Description

  The present invention relates to a guide member. More specifically, the present invention relates to a guide member that guides a cylindrical body such as a tube or a hose for discharging condensed water from a drain pan of an air conditioner.

  Condensate collected in the drain pan of the air conditioner is discharged outside the machine by a drain pump during normal operation, but drains that seal the drain port formed on the bottom of the drain pan during maintenance of the device It is necessary to remove the stopper (drain cap) and discharge the condensed water remaining in the drain pan.

  As such a drain plug, various things other than the drain plug made of an elastic material that press-fits into the drain port and seals the drain port have been proposed. For example, Patent Document 1 proposes a drain plug of a type in which a small-diameter discharge hole is formed in the center of a large-diameter drain plug and the discharge hole is sealed with a drain plug. After removing the drain plug that seals the discharge hole, the condensed water is discharged by connecting a drain hose to the connection port provided in the drain plug.

  In addition, Patent Document 2 proposes a screw-type drain plug that uses a valve mechanism. In this drain plug, the drain port is sealed by screwing the drain plug, and the drain is reversely drained. The valve is opened by loosening the plug, and drainage is performed from the passage in the center of the drain plug. And at the time of drainage, a drain plug is loosened in the state which connected the hose beforehand to the exit of the central passage.

(Guide member)
Next, an embodiment of the guide member of the present invention will be described.
FIG. 4 is a perspective explanatory view of the guide member 60 according to the first embodiment of the present invention, and FIG. 5 is a main part of the air conditioner in which the guide member 60 shown in FIG. It is explanatory drawing.

  The guide member 60 has a rectangular base plate 61 sized to cover the rectangular inspection port 4 formed on the side wall 1 b of the casing 1, and positioning means and a guide passage 64 are provided on the base plate 61. Yes. The guide member 60 can be manufactured by integral molding of a synthetic resin such as ABS resin, but can also be manufactured by separately manufacturing each element and connecting them by adhesion or the like. In the case of integral molding, the guide member 60 can be easily manufactured, and the number of parts can be reduced.

  The positioning means is a means for holding the guide member 60 at a predetermined position. In the present embodiment, the positioning means is a short angle projecting substantially at the center of the inner surface 61a of the base plate 61 (the surface that contacts the casing 1). It consists of a cylindrical body 62. The outer shape of the short tube 62 is set to be slightly smaller than the size of the inspection port 4. The guide member 60 can be easily held at a predetermined position simply by inserting the short-angle cylinder 62 into the inspection port 4, and as a result, a cylinder such as a tube, which will be described later, is inserted through the guide passage 64. It can be kept in place.

  A lower wall 62a of the short tube 62 that contacts the lower edge 4a of the inspection port 4 extends inward from the center in the left-right direction X (see FIG. 4) of the tip 62a1 of the lower wall 62a. An L-shaped locking portion 63 is formed which includes a horizontal portion 63a provided and a vertical portion 63b extending downward from the tip of the horizontal portion 63a. By restricting the vertical portion 63b of the locking portion 63 to the inner surface of the heat insulating member 3 disposed on the inner surface of the casing 1, the movement of the guide member 60 in the front-rear direction Y (see FIG. 4) is restricted. Can do.

  As shown in FIG. 5, the casing side wall 1 b slightly above the inspection port 4 is provided with a fastener 71 that is rotatable around a shaft 70 erected on the casing side wall 1 b. The fastener 71 is attached to the shaft 70 so as to be separated from the casing side wall 1b by the thickness of the base plate 61. After the guide member 60 is attached to the casing 1, the fastener 71 is rotated to rotate the base plate 61. By engaging with the upper edge portion, the movement of the base plate 61 in the front-rear direction Y can be more reliably regulated.

  An insertion hole 65 is formed at a position slightly above the center in the left-right direction of the base plate 61, and a guide passage 64 is connected to the insertion hole 65. The guide passage 64 includes a curved pipe portion 64a connected to the insertion hole 65 and a distal straight pipe portion 64b connected to the distal end side of the curved pipe portion 64a.

  As shown in FIG. 5, the distal end straight pipe portion 64 b of the guide passage 64 faces the bottom surface 40 a of the drain pan 40, more specifically, the bottom surface 40 a of the drain pan 40 below the drain pump 50. The guide passage 64 is set in a shape and size so that the tip of the guide passage 64 does not contact the drain pump 50 or the like when the guide member 60 is attached to the inspection port 4.

