By grasping the handle 27, the user can remove the garbage basket 24 from the opening 13 side. It can be attached to and detached from the inside of the vertical pipe portion 16.

  As shown in FIGS. 3 and 4, a female screw portion 22 into which a male screw portion 21 formed at the front end portion of the horizontal tube 14 is screwed is provided at the rear end portion of the bent pipe portion 17. The ring-shaped connection part 23 formed in this is formed, and the connection port is formed in this connection part 23 (refer FIG. 4). That is, in this embodiment, the drainage pipe of the present invention is constituted by the main body of the drainage trap 15 composed of the vertical pipe part 16 and the bent pipe part 17 and the horizontal pipe 14, and the main body of these drainage traps 15. And the horizontal pipe 14 are configured separately, so that the drain pipe can be easily arranged in the refrigerated showcase.

  In this embodiment, the horizontal pipe 14 and the bent pipe part 17 are connected by the male screw part 21 and the female screw part 22, but in addition to this, the female screw part 22 is formed on the bent pipe part 17. Instead, the horizontal pipe 14 and the bent pipe part 17 are connected by applying an adhesive or the like to the connecting part 23 or by providing an annular packing on the outer periphery of one end of the horizontal pipe 14 and press-fitting into the connecting part 23. It is good also as composition to do.

  As shown in FIG. 2, on the inner surface of the bent tube portion 17, a ridge 28 that abuts a sealing plate 33 as a storage plate, which will be described later, extends in the vertical direction. Specifically, the ridge 28 extends from the bottom of the bent tube portion 17 to the upper circular drainage port 29 formed in the communicating portion with the vertical tube portion 16 in the bent tube portion 17 in a front view. It is formed in a letter shape.

  As shown in FIG. 5, the drainage port 29 formed between the vertical pipe part 16 and the bent pipe part 17 is formed with a smaller diameter than the opening 13, and the drainage port 29 has a disk-shaped lid. The member 30 is fitted and closed. A knob 31 is provided on the upper surface side of the lid member 30 so that the user can remove the lid member 30 from the opening 13 by gripping the knob 31.

  On the lower surface of the lid member 30, as shown in FIG. 2, a deodorizing plate 32 as a deodorizing member in this embodiment and a sealing plate as a storage plate in this embodiment having a lower end extending below the deodorizing plate 32. A water plate 33 is formed integrally with the lid member 30. Thus, the deodorizing plate 32, the sealing plate 33, and the lid member 30 are integrally formed, so that the number of parts of the drain trap 15 is reduced and the manufacturing cost of the drain trap 15 is suppressed.

  The sealing plate 33 has a half-moon shape, and the shape (curvature) of the outer peripheral edge of the sealing plate 33 is the same as the shape (curvature) of the inner periphery of the bottom of the bent tube portion 17. The outer peripheral edge is in contact with the inner peripheral surface of the bottom of the bent tube portion 17. Moreover, it connects with the cover member 30 by the connection piece 33a extended toward upper direction from the upper-end part right-and-left side of the sealing plate 33, and between these right-and-left connection pieces 33a and 33a, it becomes the waste water storage part (alpha) mentioned later. An outflow hole 34 is formed for allowing the stored wastewater to flow out to the sewer side.

  In addition, an inflow port 35 through which the waste water that has flowed into the vertical pipe portion 16 flows into the bent pipe portion 17 is formed in front of the deodorizing plate 32 in the lid member 30. The inflow port 35 is smaller than the drainage port 29 and includes a plurality of slits (see FIG. 5). The slit-shaped inflow port 35 holds the dust that has passed through the garbage basket 24. It has become. The inflow port 35 is formed at a position on the front side of the deodorizing plate 32 in the lid member 30, and the drainage flowing down from the inflow port 35 falls on the front side of the deodorizing plate 32.

  Further, as shown in FIG. 5, at the left and right ends of the lid member 30, a predetermined length of recess 36 that fits above the above-described protrusion 28 is extended in the vertical direction (see FIG. 4). ) When the disc-shaped lid member 30 is disposed in the drain outlet 29, the recess 36 having a predetermined length is fitted to a part of the projection 28, so that the rear peripheral edge of the sealing plate 33 is convex. Since it is held in contact with the front surface of the strip 28, water leakage due to the separation of the sealing plate 33 from the convex strip 28 is prevented. In addition, it is preferable to provide packing in the contact surface with the front surface of the protruding item | line 28, ie, the back surface peripheral part of the water-sealing board 33, By doing in this way, water leakage is prevented effectively.

  As shown in FIGS. 3 and 4, when the lid member 30 is attached to the drainage port 29, the rear peripheral edge of the sealing plate 33 abuts against the front surface of the ridge 28, so that the sealing plate 33 A substantially lower half in the bent pipe portion 17 is partitioned into an upstream side and a downstream side. That is, the bent inner surface 17a of the bent tube portion 17 and the water sealing plate 33 form a drainage storage portion α in which wastewater that flows into the bent tube portion 17 is stored. Therefore, the drainage flowing into the vertical pipe portion 16 from the opening 13 flows into the bent pipe portion 17 via the inlet 35 disposed on the front side of the lid member 30 and is bent by the sealing plate 33. It is stored in a drainage storage part α formed on the front side in the part 17.

