Abstract

PURPOSE:To facilitate joint work by laying out a liquid side three way valve and a gas side three way valve for piping connection so that their respective connection port central line may be inclined with an angle and having an intersection of the connection port central line on an extended line a piping connection port side. CONSTITUTION:A liquid side three way valve 2 connected with a refrigerant circuit of a compressor or the like and a gas side three way valve 3 are also inclined against the outside of an indoor air conditioner 1 so that their respective connection port central lines A and B may be arrayed with an angle and the intersection of their connection port central lines A and B are arranged to be positioned on an extended line O of a piping connection port side. Under this construction, both three way valves are mounted to the outside of the main body 1. Therefore, this construction allows both connection pipeline 4 and 5 to be connected with the liquid side three way valve 2 of the outdoor equipment main body 1 and the gas side three way valve 3 at the nearest position on one end, and moreover both pipelines are bare. More specifically, the connection port central lines A and B are positioned in the nearest distant from the intersection O of the piping connection side on the extended line respectively, which makes it possible to facilitate joint work and eliminate any need to extend the bare piping section as well.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a connection between a liquid-side three-way valve and a gas-side three-way valve for piping connection of an outdoor unit in a separate air conditioner.

Conventional technology Conventionally, a separate air conditioner is composed of an outdoor unit and an indoor unit, and the three-way valve on the liquid side and the three-way valve on the gas side for connecting the pipes of the outdoor unit are connected as shown in Figure 2. . That is, a refrigerant circuit such as a compressor (not shown), an electrical component, etc. are provided inside the outdoor unit main body 11, and a liquid side three-way valve 12 and a gas side three-way valve 13 connected to the refrigerant circuit such as the compressor are installed. The outdoor unit main body 1
The connectors are arranged and attached to the outer surface of the connector 1 so that the center lines C and D of the respective connection ports are parallel to each other. In this way, the connecting pipes 14 and 15 to the liquid side three-way valve 12 and gas side three-way valve 13 of the outdoor unit main body 11 are covered with a resin covering material 16, and each connecting pipe 14 and 15 is made into a bare pipe state, One end is connected, and the other end is connected to an indoor unit (not shown) by a construction contractor to complete the construction work.

As a result, the refrigerant circuit such as the compressor is connected to the indoor unit.

Problems to be Solved by the Invention In such a conventional configuration, the contractor installed the connecting pipe 14 in the form of a bare pipe between the liquid side three-way valve 12 and the gas side three-way valve 13.
．． When connecting 15, since it is connected along the center of the connection port 1c and D, the bare pipe section will inevitably be long, and for this reason, the distance to the part where taping or pipe cover can be applied as a finishing touch to the pipe is long. There were problems such as the edges were unsightly and the connection was difficult.

The present invention solves these problems, and in order to make the construction work easier and to improve the finish after the construction work, taping or piping covers are installed between the three-way valve on the source side and the three-way gas side valve. It is an object of the present invention to provide a connection device for an outdoor unit of a separate air conditioner that can be connected with a short bare pipe.

Means for Solving the Problem In order to solve this problem, the present invention provides a method in which the center lines of the connection ports of the source-side three-way valve and the gas-side three-way valve for connecting pipes provided on the outer surface of the main body are arranged at an angle. The intersection point of the center line of the connection port is located on the extension wire on the side of the pipe connection port.

Effect: With this configuration, one end of the connection pipe, which is in a bare pipe state, is connected to the source side three-way valve and the gas side three-way valve, which are arranged so that the intersection of the connection port center lines is on the extension line of the pipe connection port side. ,
Once this connection is complete, taping or piping) Y-bars are applied leaving a short bare tube section.

EXAMPLE An example of the present invention will be described below with reference to FIG. A refrigerant circuit such as a compressor (not shown), an electrical component (not shown), etc. are installed inside the outdoor unit main body, and the direction in which the source-side three-way valve 2 connected to the refrigerant circuit such as the compressor is inclined is The connection port center lines A and B are arranged at an angle on the outer surface of the outdoor unit main body 1 so that the connection port center lines A and B are arranged at an angle so that the three-way valve 3 and the gas side three-way valve 3 form a substantially C shape. The pipes are arranged and designed so that the intersection point is on the extension line O of the pipe connection port (1111).

In this configuration, one ends of the connecting pipes 4 and 5 can be connected to the source side three-way valve 2 and gas side three-way valve 3 of the outdoor unit main body 1 at positions immediately adjacent to each other and in the form of bare pipes. In other words, since the connection port center lines A and B are close to each other and the intersection point ○ of the extension line on the piping connection port side, connection construction is very easy, and there is no need to lengthen the bare pipe section for each. There is none. In this way, the source side three-way valve 2 and the gas side three-way valve 3 are connected, and the contractor connects the other end to the indoor unit (not shown) to complete the construction work.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a method in which the center lines of the connection ports of the source-side three-way valve and the gas-side three-way valve for piping connection provided on the outer surface of the main body are arranged at an angle. Since the intersection of the center line of the connection port is located on the extension line of the pipe connection port side, connection construction is very easy, and when connecting the connection pipes to the source side three-way valve and gas side three-way valve, the finishing of the piping is very easy. When applying taping or piping cover as a pipe, the distance of the bare pipe to the part where taping or piping cover is applied is extremely short without bending the connecting pipe, which has the effect of making the finished product beautiful. It is something. still,
In this example, the explanation is given for a case where the source side three-way valve and the gas side three-way valve are a pair like in a general room air conditioner. In some cases, it can be even more effective.
