The present invention will be explained in more detail below with reference to embodiments shown in the drawings. In the following description, "left" and "right" are based on the state in which the room is viewed from outside.

First, Figures 3 to 5, Figures 10 and 11
To outline the entire structure using the drawings, exterior panel units 2 are disposed on the outdoor surface of a frame slab 1, extending above and below the frame slab. This unit 2
Exterior panels 2a are arranged horizontally on the outer surface of the housing. A fixed glass window 3 is arranged in the height direction of the exterior panel unit 2, and the above-mentioned wall-through unit type air conditioner 4 is installed on the upper waist wall of the frame slab 1 on the indoor side of the exterior panel unit 2. It is being The exterior panel unit 2 is
It is supported by mullions 5 and the like. Top, bottom, left and right frames 6A-6
It is attached to the outdoor side of D, and an outside air intake port 2A and an exhaust discharge port 2B are opened at approximately the height of the slab 1, separated from each other to the left and right.

Further, a reinforcing bone 7 is provided across the left and right frames 6C and 6D at the center in the height direction. 8 is an intermediate mullion.

Now, to explain in more detail with reference to other drawings, an air supply/exhaust box section B is provided at a waist wall 9 on the indoor side of the exterior panel unit 2 and on the outdoor side of the air conditioner 4. This supply/exhaust box part B
On the top surface, as shown in FIG. 7, the upper frame 6A,
It is divided by an upper plate 10 and an upper through-shaped material 11, and on the lower surface, as shown in FIG. 6, it is divided by a drainer 12 and a lower through-shaped material 13, and on the left and right surfaces, as shown in FIG. and the right side plate 15, and the front side is partitioned by the aforementioned exterior panel 2. Further, as shown in FIG. 9, the back surface is divided by a first back panel 16, a second back panel 17, and an exhaust guide member 18 having a U-shaped cross section. ,12
The portion surrounded by the left and right through-shaped members 19, 20 and the intermediate partition member 21 having a substantially rectangular cross section has an intake communication hole 22 on the upper and lower sides in the height direction and an exhaust communication hole 23 on the upper side. On the other hand, on the outdoor side of the air conditioner 4, an exhaust port 24 and an intake port 25 (shown in FIG. 10) are formed above and below, corresponding to the intake and exhaust communication holes 22 and 23. .

As shown in FIG. 7, the bracket 26 that supports the exhaust guide section 18 also supports a panel holding horizontal frame 27 located above the outside air intake port 2A and the exhaust outlet port 2B on the back side of the exterior panel 2. . 7th
As clearly shown in the figure, as shown by the imaginary line in FIG. 3, the air intake side and the exhaust air are connected across the horizontal frame 27 and the outer surface of the intermediate partition member 21, approximately in the right half of the air supply and exhaust box section. An upper and lower partition plate 28 that partitions the two sides is provided astride the front and downwardly inclined state.

Further, the above-mentioned intake communication hole 22 and exhaust communication hole 23 have a pivot point at the upper end on the outdoor side, and the lower end is opened by being flipped up to the outdoor side by a mechanism described later. Lid body 3
0 and 31 are attached respectively. The lids 30 and 31 are open when the air conditioner 4 is in operation.

In the device configured in this way, outside air necessary for air conditioning enters the intake chamber P from the outside air intake port 2A, and at this time, the existence of the upper and lower partition plates 28 prevents the air from rising, and the air flows through the air intake communication hole 22 into the air conditioner 4. The exhaust gas enters the interior through the intake port 25, and the exhaust from there passes through the exhaust port 24, the exhaust communication hole 23, reaches the exhaust chamber Q on the upper and lower partition plates 28, and then from the guide chamber R in front of the exhaust guide section 18. It is discharged to the outside of the room from the exhaust outlet 2B via the outlet S.

Note that 33 is a defense rod fixed to the outside air intake port 2A and the exhaust outlet 2B by mounting brackets 34, respectively, in order to prevent birds from flying in.

On the other hand, the above-mentioned air conditioners are usually installed in offices within buildings and are not used at night or on holidays. When the air conditioner 4 is not in operation, if rainwater enters the air conditioner due to the wind, it may rust or rust.
In winter, condensation and freezing may occur, damaging the air conditioner 4. Therefore, in this case, the intake communication hole 22 and the exhaust communication hole 23 are closed by the lids 30 and 31, respectively.

The opening/closing mechanism of these lid bodies 30, 31 is shown in FIGS. 1 and 2. To explain this, an operation rod 50 serving as an opening/closing operation section is provided so as to be vertically movable through a holder 51.
The holder 51 is held by a bracket 52 attached to the upper plate 10, and has a fixing pin 54 at its upper end to which an operating handle 53 constituting an operating end is pivotally attached. In addition, in the intake communication hole 22, a bearing 55A, only one of which is shown, is mounted on the lower through-shaped member 13.

A guide lever 60A is fixed to a pin 59A protruding from the guide lever 60A through an elongated hole 60a.

On the other hand. A first link 61A is integrated with one end of the link shaft 56A, a second link 62A is pivotally connected to this with a pin, and the other end of the second link 62A is
It is pivotally connected to a bracket attached to the indoor side of the lid 30 by a pin 63A. Although not shown in FIG. 2, the lid body 30 is wide and it is a heavy burden to open and close it in one place.
are similarly arranged.

Further, a similar mechanism is provided inside the exhaust communication hole 23, but it will not be explained again, and the same number will only be given the same number and a "B".

Further, a pin 6 is provided at one end of the holder 50.
4, an operating handle 53 serving as an operating end according to the present invention is pivotally connected to the operating handle 5.
The position above the pin 64 of No. 3 and the upper end of the operating rod 50 below the pin 64 are pivotally connected at both ends by pins 66, 67 by a pair of bell cranks 65, 65. Further, the operating handle 53 protrudes above the waist decorative panel 67 and faces into the room.

In the opening/closing device for the intake communication hole 22 and the exhaust communication hole 23 configured in this way, the operating handle 53 in the closed state position shown by the solid line in FIGS. 1 and 2 can be turned sideways indoors to the imaginary line position. Then, as the bell cranks 65, 65 descend, the operating rod 50 descends. the result,
The pins 59A, 59B are lowered and the guide levers 60A, 60B are rotated counterclockwise in FIG.
Rotate B in the same direction. Along with this, the second links 62A, 62B are connected to the first links 61A, 61B.
The cover bodies 30 and 31 are moved to the outdoor side so as to be linear with each other, thereby opening the respective cover bodies 30 and 31. Conversely, when the operating handle 53 is returned to its original position, the lids 30 and 31 close, closing the intake communication hole 22 and the exhaust communication hole 23. In this state, outside air and rainwater do not enter the air conditioner 4.

[Effect of idea]

As described above, according to the present invention, it is possible to prevent outside air, rainwater, noise, etc. from entering the air conditioner and even indoors during strong winds, heavy rain, or at night. Unlike the case where the air supply/exhaust communication holes are arranged horizontally, since they are arranged vertically, the opening/closing operation can be performed by a common opening/closing operation part (for example, an operating rod) arranged in the vertical direction. Regarding this latter point, an air conditioner generally spans almost the entire length of the room, and if the air supply and exhaust holes are lined up horizontally as in the above publication, the operating rods will be placed horizontally and the operation will be controlled. Although it is necessary for the end to protrude into the room for operation from within the room, it is often difficult to ensure the length of the protrusion due to space constraints, and the operating position is unnatural. On the other hand, according to the present invention, if the operating rod is arranged along the vertical direction and its upper end is made to protrude above the waist wall, it is excellent in terms of operability.