  Since the lower end of the deodorizing plate 32 is formed at a position lower than the upper end of the sealing plate 33, the lower end of the deodorizing plate 32 is stored in the drainage water stored in the drainage storage part α formed by the sealing plate 33. The deodorizing plate 32 partitions the drainage storage part α into the drainage inflow side and the outflow side. Therefore, a sealed part is formed by the drainage stored in the drainage storage part α, the deodorizing plate 32 and the lid member 30, and the internal space of the bent pipe part 17 is blocked on the upstream side and the downstream side. The passage of odor from the side is blocked, and the outflow of cold air flowing from the refrigerator compartment 8 and the ventilation path 4 through the opening 13 is blocked.

  Further, as shown in FIG. 4, the sealing plate 33 is arranged on the front side in the bent tube portion 17, specifically, vertically below the drain port 29, so that the sealed plate 33 is connected to the bent tube portion 17 and the horizontal tube 14. The sealing plate 33, that is, the lid member 30 can be easily attached and removed from above the opening 13 and the drainage port 29.

  As described above, in the refrigerated showcase 1 as an embodiment of the present invention, only the sealing plate 33 and the deodorizing plate 32 are arranged in the bent pipe portion 17 to constitute a part of the drain pipe. In addition to being able to easily form a drain trap (sealed portion) in the bent pipe portion 17, the vertical width of the drain pipe including the main body of the drain trap 15 can be made as short as possible. Since the bottom of the refrigerator compartment 8 formed above the bottom 2a of the housing 2 can be lowered to widen the display space, the drainage storage portion α is formed below the heat insulating member 20. The drainage stored in the drainage storage part α becomes difficult to freeze.

  Further, simply by disposing one sealing plate 33 in the bending pipe portion 17, a drainage storage portion α capable of storing drainage can be easily formed in a space surrounded by the bent inner surface 17a and the sealing plate 33. Therefore, it is possible to easily form the sealed portion, that is, the drain trap 15 without separately providing a member or the like for forming the drain storage portion α, and to be bent to a part of the drain pipe in advance. In the case where the portion is formed, a drain trap can be provided later in the bent portion.

  Further, as shown in FIG. 4, the drainage storage part α is formed at a position lower than the bottom part 2 a of the external housing 2, that is, the heat insulating member 20, and the bent pipe part 17 is formed by the vertical pipe part 16 so that the opening 13 Since it is arrange | positioned in the position away from the opening | mouth 29, it is prevented as much as possible that the waste_water | drain stored in the waste_water | drain storage part (alpha) freezes.

  In addition, a lid member 30 having an inlet 35 smaller than the drain outlet 29 is disposed in the drain outlet 29 formed between the vertical pipe portion 16 and the bent pipe portion 17. Since most of the drainage port 29 is covered with the lid member 30 while draining water into the bent pipe portion 17 from 35, the cold air in the refrigerator compartment 8 becomes difficult to enter the bent pipe portion 17 and enters the drainage storage portion α. The stored waste water becomes difficult to freeze and the outflow of cold air in the refrigerator compartment 8 is also prevented.

  Further, when cleaning the inside of the drain trap 15, the user grasps the handle 27 of the garbage basket 24 to remove the garbage basket 24, picks the knob 31 of the lid member 30, and removes the lid member 30 from the drain outlet 29. By removing, the deodorizing plate 32 and the sealing plate 33 are removed at the same time, and the wastewater stored in the wastewater storage portion α flows out to the sewage side, so that dust and the like accumulated in the wastewater storage portion α can be surely removed. The inside of the bent pipe portion 17 can be cleaned by inserting a cleaning brush or the like through the opening 13 and the drain port 29.

  Furthermore, since water flows from the upper side of the drainage port 29 toward the bent inner surface 17a in the bent pipe portion 17 with a hose or the like, the water flows vigorously along the inclined inner surface 17a. The dirt in the reservoir α can be effectively cleaned.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above embodiment, the drain pipe is constituted by the main body of the drain trap 15 and the horizontal pipe 14, but it may be constituted by a single pipe body having a substantially L shape in side view.

  Further, the sealing plate 33 is disposed immediately below the drainage port 29. However, the sealing plate 33 is disposed at an opening or the like in the connecting portion 23 as long as the drainage storage portion α can be formed using the bent inner surface 17a. May be. Further, such a sealing plate 33 may be disposed in the vicinity of a connection port for connecting the horizontal pipe 14 and used as a regulating plate for regulating the insertion depth of the horizontal pipe 14.

  In the embodiment, the drainage port 29 is formed between the vertical pipe portion 16 in which the garbage basket 24 is accommodated and the bent pipe portion 17. However, the opening 13 formed on the upper surface of the vertical pipe portion 16 is provided. A drain outlet may be used, and the lid member 30 or the like may be disposed in the opening 13 serving as the drain outlet.

It is a vertical side view which shows the refrigerated showcase in an Example. It is a vertical exploded perspective view showing a drain trap. It is a vertical perspective view which shows a drain trap. It is a vertical side view which shows a drain trap. It is a top view which shows the drainage trap of the state which removed the garbage basket.
