Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an opening / closing structure for opening and closing an inspection opening of an air conditioner provided in a building.

[Conventional technology]

In the centralized air conditioner that has been conventionally used, since the air conditioners are centrally installed in the air conditioning room in the building, there is no need for an inspection port.

On the other hand, when the terminal air-conditioning system is selected as the individual air-conditioning of the intelligent building, the air conditioners are not centrally centralized unlike the conventional ones, but are arranged close to each living space. In this case, since the air-conditioning inspection opening cannot be provided facing the living space, the maintenance space problem can be solved by providing the inspection port on the corridor side, which is a common part, as an example.

However, in this case, it is necessary to open the wall of the air conditioner facing the corridor, which is a common area, almost entirely. After the inspection is completed, the large-area opening must be closed tightly and airtightly to maintain the sound insulation effect. For this purpose, it is necessary to make the inspection door an airtight door such as an airtight door, but a protrusion such as a clemon handle for securely closing the door and a hole for a lock bolt are required, and the door facing the corridor is required. As a result, it has a harmonious appearance.

[Issues to be solved by the device]

In consideration of the above facts, the present invention is similar in appearance to a general steel partition, and when the inspection port is closed, maintains airtightness and obtains an inspection port opening / closing structure with excellent sound insulation. Is the purpose.

[Means for Solving the Problems]

According to the present invention, a door for closing an inspection opening of an air conditioner, a shaft support means for pivotally supporting the door to open and close the inspection opening, and a door attached to either one of the door and the periphery of the inspection opening for closing the inspection. And a magnetic force closing member that closes the inspection port airtightly by magnetically adhering to the other.

Therefore, in the present invention, even when the inspection port has a large area, it is not necessary to provide a lock handle or the like on the opposite side of the door from the air conditioner, for example, on the corridor side. It is hermetically closed. When opening the inspection port, if the door is rotated against the magnetic force of the magnetic closing member, the inspection port can be easily opened for maintenance.

[Example of device]

FIG. 2 is a plan view of a building 12 to which the present invention is applied. This building 12 has a living space 14 and a bulkhead 16 with an approximately U-shape.
It is divided into a shared corridor 18 by. An elevator 22, stairs 24, hot water supply room 26, etc. are arranged in the U-shaped shared corridor 18.

An entrance / exit 28 is partially provided in the partition wall 16 at an intermediate portion in the longitudinal direction for moving between the living space 14 and the common corridor 18. The doorway 28 is provided with a door as required.

A machine room 32 is formed in the partition 16 and an air conditioner is installed. The air conditioner in the machine room 32 is provided with an air conditioner for maintaining each living space 14 at a desired temperature, and an outlet and a suction port are provided facing the living space 14 (not shown).

On the other hand, on the shared corridor 18 side of the partition wall 16, a frame body 34 assembled from a plurality of shape members is provided on the ceiling as shown in FIGS.
Secured to 12A and floor 12B. Opening 34A of this frame 34
Is an inspection port of the machine room 32, and an operator can inspect and repair the machine room 32 from the shared corridor 18 side.

As shown in FIG. 4, a box-shaped upper bracket 36 and a lower bracket 38 are attached to the side wall of the frame 34. This mounting is performed by screwing the mounting bolts 44 to the frame 34 through the long holes 42 formed in the upper bracket 36 and the lower bracket 38, which makes it possible to adjust the height of the upper bracket 36 and the lower bracket 38. Has become. Upper bracket 36
Arms 46 project toward the shared corridor 18 side from the upper end of the lower bracket and the lower end of the lower bracket 38, respectively. These arms
The pin 46 pivotally supports the door 52 with a pin 48. Since the pin 48 has a vertical axis and supports one side of the door 52 in the left-right direction, the door 52 can be opened and closed around a vertical axis (arrow A).
direction).

On one side of the door 52 facing the machine room 32, a magnet rubber 54 having a substantially U-shaped cross section is arranged with its longitudinal axis being a rectangular frame shape. The magnet rubber 54 has leg portions 54A protruding in opposite directions from the U-shaped tip portion, and a pin 56 is attached to the leg portion 54A.
Is applied and fixed to the door 52. Further, this magnet rubber 54 has a large number of magnet powder embedded in the rubber,
As shown in the drawing, the door 52 and the opening 34A are hermetically sealed by closely contacting the frame 34 at the peripheral edge of the opening 34A. Further, since the magnet rubber 54 is U-shaped and elastic, the airtightness is sure and the door 52 can be easily rotated against the magnetic force by manually applying a rotational force to the door 52 when opening. There is.

As shown in FIG. 3, an extension portion 52A having a substantially horizontal horizontal section is formed near the pivotal support portion of the door 52 toward the adjacent door 52 to reduce a gap between the adjacent doors 52. Further, since the pin 48, which is the pivotal support portion of the door 52, is arranged not in the center of the door 52 in the thickness direction but in the shared corridor 18 away from the machine room 32, even when the door 52 is opened. The arrangement is such that the extension portion 52A does not interfere with the tip portion of the adjacent door 52.

A heat insulating and sound insulating material such as glass wool is embedded inside the door 52 and between the plurality of frames 34.

Below the door 52, the Ajista 62 is placed to close the door 52 and the floor 12B.
The gap between and is closed. The height of the adjuster 62 can be changed by adjusting the screwing amount of the internal adjusting bolt 64.

In the present embodiment configured in this way, when inspecting the machine room 32, when the operator manually pulls the door 52 from the shared corridor 18 side, the magnet rubber 54 of the door 52 resists the magnetic force to frame the frame. Separate from the body 34 and open the opening 34A. For this reason machine room 3
The inspection and repair of 2 can be easily performed from the common hallway 18 side.

After the inspection and repair are completed, the door 52 is rotated in the opposite direction and the magnet rubber is again rotated as shown in FIGS.
When the frame 54 is brought into close contact with the frame 34, the opening 34A is closed. The magnet rubber 54 is elastic and has a door 52 and an opening 34.
Airtightly closes with A. Further, since the door 52 faces the shared corridor 18 side and has no lock handle or the like, the surface of the door 52 can have an appearance similar to that of a general steel partition.

[Effect of device]

Since the present invention is configured as described above, it has an excellent effect that the appearance is similar to that of a general steel partition and the inspection port of the air conditioner can be closed airtightly.
