In a multi-air conditioner type air conditioner in which one outdoor unit corresponds to the indoor unit, the piping and wiring occupy most of the interior of the outdoor unit because a plurality of sets of piping and wiring are led to the outdoor unit. become.

FIG. 1 is a perspective view of an outdoor unit B (hereinafter simply referred to as “outdoor unit B”) of a conventional multi-air conditioner type air conditioner described in, for example, Patent Document 1. Hereinafter, the outdoor unit B will be schematically described with reference to FIG.
As shown in FIG. 1, the outdoor unit B is roughly configured with various configurations inside a housing body member Y1 and a left front panel Y2 that are provided separately. That is, the casing body member Y1 and the left front panel member Y2 are combined to form a rectangular parallelepiped casing member, and various configurations are arranged inside the casing member.
The left front panel member Y2 is a left side adjacent surface (a surface pointed by an arrow L, hereinafter referred to as an arrow L from the left side of a predetermined surface (a surface pointed by an arrow F) of the casing member, It is formed over most of the left surface L) and is removable independently of the housing body member Y1 (see FIG. 2). Note that a member on one surface side (surface pointed by an arrow F) of the housing main body member Y1 is referred to as a right front panel member 1, and provided with an exhaust port 2 after heat exchange, for example. The left surface L is usually provided with a valve support 8 for supporting a plurality of valves for connecting pipes from the outside.

FIG. 2 is a perspective view of the outdoor unit B according to the conventional example with the left front panel member Y2 removed. The interior of the outdoor unit B will be described with reference to FIG.
As shown in FIG. 2, the interior of the outdoor unit B is divided into a space behind the left front panel portion Y2 (hereinafter referred to as an equipment storage chamber) and a space behind the right front panel member 1 (inside (Not shown).
Above the device housing chamber, an electrical box 4b (an example of an electrical unit) in which various circuits (an example of electrical components) including a control circuit are incorporated is provided. A terminal block member 5b is provided integrally with the electrical box 4b below the electrical box 4b. The terminal block member 5b has a plurality of terminal plates 6 (an example of a relay terminal) that can be connected to a wire guided from the outside of the outdoor unit B on one surface thereof. Moreover, wiring is made between the terminal board 6 and the circuit inside the electrical box 4b, that is, both are electrically connected.
An incorrect wiring check switch, a pump down switch, a display board and wiring (all not shown) are provided on the surface of the electrical box 4b, and the terminal plate 6 is directly connected to the surface of the electrical box 4b.

However, the above-described conventional technique has the following problems.
First, the electrical board 4b must be provided in a shape protruding the terminal block member 5b downward. However, it takes time to manufacture the electrical box 4b having such a complicated shape, and there is a problem that packing work such as transportation is difficult.
Further, various wirings and pipes are usually provided also in the rear space RS of the terminal block member 5b provided below the electrical board 4b. Therefore, during the manufacture and maintenance of the outdoor unit B (particularly during parts replacement, etc.), various operations for piping, wiring, etc. occupying the rear space RS with the electrical box 4b mounted in the equipment housing chamber. Must be given. However, since the rear space RS is behind the terminal block member 5b provided integrally with the electrical box 4b, there is a problem that it is difficult to work on such piping and wiring. In the multi-air conditioner type air conditioner as described above, the compressor 7 and the piping and wiring are also provided in the space BS below the rear space RS. It is also impossible to work by inserting
Therefore, as described above, the left front panel member Y2 (exterior lid member) that can be removed from the casing member of the outdoor unit B is as follows to enable work on piping, wiring, and the like that occupy the rear space RS. It is formed over most of the left surface L. That is, in the state where the left front panel member Y2 is removed, most of the left surface L is opened, so that a hand can be inserted into the rear space RS from the opened position and work on piping, wiring, etc. can be performed. Is possible.
By the way, in the outdoor unit in a single-separated air conditioner type air conditioner, the amount of piping formed inside the main body exterior is small, so that the work can be sufficiently performed even if the open side of the left side L or the like is small. That is, in a single-separated air conditioner type air conditioner, in most cases, the open portion of the side surface such as the left surface L is provided small.
As described above, due to the difference in size of the open portions that must be provided in advance, the shape of the casing member in the multi-air conditioner type and the shape of the casing member in the single separate air conditioner type are different. Therefore, the mold for manufacturing the casing member cannot be shared by the multi-air conditioner type air conditioner and the single separate type air conditioner, which increases the cost of mold investment. There are also problems.
Accordingly, the present invention has been made in view of the above circumstances, and the object thereof is to simplify the shape of the electrical box and the terminal plate member, and the piping and wiring that occupy the shadow of the terminal plate member. Provide an outdoor unit for an air conditioner that can be used in common for the multi-air conditioner type and the single-separated air conditioner type to manufacture the exterior parts of the main unit. There is to do.

