BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an outdoor unit in a separate air conditioner.

0002

2. Description of the Related Art Separate air conditioners are separated into an indoor unit and an outdoor unit. The indoor unit houses an indoor heat exchanger, an indoor blower, and the like, and the outdoor unit houses an outdoor heat exchanger, a compressor, an outdoor blower, and an electrical parts box containing electrical parts for controlling these. The indoor unit and the outdoor unit are connected by piping, and the refrigerant compressed by the compressor is circulated through the piping.

A conventional outdoor unit was constructed as shown in FIGS. 5 and 6. That is, 1 in the figure is the main body of the outdoor unit. This main body 1 is formed into a hollow rectangular parallelepiped shape. As shown in FIG. 5, a box-shaped electrical component box 2 with a first tongue piece 2a extending from the lower end of the main body 1 is installed in the upper part of the interior of the main body 1 on one end side. This electrical parts box 2
Electrical components (not shown) housed therein are connected to a control section provided in the indoor unit by an electrical cable (not shown).

An upper opening 3 is formed in a portion of the main body 1 that corresponds to the electrical component box 2. A second tongue piece 3 a extends upwardly into the interior of the main body 1 from the lower end of the upper opening 3 . The first tongue piece 2a is joined to the second tongue piece 3a, and these are fixed with screws 4. The upper opening 3 is closed with a wiring cover 6 fixed to the outer surface of one side of the main body 1 with a screw 5. At the lower end of this wiring cover 6 is an electrical cable lead-out portion 6.
a is formed.

In FIG. 5, reference numeral 7 denotes a space inside the main body 1 in which an outdoor heat exchanger and an outdoor blower (both not shown) are installed, and a space in which a compressor (not shown) is installed. It is a partition plate that separates the

[0006] A lower opening 8 is formed in the lower part of one side of the main body 1 . This lower opening 8 is closed by a mounting plate 9. A pair of packed valves 11 are attached and fixed to this mounting plate 9. That is, the pair of packed valves 11 are provided so as to protrude from the main body 1. One end of refrigerant piping (not shown) is connected to these packed valves 11 . The other end of this pipe is connected to an indoor unit (not shown). That is, the outdoor unit and the indoor unit are connected by the piping.

The packed valve 11 is exposed to the outside. Furthermore, although the piping is covered with a heat insulating material, the connection end connected to the packed valve 11 is exposed to the outside because it is difficult to cover it with a heat insulating material. Therefore, these exposed parts are covered with a cover 12 made of a heat insulating material such as expanded polystyrene to prevent condensation and heat loss.

An electric cable (not shown) led out from the lead-out portion 6a of the wiring cover 6 and the packed valve 1
The pipes connected to 1 are held and fixed by a pipe holder 13 that is integrally joined with decorative tape (not shown) and attached to the side of the upper opening 3. electric cable
Since the lead-out position of the pipe is different from that of the piping, a part of it is not covered with decorative tape and is exposed to the rain.

In the outdoor unit thus constructed, the packed valve 11 is provided to protrude from the outer surface of the main body 1, so the cover 12 covering the packed valve 11 protrudes even further. Therefore, the protruding cover 12 not only greatly reduces the appearance of the outdoor unit, but also may become a nuisance. In addition, the packed valve 11 and the end portions of the pipes exposed to the outside must be covered with the cover 12. In other words,
Since the packed valve 11 must be covered with a cover 12 which is a separate part from the wiring lid 6 that covers the upper opening 3, the number of parts increases, leading to increased costs and complicated assembly work.

[Problems to be Solved by the Invention] As described above, in conventional outdoor units, the packed valves protrude significantly from the outside of the main body, which makes them look unsightly, and the packed valves exposed to the outside must be covered with special covers. This has led to an increase in the number of parts and complicated assembly work.

The present invention was made based on the above circumstances, and its purpose is to improve the appearance and reduce the number of parts by providing the valve without protruding to the outside of the main body. Our goal is to provide outdoor units for air conditioners.