Next, an example of a method for discharging condensed water from the drain pan 40 using the guide member 60 described above will be described.
First, when the air conditioner is in operation, the inspection port 4 on the side wall 1b of the casing 1 is closed by the inspection lid 5 as shown in FIG.

  When discharging the condensed water in the drain pan 40, first, the operation of the air conditioner is stopped. Next, the corner cover 13 of the decorative panel 10 is removed, and the inspection lid 5 of the inspection port 4 positioned above the corner cover 13 is further removed. Then, the guide member 60 shown in FIG. 4 is slightly inclined toward the front side, and attached to the inspection port 4 so that the locking portion 63 contacts the lower edge 4a of the inspection port 4. Next, with the inner surface of the base plate 61 in contact with the side wall 1 b of the casing 1, the fastener 71 is rotated and engaged with the upper edge of the base plate 61. In this state, the short cylinder 62 projecting from the inner surface of the base plate 61 contacts the edge of the inspection port 4, so that the guide member 60 is positioned in the horizontal direction X and vertical direction Z (see FIG. 4). Can do. Further, since the vertical portion 63b of the locking portion 63 is locked to the inner surface of the heat insulating member 3 disposed on the inner surface of the casing 1, the guide member 60 can be positioned or fixed in the front-rear direction Y. Furthermore, since the fastener 71 is engaged with the base plate 61, the guide member 60 can be positioned or fixed in the front-rear direction Y more reliably. Thus, since the guide member 60 can be reliably held at a predetermined position, insertion of a tube or the like into the guide passage 64 is facilitated, and the tube can be guided to a predetermined location.

  After the guide member 60 is attached to the inspection port 4, the tubular tube 80 is inserted from the insertion hole 65 of the guide plate 61. Since the tube 80 is flexible, the tube 80 moves along the curved pipe portion 64 a and the straight end pipe portion 64 b of the guide passage 64, and the tip thereof reaches the vicinity of the bottom surface 40 a of the drain pan 40. More specifically, it reaches the vicinity of the bottom surface 40 a of the drain pan 40 below the drain pump 50, which is the lowest portion of the drain pan 40.

  Subsequently, the condensed water in the drain pan 40 can be drained by the principle of siphon by simply sucking the inside of the tube 80 once using an appropriate suction device or the like. In this case, since the tip of the tube 80 reaches the vicinity of the bottom surface 40a of the drain pan 40 below the drain pump 50, which is the lowest portion of the drain pan 40, the condensed water in the drain pan 40 can be drained until it is almost completely eliminated. it can.

  After draining the condensed water, as shown in FIG. 6, the fiber scope 81, which is a flexible cylinder, is inserted into the guide passage 64 and the inside of the drain pan 40 is inspected.

  As a result of inspection, if it is found that a lump or slime such as dust adheres to the bottom surface 40a of the drain pan 40, the fiberscope 81 is once pulled out from the guide passage 64, and a water injection tube is inserted into the guide passage 64. (Not shown) is inserted. Then, cleaning water is poured into the drain pan 40 from the water injection tube to clean the lump of dust and slime. After the cleaning, the cleaning water remaining at the bottom of the drain pan 40 is discharged out of the machine by the tube 80 inserted into the guide passage 64 instead of the water injection tube. This cleaning process is repeated several times depending on the degree of contamination. Finally, the fiberscope 81 is inserted again into the guide passage 64 and the inside of the drain pan 40 is reinspected.

  In addition, in the case where lump of dust or slime adheres so much that it cannot be cleaned by pouring of cleaning water, for example, the drain pan 40 can be removed from the air conditioner and cleaned.

When it is confirmed by the fiberscope 81 that the inside of the drain pan 40 is not dirty, the guide member 60 is removed from the inspection port 4, and then the inspection port 4 is closed with the inspection lid 5, and then the corner cover 13 is attached to the decorative panel 10. Installation is completed by attaching.
Note that when the guide member 60 is removed from the inspection port 4, a bag body containing the antibacterial material may be put into the drain pan 40 from the inspection port 4.
