Abstract

(57) [Abstract] [Purpose] To obtain an air conditioner with good serviceability that can secure a service space without removing the mounting screws during maintenance and inspection services of the compressor. [Structure] One end of the drain pan 6 is rotatably supported by a support column 8 provided upright on the peripheral edge of the underframe 7, and the other end is opposed to the other end.
It is adapted to be engaged with the drain pan receiver 13 provided on the.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an air conditioner equipped with a drain pan below a heat exchanger.

[0002]

[Prior Art]

 FIG. 4 is a sectional view of an air conditioner disclosed in, for example, Japanese Patent Application No. 2-10709, and FIG. 5 is a sectional view showing details of a drain pan mounting structure of FIG. In these drawings, 1 is a machine room, 2 and 3 are compressors and liquid separators fixed to the underframe 7 and arranged in the machine room 1, and 4 and 5 are at four corners of the underframe 7. Blower supported by four fixed columns 8 and heat exchanger on the utilization side, 6 is a drain pan fixed to the screw holes 10 of the columns 8 with screws 11, 9 is a side plate, and screws are attached to the holes of the columns 8. It is fixed by 12.

In the air conditioner configured as described above, for example, when replacing the compressor 2 or servicing a refrigerant circuit component, a space required for servicing is provided between the compressor 2 and the drain pan 6. If not, remove the screw 11 fixing the drain pan 6 to the column 8 and lift the drain pan 6 upward or remove it.

[0004]

[Problems to be solved by the device]

 Since the conventional air conditioner is configured as described above, if you want to remove the drain pan or move it upward during service, it is necessary to remove the screw fixing the drain pan. To prevent it from happening, the screw must be removed while supporting the drain pan, so it is impossible for one person to do the work, so the serviceability is very poor and the work time is wasted.

The present invention has been made to solve the above-mentioned problems, and the drain pan can be rotated without removing the mounting screw, and the service space can be obtained by the rotation. The purpose is to obtain a good air conditioner.

[0006]

[Means for Solving the Problems]

 In the air conditioner according to the present invention, one end of a drain pan is pivotally attached to a pillar standing on a peripheral portion of an underframe, and the other end is opposed to the other pillar or the drain pan provided on the pillar. It is adapted to engage with the receiver.

[0007]

[Action]

 In the air conditioner according to the present invention, when the side of the drain pan that engages with the pillar or the side of the drain pan that engages with the drain pan receiver is lifted, the drain pan rotates about the pivot point of the pillar and the service space is obtained.

[0008]

【Example】

 Example 1. An air conditioner according to an embodiment of the present invention shown in FIGS. 1 and 2 will be described below. FIG. 1 is a sectional view showing the main part thereof, and FIG. 2 is a sectional view taken along the line II-II of FIG. In FIGS. 1 and 2, the difference from FIGS. 4 and 5 is that one end of the drain pan 6 is provided with four screws 8 for the rear surface from the inside of the drain pan 6 by using screws 11 for the rear surface, that is, of the air conditioner. A force to attach the other end of the drain pan 6 to the two front columns 8 facing the other end by the weight of the drain pan 6 and to rotate the screw 11 about its axis. It is the point that is fixed by pressure. Next, the operation will be described. For example, when replacing the compressor 2, if the engaging side of the drain pan 6 with the column 8 is lifted, the drain pan 6 rotates counterclockwise about the screw 11 as shown by the chain line, and the drain pan 6 is rotated. A service space is secured between the compressor and the compressor 2. Then, the replacement work of the compressor 2 is performed.

Example 2. FIG. 3 is a sectional view showing another embodiment of the present invention. Unlike FIG. 1 and FIG. 2, the other end of the drain pan 6 whose one end is rotatably attached to the column 8 with a screw 11 is attached to the column 8. The point is that the drain pan receiver 13 provided at the above is pressed and fixed by the force of the drain pan 6 which is rotated by its own weight. Since the function and effect are similar to those of the above-mentioned embodiment, the description thereof will be omitted.

[0010]

[Effect of the device]

 As described above, according to the present invention, one end portion of the drain pan is rotatably supported by the support pillar standing on the peripheral portion of the underframe, and the other end is opposed to the other end or the above support pillar. Since it is configured to engage with the drain pan receiver provided on the column, the drain pan is rotated to secure the service space by lifting the engaging portion of the drain pan at the time of servicing, and maintenance and inspection of the compressor etc. is performed. As a result, the work time is greatly shortened, and the serviceability is improved.
