Description

[Detailed Description of the Invention] This invention relates to an improvement of a ceiling-embedded humid air conditioner that is installed with its main body part embedded inside the ceiling.

A conventional device of this type is constructed as shown in FIG.

That is, in the figure, 1 is a main body installed inside the ceiling A, 2 is an air inlet 3 and an air outlet 4 formed on both sides thereof.
, 4, and 5 is a top panel attached to the air inlet 3 so as to be openable and closable, and an air passage is formed by a cut-out window 5a.

6 is a filter provided above the top panel 5; 7 is a louver device provided at the air outlets 4, 4 to adjust the air flow of the blown air; 8 is provided inside the main body 1; 4
, 4 and an inner frame 9 is formed within the main body 1,
This is an air ventilation passage that communicates the air inlet 3 and the air outlets 4, 4, and includes an inner air passage 9a through which the air sucked in from the air inlet 3 ascends through the inner frame 8, and an inner air passage 9a that is folded back upwards to form the main body 1. It is constituted by an outer ventilation passage 9b that descends through the gap with the inner frame body 8 and reaches the air outlet 4.4.

10 is a blower located above the suction port 3 and provided in the inner ventilation passage 9a, 11 is a heat exchanger located further above the blower 10 and provided in the inner ventilation passage 9a, and 12 is a heat exchanger. A dew pan provided between the container 11 and the blower 10, 1
Reference numeral 3 denotes a drain port for discharging the drain collected in the drain tray 12 to the outside, and is connected to a drain pipe (not shown).

14. 15 is a piping connection port for connecting inlet side piping and outlet side piping (not shown) for supplying cold water or hot water to the heat exchanger 11; 16 is a hanging bolt for suspending the main body 1 from the ceiling beam B; Reference numeral 17 denotes a mounting screw for mounting the exposed panel 2 on the main body 1.

With this structure, the exposed panel 2 has an air suction port 3 formed by a cut-out window 5a, and a filter 6 is installed above it, so that the dust in the air sucked in from the room can be removed. The dust adhering to the end face of the push window 5a was unsightly, and when the operation was stopped, the dust adhering to the filter 6 and the end face of the push window 5a fell into the room, making it unhygienic.

In addition, in terms of the performance of the air conditioner, dust adheres to both the filter 6 and the cut-out window 5a, resulting in a significant increase in air path resistance, resulting in problems such as reduced performance and increased performance. .

On the other hand, when installing the main body 1 and the exposed panel 2 inside the ceiling, work is performed with the openable top panel 5 provided at the air intake port 3 open, which impairs work efficiency and reduces safety. This was a measure that should be taken seriously.

This idea forms air ventilation channels on both sides of the top panel attached to the air intake, provides a filter above the top panel, and forms an air ventilation path between the filter and the top panel. This is an attempt to eliminate the above-mentioned drawbacks.

An embodiment of this invention will be described below with reference to FIGS. 2 and 3.

In the figure, 5 is a top panel that is attached to the suction port 3 and forms air passages 18 and 18 on both sides.One side is fixed to a hinge device 19 provided on the exposed panel 2, and the other side is fixed to a pin 20. It is configured so that it can be opened and closed by the hinge device 19 by engaging it and disengaging it from the pin 20.

A filter 6 is provided above the top panel 5 and forms an air passage 21 between it and the top panel 5, and is held by a filter support 22 fixed to the exposed panel 2. 23 restricts movement in the width direction and is configured to allow attachment and detachment from the filter support 22.

The size of the filter 6 is made smaller than the size of the top panel 5.

Reference numeral 17 denotes a mounting screw for mounting the exposed panel 2 on the main body 1, and the mounting operation is performed from the air passages 1B and 18 formed on both sides of the top panel 5.

Note that the other parts are given the same reference numerals as in FIG. 1, and their explanation will be omitted.

Next, this operation will be explained.

When the operation starts, the indoor air is drawn by the blower 10 through the passage 18.1B of the suction port 3, and then the top panel 5 and the filter 6.
The air is sucked into the filter 6 through the passage 21 between the air and the air, and is blown to the heat exchanger 11 through the inner ventilation passage 9a.

The indoor air blown to the heat exchanger 11 exchanges heat with the cold/hot water flowing inside the heat exchanger 11, becomes cold/warm air, and is blown out from the outlet 4 through the outside ventilation path 9b to cool the room.・
Perform heating.

In the ceiling-embedded humid air conditioner configured as described above, the filter 6 is positioned above the top panel 5 disposed on the exposed panel 2, and the filter 6 is formed smaller than the top panel 5. Therefore, unlike conventional ceiling-mounted humid air conditioners, dust does not fall into the room from the filter 6 when the operation is stopped, but is collected by the top panel 5, making it sanitary. As shown in the figure, the cut window 5a and the filter 6 themselves are covered with dust from the indoor air.
Since the filter 6 is not visible from the ventilation path a and is not exposed on the indoor side, the initial aesthetic appearance is not spoiled.

In addition, since the exposed panel 2 and the main body 1 in the ceiling are connected in the space of the passages 18 and 1B formed on both sides of the top panel, there is no need to open or close the top panel 5.
It is possible to attach and detach the exposed panel 2 from the ceiling surface,
Therefore, when performing service work such as cleaning the blower 10 and the dew pan 12, the work efficiency is improved and the work can be performed safely.

As described above, this invention forms air ventilation paths on both sides of the top panel attached to the air intake port, and forms an air ventilation path between the top panel and the filter installed above the top panel. Therefore, even if dust in the air sucked in from the room falls from the filter when the operation is stopped, it will be caught by the top panel, which is sanitary.

Furthermore, since the filter is not exposed indoors, it is possible to obtain effects such as not spoiling the aesthetic appearance.
