DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater assembly for an air conditioner, and more particularly, to a heater assembly for an air conditioner having a detachable heater unit and having a variable heating capacity.

[0002]

2. Description of the Related Art An air conditioner is a device for controlling the temperature, humidity, etc. of indoor air in order to compose a comfortable indoor environment. For the heater.

An example of such an air conditioner is shown in FIG. The air conditioner 101 includes an outer casing 103 forming an external appearance, a suction cover 105 provided at a lower portion of a front surface of the outer casing 103 and having a suction port 109, an operation cover 111 provided above the suction cover 105 and having an operation panel 113, and A discharge cover 115 having a discharge port 117 is provided above the operation cover 111. The air in the room is sucked into the outer casing 103 through the suction port 109, and the air in the outer casing 103 is discharged into the room through the discharge port 117.

The discharge cover 115 is provided with a vertical steering blade 119 rotatable about a horizontal axis and a horizontal steering blade 121 rotatable about a vertical axis. The vertical steering blade 119 adjusts the vertical discharge direction of the air discharged through the discharge port 117, and the horizontal steering blade 121 controls the horizontal discharge direction of the air discharged through the discharge port 117. .

[0005] The inner space of the outer casing 103 is partitioned by a separation plate 127 into a pair of heat exchange chambers 128 and 129, that is, a lower cooling chamber 128 and an upper heating chamber 129. A cooling system (not shown) is provided in the cooling chamber 128, and a heating device 130 is provided in the heating chamber 129.

An air duct 123 is provided below the separation plate 127.
The air duct 123 is provided with a blower fan (not shown). Both sides of the air duct 123 are opened so as to communicate with the cooling chamber 128, and the upper surface is opened so as to communicate with the heating chamber 129.

When the air conditioner 101 operates in the cooling mode, the cooling system and the blower fan operate, and the heating device 13 operates.
0 does not work. Therefore, the air drawn into the cooling chamber 128 through the suction port 109 is cooled by the cooling system and then flows into the air duct 123. Air duct 1
Cooled air in the heating chamber 12 is blown by the blower fan.
9 and discharged into the room through a discharge port 117. Along with this, the cooling operation of the indoor air is performed.

On the other hand, when the air conditioner 101 operates in the heating mode, the heating device 130 and the blower fan operate, and the cooling system does not operate. Therefore, the cool air sucked into the cooling chamber 128 through the suction port 109 flows into the air duct 123 and is then supplied into the heating chamber 129 by the blower fan. The air is heated in the heating chamber 129 by the heating device 130, and the heated air is discharged into the room through the discharge port 117. Accordingly, the heating operation of the indoor air is performed.

In the air conditioner 101 as described above, there is a problem that it is difficult to adjust the heating intensity because the heating capacity of the heating device 130 is constant. That is, since the heater provided in the heating device 130 always emits a certain amount of heat, the heating capacity of the heating device 130 does not substantially change, and the air conditioner 101
Adjusts the heating intensity by rotating the blower fan at a speed proportional to the heating temperature set by the user. Therefore, when the temperature set by the user is low, the set temperature is reached within a short time, and when the set temperature is high, it takes a long time to reach the set temperature.

[0010]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a heater assembly for an air conditioner which can easily change the heating capacity in consideration of the conventional problems. is there.
