The configuration was more removable.

For example, a similar prior document is described in Patent Document 1 below.
JP 2008-200596 A

  The problem in the above conventional example is that the weight of the water tank is heavy.

  In other words, in the conventional product, the handle is connected directly to the water tank so that the water tank can be pulled out of the main body case and held by the handle. Cracks due to impact were likely to occur at the joints of the aquarium.

  Therefore, in the past, the thickness of the connecting part of the aquarium was increased or the strength was increased by attaching ribs. However, if there is a weak part of the aquarium, that is, a thin part, stress concentration occurs, resulting in cracks due to impact. Therefore, the thickness of the water tank was uniformly increased.

  Accordingly, the object of the present invention is to reduce the weight of the water tank by reducing the thickness.

  In order to achieve this object, the present invention comprises a main body case having an intake port and an exhaust port, a dehumidifying means provided in the main body case, and a drain means provided below the dehumidifying means. The means is a box-shaped water tank with an open top, a U-shaped fixed frame that covers the bottom surface and both side surfaces of the water tank at the center of the water tank, and a handle portion that is rotatably provided near both ends of the fixed frame. And a lid portion detachably provided in the upper opening of the water tank, the drain means is removable from the side opening of the main body case, and the fixing frame is a polyolefin resin, To achieve the initial objectives.

  As described above, the present invention includes a main body case having an air inlet and an exhaust port, a dehumidifying means provided in the main body case, and a drain means provided in a lower portion of the dehumidifying means, and the drain means has an upper portion. An open box-shaped water tank, a U-shaped fixed frame covering the bottom surface and both side surfaces of the water tank at the center of the water tank, a handle portion rotatably provided near both ends of the fixed frame, and the water tank The drain means is detachable from the opening on the side of the main body case, and the fixing frame is made of polyolefin resin, so that the thickness of the water tank is reduced. Thus, the weight can be reduced.

  That is, since the handle and the water tank are connected via the fixed frame, the impact from the handle is transmitted to the connection part between the handle and the fixed frame, and further transmitted to the connection part between the fixed frame and the water tank.

  First, since the fixed frame is a polyolefin-based resin, it is deformed when an impact is applied, and the impact is absorbed by deformation, so that the generation of cracks is suppressed.

  Next, since the fixed frame is fixed in a U shape so as to cover the bottom surface and both side surfaces of the water tank, the U shape is maintained by the water tank, and the fixing frame and the water tank Since the impact transmitted to the connecting portion is received by the bottom surface and both side surfaces of the water tank, stress concentration is unlikely to occur, and as a result, cracks due to the impact are less likely to occur.

  Based on these results, the water tank can be made thinner and lighter.

  Hereinafter, the present embodiment will be described with reference to the accompanying drawings.

As shown in FIG. 1, the dehumidifying device of this embodiment includes a main body case 3 having an intake port 1 and an exhaust port 2, and a heat pump 4 provided in the main body case 3. The heat pump 4 is formed by a compressor 5, a radiator 6, expansion means 7, and a heat absorber 8. The air sucked into the main body case 3 from the air inlet 1 by the air blowing means 9 is blown to the air outlet 2 through the radiator 6 and the heat absorber 8 in order. A dehumidifying rotor 10 is rotatably provided between the radiator 6 and the heat absorber 8 in the air path of the air blowing means 9, and the dehumidifying rotor 10 includes a moisture releasing portion 11 and a moisture absorbing portion 13. .

  The moisture releasing part 11 is provided in the air path between the radiator 6 and the heat absorber 8, and the moisture absorbing part 13 is provided in the air path between the heat absorber 8 and the exhaust port 2. A heater 12 serving as a heating means is provided between them.

  That is, the dehumidifying means is formed by the heat pump 4, the dehumidifying rotor 10, and the heater 12.

