Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an indoor unit of an air conditioner, and more specifically, to make it easy and reliable to connect a drain hose (drain hose) connected to a drain port of a drain pan that receives condensed water of a heat exchanger. Regarding the means of.

[0002]

[Prior Art]

 In the indoor unit of the air conditioner, for example, as shown in FIG. 5, a drain pan 12 for receiving condensed water flowing down from the heat exchanger 11 is provided below the heat exchanger 11. A drain port 13 is provided below the drain pan 12, and a drain hose 14 for guiding the condensed water collected in the drain pan 12 to the outside of the room is connected to the drain port 13. The drain hose 14 is composed of a hose body 14a and a heat insulating material 14b covering the outer periphery of the hose body 14 for preventing ice formation. In connection with the drain port 13, first, the hose body 14a is covered with the drain port 13. Then, the hose body 14a was fastened with a band 15 around the outer periphery of the heat insulating material 14b so that the hose body 14a would not come off from the drainage port 13.

[0003]

[Problems to be solved by the device]

 However, in the combination of the drainage port 13 and the drain hose 14 as described above, in order to prevent water from leaking from the fitting portion, both are designed with the barely necessary dimensions for fitting. Therefore, the drain hose 14 is not easily attached to the hose body, and if the attachment is not enough, the drain hose 14 is easily pulled out. The band 15 is not directly fastened to the hose body 14a, but indirectly fastened from the outer periphery of the heat insulating material 14b. However, it was not sufficient as a measure to prevent the drain hose 14 from coming off. Therefore, in the present invention, these problems are solved and the drain pan 12 and the drain hose 14 can be connected more easily and securely, and an indoor unit of an air conditioner that does not cause problems such as water leakage can be provided. It is intended to be provided.

[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 located under the heat exchanger and combines it with the drain port of the drain pan. In an indoor unit of an air conditioner that discharges to the outside via a drain hose that is installed, a water receiving container that receives the condensed water that flows down from the drain port of the drain pan is provided on one side of the drain hose. A mounting portion for the water receiving container is provided below the drain port, and a locking portion for preventing the water receiving container from falling is provided on either or both of the mounting portion and the water receiving container.

[0005]

[Action]

 With the above configuration, a water receiving container for receiving condensed water from the drain pan is provided at the tip of the drain hose, while a mounting part for the water receiving container is provided under the drain port of the drain pan. Therefore, the drain pan and drain hose can be connected simply by mounting the water receiving container to this mounting part, and further, the mounting part and / or the water receiving container can be connected to the mounting part. Since the locking part is provided to prevent the attached water receiving container from falling off, the water receiving container is prevented from falling off and water leakage from the drain port can be eliminated.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a drain pan used in an indoor unit of an air conditioner and a main part on a drain hose side that is connected to the drain pan, and FIG. 2 is a side cross-sectional view showing the connected parts. In the figure, 1 is a drain pan, 2 is a drain hose, 3 is a water receiving container provided on one side of the drain hose 2, 4 is a mounting portion of a water receiving container 3 provided under the drain pan 1, and 5 is a drain pan 1 The drainage port 6 is a locking part integrally formed on the lower portion of the drain pan 1 to prevent the water receiving container 3 mounted on the mounting part 4 from falling off.

The drain pan 1 is a plastic container provided to receive the dew condensation water flowing down from a heat exchanger (not shown) and to flow it to the drain hose 2 side. As shown in FIG. The drain port 5 is provided in the lower part, and a mounting part 4 for mounting the water receiving container 3 is formed in the lower part of the drain port 5. The mounting portion 4 is composed of a bottom surface of the drain pan 1 and a support piece 7 formed in a substantially L shape in the lower part thereof, and a central portion of the bottom surface of the support piece 7 is opened for forming a drainage port 5. Further, locking portions 7a and 7b are provided on the upper end of the support piece 7 to prevent the water receiving container 3 from falling off when the water receiving container 3 is mounted on the mounting portion 4.

On the other hand, the water receiving container 3 receives the condensed water flowing down from the drain port 5 and flows to the drain hose 2 side, so the upper part is opened and a part of the bottom surface has good water flow. It is formed obliquely so that it can be bent and easily mounted on the mounting portion 4, and the outlet 3a side is cylindrical for fitting with the drain hose 2. The drain hose 2 is composed of an inner hose body 2a and an outer heat insulating material 2b, and the fitting surface between the outlet 3a side of the water receiving container 3 and the hose body 2a is fixed by an adhesive. Since the water receiving container 3 and the hose 2 are integrated as described above, the water receiving container 3 can be easily mounted on the mounting portion 4, and the water receiving container 3 once mounted is locked by the locking portions 6, 7a, 7b. Therefore, the position of the water receiving container does not shift or fall off, and there is no possibility of water leakage.

FIG. 3 and FIG. 4 are for explaining another embodiment. The difference from the former is that the locking portions 6, 7a, 7b provided on the drain pan 1 side are eliminated and replaced with these. The locking portions 3b and 3c are provided behind the water receiving container 3. With such a structure, the water receiving container 3 can be more easily attached to the attaching portion 4, and once attached, the movement of the locking portions (3b, 3c) is less than that in the former case, and accordingly, the support is required. The power is getting stronger. In the former case, the locking portion is provided on the drain pan 1 side, and in the latter case, the locking portion is provided on the water receiving container 3 side. However, the locking portion is not limited to this, and is provided on both the drain pan 1 and the water receiving container 3. Also, the position and shape may be different.

[0010]

[Effect of the device]

 In the case of the air conditioner having the drain pan and the drain hose as described above, the drain pan and the drain hose can be easily installed simply by mounting the drain hose side water receiving container on the mounting part provided on the drain pan. It can be connected, and the water receiving container mounted on the mounting part is locked by the locking part and cannot be easily returned, so the water receiving container does not come off and there is no risk of water leakage.
