  In the drainage tank of such a conventional dehumidifying device, the condensed drain water is transmitted through the back surface of the drain pan 107 under conditions where condensation tends to occur, such as in a continuous high humidity state, and is not collected in the drain tank 102, and the floor If the shape of the drainage tank 102 is U-shaped so as to surround the compressor, a drainage port should be provided on one of the two protrusions. Therefore, it is difficult to tell which drain outlet is located, and when draining with the projection part serving as the drain outlet down, water may leak from the other projection part, and the draining operation is inconvenient Therefore, it is required that the drain water condensed on the back surface of the drain pan 107 is always collected in the drain tank and can be easily drained.

  Further, when draining, it is necessary to remove the small lid 105 and open the drainage port 103, and when removing the small lid 105, the fitting force is weakened so that the large lid 104 does not come off together. Sometimes, the small lid 105 is easily lost, and when the vibration of the operation, the movement of the main body 101 or the drainage tank 102 is pulled out, the small lid 105 is detached to wet the surroundings, or the drainage tank 102 is not easily detached due to being caught by the main body 101. Therefore, there is a demand for an easy-to-use drainage tank that does not leak from the drainage tank and that part of the lid is not lost.

  The present invention solves the above-mentioned problems, and prevents drain water from leaking from the gap between the drain hole and the lid when attaching to and detaching from the main body of the drain tank, during transportation, and in drainage work, and is easy to use. The purpose is to provide a drain tank for the dehumidifier.

(Embodiment 1)
As shown in FIGS. 1 to 6, the main body 101 of the dehumidifying device is dehumidified when the evaporator 111 is cooled and condensed by the operation of a refrigeration cycle 113 including a blower (not shown) and the evaporator 111. A drain pan 107 that collects the dehumidified water and guides it to the drain tank 1 is configured between the evaporator 111 and the drain tank 1. The drain tank 1 is provided with a tank case 3 having an opening 2 at the top and a lid 5 that covers the opening 2 in a detachable manner.

  The shape of the opening 2 of the tank case 3 disposed under the drain pan 107 is a shape that substantially covers the entire size of the lower surface of the evaporator 111 when seen through a plane, and the back side of the drain pan 107 cooled by the evaporator 111. It is set as the shape which can receive the drain water dripped from.

  Further, as shown in FIGS. 3 and 4, a flat flat side wall 6 is provided on the left side surface of the tank case 3, and a drainage convex portion 8 extending from the flat side wall 6 and protruding from the back surface 7 of the tank case is integrated. Is formed.

  Moreover, as shown in FIGS. 1-3, the groove | channel part 9 which engages with the upper end side of the tank case 3 provided in the outer periphery of the lid | cover 5 so that attachment or detachment is possible, and the lid | cover provided in the lid | cover 5 corresponding to the drainage convex part 8 A convex portion 10 is formed, a hinge portion 11 is formed across the lid convex portion 10, and a groove portion 9 is provided in the lid convex portion 10 so that the drain convex portion 8 can be opened and closed. Further, the drain pan 107 is provided with a guide 12 for closing the lid convex portion 10.

  Further, as shown in FIG. 5, the position of the drain hole 4 formed in the lid 5 is provided in front of the center of the lid 5 with respect to the attaching / detaching direction so that water droplets can be prevented from scattering from the drain hole 4. Yes.

  Further, as shown in FIG. 6, the bottom surface of the drainage convex portion 8 is formed as the drainage bottom surface 13, the drainage bottom surface 13 is formed above the bottom surface of the tank case 3, and between the drainage bottom surface 13 and the bottom surface of the tank case 3. The curved surface portion 14 is provided.

  In the above configuration, the dehumidified water generated in the evaporator 103 and the lower surface of the drain pan 107 are easily condensed by being cooled by the evaporator 103. In particular, dew condensation is formed on the lower surface of the drain pan 107 that is close to or in contact with the lower portion of the evaporator 103 and drops as water droplets, but the opening 2 of the tank case 3 substantially covers the entire lower surface of the evaporator 103. Since it is received, the dripped drain water can be collected in the drain tank 1.

  In addition, since the drainage convex portion 8 is a part of the opening 2 for collecting drain water of the drain pan 107 below the evaporator 103, the drainage port is easily recognized in shape, and the side space of the compressor 108 is drained. It can be used for the convex portion 8, and when the drainage convex portion 8 is lowered as shown in FIG. 4, the tank case 3 has no place for water accumulation, and water is discharged from other than the drainage convex portion 8 as indicated by an arrow. It can be drained smoothly.

  Further, in the state where the lid convex portion 10 is closed, the lid convex portion 10 can be reliably fixed by the hinge portion 11 and the groove portion 9, so that water does not leak from the lid convex portion 10. Furthermore, in the state where the lid convex portion 10 is opened, the hinge portion 11 is integrated with the lid 5, so that the drainage can be conveniently performed without dropping or removing the lid portion as compared with the conventional case.

  Further, when the drainage tank 1 is inserted into the main body 101 of the dehumidifying device in a state where the lid convex portion 10 is not completely closed, the upper surface of the lid convex portion 10 is pushed down along the inclined curved surface of the guide 12. The convex portion 10 can reliably close the upper surface of the drainage convex portion 8 and can prevent water leakage from the drainage convex portion 8. At the same time, even if there is vibration due to force majeure after the drain tank 1 is inserted into the main body 101, the lid convex portion 10 is pressed by the guide 12 so as not to float up, and water leakage does not occur. Furthermore, it is possible to prevent the lid convex portion 10 from being caught by another portion and the drainage tank 1 from becoming difficult to come off.

