BACKGROUND

1. Field

The present disclosure relates generally to a duct type air conditioning device, and more particularly to a duct type air conditioning device which reduces the number of fastening screws that are used to connect a blowing portion and a heat exchanging portion to each other and intercepts air leakage that occurs in a connection portion between the blowing portion and the heat exchanging portion in an indoor unit of a ceiling embedded duct type air conditioning device in a state where the blowing portion and the heat exchanging portion are mutually connected to each other.

2. Description of the Related Art

In general, as illustrated inFIG. 1, an indoor unit of a ceiling embedded air conditioner that is installed to be embedded in the ceiling of a building is composed of a heat exchanging portion10including a first box-shaped cabinet3having a heat exchanger1built therein, a blower assembly11sucking and blowing indoor air toward the heat exchanger1, and a blowing portion20including a second cabinet13having the blower assembly11built therein.

The blower assembly11is installed on a partition panel30partitioning the first and second cabinets3and13, and a pair of fan casings11ais coupled to a ventilation port31of the partition panel30. A pair of blowing fans11bis installed inside the pair of fan casings11a. A motor (not illustrated) for driving the pair of blowing fans11bis arranged between the pair of fan casings11a.

The above-described blower assembly11is fixed to the first cabinet3through fastening of a plurality of fixing screws along the circumference of the partition panel30in a state where the partition panel30comes in close contact with the first cabinet3.

On the other hand, if the blowing fan11b, the motor, or the heat exchanger1gets out of order while using the indoor unit of the air conditioner in the related art that is installed to be embedded in the ceiling, an upper plate3aof the first cabinet3or an upper plate13aof the second cabinet13may be separated for repairs. In this case, the repairing work time may be lengthened due to a large number of fixing screws40that are used to fix the upper plate.

Because the upper plate3aof the first cabinet3is constructed to be directly fastened to the partition panel30simply by the fixing screws40, an airtight seal may not be properly kept in a connection portion between the upper plate3aof the first cabinet3and the partition panel30to cause air leakage to occur in the connection portion.

Further, according to a duct type air conditioner in the related art, in order to connect a coupling portion that is formed at a lower end of the cabinet on the side of the heat exchanging portion into a coupling groove that is formed at a lower end of the cabinet on the side of the blowing portion for mutual connection between the blowing portion and the heat exchanging portion, it is required to insert the coupling portion of the cabinet on the side of the heat exchanging portion into the coupling groove of the cabinet on the side of the blowing portion after lifting the cabinet on the side of the heat exchanging portion with a predetermined height.

However, because the blowing portion and the heat exchanging portion are heavy, at least two workers are necessary to perform the connection work. In addition, a large number of fixing screws are used to connect the respective cabinets on the sides of the blowing portion and the heat exchanging portion. Due to this, workability is considerably deteriorated.

SUMMARY

The present disclosure has been made to address at least the above problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure provides a duct type air conditioning apparatus, which may minimize the number of fixing screws that are used to connect a blowing portion and a heat exchanging portion to each other and keep an airtight seal in a connection portion between the blowing portion and the heat exchanging portion.

An aspect of the present disclosure provides a duct type air conditioning apparatus, which may facilitate connection and disconnection of a blowing portion and a heat exchanging portion.

According to an aspect of the present disclosure, a duct type air conditioning apparatus, provided with a blowing portion including a first cabinet in which a blower assembly is installed and a heat exchanging portion including a second cabinet in which a heat exchanger is installed, includes a partition panel arranged between the first and second cabinets and connected to facing sides of the first and second cabinet; and first and second link members separably fastened along an upper end and a lower end of the partition panel to keep an airtight seal in a connection portion between the first and second cabinets.

Each of the first and second link members may include a center portion separably connected to the partition panel; a first extension portion extending toward the first cabinet; and a second extension portion extending toward the second cabinet, wherein the first and second extension portions of the first and second link members come in close contact with upper and lower plates of the first and second cabinets to form multiple airtight points.

The first and second extension portions of the first and second link members may be inserted into first and second groove portions that are formed on the upper and lower plates of the first and second cabinets in a state where the first and second extension portions are circumscribed on the first and second groove portions.

The first and second extension portions may be formed to be bent in multistage or to be curved in a winding shape.

The first and second extension portions may be arranged to be inclined in a flat plate shape.

Upper plates of the first and second cabinets may simultaneously come in close contact with the first link member and an upper end portion of the partition panel, and lower plates of the first and second cabinets may simultaneously come in close contact with lower end portions of the second link member and the partition panel.

Upper plates and lower plates of the first and second cabinets may respectively come in close contact with upper end portions and lower end portions of frames of the first and second cabinets to form multiple airtight points.

Locking portions may be formed on the upper end portions and the lower end portions of the frames of the first and second cabinets to project toward the upper plates and the lower plates of the first and second cabinets, and groove portions may be formed on the upper plates and the lower plates of the first and second cabinets so that the locking portions of the respective frames are inserted into the groove portions. In this case, the locking portions may be circumscribed on the groove portions.

Each of the first and second link members may include a center portion separably connected to the partition panel; a first extension portion extending toward the first cabinet; and a second extension portion extending toward the second cabinet, wherein any one of the first and second extension portions is integrally formed on upper and lower plates of the first and second cabinets and the other of the first and second extension portions comes in close contact with other upper and lower plates of the first and second cabinets to form multiple airtight points.

According to an aspect of the present disclosure, a duct type air conditioning apparatus, provided with a blowing portion including a first cabinet in which a blower assembly is installed and a heat exchanging portion including a second cabinet in which a heat exchanger is installed, includes a partition panel arranged between the first and second cabinets and connected to facing sides of the first and second cabinet; and at least one link member separably fastened along at least one of an upper end portion and a lower end portion of the partition panel to make an airtight seal in a connection portion between the first and second cabinets in multiple ways.

Both sides of the at least one link member may be inserted into groove portions formed on any one of upper and lower plates of the first and second cabinets in a state where the both sides of the at least one link member are inscribed on the groove portions.

At least one of upper and lower plates of the first and second cabinets may come in close contact with upper end portions or lower end portions of frames of the first and second cabinets to form multiple airtight points.