  The dehumidifying operation with the above configuration will be described. The air sucked into the main body case 3 from the air inlet 1 by the air blowing means 9 is heated by the radiator 6 and then further heated by the heater 12 to become air having high temperature and low relative humidity, and the moisture releasing portion 11 of the dehumidifying rotor 10. It is blown to. The air blown to the moisture release section 11 takes in the moisture of the moisture release section 11 and is sent to the heat absorber 8 in a high humidity state. The heat absorber 8 is condensed to dehumidify and reaches the moisture absorbing portion 13. Therefore, the moisture releasing portion 11 of the dehumidifying rotor 10 in a dry state is rotated by the driving means 14 to become the moisture absorbing portion 13. The moisture absorbing portion 13 absorbs and dehumidifies the humidity not dehumidified by the heat absorber 8. The condensed water condensed by the heat absorber is collected by the drain means 15.

  As shown in FIGS. 2 and 3, the feature of the present embodiment is the configuration of the drain means 15 that is located at the lower part of the dehumidifying means and is detachable from the opening on the side surface of the body case 3. The drain means 15 is formed of a water tank 16, a handle part 17, and a fixed frame 18, and the water tank 16 and the handle part 17 are fixed via a fixed frame 18. Moreover, the upper opening of the water tank 16 is equipped with the cover part 19 so that attachment or detachment is possible.

  First, the fixing structure of the water tank 16 and the fixing frame 18 is such that the U-shaped fixing frame 18 is fixed at the center of the box-shaped water tank 16 opened at the top so as to cover the bottom surface and both side surfaces of the water tank 16. ing.

  In other words, the water tank 16 is fitted into the groove portion 20 provided on the bottom surface and both side surfaces of the water tank 16 at the center portion, and fixed by the plurality of claw portions 21 provided in the groove portion 20. The claw portion 21 provided in the water tank 16 is provided on one side of the groove portions 20 on both sides of the water tank 16, and the claw portion 21 is positioned on the near side when the water tank 16 is mounted from the opening on the side surface of the main body case 3. The side groove 20 is provided.

  In this way, by fixing the fixing frame 18 to the groove portions 20 provided on the bottom surface and both side surfaces of the water tank 16 at the center of the water tank 16, the water tank 16 is transported when the water tank 16 holding water 17 is carried. Can be easily balanced.

  In addition, by providing the claw portion 21 on one side of the both side groove portions 20 of the water tank 16 in this way, when fixing the fixed frame 18 to the water tank 16, the fixed frame 18 is fitted to the claw portion 21 of the water tank 16 from one direction. By fixing, the fixing frame 18 can be fixed to the water tank 16, so that the fixing frame 18 can be easily fixed to the water tank 16.

  Further, in this way, the claw portion 21 provided in the water tank 16 is provided in the side groove portion 20 located on the near side when the water tank 16 is mounted from the side surface opening of the main body case 3. When holding and pulling the handle portion 17 to drain the water accumulated in the tank, a force acts in a direction to fit the fixed frame 18 into the claw portion 21 of the water tank 16, so that the fixed frame 18 is difficult to come off from the water tank 16. . When the water tank 16 is inserted into the main body case 3 after draining, the side of the water tank 16 is pushed and attached to the main body case 3 without using the handle portion 17, so that the fixing frame 18 is detached from the claw portion 21 of the water tank 16. There is no power to work.

  Next, as shown in FIG. 4, the fixing structure of the fixed frame 18 and the handle portion 17 includes a handle holding hole portion 18 a in the vicinity of both ends of the fixed frame 18, a handle portion 17 having a handle shaft portion 17 a and a handle holding portion 17 b. It is provided rotatably through the.

  Specifically, the handle portion 17 is substantially U-shaped, and includes a cylindrical handle shaft portion 17a on the outer surface near both ends, and a handle holding portion 17b at the tip of the handle shaft portion 17a. The handle holding portion 17b is formed of a disc-shaped hook portion and a substantially semi-circular retaining portion provided on a part of the outer periphery of the hook portion. Further, near the both ends of the fixed frame 18, the handle holding hole portion 18a having the same shape as the handle holding portion 17b and including a hook hole portion into which the hook portion can be inserted and a retaining hole portion into which the retaining portion can be inserted. The catch portion can be inserted into the handle holding hole 18a only at a specific angle. The retaining hole 18a of the handle holding hole 18a is located at the lower part of the hooking hole, and the handle 17 can be inserted into the handle holding hole 18a when the handle 17 is in a horizontal state. When attached to 16, the retaining hole is closed by the water tank.

