Abstract

PURPOSE:To simply carry out maintenance and inspection by furnishing detachable orifice, blades, and a motor into the inner box in which electrostatic precipitating parts are incorporated, and providing an electric instrument part in a draft passage. CONSTITUTION:When a motor 29 is energized, the blades 30 are revolved, and the polluted air in a room is sucked from a suction grill 40 and the dust is removed in the electrostatic precipitating part 31, and the air is blowed out of blowing-out opening 37 into the room through the draft passage 36 of four directions by the blades 30. When the maintenance and inspection is to be carried out, the blowing-out grills 41 of both sides are removed after the suction grill 40 is removed. In this case, when the blowing-out grill 41 is inwardly sifted, the projected parts 44 is moved out of the holes 43 of a panel frame 42, and, at the same time, in the side of bulged holes 46, studs are moved from small holes 46a to the bulged holes 46 so that the blowing-out grill is allowed to remove downwards. By this method, the maintenance is easily carried out by one worker.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the equipment configuration of a ceiling-embedded air cleaner.

2. Prior Art As shown in FIG. 4, this type of air purifier has a main body 8 of the air purifier suspended from a hanging bolt 10 in the ceiling and exposed below the ceiling surface 11. The decorative spring /L/6 is fixed at multiple locations by the screws 13 of the fixing part 12, and inside the main body 8, there are blades 2 that connect the main body 8 and the decorative spring /L/6. The motor 1 is connected to the inner box 3 and is attached to the inner box 3 via three stays 4 to support the motor 1. A dust collector 6 is housed in the inner box 3, and the dust in the air sucked in through the suction port 6a formed in the decorative panel 5 is removed by the dust collector 6 and becomes clean. Air passes through the ventilation passages 14, 14 formed in four directions around the motor 1.
8 and was blown into the room through the air outlet 6. Further, the ventilation path 14 is provided with an electrical equipment section 7 .

Problems to be Solved by the Invention In such a conventional configuration, when maintenance inspection or replacement of the motor 1 or the air blower blade 2 is performed, a citrus bar or the like is inserted into the narrow air outlet 15 of the decorative spring/115 and the fixed part 12 is opened. Unless the decorative spring/I/6 is separated from the ceiling surface 11 and the main body 8 after removing the screws 13 at multiple locations, the dust collector 6, motor 12 blades 2. Maintenance work on the electrical equipment section 7 is impossible, and there is a problem in that two workers are required to remove the entire decorative panel 6.

The present invention solves these conventional problems, and aims to provide an air cleaner configuration that allows maintenance, inspection, and replacement of internal parts with simple operations.

Means for Solving the Problem In order to solve this problem, the present invention includes a main body in the attic of an opening in the ceiling surface, a decorative panel joined to the main body, and an electric collector in the main body. An inner box with a built-in dust part, an orifice that can be attached and detached from the inner box, a blade button and a motor that can be attached and detached when the orifice is removed, and an electrical part is provided in the ventilation path that communicates with the air outlet. The decorative panel has a suction grill in the center and a pair of blowout grilles μ on both sides, a panel frame is fixed to the main body, and the suction grille and the blowout grille are detachable. It is.

Operation With this configuration, when performing maintenance such as maintenance inspection or replacement of each part inside the υ main body, remove only the suction grill and outlet grill, perform maintenance on trench 1 with the panel frame fixed, and remove the orifice dog. This makes it possible to maintain all component parts such as blades and motors.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3. In Figure 1, hanging bolts 2 are installed in the ceiling 20.
1, a main body 22 of the air purifier is installed, and a button is pressed into an opening 24 of a ceiling surface 23, and the main body 22 and a decorative panel 25 are joined by screws 27 of a fixing part 26. Inside the main body 22, there is a mounting plate 2 on the inner top surface 27a.
A motor 29 is attached by reference numeral 8, and a blade 30 for blowing air is attached to the shaft of this motor 29. An inner box 3 containing an electrostatic precipitator 31 is located below the blade 30.
2, an inner box opening 33 having an outer diameter larger than the outer diameter of the blade 30 is formed on the top surface of the inner box 32, and an orifice 34 is inserted into the inner box opening 33 by a screw 35. is installed. Furthermore, an electrostatic precipitator 31 for removing dust from contaminated air is fitted inside the inner box 32.
A ventilation passage 36 is formed around the four sides of the inner box 32 and communicates with the air outlet 37 through the blades 3o.
An electrical equipment section 38 is provided on either one of the ventilation paths 36. On the other hand, the decorative spring Iv25 has a suction valve 9 that is removable at the center and is provided in contact with the air filter 39! J/I/40 and the air outlet on both ends of this suction grill 40! It is composed of J/l/41 and panel frame 42. The panel frame 42, the air outlet grille 1v41, and the suction grille 40 are joined in a configuration as shown in FIGS. 2 and 3. That is, the fixture 4 has a shape in which the projection piece 44 on one side of the blowing gun IJ/l/41 is inserted into the hole 43 provided in the panel frame 42, and the opposite side is integrated with the main body 22 side.
5 is provided with a dull shima hole 46, and the fixing screw 47 attached in advance to the blowout grate/l/41 slides into the small hole 46 & side of the dull shim hole 46.
I try to keep it at 1. In addition, the suction grill 40 is held by a holding piece 48 and is also held by a mounting means provided at the lower end of the inner box 32, although not shown.

In the above configuration, by energizing the motor 29,
When the blades 3o rotate, the indoor contaminated air sucked in from the suction grill 40 is removed by the electrostatic precipitator 31, and is energized through the blades 30 to the ventilation passages 3e on all four sides, and is blown out from the air outlet 37 into the room. Ru. Next time you perform maintenance work such as maintenance inspection or repair/replacement, use suction! After removing J/v40, blow out on both sides! JA/41 is removed, but at this time, the air blows inward (arrow A)! By sliding J/L/41, the projection piece 44 is removed from the hole 43 of the panel frame 42, and on the side of the daruma hole 46, it moves from the small hole 46a to the daruma hole 46, and can be pulled out downward. It is. In this way, the decorative panel frame 42 is attached to the ceiling surface 23, and the air filter 39. All parts including the electrostatic precipitator 31, the screw 36 removed from below and the orifice 34 removed 9, the blade 30, the motor 29, the electrical component 38, etc. can be inspected and replaced.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention involves joining a main body and a decorative panel facing the ceiling surface, removing the intake grill and outlet grill that form the decorative panel, and removing the panel frame from the it. Maintenance is extremely easy since each part inside the main body can be maintained while it is attached to the main body.Moreover, the inner box has a removable orifice that allows the blades to be attached and removed. Maintenance can be performed without the need to remove the box.

Also, if you remove the entire decorative panel as in the past, 2
Although a human operator is required, as in the present invention, only the suction grill and the outlet grill are removed while leaving the panel frame, so maintenance can be carried out sufficiently by one operator. be.
