Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a drainage device arranged in an indoor unit of an air conditioner.

[0002]

[Prior art]

 The indoor unit of the air conditioner is provided with a drainage device including a drain pan 11 and a drain hose 12 as shown in FIG. 3, for example. The drain pan 11 is for receiving condensed water flowing down from the heat exchanger 13 arranged at the upper part, and has a substantially L-shaped drain port 11a at the lower part, and this drain port 11a collects in the drain pan 11. A drain hose 12 is connected to guide the condensed water to the outside of the room. The outer circumference of the drain hose 12 is covered with a heat insulating material 14 for preventing dew condensation. When connecting the drain hose 12 with the drain port 11a, first fit the end tube 12a of the drain hose 12 over the drain port 11a. After that, the drain hose 12 is fastened by a fastening member 15 to the outer circumference of the heat insulating material 14 of the end pipe portion 12a so that the drain hose 12 does not fall off from the drain port 11a. Further, a heat insulating material 16 for preventing dew condensation is separately attached around the drainage port 11a.

[0003]

[Problems to be solved by the device]

 However, in the case of the combination of the drain pan 11 and the drain hose 12 as described above, the end pipe portion 12a of the drain hose 12 fitted to the drainage port 11a is not directly fastened by the fastening member 15, but rather from the outer circumference of the heat insulating material 14. Since it is indirectly fastened, not only is workability poor, but it is not sufficient as a measure to prevent the drain hose 12 from coming off.For example, if the drain hose 12 is pulled strongly during piping work, etc. There is a risk that the slack will occur, or in the worst case, the drain hose 12 will fall out of the drain port 11a. Therefore, an object of the present invention is to solve these problems and to provide a drainage device for an air conditioner in which the drain pan 11 and the drain hose 12 can be connected more easily and reliably.

[0004]

[Means for Solving the Problems] The present invention has been made to solve the above problems, and collects the condensed water flowing down from the heat exchanger in a drain pan disposed below the heat exchanger. In a drainage device of an air conditioner that discharges to the outside through a drain hose connected to the drain port of the drain pan, a collar is formed on one outer periphery of the drain hose connected to the drain port. At the same time, a hose fixture having a holding portion corresponding to the collar and surrounding one side of the drain hose and the peripheral portion of the drainage port is fixed to the drain pan.

[0005]

[Action]

 With the above configuration, the drain hose has a collar on the outer periphery thereof, and the hose fixing tool has a holding section for holding the collar on the drain hose side, so that the drain hose and the hose fixing tool can be attached at predetermined positions. For example, since the collar on the drain hose side can be clamped by the clamp part of the hose fixing tool, the drain hose can be prevented from coming off from the drain pan, water leakage can be prevented, and the area around the drain port is covered with the hose fixing tool. Since it is exposed, it is possible to prevent dew condensation even without a heat insulating material.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. Fig. 1 shows the components of the drainage system installed in the indoor unit of the air conditioner, and Fig. 2 shows the combined state of these components. In the figure, 1 is a drain pan, 2 is a drain hose, 3 is a hose fixing tool, and 4 is a mounting screw. The drain pan 1 is formed with a main body 1a for receiving condensed water flowing down from a heat exchanger (not shown), a box-shaped water collecting portion 1b integrally formed under the main body, and one side of the water collecting portion 1b. And a drain port (hose connection part) 1c, and two bosses 1d are formed in the lower part of the main body with the drain port 1c interposed therebetween. The drain hose 2 connected to the drain port 1c is made up of a hose body 2a and an end pipe portion 2b connected to the drain port 1c, and a collar 2c is formed on the outer circumference of the end pipe portion 2b. A heat insulating material 5 for preventing dew condensation is covered on the outer peripheral portion except for.

The hose fixture 3 has an open upper surface and one side, and has a holding portion 3a corresponding to the collar 2c on the drain hose 2 side and two screw insertion holes 3b corresponding to the boss 1d on the drain pan 1 side. It is formed so that it can surround the water collecting portion 1b of the drain pan 1 and the end pipe portion 2b of the drain hose 2, and the collar 2c on the drain hose 2 side and the holding portion 3a on the hose fixing tool 3 side. By combining them, the drain hose 2 can be prevented from coming off from the drain port 1c. FIG. 2 is a cross-sectional view showing the connection state of the drain pan 1, the drain hose 2, and the hose fixing tool 3. The drain pipe 1c of the drain pan 1 is connected to the end pipe portion 2b of the drain hose 2, and the hose fixing tool 3 is attached thereto. When the drain hose 2 is covered, the collar 2c on the drain hose 2 side is clamped by the clamping portion 3a on the hose fixing tool 3 side, and the periphery and the surface of the water collecting section 1b are surrounded by the hose fixing tool 3.

[0008]

[Effect of device]

 In the case of the drainage device configured as described above, by connecting the drain hose to a predetermined position of the drain pan and fixing the hose fixing tool to the drain pan side, the collar provided on the drain hose is fixed to the hose. Since it is clamped by the clamp part of the tool, there is no accident that the drain hose will come off the drain pan and cause water leakage, and there is no risk of dew condensation around the drain outlet where the hose fixing tool is covered. Easy to assemble without needing to apply heat material
