Description

[Detailed Description of the Invention] This invention relates to a ceiling-suspended air conditioner, and particularly relates to an improvement of a drain processing device for a refrigerant pipe connection located within the main body.

Conventionally, this type of ceiling-mounted air conditioner has been constructed as shown in FIG. 1, in which numeral 1 is an air conditioner main body, and a drain pan 2 is disposed at the bottom of the front side. Reference numeral 3 denotes a refrigerant pipe connection part that connects refrigerant pipes between a plurality of main body side pipes 31 and external equipment side pipes 32, and is located in the pipe connection space 12 partitioned by the drain pan 2 and the partition 11 on one side of the main body 1. are doing. Reference numeral 5 denotes a heat insulating material a that tightly wraps each of the refrigerant pipe connection parts 3.

In addition, as a conventional example disclosed in Utility Model Application Publication No. 55-5031, as shown in FIG.
A gutter-shaped auxiliary drain pan 4 made of a thermally poor conductor is provided below the header 15 of the evaporator 13 on the side of the tube plate 14 that supports the evaporator. 13 and side plate 16
It is a structure that is sandwiched between.

In the former case, the space for connecting the pipes on one side of the main body is very narrow, so during the connection work at the main body installation site, it is necessary to remove the insulation material at the joint after the pipes are connected. This has resulted in drawbacks such as the winding work being difficult, troublesome, and lacking in safety.

In addition, in the latter case, the condensate from multiple piping adjacent to the evaporator is assembled at the same time when assembling the main body, so it has the disadvantage that it cannot be applied to condensate from the piping connection. Ta.

The purpose of the present invention is to easily and reliably drain the drain from the joint after piping is connected, where the piping connection space is extremely narrow, and to perform the installation work quickly and safely.

This invention will be explained below with reference to embodiments shown in FIGS. 2 and 3.

1 is an air conditioner main body, and a drain pan 2 is disposed at the bottom of the front side. Reference numeral 3 denotes a refrigerant pipe connection part that connects refrigerant pipes between a plurality of main body side pipes 31 and external equipment side pipes 32, and is located in the pipe connection space 12 partitioned by the drain pan 2 and the partition 11 on one side of the main body 1. are doing. Reference numeral 4 denotes a drain receiver, which is composed of a receiver 41 and a discharge port 6, and the receiver 41 forms a discharge passage 61 in the center that slopes toward the discharge port 6, and further slopes from both sides toward the discharge port 61. An integrally molded dish portion 7 is provided. Reference numeral 42 denotes a boss that is inserted into the partition 11 and removably attached when the drain receiver is positioned in the piping connection space 12 of the main body 1, and is attached to the receiving portions 4 on both sides of the discharge port 6.
It is formed protrudingly on the contact surface 44 of 1. Reference numeral 8 denotes a heat insulating material b, which is attached to the outer surface of the drain receiver 4.

Next, assembling will be described. First, after the main body 1 is installed on the ceiling, the main body side piping 31 and the external equipment side piping 32 are connected from below or from the side within the piping connection space 12 of the main body 1. Next, the receiving part 41 of the drain receiving part 4 is positioned so as to correspond to the lower position of the connecting part 3 from below or from the side. The boss 42 may be inserted and fixed so that the contact surface 44 of the portion 41 is brought into contact with the partition 11.

As mentioned above, this device has a structure in which a piping connection space is provided on one side of the main body to connect the refrigerant piping with a drain pan and a partition, and the piping on the main body side and the piping on the external equipment side are provided in the piping connection space. At the same time, a receiver is provided below the refrigerant pipe connection, and a drain receiver is provided with the discharge port passing through the partition and looking onto the drain pan, and this drain receiver is installed in the pipe connection space. After the refrigerant piping work is completed, the installation can be inserted and removed from below or from the side, making it extremely easy and safe to connect the pipes within the piping connection space of the main unit. The installation work of the drain receiver can be simplified, the work time can be shortened, and safety can be ensured extremely easily.
This has the effect of eliminating heat insulation at the refrigerant pipe connection portion and allowing smooth dew treatment at the refrigerant pipe connection portion.