  Next, since the position of the drain hole 4 formed in the lid 5 is provided on the near side from the center of the lid 5 with respect to the attaching / detaching direction, the drain hole 4 can keep a distance from the tank case back surface 7. When the drainage tank 1 is pulled out, it is possible to prevent the water splashing up against the tank case back surface 7 from jumping out from the drain hole 4. Moreover, since it is near the center of the tank, it is possible to suppress water splashing from the drain hole 4 even when it is carried.

  Furthermore, in this embodiment, since the drain hole 4 is provided behind the lid convex portion 10, the tank wall surface is not perpendicular to the pull-out direction, so that the rebound direction is shifted and the distance from the wall is also increased. Therefore, it is possible to make it difficult for water to escape from the drain hole 4.

  Further, since the bottom surface of the drainage convex portion 8 is formed as the drainage bottom surface 13 and the drainage bottom surface 13 is formed above the bottom surface of the tank case 3, even when the drainage tank 1 is placed on a flat surface such as a floor, Since the bottom surface 13 is at a position floating from the floor surface, it is easy to put the hand and hold the drain tank 1.

  Further, by providing a curved surface portion 14 that is tangent between the drain bottom surface 13 and the bottom surface of the tank case 3, when the drain tank 1 is inserted into the main body 101, the bottom surface is a tangent curved surface because the clearance in the vertical direction is large. Or since it is an inclined surface, the position can be gradually regulated and fitted by sliding it as it is.

(Reference example)
As shown in FIGS. 7-11, it has the protrusion 18 formed in the side surface of the rotating shaft 17 of the handle 16, and the reinforcing rib 19 formed in the upper part of the shaft hole 15 of the tank case 3, , The protrusion 18 of the rotating shaft 17 is close to the reinforcing rib 19.

  Further, as shown in FIG. 8, the tip 20 of the protrusion 18 provided on the rotating shaft 17 is a curved surface having a radius of curvature larger than the distance from the center of the rotating shaft 17 to the tip 20.

  Further, as shown in FIG. 9, a downward recess 21 is formed in the reinforcing rib 19, and the tip 20 of the protrusion 18 of the rotating shaft 17 can be engaged with the recess 21.

  As shown in FIG. 10, a small hole portion 22 is formed at the center of the rotation shaft 17 of the handle 16, and a reinforcing metal fitting 23 that can be fitted into the small hole portion 22 is provided.

  Further, as shown in FIG. 11, when the regulation rib 24 is provided on the lid 5 and the handle 16 is tilted to the upper surface of the lid 5, the regulation rib 24 is close to the attachment portion 26 other than the handle portion 25 of the handle 16. This makes it difficult to lift the attachment 26 and makes it easy to lift only the handle 25 of the handle 16.

  In the above configuration, the drain tank 1 is normally supported by the protrusion 18 of the handle 16. However, when the water is full or an impact is applied, the drain tank 1 and the handle 16 are deformed due to distortion, and the drain tank 1 is supported by both the rotating shaft 17 and the protrusion 18 of the handle 16. And when load increases, a support location increases and an intensity | strength can be increased by disperse | distributing stress.

  In addition, since the tip 20 of the protrusion 18 provided on the rotating shaft 17 is a curved surface having a radius of curvature larger than the distance from the center of the rotating shaft 17 to the tip 20, when the drain tank 1 is full, Since the tip portion 20 of the projection 18 that contacts the flat surface of the reinforcing rib 19 is larger than the radius of the rotation axis, when the handle 16 rotates from the vertical direction, a force A is generated to return to the original vertical direction. The drain tank 1 is prevented from shaking. Here, the action increases as the weight of the drain tank 1 increases, and it can be handled more stably.

  Further, as shown in FIG. 9, even if a concave portion 21 is formed on the reinforcing rib 19 so that the tip portion 20 of the projection portion 18 of the rotating shaft 17 can be engaged with the concave portion 21, the handle 21 is similarly formed. 16 is gently fixed vertically to prevent the drain tank 1 from shaking. Here, the action increases as the weight of the drain tank 1 increases, and it can be handled more stably.

  Further, since the reinforcing metal fitting 23 is inserted into the small hole portion 22 formed at the center of the rotating shaft 17 of the handle 16, it can be reinforced with the reinforcing metal fitting 23 in accordance with a change in the set load applied to the shaft of the handle 16. it can.

  Further, when the handle 16 is tilted to the upper surface of the lid 5, the restricting rib 24 makes it difficult to lift the appendage 26 and only the handle 25 of the handle 16 is easily lifted. It is possible to prevent erroneous use such as having an attachment portion 26 other than the handle portion 25 provided due to factors such as the above, and to promptly hold the handle 16.

  In this embodiment, a dehumidifier using a refrigeration cycle is used. However, a dehumidifier using an inorganic adsorption-type hygroscopic agent such as silica gel or zeolite, or a dehumidification apparatus combining a refrigeration cycle and an adsorption-type hygroscopic agent is used. It may be used.

  In addition, refrigerants for the refrigeration cycle include HCFC refrigerants (including chlorine, hydrogen, fluorine, and carbon atoms in the molecule), HFC refrigerants (including hydrogen, carbon, and fluorine atoms in the molecule), carbonization Hydrogen, carbon dioxide, or the like can be used.

  As described above, the drainage tank of the dehumidifying apparatus according to the present invention can prevent water leakage with a simple configuration, can easily perform drainage work, and can conveniently operate the handle used for transportation, so that drain water is generated. It is suitable for use as a drainage tank for collecting wastewater from equipment and transporting and discharging the collected wastewater.
