On the other hand, a plurality of free casters 25 are provided on the bottom surface of the base panel portion 22, and a discharge port portion 2 e opened in a mesh shape is provided at the rear portion of the cover panel portion 23. Further, the upper front panel portion 24u is provided with a suction port portion 2i opened in a mesh shape, and a controller unit mounting portion 26 including an operation panel such as a power switch, a timer, and a setting portion is secured next to the suction port portion 2i. When the cabinet 2 is assembled, the form shown in FIG. 1 is formed, and a space surrounded by the cabinet 2 is formed therein.

  On the other hand, 27 is an internal frame. The inner frame 27 is bent into a U-shape in plan view, thereby partitioning the interior of the cabinet 2 with a partition surface 27s and a right support surface 27p and a left support surface extending forward from both sides of the partition surface 27s. 27q is integrally formed. The internal frame 27 is disposed inside the cabinet 2 and partitions the interior of the cabinet 2 forward and backward to form a front chamber Rf and a rear chamber Rr each having a volume of about half.

  In addition, a circular opening 27o is formed in the upper half of the partition surface 27s, and the blower fan 3 is attached to the opening 27o. In this case, as shown in FIG. 1, the blower fan 3 is mounted on the rear surface of the partition surface 27 s by the mounting bracket 28 and is disposed coaxially with the opening 27 o. Thus, the partition surface 27s supports the blower fan 3 facing the opening 27o. When the blower fan 3 is activated, the partition surface 27s sucks outside air A from the suction port 2i of the cabinet 2 and from the discharge port 2e. Can be released. On the other hand, attachment plate portions 29p and 29q are integrally formed respectively on the upper half of the front end of the right support surface 27p and the left support surface 27q, and both sides of the dehumidifying cooler 4 are attached to the attachment plate portions 29p and 29q. . Thereby, the cooler 4 is arrange | positioned in the ventilation path Dw of the ventilation fan 3 mentioned above.

  Further, both sides of the drying condenser 30 are attached to the front surface of the partition surface 27s. Thus, the inner frame 27 supports the cooler 4 by the right support surface 27p and the left support surface 27q, and supports the condenser 30 by the partition surface 27s. The condenser 30 is disposed in front of the cooler 4 in the blowing direction (F direction). On the other hand, a compressor 31 is installed on the base panel portion 22 in the rear chamber Rr. The cooler 4, the condenser 30 and the compressor 31 described above constitute a refrigeration cycle in which refrigerant circulates together with a dryer, a capillary tube, an accumulator, and the like (not shown).

  On the other hand, 5 is a drain collecting drain pan arranged horizontally, and it is possible to collect the drain W that is located below the cooler 4 and hangs down from the cooler 4. The drain pan 5 has a bottom surface portion 5m formed in a rectangular shape and four side surface portions 5s that are raised at right angles from four sides of the bottom surface portion 5m, and a drain port portion 5e is provided at a predetermined position of the bottom surface portion 5m. Provide. The bottom surface portion 5m may be formed by a horizontal flat surface, or may be formed by an inclined surface through which the drain W flows to the drain port portion 5e. The drain port portion 5e is formed in a pipe shape and protrudes downward from the lower surface of the bottom surface portion 5m at a right angle, and the upper end port of the drain port portion 5e is opened on the upper surface 5u of the bottom surface portion 5m. Thereby, the drain (drain water) W on the upper surface 5u is discharged downward through the drain port portion 5e. In this case, the inner diameter of the drain port portion 5e is selected, and it is considered that the drain W flows smoothly even when passing through the chain member 6 described later, and the diameter is not increased more than necessary.

  Further, the drain pan 5 is supported so as to be slidable in the horizontal direction by rail portions 11p and 11q attached to the apparatus main body 1m. In this case, a pair of rail members 41, 41 bent in an L shape is prepared, and the vertical plate portions of the rail members 41, 41 are connected to the right support surface 27p and the left support surface of the inner frame 27 as shown in FIG. By fixing each to the inner surface of 27q, it is possible to provide rail portions 11p, 11q that protrude horizontally inward from the inner surfaces of the right support surface 27p and the left support surface 27q. Thereby, while being able to place the lower surface both sides position of the bottom face part 5m of the drain pan 5 on the upper surface of the rail parts 11p and 11q, the drain pan 5 can be slid back and forth. Therefore, the drain pan 5 can be attached to the apparatus main body 1m by being pushed in, and can be detached from the apparatus main body 1m by pulling out the drain pan 5.

  In this way, if the drain pan 5 is supported by the rail portions 11p and 11q provided in the apparatus main body 1m so as to be slidable in the horizontal direction, the drain pan 5 can be easily attached to and detached from the apparatus main body 1m. Even when the valve body 7 is suspended by the chain member 6, the valve body 7 can be pulled up by the chain member 6 when the drain pan 5 is removed. Therefore, the chain member 6 and the valve body 7 do not interfere with the removal of the drain pan 5, and the drain pan 5 can be attached and detached smoothly and reliably.