In order to achieve the above object, the present invention provides an exterior lid member which is a part of the front surface of a main body exterior member (main body housing) and is provided so that an inner device storage chamber can be opened, and is provided above the device storage chamber It is a outdoor unit of an air conditioner and a electrical unit which electrical components are built, the terminal block member which relay terminals are provided for connecting the electrical components and electrically connected and a wiring led from the outside (In a state where the relay terminal is opposed to the open position by the exterior lid member below the electrical unit ) and removal (from the open position) are possible, and the terminal block member is removed. configured as an outdoor unit of the main body outer front surface of the open portion from the pipe provided on the back side of the space of the terminal block members of the machine housing chamber space can work for wiring is wider air conditioner It is.
In the space on the back side of the terminal block member (from the portion opened by removing the exterior lid member, the space behind the terminal block member), various pipes and wiring are usually made, It is necessary to perform various operations on the piping and wiring in a state where the electrical unit is attached to the main body casing. According to the above configuration, the terminal block member can be removed independently of the electrical unit, and the work on the space behind the terminal block member can be easily performed by removing the terminal block member. Is possible. Further, the terminal block member and the electrical unit may be provided separately and independently, and typically a simple member such as a rectangular parallelepiped member and a plate member can be used. Of course, these members do not require much time for production and are easy to pack during transportation.
Further, even in the case of an outdoor unit in a multi-air conditioner type air conditioner, it is not necessary to have a configuration in which most of the side surface of the main body exterior member can be opened for work on the space on the back side. In the single-separated air conditioner type air conditioner with a small opening on the side surface of the exterior member, it is possible to share the mold used for manufacturing the exterior unit and the main body exterior member, thereby reducing the cost of mold investment. Is possible.

Here, when the terminal block member is attached at a position close to the inner side surface of the exterior lid member in the equipment housing chamber, a large work space is formed on the back side of the terminal block member. The true value of is easy to be demonstrated. Further, when the terminal block member is attached, it is preferable to have a guide for guiding the terminal block member to a predetermined attachment position because errors in the attachment position and procedure are reduced.
By the way, in the case where a plurality of the relay terminals are arranged in a substantially horizontal direction with the terminal block member attached, the relay terminal faces the attachment side surface of the terminal block member. Wiring should be avoided. Therefore, when the electrical unit is provided in the upper part, the terminal block member is attached to a lower position with a predetermined gap therebetween, and the relay terminal of the terminal block member is connected through the gap. It is possible to bypass the wiring on the back side of the mounting side surface.

  According to the present invention, the terminal block member can be removed independently of the electrical unit. Therefore, by removing the terminal block member, it is possible to easily work on the piping and wiring provided in the space behind the terminal block member. In addition, the terminal block member and the electrical unit can be provided separately and separately, and it is possible to use a simple member for each. Furthermore, even in the case of an outdoor unit in a multi-type air conditioner, it is necessary to have a configuration in which most of the side surface of the main body exterior member can be opened in order to perform work on piping, wiring, and the like provided in the back side space. Therefore, it is possible to share the mold used to manufacture the exterior and the outdoor unit in a single-separated air conditioner type air conditioner with a small opening on the side of the exterior of the main body. It is possible to suppress.
