Description

[Detailed description of the invention] This invention relates to a ceiling-type air conditioner that is used by being suspended from the ceiling, or by being embedded in the ceiling.

Conventionally, in order to perform maintenance and inspection on the blower of this type of equipment, it was necessary to open the bottom panel or the inspection port, remove the blower inside the main body, or enter into a narrow ceiling, making it very difficult to operate. The work was extremely difficult and dangerous.

This idea was made in view of the above circumstances,
The objective is to provide a ceiling-type air conditioner that is highly operable and safe for workers.

An embodiment of this invention will be described below.

In Figures 1 to 3, reference numeral 1 denotes a ventilation unit formed between a ventilation lower' for air suction and a ventilation opening 5' for air blowout, which will be described later, so that the pair of ventilation openings communicate with each other. The main body is equipped with a blower device 2 and a heat exchanger 3 in a passage A, and 4 is a front panel equipped with a blow-off grill 5 attached to a ventilation opening 5' for blowing out air, which is attached to the main body 1. .

6 is an intake grill 7 attached to the ventilation lower' for air intake.
The rear panel is attached to the front panel 4 so as to be openable and closable with a hinge 8 and a set screw 8', and the indoor air sucked in from the intake grille 7 in the air intake ventilation lower 'is shown by the solid line arrow in FIG. 1. The air is drawn into the main body 1 by the blower 2, cooled or heated by the heat exchanger 3, and blown into the room from the air outlet grill 5 at the air outlet 5'.

The blower device 2 consists of a blower consisting of an electric motor 9 and a blower blade portion 10 driven by the blower, and an underframe 11 to which the blower is mounted with mounting screws 11'. Mounting hole 13.
13' by bolts 14 and 14', and when the bolts 14 are removed, they can be rotated around the bolts 14', that is, the fulcrum B.

Further, the underframe 11 partitions the inside of the ventilation passage A into two chambers in which the heat exchanger 3 and the blower are located, respectively.

In addition, the underframe 11 has a hole for inserting 14.14)
15.15' are fixed by means such as welding.

In addition, sufficient space is secured at the rear of the main body 1 for the blower 2 to rotate rearward about the fulcrum B (to the left in Figures 1 and 2, and to the front in Figure 3). , when the blower device 2 is rotated from a position where the underframe 11 partitions into a chamber housing the heat exchanger 3 and a chamber housing the blower, as shown in FIG. 2, to a position where the blower protrudes outside the main body 1. There is a locking piece 16 that prevents the underframe 11, that is, the blower 2 from rotating.
It is equipped with

The locking piece 16 is screwed onto the main body 1 by a screw 17, and therefore, the free end of the rear panel 6 is removably fixed to the main body 1 via the set screw 8', the locking piece 16, and the screw 17.

In the above configuration, if an abnormality occurs in the blower device 2,
Open the rear panel 6 to a position that allows the blower to protrude outside the main body 1, remove the bolts 14 that fix the blower 2, and loosen the bolts 14' to lock the main body 1 and the underframe 11. Unscrew the locking piece 1 by rotating the blower device 2 backward about the fulcrum B as shown by the dashed-dotted line arrow in FIG.
Lock it at 6.

At this time, the electric motor 9 and the blower blade portion 10 are connected to the suction lower'
The electric motor 9 and the blower blade portion 10 are maintained and inspected in this state.

When cleaning the heat exchanger 3, etc., operate the screw 17, remove the locking piece 16, rotate the blower device 2 further downward, and clean from the gap.

Note that locking by the locking piece 16 is a conventional means, and the locking piece 16 does not necessarily have to be removed; for example, if the screw 17 is long, the locking piece 16 can simply be moved along the screw 17 in the direction away from the main body 1. The locking of the underframe 11 can be released simply by moving the underframe 11, and this can be achieved by various conventional means.

If the entire blower device 2 is to be replaced, it can be taken out downward by removing the bolts 14 and 14'.

In the above embodiment, the blower device 2 is of suction type, so 5' is the air outlet and 7' is the suction port. There are two types. Therefore, if you use a blower type as the blower device 2, naturally 5' is the suction port,
7' becomes the discharge port.

Further, in this case, the relative positional relationship between the blower device 2 and the heat exchanger 3 must be the same as that in the above embodiment, otherwise the blower device 2 cannot protrude to the main body (outside).

As mentioned above, this invention consists of a main body that has a pair of ventilation holes for air intake and air blowout, and a body that forms a ventilation passage that communicates these pairs of ventilation holes, and a heat exchanger that is provided in the ventilation passage. a blower installed in the ventilation passage that blows air from the air suction opening to the air discharge opening via the heat exchanger; and a chamber for storing the blower, and the blower is pivotally connected to the main body so as to be pivotable from the partitioned position in a direction in which the blower projects from the - of the ventilation holes to the outside of the main body. an underframe, a panel that can be rotated by a hinge in a direction that allows the blower to protrude outside the main body, and whose free end is removably fixed to the main body at a position that covers a ventilation hole that allows the blower to protrude; and the blower. protrudes to the outside of the main body, and prevents rotation of the underframe at a position where the underframe covers the ventilation port, and furthermore, the underframe can also project to the outside of the main body together with the blower to open the ventilation port. As shown in FIG. Since it also has the following features, its configuration is simple.

In addition, by rotating the mounting frame of the blower, the blower protrudes from the inlet or outlet to the outside of the main body, so it is possible to service the blower from the outside of the main body with the blower mounted on the mounting frame. There is no need to take the blower out of the main body.

Therefore, maintenance and inspection of the blower can be easily carried out.
It is possible to obtain an air conditioner that is highly operable and safe for workers, especially in high positions.

Furthermore, a locking piece is provided that prevents rotation of the underframe at a position where the blower protrudes to the outside of the main body and the underframe covers the ventilation opening, and can further protrude the underframe together with the blower to the outside of the main body to open the ventilation opening. Since it is removably attached to the main body, it is also possible to clean the heat exchanger using the ventilation hole that allows the blower to protrude.
