Description

A multi-division indoor unit of air-conditioner

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to an indoor unit of a multi-part split type air conditioner, in which a plurality of blowing fans are installed in a lateral direction, and a front frame and a suction grill are divided into a plurality.

In general, the air conditioner is to process the intake air to supply the building or the room to maintain the indoor air in a comfortable condition at all times, largely divided into (window type) and separate type (seperate type or split type).

The one-piece type and the separate type are functionally the same, but the one-piece type integrates the function of cooling heat dissipation, and is directly installed by drilling a hole in a wall of a house or by hanging a device on a window. And a compression device to connect the two devices separated from each other by a refrigerant pipe.

The air conditioner as described above is mainly composed of an indoor unit performing a cooling function, an outdoor unit performing a heat dissipation and compression function, and a refrigerant pipe connecting the indoor unit and the outdoor unit to each other.

1 is an exploded perspective view showing the internal structure of a separate air conditioner indoor unit according to the prior art, referring to this, the indoor unit of the conventional separate air conditioner includes a chassis 20 fixed to a wall; It is coupled to the front surface of the chassis 20 to form a receiving space of the heat exchanger 49, the blowing fan 40 and the motor 42 together with the chassis 20, the inlet 12 is formed on the upper surface, A front frame 10 having a discharge port 14 formed on the lower surface of the front surface; It is configured to include a suction grill 30 rotatably coupled to the front of the front frame 10, the suction port 32 is formed.

One blower fan 40 is positioned in the transverse direction in front of the chassis 20, and the blower fan 40 is rotatably supported by a support part 24 protruding perpendicularly to the front of the chassis 20. It is supported, and the heat exchanger 49 is located in a bent shape in front of and above the blowing fan 40.

The condensate receiving part 44 is formed at an upper portion of the lower side of the heat exchanger 49 to collect the condensed water flowing down from the heat exchanger 49, and the left and right wind directions of the air discharged to the discharge port 14 at the lower portion thereof. The discharge grill 45 is provided with a louver 45a for adjusting the vane 46b and a vane 46b for adjusting the up and down wind direction of the air discharged to the discharge port 14.

The front frame 10 includes a plurality of filters for filtering bulky foreign matter from the air sucked into the air conditioner through the suction port 32 of the suction grill 30 and the suction port 12 of the front frame 10. An air filter 36 and a plurality of dust collectors 38 for ionizing and removing dust in the air passing through the air filter 36 are mounted.

The chassis 20 is formed with a flow path portion 22 forming a flow path of air flowing by the blowing fan 40, the motor for driving the blowing fan 40 on one side of the blowing fan 40 42 is connected, and the control unit 46 is installed on the front side of the motor 42 is installed various electric components (not shown) for the operation of the air conditioner.

In the indoor unit of the conventional separate type air conditioner configured as described above, the indoor air sucked through the suction ports 12 and 32 is cooled through heat exchange with the refrigerant while passing through the heat exchanger 49, and the air thus cooled After passing through the blower fan 40 is guided to the flow path portion 22 is discharged into the room through the discharge port (14).

However, the structure of a conventional separate type air conditioner indoor unit using one blower fan 40 as described above, when designed to be applied to a large-capacity air conditioner system, the blower fan 40 and the heat exchanger 49 When the length of the blower fan 40 is increased, the length of the blower fan 40 is not only difficult to manufacture the blower fan 40, but there is a great problem that the middle part sags or breaks due to its own weight. In addition, the long blower fan 40 has a problem that the operation is very unstable due to the sag during rotation, and at the same time there is a risk of being damaged by contact with the flow path 22 or the condensate receiver 44.

Similarly, when the length of the heat exchanger 49 is increased, the heat exchanger 49 sags due to its own weight. When the heat exchanger 49 sags in this way, a gap between the blower fan 40 and the heat exchanger 49 may be reduced. As the distance gets closer, there is a problem that the probability of contacting each other becomes high.

As the length of the heat exchanger 49 and the blower fan 40 increases, the suction grill 30 and the front frame 10 also need to be increased in length, and the injection into the integrated body is not easy. There is a problem.

In addition, even if the suction grill 30 and the front frame 10 are integrally injected long, the air filter 36 needs to be cleaned, or due to a failure of the dust collector 38, the suction grill (for the repair work) 32) When the suction grill 30 is integrally formed, the suction grill 30 is integrally formed, and when the suction grill 30 is opened, all of the electrical components or the motor 42 installed in the controller 46 are broken. There is an inconvenience in that the suction grill 30 and the entire front frame 10 must be separated from the chassis 20 for repair.

The present invention has been made in order to solve the above problems of the prior art, it can be applied to a large-capacity air conditioner by inhaling and discharging a larger amount of air than when inhaling and discharging indoor air with one blower fan Another object of the present invention is to provide an indoor unit of a multi-part split type air conditioner that can prevent the central portion of the blower from sagging.

In addition, it is an object of the present invention is to conveniently open only a part of the front right side of the indoor unit, not opening all when opening the front of the indoor unit due to failure of the motor or electrical components.

In addition, when the length of the front frame and the suction grill is increased to be applied to a large-capacity air conditioner, there is an effect that can solve the problem that it is difficult to inject the front frame and the suction grill integrally long.