  Further, a chain member 6 is prepared, and a valve body 7 using a spherical body 7s formed of an elastic material is fixed to one end of the chain member 6. In this case, the chain member 6 is preferably made of metal, but is not necessarily made of metal, and does not exclude the chain member 6 made of other materials such as synthetic resin. The spherical body 7s uses a general rubber ball, and the diameter of the spherical body 7s is selected such that the lower end port 5eo can be closed when it contacts the lower end port 5eo of the drain port portion 5e. Thus, since a general rubber ball can be utilized for the valve body 7, it can implement easily and at low cost. The other end side of the chain member 6 with the valve body 7 fixed to one end passes through the inside of the drain port portion 5e from the lower end port 5eo of the drain port portion 5e and reaches the upper surface 5u side of the drain pan 5, and the chain member As shown in FIGS. 3 and 4, the other end (upper end) of 6 is fixed to a chain fixing portion 42 provided integrally with the upper end of the corner portion 5 ss on the near side of the drain pan 5. Thereby, even when the drain pan 5 is mounted at the mounting position Xds of the apparatus main body 1m, a part of the chain member 6 positioned on the corner 5ss side is positioned in front of the cooler 4, and the user The chain member 6 can be pulled out (pulled up) by hooking it on the finger H of the hand (see FIG. 5B). The length of the chain member 6 is such that the valve body 7 can be hung downward from the lower end port 5eo of the drain port portion 5e via the chain member 6, and can be accommodated in the drain tank 1t through the tank port portion 1ti described later. Select the length. Further, a chain hook 6f protruding upward is fixed to the upper end of the side surface portion 5s located in the vicinity of the corner portion 5ss. Thereby, an arbitrary position of the pulled-out chain member 6 can be hooked on the chain hook 6f.

  On the other hand, a tank storage chamber is provided below the drain pan 5 attached, and the drain tank 1t can be stored in this tank storage chamber. That is, the drain tank 1t can be placed on the upper surface of the base panel portion 22 and loaded, or taken out and unloaded. In addition, the drain tank 1t can utilize the general purpose tank marketed generally. The illustrated drain tank 1t is formed by integrally forming a tank mouth portion 1ti facing obliquely upward on an inclined surface formed on one side of the upper end surface, and a detachable cap (not shown) is attached to the tank mouth portion 1ti. Accompanying.

  Therefore, the position of the drain port portion 5e of the drain pan 5 described above is the position of the tank port portion 1ti at the loading position Xts where the drain tank 1t is loaded into the device main body portion 1m at the mounting position Xds where the drain pan 5 is mounted on the device main body portion 1m. Select so that it is located directly above. Further, the height of the drain pan 5 is selected such that it can slide on the rail portions 11p and 11q in a state where the valve body 7 is in contact with the lower end port 5eo of the drain port portion 5e. Thereby, the drain tank 1t can store the drain W which is located under the drain pan 5 and is discharged from the drain port portion 5e of the drain pan 5 at the time of mounting.

  Next, operation | movement (function) of the dehumidification apparatus 1 which concerns on this embodiment is demonstrated with reference to FIGS. 1-5 (a)-(c).

  First, an empty drain tank 1t is loaded into the apparatus main body 1m. In this case, the lower front panel portion 24d may be removed and the drain tank 1t may be placed on the base panel portion 22. At this time, as shown in FIG. 1, since the valve body 7 is suspended from the drain port portion 5e of the drain pan 5 attached to the apparatus main body 1m via the chain member 6, FIG. As shown in FIG. 3, the user raises the valve body 7 by pulling the chain member 6 forward with the finger H or the like from the upper surface 5u side of the drain pan 5, so that the drain tank 1t is not obstructed. . In addition, the chain member 6 in a state of being pulled forward by the finger H is denoted by reference numeral 6s. When the drain tank 1t is loaded, the chain member 6 is returned and the valve body 7 is lowered to be accommodated in the tank port 1ti of the drain tank 1t. At this time, the drain tank 1t is aligned so that the chain member 6 is positioned substantially at the center of the drain port portion 5e.

  Thus, even when the drain tank 1t having the tank port 1ti is used as the drain tank 1t, the chain member 6 suspended from the drain port 5e is put into the drain tank 1t through the tank port 1ti. Since it accommodates, the tank port part 1ti can be easily aligned with the drain port part 5e. That is, when the inclined tank mouth portion 1ti as illustrated is viewed from directly above, the substantial diameter (area) of the tank mouth portion 1ti is reduced, but it is easy by aligning the chain member 6 as a guide. Can be aligned. Moreover, even if the diameter (area) of the tank port 1ti is small, the drain W flows down along the chain member 6, so that it can be reliably guided into the tank port 1ti and further into the drain tank 1t. it can. Therefore, in particular, it is possible to avoid the problem that the drain W leaks to the outside of the drain tank 1t even when the tank opening 1ti is small.

