Can be checked while.

  By the way, of the first opening / closing door 91 and the second opening / closing door 92, the second opening / closing door 92 can be freely opened and closed, and there is no restriction on access to the article storage shelf 70. On the other hand, since the first door 91 is provided on the lower side, even a child such as an infant can be opened and closed. In this case, since the access to the air conditioner 41 becomes possible when the first opening / closing door 91 is opened, there is a risk that the air conditioner 41 may be erroneously operated by a child. Therefore, an opening restricting means for restricting the opening of the first door 91 is provided.

  As shown in FIG. 4, a stopper member 93 is attached to the back surface of the first door 91, that is, the surface that is inside the air conditioning machine room 12 in the closed state. One stopper member 93 is provided on each of the left and right door plate members 91a and 91b. Referring to FIG. 2, the stopper member 93 is attached to the upper end of the left and right center and below the front rod 83 when the first door 91 is closed.

  The stopper member 93 is formed by bending a metal plate material, and includes an attachment portion 94 to the door plate members 91a and 91b, a horizontal portion 95, a locked portion 96, and a distal end portion 97. The horizontal portion 95 extends horizontally from the mounting portion 94 below the front rod 83 and has a longer dimension than the front rod 83. The locked portion 96 is formed by raising the tip of the horizontal portion 95 at a right angle. The tip of the locked portion 96 is a tip portion 97 extending obliquely downward.

  On the other hand, a stopper pin 98 is provided on the front side of the lower surface of the front rod 83. The stopper pin 98 is provided so as to protrude from the lower surface of the front rod 83 so as not to interfere with the horizontal portion 95 of the stopper member 93. When the first opening / closing door 91 is opened, the opening of the first opening / closing door 91 is restricted by the locked portion 96 of the stopper member 93 hitting the stopper pin 98.

  The mechanism of the opening restriction will be further described with reference to FIG. FIGS. 6A and 6B are explanatory diagrams schematically showing the opening restriction of the first opening / closing door 91 and the state of release thereof, in which FIG. 6A shows a state in which both opening / closing doors 91 and 92 are closed, and FIG. 6B shows the first opening / closing door. A state in which the opening of 91 is restricted, (c) shows a state in which the opening restriction of the first door 91 is released. In addition, in this FIG. 6, although the left door plate member 91b, 92b is shown among the left and right door plate members 91a, 91b, 92a, 92b which comprise each door 91, 92, the right door plate member 91a, The opening restriction is also applied to 92a by the same mechanism.

  As shown in FIG. 6A, in a state where both the doors 91 and 92 are closed, the locked portion 96 of the stopper member 93 is located behind the stopper pin 98. From this state, when only the first opening / closing door 91 is to be opened by the double door opening method, the left door plate member 91b of the first opening / closing door 91 moves forward.

  Then, as shown in FIG. 6 (b), the locked portion 96 of the stopper member 93 hits the stopper pin 98, and the left door plate member 91b is restricted from opening more than that. At this time, since the second opening / closing door 92 (left door plate member 92b) in the closed state exists above the horizontal portion 95 of the stopper member 93, the engagement between the locked portion 96 and the stopper pin 98 is released. Can no longer do. In other words, the space generated by the movement of the left door plate member 91b of the first door 91 is closed by the left door plate member 92b of the second door 92, and the stopper member 93 can be operated. It is gone. Therefore, as long as the second door 92 is closed, the first door 91 cannot be opened.

  Incidentally, in order to have the above-described configuration, the horizontal portion 95 of the stopper member 93 has a length L from the mounting portion 94 to the locked portion 96 that is equal to the thickness of the left door plate member 92b of the second door 92. The length from the front surface of the front rod 83 to the contact surface of the stopper pin 98 with the locked portion 96 is set to be substantially the same.

  When releasing such an opening restriction, as shown in FIG. 6C, first, the second door 92 is opened. Then, by pushing the horizontal portion 95 of the stopper member 93 downward, the locked state between the locked portion 96 and the stopper pin 98 is released. Thereby, since the opening restriction is released, the left door plate member 91b of the first door 91 can be opened.

