Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ceiling-suspended cassette type air conditioner installed in the attic of various buildings.

[Conventional technology]

Conventional air conditioners of this type are installed in the attic during the construction of a building, and have a configuration in which a ventilation duct provided from an air outlet is guided to each room and opened into each room.

[Problem that the invention attempts to solve]

The conventional air conditioners mentioned above were installed in the attic during the construction stage of the building, so when inspecting and maintaining the inside of the building, workers had to climb up to the attic through the ceiling entrance and then enter the air conditioner, creating a cramped space. Inspections and maintenance had to be carried out in an awkward position, which was painful and resulted in poor work efficiency.

This invention eliminates the above drawbacks,
It is characterized by being economical and allowing for easy and quick internal inspection and maintenance.

[Means for solving problems]

In order to eliminate the above-mentioned drawbacks, this invention has an inlet at one end and an outlet at the other end, and a filter zone, piping zone, hot and cold water coil zone, and fan zone in the passage from the inlet to the outlet. However, the filter unit, piping unit, cold and hot water coil unit, and fan unit are installed in the filter zone, piping zone, cold and hot water coil zone, and fan zone, avoiding the use of their bottom parts, and excluding the cold and hot water coil zone. An inspection door is provided on each bottom surface, and an appropriate number of hanging brackets are protruded from both sides of the bottom surface.

[Effect]

The present invention is suspended and supported in the attic by using an appropriate number of hanging brackets 20 arranged on both sides of the bottom.

In the present invention, inspection doors 17, 18, and 19 are provided at the bottoms 6, 8, and 11 of the filter zone A, piping zone B, and fan zone D, excluding the cold/hot water coil zone C.

They can be easily constructed because the filter unit 3, piping unit 4, and fan unit 5 are provided therein while avoiding the use of the bottom portions 6, 8, and 11 of each zone as much as possible.

Therefore, in the present invention, the above-mentioned inspection doors 17, 18
and 19, maintenance and inspection of the device can be performed easily and quickly.

In other words, there is no need to climb up to the ceiling from the ceiling entrance and enter the air conditioner, as in the past, by removing the ceiling panels 22 that are deemed necessary and opening the inspection doors 17, 18, and 19 that are deemed necessary. It can be opened and used to quickly work from the floor using a ladder or stepladder while standing up.

〔Example〕

The drawings show one embodiment of the present invention, and the details thereof will be explained below.

In the figure, reference numeral 1 indicates an inlet which is constructed at one end of the main body H and introduces outside air, etc., and reference numeral 2 indicates an outlet to which a ventilation duct (not shown) is connected to each chamber.

In the present invention, a filter zone A, a piping zone B, a cold/hot water coil zone C, and a fan zone D are sequentially constructed in the passage from the suction port 1 to the blowout port 2.

A filter unit 3, a piping unit 4, and a fan unit 5 are provided in the filter zone A, piping zone B, cold/hot water coil zone C, and fan zone D, with the bottom portions thereof being avoided as much as possible.

That is, the filter unit 3 consists of a pre-filter 3a, a medium-performance filter 3b, etc., and these are not provided from the bottom surface 6 of the filter zone A, but from the partition plate 7 provided between the filter zone A and the piping zone B.

Next, the piping unit 4 consists of a cold and hot water inlet 4a, a cold and hot water outlet 4b, a two-way cold and hot water valve 4c, etc.
They are not provided from the bottom part 8 of the piping zone B, but from the partition plate 10 provided between the side plate 9 and the cold/hot water coil zone C.

The fan unit 5 is composed of a fan 5a, a drive motor 5b, etc., and the drive motor 5b is provided on the bottom part 11 of the fan zone D.
I try to avoid using 1 as much as possible.

Next, regarding the cold/hot water coil zone C, in the embodiment shown in the drawings, a drain pan 13 is provided over the entire bottom portion 12, and a cold/hot water coil unit 14 and a steam humidifier 15 are provided above the drain pan 13. . Therefore, no inspection door is provided.

In the figure, 15a is a steam two-way valve that constitutes the steam humidifier 15.

The present invention further includes the filter zone A,
Bottom portions 6, 8 of piping zone B and fan zone D
and 11 are provided with inspection doors 17, 18, and 19.

The inspection doors 17, 18 and 19 are as described above.
Since the filter unit 3, piping unit 4, and fan unit 5 are provided so as to avoid using the bottom portions 6, 8, and 11 of the filter zone A, piping zone B, and fan zone D as much as possible, the structure can be easily configured.

Furthermore, an appropriate number of hanging brackets 20 are provided to protrude from both sides of the bottom surface. In the figure, 21 is a suspension rod, and 22 is a ceiling board.

As shown in FIGS. 2 and 3, the present invention having the above-mentioned structure is installed in the attic by means of hanging rods 21 using hanging brackets 20, and a removable ceiling plate 22 is provided on the lower surface thereof.

Therefore, for inspection and maintenance, remove the ceiling panels 22 that are considered necessary, and install the inspection doors 17 and 18 that are considered necessary.
This can be done quickly from the floor using a ladder or stepladder, etc., while standing up. There is no need to work in a posture.

[Effect of idea]

According to the present invention, internal maintenance and inspection can be performed easily and quickly, and an economical effect can be obtained.
