Abstract

PURPOSE:To facilitate collection of an operation wire and a piping, to improve appearance, and to prevent lengthening of the operation wire by a method wherein a cover with which a service port formed in the one side of a heat exchange unit and connection tools are covered in one lot is provided, and a guide part for a piping is mounted to the cover. CONSTITUTION:Terminal boards (electrical equipment) 5 and 6 are arranged to the vicinity of the opening of a service port 4, and a cover 11 with which the service port 4 and connection tools 7 and 8 are covered in one lot has a front part 12 formed in a plateform manner and a rear part (guide part) 13 formed approximately in a U-shape in cross section. The cover 11 is brought into contact with a jacket body such that the service port 4 is covered with a front part 12 and the connection tools 7 and 8 are coved with a rear part 13. The cover 11 is secured to a jacket body 3 by means of a screw in a state that a mounting hole 15 of the cover 11 is caused to coincide with a screw hole 14 of the jacket body 3. An operation wire 19 connected to an indoor unit 16 is extended from a terminal plate 5 located to the upper part of the interior of the service port 4, and a source feeder 20 is extended from a terminal plate 6 situated to the lower part of the interior of the service port 4. Hot water tubes 18 and 22 and the operation wire 19 are run downward along the cylindrical part of the rear part 13 of the cover 11 and the right side of the jacket body 3.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a heat exchange unit such as an outdoor unit of a separate air conditioner.

(b) Conventional technology In general, outdoor units of separate air conditioners have
As shown in Japanese Patent No. 8-46374, a service port for electrical components and a connector to which piping from the indoor unit is connected are provided on one side of the exterior body. When installing this separate air conditioner, insert the operating wire from the indoor unit through the service port, connect this operating wire to the electrical components inside the service port, close the service port with a cover, and cover the operating wire with the exterior. It is fixed by pressing it against the body.

On the other hand, piping from the indoor unit is connected to the connector.

(c) Problems to be Solved by the Invention As described above, since the operating line and the pipe connected to the connector extend separately from one side of the outdoor unit, the appearance is poor. Furthermore, unless the operating wire and piping are integrated together near one side of the outdoor unit, the operating wire may be unnecessarily exposed from the outdoor unit and become tangled in the connector.

The present invention makes it easier to organize the operating lines and piping drawn out from one side of the outdoor unit for a better appearance, and
The purpose is to prevent this operating line from becoming unnecessarily long.

(2) Means for Solving the Problems In order to achieve this object, the present invention includes a cover that brings together the service port and the connector provided on one side of the outdoor unit, and the cover has the connector. It forms a guide part for the pipes connected to each other.

(E) When the operation cover is attached to one side of the outdoor unit's exterior body, the operating wire pulled out from the service port and the piping connected to the connector are guided by the guide part of this cover and are routed from the same place to the outside of the outdoor unit. be led to.

(f) Embodiment In Figures 1 and 2, the construction is an outdoor heat exchange unit (hereinafter referred to as "outdoor unit") of a separate air conditioner.
Inside, the condenser and compressor are housed in the lower part, and the hot water boiler is housed in the upper part. 2 is a service valve provided on the right side of the exterior body 3 of this outdoor unit 1;
It is connected to the condenser and compressor with refrigerant piping. 4 is a service opening, and terminal boards (electrical components) 5 and 6 are arranged near the opening. 7 and 8 are connectors, which are connected to the hot water boiler through hot water pipes. A pair of these connectors are arranged in the front and back direction. Also, these connectors 7 and 8 have downward connection ports 9.
, 10 are formed. 11 is this service port 4
and connectors 7 and 8 together.
is formed into a flat plate shape, and the rear portion (guide portion) 13 is formed into a substantially U-shaped cross section. This cover 1 is placed so that the front part 12 covers the service port 4 and the rear part 13 covers the connectors 7 and 8, respectively.
1 to the exterior body 3, the mounting holes 15 of the cover 11 are aligned with the screw holes 14 of the exterior body 3, and the cover 11 is fixed to the exterior body 3 with screws.

31m and 4 show the installation state of this outdoor unit 1, and 16 is an indoor unit of a separate air conditioner, which includes a heat exchanger (evaporator) into which refrigerant flows during cooling and a heat exchanger into which hot water flows during heating. (heat sink) is built-in. 17
is connected to the evaporator by a refrigerant pipe connected to service valve 2. Reference numeral 18 is a hot water pipe connected to a connection port 9 of one of the connectors 7 and 8, and is connected to a radiator.

Reference numeral 19 denotes an operating line connected to the indoor unit 16, which extends from the terminal plate 5 above the service port 4. Reference numeral 20 denotes a power supply line extending from the lower terminal board 6 within the service port 4. The refrigerant pipe 17, one hot water pipe 18, the operating line 19, and the power supply line 20 are integrally wrapped with decorative tape 21. 22 is the other hot water pipe, connecting fitting 7,
8 is connected to the other connector 10. This other hot water pipe 22ζ, the hot water outlet 24 fixed to the wall 23
is connected to. 25 is a hot water mat spread on the floor.
A plug 27 of a hot water pipe 26 of this mat is connected to a hot water outlet 24. 28 is an overcarpet laid on the hot water mat 25.

Here, one and the other hot water pipe 18.22 and operation line 1
9 extends down the right side of the exterior body 3 along the cylindrical portion of the rear part 13 of the cover 11. In particular, the operating wire 19 is led backward from the service port 4 (towards the wall 23 in FIG. 4), and then pulled out from the bottom of the cover 11 along one hot water pipe 18. After being pulled out from the cover 11, it always extends integrally with one of the hot water pipes 18.

Note that during cooling operation, the compressor in the outdoor unit 1 is operated to send refrigerant to the evaporator of the indoor unit 16, while during heating operation, the boiler in this outdoor unit 1 is operated to send hot water to the radiator of the indoor unit 16. and hot water mat 25 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 using only the indoor unit 16.

In FIG. 3, various hot water pipes 18, 22, refrigerant pipes 17, etc. are shown bent as necessary to make them easier to understand. Note that in a normal outdoor unit in which only a compressor and a condenser are housed (a hot water boiler is not housed), the service valve 2 and the service port 4 may be covered with a cover 11.

(G) Effects of the Invention As described above, the present invention is provided with a cover that gathers together the service port and the connector provided on one side of the heat exchange unit, and a piping guide portion is provided on this cover. Therefore, the operating wire pulled out from the service port and the piping connected to the connector are led to the outside of the heat exchange unit from the same place on this cover, making it possible to improve the appearance of one side of the unit. The operating wire can be routed along the piping from within the cover, reducing the possibility that the operating wire will unnecessarily come out of the heat exchange unit.