  When the pressing of the horizontal portion 95 of the stopper member 93 is stopped, the horizontal portion 95 returns to the original horizontal state by the restoring force. For this reason, when closing the left door plate member 91b of the first opening / closing door 91 from the opened state, the horizontal portion 95 is pushed down again, and the locked portion 96 and the stopper pin 98 are avoided from contacting each other. Will be closed.

  Thus, unless the second door 92 is opened, the lower first door 91 cannot be opened. And since the 2nd door 92 is on the upper side, it is difficult for children, such as an infant, to open and close. For this reason, it can suppress that the 1st opening / closing door 91 which enables access to the air conditioner 41 is opened by the child, and can reduce a possibility that the child may misoperate with respect to the air conditioner 41.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  An article storage shelf 70 is provided in the air conditioning machine room 12, and the article storage shelf 70 has a storage space 74 formed by a bottom shelf portion 71, a top plate 72 and a back surface portion 73. As described above, the storage space 74 is partitioned vertically and horizontally, and the back side, so there is no possibility that the articles stored in the article storage shelf 70 are dropped into the space in which the air conditioner 41 and the like are stored. For this reason, the user-friendly storage space 74 is secured, and effective use in the air conditioning machine room 12 can be achieved.

  And if the storage space 74 is provided in the state where the periphery was partitioned in this way, the air-conditioning equipment installed in the back will be hidden. However, an inspection port 77 and an inspection port lid member 78 that detachably closes the inspection port 77 are provided on the back surface portion 73 of the article storage shelf 70. When the article storage shelf 70 is used, the inspection opening 77 is provided with an inspection opening lid member 78. When the air conditioning equipment needs to be inspected, the inspection opening lid member 78 is removed, whereby the air conditioning equipment can be inspected. Therefore, it is possible to secure an easy-to-use storage space 74 in the air conditioning machine room 12 while suppressing troubles in inspection.

  The inspection port 77 can visually recognize a connection portion in the ventilation member 42. That is, the inspection port 77 is a relatively large opening and is disposed on the lower side in the back surface portion 73. Therefore, the inspector can put the head into the inspection port 77 and look into the back, and can inspect while looking down at the connection part or looking up. The connection portion in the ventilation member 42 is a portion that needs to be visually confirmed when checking the air conditioning system 40, such as whether there is leakage of conditioned air, and can prevent the inspection from being hindered.

  The article storage shelf 70 is provided with a detachable movable shelf 76. Therefore, by partitioning the storage space 74 with the movable shelf plate 76, the storage space 74 can be used effectively. And since the movable shelf board 76 is removable, if it removes at the time of the inspection of air-conditioning equipment, it will avoid that the trouble using the inspection port 77 arises.

  An article storage shelf 70 is provided in front of the upstream-side ventilation portion 51 of the ventilation member 42, and is below the article storage shelf 70 and in front of the air conditioner 41 placed on the floor, as a first space 61 as an inspection space. The article storage shelf 70 is provided while securing the above. The first space 61 can be used to inspect and operate the air conditioner 41, and the space can be used effectively without obstructing access to the air conditioner 41.

  Since the article storage shelf 70 is provided above the first space 61, the inspection port 77 is disposed at a higher position. In addition, the inspection port 77 provided in the back surface portion 73 exists in a recessed position. For this reason, it becomes difficult for the inspector to approach the inspection port 77 and inspect the air conditioning equipment.

  In that respect, the bottom shelf 71 of the article storage shelf 70 has load resistance against human weight. For this reason, it becomes possible to inspect the air conditioning equipment from the inspection port 77 in a state where the inspector is placed on the bottom shelf 71, and the inspection work can be easily performed.

  The article storage shelf 70 has the same ceiling height as the falling ceiling of the hallway 11 on the ceiling side. For this reason, the ceiling side of the article storage shelf 70 is set as high as possible, and a wider storage space 74 can be secured.

  The article storage shelf 70 is provided with a second opening / closing door 92 that is a double-folding double door. Therefore, the left and right door plate members 92a and 92b can be individually opened and closed, and the usability of the article storage shelf 70 can be improved as compared with the case where the second opening and closing door 92 is configured by a single door.
