Abstract

PROBLEM TO BE SOLVED: To prevent dirt and scratches of an up-and-down flap in installing work, while almost preventing dust particles flying in an installing work place from getting in an air conditioner body, and to easily perform a drain check after installation without detaching a protective cover.SOLUTION: The protective cover 14 made of a flexible and airtight material blocks a whole opening part on the underside of the air conditioner body 1 having at least a built-in drain pan 7 and a suction opening 3 and a blowout opening 4 on the underside. The protective cover 14 has a notch near the drain pan 7 to form an inspection port with a finger catcher.

Description

  The present invention relates to an installation device for a ceiling-embedded air conditioner.

  Conventional ceiling-mounted air conditioner installation equipment is designed to prevent dust and other dust scattered at the construction work site from entering the main body of the ceiling-mounted air conditioner over the entire circumference of the end. A bag-like cover with a rubber string inserted is stretched and attached so as to cover the lower surface of the main body. Furthermore, in order to position the opening formed when constructing the ceiling material, the installation template to be mounted on the lower surface of the main body is covered with the screw for mounting the decorative panel using the screw for mounting the decorative panel. (See, for example, Patent Document 1).

JP 2008-175460 A (summary, FIG. 7)

  However, if a bag-like cover with a rubber string inserted over the entire circumference of the end is stretched and attached so as to cover the lower surface of the main body, the unevenness on the side of the main body (electrical component installation section and piping section) ) Cannot be brought into close contact with each other, and there is a problem that dust or the like scattered at the construction work site enters the main body through the gap.

  In addition, since the drainage check from the drain pan is performed after the installation of the main body, it has been necessary to remove part or all of the bag-like cover once and return to the original state after the drainage check.

  Further, since the screws for mounting the decorative panel are used for mounting the pattern for installation, there is a problem that workability is very poor.

  The present invention has been made to solve the above-mentioned problems, and it substantially blocks the intrusion of dust and the like scattered at the construction work site into the main body, and also stains and damages the upper and lower flaps during the construction work. The purpose is to make it possible to easily prevent drainage after installation without removing the protective cover.

  The ceiling-embedded air conditioner installation apparatus according to the present invention includes at least a drain pan, and has a flexible and air-tight structure that closes the entire opening of the lower surface of the main body having a suction port and an outlet on the lower surface. In the installation device for a ceiling-embedded air conditioner provided with a protective cover made of a material that does not pass through, the protective cover is provided with a notch in the vicinity of the drain pan for forming an inspection port with a finger hook. Is.

  In the ceiling-embedded air conditioner installation device according to the present invention, the protective cover is provided with a notch for forming an inspection port provided with a finger hook in the vicinity of the drain pan. It is possible to substantially block the intrusion of dust etc. into the air conditioner body, prevent dirt and scratches on the upper and lower flaps during construction work, and also check the drainage after installation without removing the protective cover, The inspection opening is opened by bending the remainder of the notch downward using a finger hook, and a drainage check can be easily performed while inserting a jug or the like through the inspection opening and pouring water into the drain pan. For this reason, the efficiency of the installation work is improved, and the installation work stable in quality can be performed.
