As a result of this arrangement, the maintenance work can be easily performed without removing the decorative grille wholly and the diffusing grille can also be cleaned easily.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a ceiling-embedded air cleaner.

Conventional technology In recent years, as buildings have become more airtight and hygiene awareness has increased, air purifiers have become more common, and in stores and ice cream parlors, models that are recessed into the ceiling are increasingly being used. .

Conventionally, this type of embedded air purifier is shown in Figs. 3 to 5.
The configuration was as shown in . That is, the lower surface of the main body 101 of the embedded air cleaner and the opening surface of the ceiling are covered with a decorative grille 102.

Then, the contaminated air suction grill 103 provided in the center of the decorative grill 102 is made openable and closable, or detachable.
Only the dust collection unit (104) had to be taken out from the main body during maintenance and inspection. Further, a blow-off grill 105 from which purified air is blown out is integrally formed with the decorative grill outside the suction grill 103.

An electrical box 106 was attached inside the air outlet grill 105 inside the main body 101.

Problems to be Solved by the Invention In such a conventional configuration, the internal electrical box 1
During maintenance and inspection of 06, it is necessary to remove the decorative grille 102, but since the decorative grille 102 is fixed to the main body 101 with screws and is large and heavy, it cannot be easily removed from the ceiling surface. Especially in modern offices, pachinko parlors, etc., many air purifiers are installed, and although it is important that they can be easily inspected, maintenance has been very difficult. Furthermore, when an embedded air purifier is used for a long period of time, not only the suction grill 103 but also the outlet grill 105 become gradually contaminated, but with the conventional configuration, the problem that the outlet grill A/105 cannot be easily cleaned is solved. had.

The present invention is intended to solve these problems, and aims to provide an air purifier in which maintenance work can be easily performed without removing the entire decorative grille, and the blowout grille can be easily cleaned. .

Means for Solving the Problems In order to solve this problem, the present invention provides an air purifier main body that is suspended from a ceiling girder, an electrical equipment box built into the main body, and an opening surface provided below the main body. ceiling board and
The electrical equipment box has a decorative grill that engages with the periphery of the opening surface and is fixed to the lower end of the main body, and an intake grill and an air outlet grill that are removably attached to the opening of the decorative grill, and the electrical equipment box It has a structure that allows it to be taken out from the opening of the sigrill.

Function: With this configuration, by removing the air outlet grille from the decorative grille, the electrical box built into the air purifier can be easily inspected and repaired, and the removed air outlet grille can also be cleaned by washing with water.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 to 3. That is, a blower section such as blower blades 2 and a motor 3 is provided in the center of the main body 1, which forms the outer casing of the air cleaner, and a dust collection unit 4 for removing dust is arranged below the blower section. A ventilation passage 6 for blowing out clean air is formed between the inner peripheral part of the outer casing of the main body 1 and the dust collection unit 4, and an electrical box 6 is attached to the main body 1 in this ventilation passage 6. On the other hand, the ceiling 7 is located at the lower end of the main body 1.
A decorative grille 9 is fixed to the main body 1 with screws so as to cover the opening surface 8 of the main body 1. This decorative grill 9 has an opening 1o, and an air suction grill 11 is attached to the center of the opening 1o, and on both sides of the suction grill 11, blow-off grills 12 for blowing out clean air are arranged on almost the same plane. are doing. And the suction grill 1 in the center of the decorative grill 9
1 can be opened and removed by a removable hinge 13, the blowout grille 12 can be opened by a latch 14, and the decorative grille 9 can be opened and removed.

In normal operation of the above configuration, dirty indoor air is sucked in through the suction grille 11, cleaned by the dust collection unit 4, and then blown into the room through the ventilation passage 5 of the main body 1. When cleaning the dust collection unit 4, such as replacing it, open the suction grill 11 and take out the dust collection unit 4. In addition, when maintaining or inspecting the interior of the main body 1 or electrical equipment such as the electrical box 6, the intake grill 11 can be removed by removing the hinge 13, and the air outlet grill 12 can be removed from the decorative grill 9 by removing the latch 14. can. In this state, the bottom surface of the main body 1 is opened, and the electrical box 6 can be easily taken out from the main body for repair and repair.
Inspection and repair can be performed easily.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, by removing the suction grill and the outlet grill within the decorative grille frame of the air purifier, the stain box can be removed from the inside of the air purifier. Easy to take out for repairs,
This makes it possible to realize an excellent ceiling-mounted air purifier that can be easily inspected and repaired, and the air outlet grill, which is easily soiled along with the suction grill, can be cleaned by washing with water.
