in a direction perpendicular to the second partition plate surface 25. As a result, the air passage formed by the partition plate 11 and the like and provided between the regeneration chamber portion 16 and the heat exchanger 14 and the regeneration chamber portion 16 upstream of the air passage in the circulation path 10 are more joined. It becomes reliable, and it becomes possible to reduce the leakage of the dew condensation water generated in the regeneration chamber section 16 and the air passage and the high-temperature air in the circulation passage 10. As a result, the durability of the resin forming the main body case 1 can be improved.

  The dehumidifying device according to the present invention provides a heat-resistant means for reducing the temperature rise of the main body case due to heat radiation from the regeneration chamber, and is useful for an air conditioner using a dehumidifying rotor.