0012

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a main body of an outdoor unit, an opening formed in one side wall of the main body, and a position facing the opening in the upper part of the main body. an electrical parts box disposed in the main body, a support member provided at a position facing the opening on the inner bottom of the main body, a valve for connecting piping held on the support member, and a valve for closing the opening and The present invention is characterized by comprising a cover formed with an insertion portion through which the piping is passed.

[0013]

[Operation] According to the above structure, the valve is provided inside the main body and does not protrude or be exposed to the outside.
Not only does it look good in appearance, but it also eliminates the need for a special cover to prevent condensation and heat loss at the bulb.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In the figure, 21 is the main body of the outdoor unit. An electrical component box 22 in which electrical components are housed is disposed in the upper part of one end of the main body 21 . A dogleg-shaped tongue piece 23 extends downward from the lower end of one side of the electrical component box 22.

An L-shaped support member 25 is erected on the upper surface of one end side of the bottom plate 24 of the main body 21. A pair of packed valves 26, which are valves to which one end of a refrigerant pipe is connected, are attached and fixed to this support member 25. That is, the support member 25 is erected at a position where the packed valves 26 do not protrude outside the main body 21 when the packed valves 26 are attached.

On the side wall 21a at one end of the main body 21,
Part of the electrical parts box 22 and the packed valve 2
An opening 27 having a size corresponding to 6 is formed. This opening 27 is closed by a cover 28 made of synthetic resin or the like. This cover 28 is formed into a thin box shape with a peripheral wall 28a, and its upper end is screwed into the tongue piece 23 of the electrical component box 22, and its lower end is screwed into an upright piece 24a bent at the end of the bottom plate 24. 29. Further, the above-mentioned side wall 2 is provided on the inner surface of the upper part of the cover 28.
An engaging piece 28b that engages with the edge of the opening 27 of 1a is provided.

The peripheral wall 28a of the cover 28 has a plurality of blind portions 3 connected by thin wall portions 32, as shown in FIG.
3 is formed. This blind portion 33 can be removed by cutting the thin portion 32 with a knife or the like.

As shown in FIG. 3, the portion of the peripheral wall 28a from which the blind portion 33 has been removed is an electrical cable that electrically connects the electrical components housed in the electrical component box 22 to the control section of the indoor unit (not shown). 34 and the packed valve 26
This serves as an insertion portion 36 through which a refrigerant pipe 35 whose one end is connected is passed. The pipe 35 is covered with a heat insulating material (not shown). In this embodiment, as shown in FIG. 3, an insertion part 36 is formed on one side of the cover 28, and the electric cable 34 and piping 35 are integrally connected through the insertion part 36 with a decorative tape 37. It is derived in the state. In other words, the electric cable 34 and piping 35 are
Since the leading positions from the cover 28 can be made the same, the decorative tape 37 can be used to integrate the parts and lead them out to the outside. As a result, not only the piping 35 is not directly exposed to the outside, but also the electric cable 34 has no portion exposed to the outside in a rainy state.

According to the outdoor unit constructed in this manner, the pair of packed valves 26 are provided inside the main body 21 in such a manner that they do not protrude to the outside from the opening 27 formed in the side wall 21a. Therefore, the opening 2
Since the cover 28 that closes the cover 7 does not need to protrude significantly from the outside of the side wall 21a of the main body 21, it is possible to not only improve the appearance of the outdoor unit, but also to avoid getting in the way and making it easier to install the outdoor unit. You can also make the space smaller.

[0020] By closing the opening 27 with the cover 28, the ends of the pair of packed valves 26 and the piping 35 connected to these packed valves 26 where no heat insulating material can be attached are directly exposed to the outside. is prevented. Therefore, there is no need to cover the packed valve 26 with a dedicated heat-insulating cover to prevent dew condensation and heat loss, as in the conventional case. In other words, the side wall 2 of the main body 21
Since it is only necessary to attach one cover 28 for closing the opening 27 to 1a, the number of parts can be reduced.

[0021]

[Effects of the Invention] As described above, in the present invention, since the valve to which the piping is connected is provided inside the main body, the appearance of the main body is improved. In addition, since the cover that closes the opening formed on the side wall of the main body also serves as a cover to prevent condensation and heat loss from the valve, the number of parts can be reduced compared to when the valve is covered with a dedicated cover. be able to.
