Abstract

PURPOSE:To facilitate a mounting operation by detaining a piece of coupling fittings which are previously coupled to hanging bolts to the outer part of the housing of the air cleaner and fixing the piece by means of a fixer from an inner side of the housing with the hand inserted from a lower blowing port. CONSTITUTION:The mounting work of the body 1 is executed by first fixing the hanging bolts 7 and a piece of the coupling fittings 8 by means of a nut from an aperture 12 of a ceiling. The body 1 is then risen by a lift, etc., and the pawl 9 of the other piece of the coupling fittings 8 is hooked to the hole on the side face of the housing of the body 1 and is positioned; thereafter, a hexagon headed bolt 11 is screwed to the welding nut 10 of the coupling fittings 8 by inserting the hand from the aperture 6 side of the body 1. Finally, an ornamental grille is mounted to cover the aperture 6 of the body 1 and the aperture 12 of the ceiling. The air in the chamber is sucked form the central part on the rear surface of the body 1 and is cleaned by a dust collecting unit 4. The cleaned air is blown out of the aperture 6 into the chamber.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mounting device for a ceiling-embedded air cleaner that connects the outside of an outer casing to a hanging bolt using a joining fitting.

BACKGROUND OF THE INVENTION In recent years, with the increasing awareness of airtightness and hygiene in buildings, the use of air purifiers has increased, and in offices in particular, air purifiers that are recessed into the ceiling are often used.

Conventionally, this type of mounting device for an embedded air cleaner has a configuration as shown in FIGS. 3 and 4.

That is, an L-shaped coupling fitting 102 is fixed to the outer surface of the outer casing of the main body 101 of the air purifier, and the coupling fitting 102 is fixed to a suspension port 1Q3 in the ceiling with a hexagonal nut 104 to suspend the main body 101. .

This installation work involved inserting hands and tools into the gap between the outer periphery 105 of the lower part of the main body 101 and the opening surface 106 of the ceiling to tighten it.

After fixing the main body 101, a decorative grille 107 was attached to cover the ceiling opening surface 106.

Problems to be Solved by the Invention In such a conventional configuration, the ceiling opening surface 106 is made as small as possible to reduce the area of the decorative grille 107 on the ceiling, so the gap to insert hands during installation work is small. However, the fixing work and height adjustment are not easy, and the fixing work is difficult because the work is done at a high place.

The present invention solves these problems by providing a ceiling recessed air purifier that can be easily installed even if the area of the ceiling opening is small and the gap between the ceiling opening and the main body is narrow. The object of the present invention is to provide a mounting device for a type air cleaner.

Means for Solving the Problem In order to solve this problem, the present invention makes the lower part of the air purifier correspond to the opening surface of the ceiling, and connects the side part of the outer casing of the air purifier to the hanging bolt via a connecting fitting. The configuration is such that
The air purifier has a built-in blower and a dust collection unit in the center of the lower part, and has an opening that also serves as an air intake port between the dust collection unit and the side of the outer casing, and the coupling fitting is It is formed in an L shape, one piece of which is connected to a hanging bolt, and the other piece of the connecting metal fitting is placed outside the outer casing of the air purifier,
It has a structure that is fixed from the inside of the outer casing.

Function: With this configuration, a piece of the coupling fitting that has been previously connected to the hanging bottle tV) is latched to the outside of the outer casing of the air purifier, and is inserted through the opening at the bottom of the air purifier that also serves as the air outlet. This involves inserting one's hand and fixing the coupling fitting to the outer casing using a (screw) stator from the inside of the outer casing of the air purifier.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. As shown in the figure, a blower section consisting of blower blades 2 and a motor 3 is provided in the center of the main body 1 of the air cleaner, and a dust collection unit 4 for removing dust is arranged below the blower section. An opening 6 is formed between the inner circumference of the outer casing of the main body 1 and the dust collecting unit 4, and serves as an outlet for blowing out clean air.

On the other hand, a plurality of hanging bolts 7 are vertically installed adjacent to the outside of the main body 1, and a piece of L-shaped coupling fitting 8 is fixed to the tip of the hanging bolt 7 with a nut. The other piece of the coupling fitting 8 is connected to the outer side 1 of the main body 1 by a hexagonal bolt 11 screwed into the welding nut 10 from the inside of the main body 1.

Further, a decorative grille 13 is provided to cover the opening 6 of the main body 1 and the opening 12 of the ceiling.

In the above configuration, the installation work for the main body 1 is performed by first fixing the hanging bolt 7 and one piece of the coupling fitting 8 with nuts through the opening 12 in the ceiling.

Next, the main body 1 is raised using a lift or the like, and the coupling fitting 8 is
After positioning the claw 9 of the other piece into the hole on the side of the outer casing of the main body 1, insert your hand from the opening 8 side of the main body 1 and screw the hexagonal bolt 11 into the welding nut 1o of the coupling fitting 8. Fix it with a stopper. Finally, attach the decorative jig IJ)
The opening 6 in the main body 1 and the opening 12 in the ceiling are covered.

Indoor air is taken in from the center of the lower surface of the main body 1, purified by the dust collection unit 4, and blown into the room from the opening 6 of the main body 1.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the fixing and installation of the air purifier main body can be adjusted from the main body opening, so that the gap between the outer periphery of the main body and the ceiling opening is small. Accordingly, it is possible to realize an excellent mounting device for a ceiling-embedded air cleaner, which has the effect that installation work can be easily performed even when the air cleaner is installed in the ceiling.
