Description

The present invention relates to a heat exchange unit such as an outdoor unit of a separation type air conditioner.

(B) Conventional technology In general, the outdoor unit of a separation type air conditioner has
As shown in Japanese Patent Laid-Open No. 8-46374, a service port for electrical equipment and a connector to which piping from an indoor unit is connected are provided on one side surface of the exterior body. Then, when installing this separation type air conditioner, insert the operation line from the indoor unit from the service port, connect this operation line to the electric parts in the service port, and close the service port with a cover to cover the operation line. It is fixed while pressing it against the body.
On the other hand, a pipe from the indoor unit is connected to the connector.

(C) Problem to be Solved by the Invention As described above, since the operation line and the pipe connected to the connector are separately extended from one side surface of the outdoor unit, the appearance is not good. Further, unless the operation line and the pipe are integrated together at a location near one side surface of the outdoor unit, the operation line may be unnecessarily exposed from the outdoor unit and caught in the connector.

The present invention makes it easy to put together the operation line and the piping drawn out from one side surface of the outdoor unit and improves the appearance,
The purpose is to prevent the operating line from becoming unnecessarily long.

(D) Means for Solving the Problem In order to achieve this object, the present invention is provided with a cover that collectively covers a service port and a connector provided on one side surface of an outdoor unit, and the cover has a connector. The guide part of the connected pipe is formed.

(E) Action When the cover is attached to one side of the exterior of the outdoor unit, the operation line drawn out from the service port and the pipe connected to the connection tool are guided by the guide part of this cover, and the outside of the outdoor unit from the same location. Be guided to.

(F) Embodiment In FIGS. 1 and 2, 1 is a heat exchange unit on the outdoor side of the separation type air conditioner (hereinafter referred to as “outdoor unit”).
A condenser and a compressor are stored in the lower part of the inside, and a hot water boiler is stored in the upper part. 2 is a service valve provided on the right side surface of the exterior body 3 of the outdoor unit 1,
It is connected to the condenser and compressor by refrigerant piping. A service port 4 is provided with terminal boards (electrical components) 5 and 6 near the opening. Reference numerals 7 and 8 are connecting tools, which are connected to a hot water boiler by a hot water pipe. A pair of these connectors is arranged in the front-rear direction. Further, the connection tools 7, 8 are formed with two downward connection ports 9, 10. Reference numeral 11 is a cover that collectively covers the service port 4 and the connecting tools 7 and 8, and is a front portion 1.
2 has a flat plate shape, and a rear portion (guide portion) 13 has a substantially U-shaped cross section. Then, the cover 11 is applied to the exterior body 3 so that the front part 12 covers the service port 4 and the rear part 13 covers the connection tools 7 and 8, respectively, and the mounting hole 15 of the cover 11 is aligned with the screw hole 14 of the exterior body 3. Then, the cover 11 is fixed to the exterior body 3 with a screw.

3 and 4 show the installed state of the outdoor unit 1, and 16 is an indoor unit of a separation type air conditioner, which is a heat exchanger (evaporator) into which a refrigerant flows during cooling and a heat exchanger into which hot water flows during heating. The container (radiator) is built in. 17
Is connected to the evaporator by a refrigerant pipe connected to the service valve 2. Reference numeral 18 is one hot water pipe connected to one of the connection ports 9 of the connection tools 7 and 8 and connected to the radiator. 19
Is an operation line connected to the indoor unit 16 and extends from the upper terminal plate 5 in the service port 4. A power supply line 20 extends from the lower terminal plate 6 in the service port 4. The refrigerant pipe 17, the hot water pipe 18 on one side, the operation wire 19 and the power supply wire 20 are integrally wound with a decorative tape 21. 22 is the other hot water pipe, which is the connection tool 7,8.
Is connected to the other connection tool 10. The other hot water pipe 22 is connected to a hot water outlet 24 fixed to a wall 23. 25 is a hot water mat laid on the floor, and the plug 27 of the hot water pipe 26 of this mat is the hot water outlet 24.
Connected to. 28 is an over carpet laid on the hot water mat 25.

Here, the one and the other hot water pipes 18, 22 and the operating wire 1
9 extends down the right side surface of the exterior body 3 along the tubular portion of the rear portion 13 of the cover 11. In particular, the operation line 19 is guided rearward from the service port 4 (toward the wall 23 side in FIG. 4) and then pulled out from the lower part of the cover 11 along one of the hot water pipes 18. After being pulled out from the cover 11, it is always extended integrally with one hot water pipe 18.

In the cooling operation, the compressor in the outdoor unit 1 is operated to send the refrigerant to the evaporator of the indoor unit 16, while in the cooling operation, the boiler in the outdoor unit 1 is operated to supply hot water to the radiator of the indoor unit 16. And the warm water mat 25 are sent at the same time. Alternatively, the plug 27 of the hot water pipe 26 of the hot water mat 25 may be removed from the hot water outlet 24 to heat the room only by the indoor unit 16. In FIG. 3, the various hot water pipes 18, 22 and the refrigerant pipe 17 are shown bent as necessary so that they can be easily understood. In addition, in a normal outdoor unit in which only the compressor and the condenser are stored (the hot water boiler is not stored),
The service valve 2 and the service port 4 may be covered with the cover 11.

(G) Effect of the Invention As described above, the present invention is provided with the cover that collectively covers the service port and the connection tool provided on one side of the heat exchange unit, and the guide part of the pipe is provided in this cover. Therefore, the operation line drawn out from the service port and the pipe connected to the connector are guided to the outside of the heat exchange unit from the same place of this cover, and the appearance of one side of this unit can be improved. Moreover, the operation line can be provided along the pipe from inside the cover, and the possibility that the operation line is unnecessarily exposed to the outside of the heat exchange unit can be reduced.
