[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention integrates a blower and an electric motor for the blower to facilitate attachment / detachment to / from an air conditioner main body.
The present invention also relates to a ceiling-embedded air conditioner that can be easily cleaned.

[0002]

2. Description of the Related Art An air conditioner has been provided in offices, hospitals, various stores, ordinary households, etc. for the purpose of comfortable air conditioning. As one of the air conditioners, there is known a so-called ceiling-embedded type that is buried in the ceiling to secure a space in the room. As shown in FIG. 2, this is composed of a main body 1 that houses a blower 8 suspended by bolts (not shown) in the ceiling, a heat exchanger 3 and the like, and an indoor panel 6 exposed to the indoor side. ing. As shown in FIG. 2, the partition between the heat exchanger chamber 14 of the ceiling-embedded air conditioner and the air inflow side to the blower is a blower 8, and the blower motor 7 is a fixed partition plate 17. It is installed. Therefore, the blower 8 and the blower motor 7 cannot be attached or detached in the assembled state.

[0003]

In such a ceiling-embedded air conditioner, the fins of the heat exchanger are not contaminated or clogged with dust and the dust accumulated on the drain pan is operated for a considerable period of time. Needs to be cleaned to remove. Further, it may be necessary to perform maintenance on the blower and the blower electric motor. However, in the conventional structure as shown in FIG. 2, when cleaning the heat exchanger 3 and the drain pan 4 from the indoor side panel 6 side, even if the blower 8 and the blower electric motor 7 are removed, the opening of the discharge part of the blower 8 is Although it can be obtained, it is not possible to obtain a sufficient opening area for work,
Cleaning work was very difficult. In addition, when performing maintenance for replacement of the blower 8 and the electric motor 7 for the blower, due to the nature of the ceiling-embedded air conditioner, work is performed at high places. It was very difficult.

An object of the present invention is to facilitate cleaning of a heat exchanger of a ceiling-embedded air conditioner and maintenance of a blower and a blower electric motor.

[0005]

In order to achieve the above object, the present invention provides a ceiling-embedded air conditioner with a detachable structure for the partition between the heat exchanger room side and the air inflow side to the blower. The gist is that a blower and a blower electric motor are attached to the removable partition plate to form a blower assembly.

[0006]

[Function] When cleaning the heat exchanger, etc., a large opening to the heat exchanger chamber can be obtained by removing the blower assembly, and the blower assembly can be easily used for maintenance of the blower and the electric motor for the blower. Since it can be removed, cleaning and maintenance work can be performed easily and reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A ceiling-embedded air conditioner of the present invention will be described below with reference to the illustrated embodiments. In the figure, 1 is a main body of an air conditioner, and the main body 1 has a heat exchanger 3, a blower 8,
The fan electric motor 7 and the like are housed therein and are suspended by suspension bolts (not shown). The interior panel 6 provided with the air filter 10 and the like is attached to the main body 1 by adjusting the height with the ceiling plate 9.

The air sucked from the suction port 11 of the indoor panel 6 passes through the air filter 10, is introduced into the heat exchange chamber 14 by the blower 8 and is air-conditioned by the heat exchanger 3, and the air outlet 1
Air is supplied to the room or the like from 2 through the outlet duct 13.

The blower 8 and the blower electric motor 7 are attached to the removable partition plate 2 to form a blower assembly 16, and the blower assembly 16 is attached to the support column 5 attached to the main body 1 by the mounting screw 15. Has been. Further, a drain pan 4 for receiving condensed water generated during the cooling operation is attached to the lower part of the heat exchanger 3 by a column 5.

The air passing through the heat exchanger 3 contains fine dust that cannot be removed by the air filter 10, and adheres to the fins of the heat exchanger 3 during a considerable period of operation. It is deposited on the drain pan 4. Therefore, when the heat exchanger 3 and the drain pan 4 are cleaned, the heat exchanger chamber 14 is largely opened by removing the blower assembly 16, so that the heat exchanger chamber 14 can be easily cleaned by a method such as washing with water.

After the cleaning work is completed, the blower assembly 16 is attached, but the blower 8 is attached when the blower assembly 16 is attached or detached.
Also, since it is not necessary to remove the fan motor 7, it is not necessary to perform centering work for the fan 8 and the fan motor 7.

When the blower 8 or the blower electric motor 7 is replaced, the blower assembly 16 is removed as in the case of the above-mentioned cleaning, and the blower assembly 16 is attached and detached in a workable condition such as on a workbench or a floor. , Exchange and centering work can be performed.

[0013]

[Effect of the Invention] According to the ceiling-embedded air conditioner of the present invention,
It has the following effects. (1) Improvement of workability Conventionally, it was very difficult to clean the heat exchanger etc. from the indoor panel side, but the structure of the present invention provides a large opening, which facilitates the work and also the work of cleaning the heat exchanger etc. Since it is not necessary to separate the blower and the blower electric motor from time to time, it is not necessary to reassemble the blower and the blower electric motor. Further, conventionally, the work such as the replacement of the blower or the electric motor for the blower has been an upward work at a high place, but with the structure of the present invention, the work can be performed at a place where the work is easy. (2) Improvement of safety Since the blower and the electric motor for the blower can be detached and the centering work can be performed on a workbench or a floor, which has been a work at a high place in the past, the work is safe.