  That is, after the handle holding part 17b of the handle part 17 is inserted into the handle holding hole part 18a near the both ends of the fixed frame 18 at a specific angle and then the fixed frame 18 is attached to the water tank 16, the retaining hole part becomes the water tank 16 The hole of the fixed frame 18 is only the catching hole portion. As a result, the retaining portion 17 of the handle portion 17 is not caught in the catching hole portion of the fixed frame 18 and thus cannot be detached.

  Thus, since the handle part 17 cannot be detached from the fixed frame 18 fixed to the water tank 16, the water tank 16 is detached from the handle part 17 when carrying the handle part 17 to drain the water accumulated in the water tank 16, No water spills.

  The fixed frame 18 is a polyolefin resin. Specifically, the material of the fixed frame 18 is polypropylene (PP) or polystyrene (PS).

  As described above, since the fixed frame 18 is a polyolefin-based resin, when an impact is transmitted to the fixed frame 18, the deformation is absorbed by the deformation, so that the generation of cracks is suppressed.

  Further, the peripheral thickness of the handle holding hole portion 18a of the fixed frame 18 is thicker than the thicknesses of the other fixed frames.

  As a result, the strength around the handle holding hole portion 18a of the fixed frame 18 is increased, and it is further difficult for cracks to occur due to impact.

  Moreover, as shown in FIG. 5, the part which covers the bottom face of the water tank 16 of the fixed frame 18 is provided with the some rib 22. As shown in FIG. The direction of the rib 22 is the same as the direction in which the water tank 16 is pulled out.

  Thereby, when the water tank 16 is pulled out, the contact area between the water tank 16 and the main body case 3 is reduced, so that the contact resistance is reduced and the water tank 16 can be pulled out easily.

  The material of the water tank 16 is acrylonitrile butadiene styrene (ABS), general purpose polystyrene (GPPS), or polystyrene (PS).

  In this way, by making the material of the water tank 16 acrylonitrile butadiene styrene (ABS), general purpose polystyrene (GPPS) or polystyrene (PS), the water accumulated in the water tank can be confirmed from the outside via the water tank 16. Therefore, the water accumulated in the water tank can be confirmed without pulling out the water tank 16 as the drain means 15 from the opening on the side surface of the main body case 3.

  The material of the handle portion 17 is acrylonitrile butadiene styrene (ABS).

  Accordingly, when the handle portion 17 is attached to the fixed frame 18, the handle portion 17 can be deformed and attached to the fixed frame 18, so that the handle portion 17 can be easily attached to the fixed frame 18.

  As described above, the present invention includes a main body case having an air inlet and an exhaust port, a dehumidifying means provided in the main body case, and a drain means provided in a lower portion of the dehumidifying means, and the drain means has an upper portion. An open box-shaped water tank, a U-shaped fixed frame covering the bottom surface and both side surfaces of the water tank at the center of the water tank, a handle portion rotatably provided near both ends of the fixed frame, and the water tank The drain means is detachable from the opening on the side of the main body case, the fixing frame is a polyolefin resin, and the thickness of the water tank is reduced. It is intended to reduce weight.

  That is, since the handle and the water tank are connected via the fixed frame, the impact from the handle is transmitted to the connection part between the handle and the fixed frame, and further transmitted to the connection part between the fixed frame and the water tank.

  First, since the fixed frame is a polyolefin-based resin, it is deformed when an impact is applied, and the impact is absorbed by deformation, so that the generation of cracks is suppressed.

  Next, since the fixed frame is fixed in a U shape so as to cover the bottom surface and both side surfaces of the water tank, the U shape is maintained by the water tank, and the fixing frame and the water tank Since the impact transmitted to the connecting portion is received by the bottom surface and both side surfaces of the water tank, stress concentration is unlikely to occur, and as a result, cracks due to the impact are less likely to occur.

  Based on these results, the water tank can be made thinner and lighter.

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