  When the drain tank 1t is loaded, the lower front panel portion 24d is attached. And in order to start use, the operation switch of the dehumidification apparatus 1 is turned ON. Thereby, the refrigerating cycle (compressor 31) and the ventilation fan 3 operate | move. The cooler 4 is cooled by the operation of the refrigeration cycle, and the operation of the blower fan 3 causes the outside air (air) A to be sucked into the interior of the cabinet 2 from the suction port 2i of the upper front panel unit 24u. It is discharged to the outside through the discharge port 2e through Dw.

  At this time, since the cooling unit 4 and the condenser 30 are disposed in the air passage Dw, the outside air A passing through the air passage Dw is first cooled by the cooling unit 4. When the outside air A is cooled (heat exchange) by the cooler 4, supersaturated water in the outside air A is removed. Then, as shown in FIG. 5 (a), the removed water becomes drain W, hangs down from the cooling unit 4 onto the drain pan 5, is recovered, and is further discharged from the drain port 5e to be drain tank 1t. (Stored). When the drain W is discharged from the drain port 5e, it flows down through the chain member 6 and is stored in the drain tank 1t through the tank port 23. Therefore, even when the tank opening 1ti is small, it is possible to avoid the problem that the drain W leaks outside the drain tank 1t. The outside air A that has passed through the cooler 4 is slightly warmed by passing through the condenser 30, and after the outside air A has been dried, it is upwardly, backwardly, rightward and leftward from the plurality of discharge ports 2e. Will be released.

  On the other hand, when the drain tank 1t becomes full by use, after removing the lower front panel portion 24d, the drain tank 1t is taken out from the apparatus main body 1m, and the drain W stored in the drain tank 1t is discarded. . At this time, since the valve body 7 suspended by the chain member 6 is accommodated (residual) in the drain tank 1t, the user can bring the chain member 6 forward with the finger H or the like from the upper surface 5u side of the drain pan 5. By pulling and raising the valve body 7, as shown in FIG. 5 (c), the lower end 5eo of the drain port portion 5e is closed by the valve body 7 and the chain member 6 is hooked on the chain hook 6f. As a result, the closed state of the lower end opening 5eo is maintained, which does not interfere with the removal of the drain tank 1t, and it is possible to avoid the problem that the drain W droops from the lower end opening 5eo even after the removal.

  On the other hand, when the drain pan 5 is washed after use for a predetermined period, after removing the upper front panel portion 24u, the user can hook it on the finger H as shown in FIG. By pulling out the chain member 6 and raising the valve body 7, the lower end 5 eo of the drain port portion 5 e is closed by the valve body 7. As a result, dripping of the drain W from the drain port portion 5e is prevented, and in this state, as shown in FIG. 5 (c), the drain pan 5 can be easily pulled out by sliding on the rail portion 11p. Can be taken out to the outside. Then, the drain pan 5 can be taken to a predetermined cleaning place and cleaned using a cleaning brush, a detergent or the like. Moreover, the drain pan 5 after washing | cleaning can be mounted | worn by performing the procedure reverse to the procedure at the time of taking out.

  Therefore, according to the dehumidifying apparatus 1 according to this embodiment, the valve body capable of closing the drain port portion 5e when the chain member 6 is pulled up to the lower end of the chain member 6 passed through the drain port portion 5e. 7 is attached, for example, when using in a dusty environment, the drain pan 5 is removed from the main body 1m of the apparatus, and even when cleaning is performed, the drain pan 5 is removed by the valve body 7 when the drain pan 5 is removed. The part 5e can be closed. Therefore, it is possible to prevent unnecessary dripping of the drain W from the drain port portion 5e when removing the drain pan 5, and to improve the overall workability and further improve the work efficiency when cleaning the drain pan 5. .

  Next, the dehumidification apparatus 1 which concerns on the modified embodiment of this invention is demonstrated with reference to Fig.6 (a)-(c).

  FIG. 6A shows the valve body 7 using a cone 7d formed of an elastic material. Also in this case, since a simple block body can be used, it can be implemented easily and at low cost. Moreover, while the drain port part 5e is formed with a pipe member, the example which made the inside diameter small by inserting the adjustment block 45 inside is shown.

  FIG. 6B shows that the valve body 7 is closed by the hinge portion 12 at the lower end 5ed of the drain port portion 5e so as to close the drain port portion 5e at the closed position Pc and open the drain port portion 5e at the open position Po. It is configured to be pivotably attached. Accordingly, the valve body 7 can be formed of a relatively thin plate material, and a reliable and stable opening / closing operation can be performed on the valve body 7.

  FIG. 6C shows the chain member 6 with a cleaning brush member 13 attached thereto. Thereby, it is possible to clean the inside of the drain port 5e and further clean the upper surface 5u of the drain pan 5 by using the brush member 13, which contributes to improvement in convenience and ease of cleaning during cleaning. it can. 6 (a) to 6 (c), the same parts as those in FIGS. 1 to 4 are denoted by the same reference numerals to clarify the configuration, and detailed description thereof is omitted.
